What Do UV Lights Really Do For Your Indoor Air Quality

Indoor air pollution is a growing concern for many. In fact, the EPA (Environmental Protection Agency) states that indoor air pollution can be worse than outdoor air pollution. Different forms of airborne germs, bacteria, fungi, mold and mildew are on the increase in indoor environments. These substances all affect the health of household residents and cause a number of health problems. Those with asthma or allergies are more prone to breathing difficulties. Using UV (ultraviolet) light is an effective method for purifying and cleaning the air.

Why is Indoor Pollution Increasing?

The spread of germs, mold and other pollutant inside the home is due to a number of factors. One is how homes are now insulated. Many people keep windows closed for most of the year and this keep the same pollutants circulating throughout the house. Another factor is the airflow in a home. Even the ductwork or drain pans of the HVAC (heating, ventilation, air conditioning) system are a source for the growth of these pollutants. Not cleaning the filters of the furnace or air conditioning system also contributes to poor indoor air quality.

How UV Light Help to Clean Indoor Air

The UV light creates ultraviolet radiation which destroys indoor air pollutants by turning them into harmless substances. Another method for cleaning the indoor air is using germicidal UV lights. Ultraviolet Germicidal Irradiation (UVGI) is a method that uses short UV waves to destroy bacteria, viruses, allergens and pollutants. Also known as UVC, these lights work by breaking down the DNA of mold, bacteria, viruses, mildew, spores and other harmful microorganisms that pollute the air.

The best way to get the UV light is with UV lamps. You can use the UV lamps in a variety of ways. You can use UV lamps in the ductwork of your HVAC system or in the HVAC filtration system. Another method is to shine the UV light on the heat pump of evaporator coils or on air conditioners directly.

Airborne pathogens reduce indoor air quality and increase health risks. You can get cleaner air in your home by using UV lights. Using the lights on an ongoing basis gives you healthier and more breathable air.

Commercial HVAC Systems—What You Need To Know

Most business owners know that commercial HVAC systems installed in their premises add heavily to their monthly overhead. However, for the purposes of employee comfort and having a productive work environment, there is no getting away from having all those heating and cooling systems around your place. However, there are ways and measures that you can take which will help cut down on the energy consumption by your HVAC systems. Here are a few things that you can do towards that goal.

First of all, never oversize your HVAC equipment. Have a HVAC professional check your cooling or heating requirements and advise you on proper sizing. If you want to go on your own, the ACCA Manual N is designed for HVAC systems at commercial facilities. Use that as a guide to ensure proper sizing of your equipment.

If you are buying light commercial HVAC units or room air conditioners, make sure to go for ENERGY STAR rated models. You may also want to check the differences in lifecycle costs between high-efficiency and standard-efficiency units. If the high-efficiency units come with less lifecycle costs, invest on them, even if it means paying a somewhat steep price upfront.

If you have garages or warehouses at your facility, consider using radiant heating in place of traditional HVAC units. Radiant heating does not heat the air but the objects and consumes less fuel in the process. You may also consider using radiant heat for waiting areas, patios and other exterior premises.

Another good idea is to use demand controlled ventilation system and economizers. Economizers attracts the fresh air from outside when the temperature outside is lower than that of the indoors. You may also consider using supplemental dehumidifiers which help to bring down the humidity level in the inside atmosphere and make for greater comfort, thereby reducing the load on your cooling system.

If your facility is located in colder climates, consider making good use of heat recovery methods. For example, heat generated by processes such as cooking, etc. can be captured and this can reduce cooling and heating costs of the facility.

Fans Or A/C – Which Is Better?

Better is a highly subjective work. It denotes comparison between two opposing objects with given a set of criteria. The debate as to whether fans or A/C is better has been around for a long while and the answer is not always conclusive. It depends on which things you value the most as both have their own strengths and weaknesses as we shall see below.

Electric Fans

Fans have blades that turn rapidly when current passes through the motor. The result is increased circulation as the movement forces air from one side to another. Strictly speaking, fans do not lower the temperature inside a room. However, the increased air flow can result in evaporative cooling as the wind hits the skin. People need to be fairly near the fan to experience this cooling effect as it tapers off with greater distance. These appliances are cheap and they use less power compared to ACs so they are relatively inexpensive to operate.

Air Conditioners

ACs on the other hand, can take on many forms. The most basic window type air conditioner is a box that contains a compressor, a condenser, condensing coils, evaporating coils, and many other parts. It works through heat transfer whereby the heat inside a room is pushed into the outside so that the air feels colder. Given an adequately sized unit, a person can feel cooler no matter where he is inside the room. Aside from the cooling effect, AC systems also lessen humidity and enhance air quality. They consume a considerably larger amount of energy when in operation.

The Verdict

If budget is the number one priority, then using fans is a better choice since the units themselves are inexpensive and the utility bills will not shoot up drastically despite whole day use. Of course, they may not provide the most comfortable environment during the peak of summer but that is a trade-off people have to live with. If comfort is the main concern, then A/Cs win hands down. They can keep the home cool no matter how terrible the heat outside gets. For lower energy consumption, get a highly efficient model.

Ways To Increase Your Air Conditioner’s Efficiency

The Department of Energy reports that heating and cooling bills are take a large percentage of the utility expenses of most households and commercial buildings. According to the Department, the central air conditioning system is the major source of expenditure in the average US home.

You can take proactive steps to reduce the energy consumed at home. As the weather gets warmer, the following tips can help to improve the air conditioning in your home without increasing your bills.

1. Clean the Outdoor Condenser Unit
To improve the air conditioning efficiency, have the debris thoroughly cleaned from your unit. Debris in the system can make heat to be expended without being used. Contact an HVAC systems professional for in-depth and thorough cleaning.

2. Keep the vacuum indoor vents unblocked
Maintain steady airflow in your conditioning system for optimum energy emission. To achieve this, vacuum any debris or dirt from the indoor supply vents. Also, keep things like toys, furniture and blinds from blocking the vents.

3. Regulate the thermostat
Adjusting the temperature to 5-8 degrees (up in summer and down during winter) can help save energy and money. A programmable thermostat can automatically adjust temperatures to a suitable level at different times of the day or when you are away from home.

4. Keep the blinds and curtains closed
You can easily store some heat inside the house by keeping the blinds and curtains closed when the sun is directly hitting the windows. This will help you cut costs of your air conditioning system.

5. Keep heat appliances away from the thermostat
When heating appliances are placed near the thermostat, the temperature can be automatically adjusted based on the the appliances. Keep the appliances away from the thermostat or else the system will work harder, use more energy and run longer than needed.

6. Ensure your drain line is clear
Most drain lines are built next to the indoor cooling coils mounted directly above the basement furnace. Flushing a cup of chlorine bleach down the air conditioning drain and then rinsing it with a gallon of water will keep the drain clear during summer.
