Top 3 Reasons Why You Should Have a Dehumidifier at Home

Air quality is one of those things that many homeowners frequently overlook. We assume that the air indoors is better or less polluted than the air outdoors because we’re not dealing with things like car fumes and pollution.

However, your indoor air can be just as bad as the atmosphere outdoors, particularly when you have problems with humidity. Too much humidity in your air can increase the risk of things like respiratory problems, mould, and even an overflow of dust. Here are 3 reasons to consider bringing a dehumidifier into your property.

1. They Combat Mould, Mildew and Dust

Damp in your home caused by humidity can lead to mould and mildew. Often, these problems are the root cause of health issues, such as asthma, respiratory conditions, and asthma. What’s more, constant exposure to mildew and mould may even increase your chances of nervous system disorders.

Taking steps to avoid your risk of moisture build-up by keeping your sewer line clear and fixing leaky pipes is great. However, homeowners can consistently keep their risk to a minimum by investing in a dehumidifier. These crucial tools remove the extra unnecessary moisture from the air, so that it can no longer feed mould spores in your home.

Having a dehumidifier can also help you to get rid of other pesky substances like dust on your mattresses, bedspreads, and other furniture too. That’s because it’s easier for dust to cling to your surfaces when there’s moisture in the air. When the air is dry, regularly vacuuming your home will get rid of a larger portion of dust, keeping the risk of allergy to a minimum. Dehumidifiers even eliminate the risk of dust mites by keeping humidity levels at a inhospitable level for those critters.

2. They Reduce Damp and Condensation

Too much humidity in your home causes a “damp” atmosphere. When the air is moist, the most obvious result is discomfort. You might notice that your breathing feels more laboured just because you’re breathing moisture-laden air. Damp doesn’t just stay in the air however, when it reaches excessive levels, it also begins to build up on the surfaces around your home, particularly in the winter when the cold of the outdoors interacts with the warm humidity indoors.

Humidity causes long-term damage to your woodwork and soft furnishings through damp and condensation. Although it’s common to have condensation in your home from time to time, humidity exacerbates it to dangerous levels, potentially causing peeling wall papers, shrinking wood, and stains on your sofas and curtains.

A dehumidifier will reduce the moisture in the air to reasonable levels again, protecting your belongings and your comfort.

3. They Improve Air Quality for Better Health

Finally, the most important reason to invest in a dehumidifier is that they allow you to improve your air quality and eliminate common health problems. Humidity in your home can lead to an increased risk of respiratory conditions, allergens, and even problems with coughs and stuffy noses. As mould and mildew begin to build up, the effects on your health grow even greater.

Placing a dehumidifier into your home does more than just get rid of musty smells throughout your property. It also absorbs the excess moisture that could be harming your health over time. Remember, the quality of the air in your home isn’t just measured by the amount of toxins that you could be exposed to. Your air quality also depends on the level of humidity in the air too.

Dry air is less likely to feed the bacteria in the atmosphere, reducing your risk of catching bugs and respiratory illnesses. According to studies, dehumidifiers are even useful in preventing asthma attacks because they remove asthma triggers like dust mites, mould, VOCs and building wastes.

Should You Get a Dehumidifier?

In a world where indoor air quality isn’t much better than the polluted air that we find outside, it’s important to take steps to protect yourself, your family and even your home. A dehumidifier can help you to improve the air quality that you’re exposed to every day.

By eliminating the unnecessary moisture in your home, your domestic dehumidifier will improve your quality of life, reduce the risk of mould and mildew, and even protect your health.

The Importance of Indoor Air Quality Monitoring

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.

Health Impacts of Air Pollutants

Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable.

Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution, if it can be identified. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened.

The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and preexisting medical conditions. In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures.

In long-term effects, other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.

Reasons for Poor Indoor Air Quality

Gas and respirable particulates in the air are the primary sources that contribute to poor IAQ. Sources can include inadequate ventilation, poorly maintained HVAC systems, cooking stoves, non-vented gas heaters, tobacco smoke, vehicle exhaust emissions, building materials, carpeting, furniture, maintenance products, solvents, cleaning supplies, window furnishings and floor rugs. You can view this study here about how indoor VOC’s likely contribute to asthma and allergies.

Thermocouples: Types and Uses

Thermocouples are sensors used to measure temperatures. These devices consist of different metals to form two wire legs forming a junction. Manufacturers weld together these two wire legs to make sure the connection is stable. Thermocouple junctions are used to check for changes in temperatures. There are different types of thermocouples available in the market, and these models have distinct characteristics and features.

The Types of Thermocouples

The manufacturing of a thermocouple requires producers to classify units with distinct color codes. Manufacturers classify these codes in either ANSI/ASTM E230 OR IEC60584. The thermocouples, their calibrations, and their color designations (in ANSI/ASTM E320) are:

  • Type K: Yellow (+) / Red (-)
  • Type T: Blue (+) / Red (-)
  • Type N: Orange (+) / Red (-)
  • Type S: Black (+) / Red (-)
  • Type C: N/A
  • Type J: White (+) / Red (-)
  • Type E: Purple (+) / Red (-)
  • Type R: Black (+) / Red (-)
  • Type B: Black (+) / Red (-)

Conversely, here are the thermocouples once more and their calibrations, but with their IEC 60584 color designations:

  • Type K: Green (+) / White (-)
  • Type T: Brown (+) / White (-)
  • Type N: Rose (+) / White (-)
  • Type S: Orange (+) / White (-)
  • Type C: N/A
  • Type J: Black (+) / White (-)
  • Type E: Purple (+) / White (-)
  • Type R: Orange (+) / White (-)
  • Type B: Orange (+) / White (-)

Thermocouple Temperature Range

Aside from the color codes, thermocouple types have specific melting points and continuous maximum temperatures. For example, the thermocouple Type B with a platinum 30% rhodium (+) composition may have a temperature range of 2,500 to 3,100 degrees Fahrenheit. Conversely, a platinum 6% rhodium (-) composition of the same thermocouple type may yield a similar temperature range.

Another example is a thermocouple type E with a chromel (+) composition. For this model, you may use it for handling temperature ranges of 200 to 1,650 degrees Fahrenheit. Still, consider the environment before using specific thermocouple types.

Uses of Thermocouples

Different thermocouple types may have diverse uses. Hospital thermometers, automotive technologies, and machines handling renewable energies might use thermocouples to help users detect changes in temperatures. Here are a few thermocouple types and their uses:

  • Type J

This thermocouple type may have an iron and Constantan leg. Various organizations in different industries find this model to be helpful in several operations. For example, it may be useful in reducing, oxidizing, and vacuuming atmospheres. Type J models may have durable constructions. Thus, these units may not require sensitive handling when installing them in other machines or industrial environments.

  • Type K

This thermocouple has a Chromel and Alumel composition for its wire legs. Consider using this type to oxidize or inert atmospheres with temperatures of up to 2,300 Fahrenheit. Companies may use this thermocouple model thanks to its relatively accurate and stable readings even at high temperatures.

  • Type N

Type N thermocouples may be akin to better Type K models. This type has a Nicrosil and Nisil composition for its wire legs. It also has a similar temperature range as the Type K. However, type N models might have better resistance than its type K counterparts thanks to its temperature cycling features. Furthermore, its hysteresis and green rot allow type N models to be more cost-effective units than type Ks.

  • Type T

A copper and Constantan composition reside in the wire legs of type T thermocouples. Like the type J models, type Ts help users reduce, oxidize, vacuum, and inert atmospheres. Still, this thermocouple class has excellent resistance against corrosion in several atmospheres. It may also offer high-stability readings at sub-zero temperatures.

  • Type E

For this thermocouple, it has one Chromel and one Constantan leg. Like the type T thermocouple, it may also be resistant to corrosion in various atmospheres. However, there’s one characteristic that may put type E thermocouples better than other models: Type Es may have the highest EMF per degree in comparison with different thermocouple types. Nonetheless, it might not be resistant to sulfurous environments.

  • Type C

Environments that have sweltering temperatures may use type C thermocouples. This model has a tungsten and rhenium composition for its wire legs. Organizations may use this thermocouple type in extremely high-temperature environments of up to 4,200 degrees Fahrenheit. While it can withstand high temperatures, this thermocouple may have a brittle construction. Proceed with caution when handling it as one false move might break the device.

Conclusion

Always consider the right thermocouple type when you want to read temperatures accurately in specific environments. For instance, consider the right thermocouple when reading temperature levels in automotive technologies and their hot engines. These devices may also activate gas shut-off modules aside from reading temperatures. Take time in researching the right model for the job to avoid complications.

Collection Systems for Agricultural Biomass

Biomass collection involves gathering, packaging, and transporting biomass to a nearby site for temporary storage. The amount of biomass resource that can be collected at a given time depends on a variety of factors. In case of agricultural residues, these considerations include the type and sequence of collection operations, the efficiency of collection equipment, tillage and crop management practices, and environmental restrictions, such as the need to control soil erosion, maintain soil productivity, and maintain soil carbon levels.

biomass-collection-systems

The most conventional method for collecting biomass is baling which can be either round or square. Some of the important modern biomass collection operations have been discussed below:

Baling

Large square bales are made with tractor pulled balers. A bale accumulator is pulled behind the baler that collects the bales in group of 4 and leaves them on the field. At a later date when available, an automatic bale collector travels through the field and collects the bales.

The automatic bale collector travels to the side of the road and unloads the bales into a stack. If the automatic bale collector is not available bales may be collected using a flat bed truck and a front end bale loader. A loader is needed at the stack yard to unload the truck and stack the bales. The stack is trapped using a forklift and manual labor.

biomass-collection

Loafing

When biomass is dry, a loafer picks the biomass from windrow and makes large stacks. The roof of the stacker acts as a press pushing the material down to increase the density of the biomass. Once filled, loafer transports the biomass to storage area and unloads the stack. The top of the stack gets the dome shape of the stacker roof and thus easily sheds water.

Dry Chop

In this system a forage harvester picks up the dry biomass from windrow, chops it into smaller pieces (2.5 – 5.0 cm). The chopped biomass is blown into a forage wagon traveling along side of the forage harvester. Once filled, the forage wagon is pulled to the side of the farm and unloaded. A piler (inclined belt conveyor) is used to pile up the material in the form of a large cone.

Wet Chop

Here a forage harvester picks up the dry or wet biomass from the windrow. The chopped biomass is blown into a forage wagon that travels along side of the harvester. Once filled, the wagon is pulled to a silage pit where biomass is compacted to produce silage.

Whole Crop Harvest

The entire material (grain and biomass) is transferred to a central location where the crop is fractionated into grain and biomass.  The McLeod Harvester developed in Canada fractionates the harvested crop into straw and graff (graff is a mixture of grain and chaff). The straw is left on the field. Grain separation from chaff and other impurities take place in a stationary system at the farmyard.

McLeod Harvester fractionates the harvested crop into straw and graff

For the whole crop baling, the crop is cut and placed in a windrow for field drying. The entire crop is then baled and transported to the processing yard. The bales are unwrapped and fed through a stationary processor that performs all the functions of a normal combine. Subsequently, the straw is re-baled.

Why it is Important to Recycle Used Filters and Oil

Illegally or inappropriately disposed of used motor oil can have a grievous impact on the environment. Studies conducted indicate that a single gallon of used oil can pollute up to a million gallons of water. Used oil filters are made of steel which means they can be recycled. In some developed countries, they are the most recycled materials and dumping them in landfills is illegal in other countries, while some have stringent laws that define how they should be disposed of.

Regulatory organizations such as the environmental protection agency reiterate that used oil filters should only be recycled or disposed of once all the free flowing oil has been drained. Presently, oil filters manufactured in the United States are not subject to dangerous waste regulation provided the filter is:

  • Hot drained then crushed
  • Broken through the anti drain valve or the dome and hot drained
  • Hot drained then dismantled

Hot draining is the process of draining the oil filter near or at engine operating temperature above 60ºF. Basically, the filter is either crushed or punctured while still warm in order to clear any surplus oil. The environmental protection agency recommends hot draining for up to 12 hours.

While lubricating oil hardly wears out, it gets dirty. Foreign bodies such as chemicals, water, dirt or even metal scrapings can mix with it and lower its performance capability. Contaminated oil should be replaced either with re-refined or virgin oil in order to execute its job appropriately.

The contaminated oil can be taken through used oil recycling procedures with studies indicating that approximately 380 million gallons of contaminated oil are recycled annually. Recycled oil is often taken through immense re-refining to eliminate all the impurities in order to produce pure oil.

The end product referred to as re-refined oil should fit similar rigorous compounding, refining, and performance principles as pure motor oil. Re-refining is an environmentally and energy valuable method of managing used motor oil. Producing a gallon or re-refined base stock requires less energy that producing crude oil base stock.

Advantages of Recycling Used Filters and Oil

Oil re-refining helps reduce heavy metal emissions and greenhouse gases as opposed to combusting it as fuel. Re-refining is an ideal way of managing used motor oil, it is environmentally friendly, and converts used oil into a renewable resource. Re-refining used motor oil reduces a nation’s reliance on foreign crude oil.

Used motor oil filters contain oil at the time of disposal. Having the ideal recycling company recover them ensures that the oil is recovered and re-refined. This also helps safeguard landfill space.

Collection of Materials

The manufacturers of oil tanks and filters are responsible for the materials. Many times, they provide big containers for disposing of the used filters especially in large volume shops. Recycling companies however can provide bins or drums for used filters while the shops provide waste oil storage facilities.

While used oil tanks will not be replaced when service providers are changed, shop managers must analyze the state of their used oil storage facilities to rule out spillage or loss when oil is transferred to an oil truck.

If need be, many recycling companies can also provide storage facilities. Used oil filters do not necessarily have to be crushed or drained before being recycled provided they are kept in a bin or drum.

What Next?

Oil filters are broken down into small fragments while the metals are removed and sold as scrap. Eventually, they are used to manufacture various products such as manhole covers and rebar. The contaminated oil is sold recycling companies. A huge percentage of the used oil is refined, drained, and used as an energy alternative to natural gas while the remaining percent is processed into hydraulic oil.

Finally

Used oil can be detrimental to water bodies and the environment in general. Companies should incorporate stringent recycling strategies for both used oil and filters to protect the environment and conserve space in landfills.

PSA System for Biogas Upgradation

Pressure swing adsoprtion, also known as PSA, is emerging as the most popular biogas upgradation technology in many parts of the world. A typical PSA system is composed of four vessels in series that are filled with adsorbent media which is capable of removing water vapor, CO2, N2 and O2 from the biogas stream.

During operation, each adsorber operates in an alternating cycle of adsorption, regeneration and pressure buildup. Dry biogas enters the system through the bottom of one of the adsorbers during the first phase of the process. When passing through the vessel, CO2, N2 and O2 are adsorbed onto the surface of the media. The gas leaving the top of the adsorber vessel contains more than 97% CH4

Biogas upgradation through PSA takes place over 4 phases: pressure build-up, adsorption, depressurization and regeneration. The pressure buildup is achieved by equilibrating pressure with a vessel that is at depressurization stage. Final pressure build up occurs by injecting raw biogas. During adsorption, CO2 and/or N2 and/or O2 are adsorbed by the media and the gas exits as CH4.

Depressurization is performed by equalizing with a second pressurizing vessel, and regeneration is achieved at atmospheric pressure, leaving a gas that contains high concentrations of CH4 to be re-circulated. During the regeneration phase, the bed must be regenerated by desorbing (or purging) the adsorbed gases. Purging is accomplished by reducing the pressure in the bed and back-flushing it with some of the concentrated gas product. The gas pressure released from one vessel is used by the other, thus reducing energy consumption and compressor capital costs.

Special adsorption materials are used as a molecular sieve, preferentially adsorbing the target gas species at high pressure. The adsorbent media is usually zeolites (crystalline polymers), carbon molecular sieves or activated carbon. Aside from their ability to discriminate between different gases, adsorbents for PSA systems are usually very porous materials chosen because of their large surface areas.

Accelerating EV Adoption: The Game-Changing Role of DC Fast Chargers

The shift towards electric vehicles (EVs) is an essential step in our journey towards a more sustainable and environmentally friendly future. With the increasing urgency to reduce carbon emissions and combat climate change, the adoption of EVs has become a critical focus globally.

The key to DC fast charging’s efficiency lies in its high power output, typically ranging from 50 kW to 350 kW, compared to just 3 kW to 19 kW for Level 1 and Level 2 chargers. This high power enables quick battery top-ups, making it ideal for highway rest stops and urban charging stations where time is of the essence. In addition, the technology behind DC fast chargers is constantly evolving, with newer models offering even higher outputs and faster charging times. This technological advancement not only improves user convenience but also enhances the overall feasibility of electric vehicles for daily use and long-distance travel.

The Impact of DC Fast Charging on EV Market Growth

The proliferation of DC fast charging infrastructure is having a profound impact on the growth of the electric vehicle (EV) market. This form of charging technology is a key factor in alleviating range anxiety, a major barrier to EV adoption. Range anxiety, the fear of running out of power before reaching a destination or a charging station, has been a significant hurdle for potential EV buyers. With the advent of DC fast chargers, this concern is greatly diminished, making EVs more appealing to a broader audience.

DC fast charging stations are becoming more widespread, not just in urban areas but also along major highways, facilitating long-distance travel. This expansion plays a crucial role in enhancing the practicality and convenience of owning an EV. The availability of quick, efficient charging solutions boosts consumer confidence in EVs as a reliable alternative to traditional combustion engine vehicles. Consequently, as the charging infrastructure continues to improve and expand, we can expect to see a corresponding rise in EV sales and a more rapid transition to electric mobility.

A thing to note when installing such systems is that you ensure that you are working with HVAC specialists so that if an issue occurs, you will be sorted within a short time. The worst thing would be having issues with your HVAC system and not having a well-informed specialist working on it.

This article will explain several reasons why installing a smart HVAC system is something you should consider for a commercial space.

Efficient Energy Management

One of the primary advantages of smart HVAC systems in commercial spaces is their ability to optimize energy consumption. Traditional HVAC systems often operate on fixed schedules and settings, leading to unnecessary energy expenditure during periods of low occupancy or when the weather conditions are moderate. Smart HVAC systems, on the other hand, leverage advanced sensors and algorithms to continuously monitor and adjust the heating and cooling requirements based on real-time data.

These systems can analyze factors such as the number of occupants, outdoor weather conditions and even the time of day to dynamically adjust the temperature and airflow. By doing so, they ensure that energy is only utilized when and where it is needed, leading to substantial energy savings. This not only translates to reduced operational costs for businesses but also aligns with the growing emphasis on sustainable practices in today’s corporate world.

Improved Comfort and Productivity

A comfortable working environment is crucial for employee productivity and well-being. Smart HVAC systems contribute significantly to achieving this goal by providing precise control over indoor climate conditions. Occupants can customize their comfort preferences through intuitive interfaces, allowing them to set individualized temperature and ventilation settings.

Moreover, smart HVAC systems can adapt to changing conditions in real-time. For instance, if a meeting room experiences a sudden influx of people, the system can quickly adjust the temperature and airflow to ensure optimal comfort. This adaptability enhances the overall satisfaction of occupants, fostering a more conducive and productive work environment.

Remote Monitoring and Control

One of the standout features of smart HVAC systems is the ability to be monitored and controlled remotely. Building managers and facility personnel can access the system through dedicated apps or web interfaces, providing real-time insights into the performance and status of the HVAC infrastructure. This remote accessibility is particularly beneficial for large commercial spaces or multi-site operations.

Remote monitoring allows for proactive maintenance and troubleshooting. System malfunctions or inefficiencies can be identified promptly, minimizing downtime and potential disruptions to business operations. Additionally, the ability to control HVAC settings remotely enables facility managers to optimize energy usage based on occupancy patterns and external weather conditions, contributing to a more streamlined and efficient operation.

Integration with Building Automation Systems

Smart HVAC systems are integral components of broader building automation systems (BAS), which are designed to enhance the overall efficiency and management of commercial buildings. Integration with BAS allows smart HVAC systems to communicate with other building systems, such as lighting, security and occupancy sensors, creating a cohesive and interconnected infrastructure.

For example, when a smart HVAC system detects low occupancy in a specific area, it can communicate with the lighting system to dim or turn off lights in that area, further conserving energy. Similarly, in the case of unexpected security events, the HVAC system can contribute to emergency response strategies by adjusting airflow patterns to isolate affected areas. This level of integration not only improves operational efficiency but also provides a holistic approach to building management.

Data-driven Insights for Decision-making

Smart HVAC systems generate a wealth of data through sensors, actuators and user interactions. This data can be harnessed to derive valuable insights that aid in making informed decisions related to energy management, maintenance schedules and system performance. Analyzing historical data allows building managers to identify patterns, optimize energy usage and plan maintenance activities more effectively.

Furthermore, data-driven insights can be utilized to assess the long-term performance of the HVAC system and make informed decisions regarding equipment upgrades or replacements. This proactive approach helps extend the lifespan of HVAC components and reduces the likelihood of unexpected breakdowns, saving both time and resources.

Conclusion

The role of smart HVAC systems in commercial spaces extends far beyond the conventional scope of heating and cooling. These intelligent systems not only enhance energy efficiency and sustainability but also contribute to the overall comfort, productivity and well-being of occupants. As technology continues to advance, the integration of smart HVAC systems with other building automation technologies will likely become even more seamless, offering a comprehensive solution for the modern commercial environment.
