We all face a variety of health risks as we go about our daily lives. Driving in cars, flying in planes, engaging in recreational activities, and exposure to environmental contaminants pose varying degrees of risk. Some risks are simply unavoidable. The good news is the air quality in your home is a risk you can do something about and can be as simple as changing air conditioning filters. 

When it comes to air pollution, there is no place like home. Today, most of the houses are well insulated and sealed to keep the weather outside, but also prevent airborne contaminants inside that cause allergies. According to the Environmental Protection Agency of the U.S., who spend up to 90 percent of our time indoors where it can be contaminated from two to five times higher, and occasionally more than 100 times higher than levels in the outdoors. 

As a result, EPA has identified indoor air pollution as one of the top five urgent environmental risks to public health. This makes the performance of your air conditioning filters more crucial than ever. The dust and dirt floating in the air and collecting on end tables and shelves is only a fraction of what is actually swimming in the air: a mixture invisible dust mites, pollen, animal dander, mold, and the smoke can be annoying breathing and dangerous to your health and cause allergic episodes. 

When the air conditioner filters are clogged due to not have changed the result of poor indoor air quality can cause or contribute to the development of chronic respiratory diseases such as asthma, bronchitis and hypersensitivity pneumonitis. May cause headaches, dry eyes, nasal congestion, nausea and fatigue. At greatest risk are people who already have respiratory diseases such as the elderly and children.

 

If you live in an area of ​​the country with extremely hot temperatures, you are probably relying on your air conditioner or heat pump throughout the year. People in places like Arizona, Nevada, California and Hawaii to name a few, will probably not know what to do with them without some sort of cooling system in their homes. Only one question remains: what kind of system you should buy?

To make the best decision for your home, you should compare the heat pump and central air conditioning systems. You can then make an informed decision as to what would be best for your particular home and surrounding climate. The Arizona heat pumps operate as a heating and cooling system. When a heat pump cools a house, it takes heat from the air inside the house and pumps it outside. For heat pump collects heat from the air, water or ground out and moves inside. Basically moves heat from one place to another.

An air conditioner is completely equal a heat pump. Air conditioners make your own cold air by evaporation of Freon or other refrigerant. There are both inside and outside coils central air. The unit has a compressor to change the Freon gas into hot gas, high pressure that travels through the coils. When this is done, loses heat and becomes liquid. The liquid gas is evaporated in a cold, low pressure. As the gas enters the coils absorbs heat and reduces inner temperature.

Heat pumps are today's more efficient heating systems as heating a house in winter and cools it in summer. This is a major reason why people generally installing them in the home and workplace. It is easy to operate and effective in doing its job. It uses electricity as an energy source. It is known for its energy efficiency operation. Just for a mere flip of a switch homeowners can reverse the role of a heat pump is used for heating to cooling. Can be installed in any building and is therefore considered one of the most sought after heating start. 

Maintenance of the indoor unit of a heat pump consisting mainly of cleaning air filters. To do this, you should have to remove the panel of the indoor unit. Pay attention to unscrew all the screws and place them somewhere you will not lose them. Behind the panel, you get through the first two filters is mesh type and the other is a child with fine pores. Remove both the filters to see any accumulation of dirt and grime and clean with a suitable cleaning agent (diluted vinegar recommended). Dry and replace. Reinstall the panel and filter cleaning is done. 

Dirty filters are the leading cause of equipment failure, such as clogged air filter restricts airflow through the system. Over time, this can lead to an engine burning a superheated system, or complete system failure. Replace filters regularly is the best way to prevent this from happening.

If you have plans to invest in a heating and cooling, learning efficiency of the heat pump should be of interest to you. In these days where money is a little hard to find and the best way to avoid that when you really have to buy something smart. By investing wisely, the number of benefits that will outweigh the disadvantages unexpected item you are considering buying.

Measuring the efficiency of the heat pump is not as complicated as you might think. With the use of some standard measures currently known, determine and evaluate how well run the unit can be revealed immediately.

Four known patterns can be used as follows: coefficient of performance (COP), Energy Efficiency Ratio (EER) and heating seasonal performance factor (HSPF) and seasonal energy efficiency ratio (SEER). The coefficient of performance is the most common type of measurement used to assess the performance of the unit. What is a bit tricky on the interpretation of this value is immediately affected when there is a sudden drop in air temperature outside the house.

Because of the mild winters of a city, residents who live in a temperate climate zone do not need high power furnaces in their homes. Instead, they can heat their homes with heat pumps, devices that provide heating in winter by transferring heat inside, and summer cooling by transferring heat from outside. The implementation of a heat pump instead of a furnace and air conditioner can produce significant savings in air conditioning. The advantages of the application of a pump does not stop there but also include:

Because they use less energy than conventional ovens and air conditioners, heat pumps are one of the eco-friendly solutions available HVAC. To choose a heat pump that provides the best energy efficiency, choose one that has a high seasonal energy efficiency ratio (SEER) classification for cooling and overheating Seasonal Performance Factor (HSPF) for heating Classification.

 

Homeowners and HVAC technicians use heat loss calculations to determine the size of the heating system needed to maintain comfortable indoor environment using less energy. In order to calculate the heat loss or gain of a particular house. This complicated mathematical process takes into account all the factors that can affect the heating in a house.

Calculate the design temperature (DT) for the house, using the formula DT = IT – OT. The design temperature takes into account their preference for the internal temperature (IT) and the average outside temperature (OT) for their region. For example, if OT TI = 75 = 65, the home DT is 10. Get a copy of your house plans clearly marked dimensions for walls, windows, doors and ceilings. Use a tape measure to determine the dimensions not covered by housing plans.

The formula for surface area is SA = height x width. It may be helpful to label each door and window in the house plans and create a separate list. Write the area of ​​each window next to the label for quick reference in subsequent calculations. Calculate the surface area (SA) of an exterior wall of the house. Calculating the surface area of ​​an exterior wall surface area subtracting doors or windows on that wall. The formula for the surface area of ​​an exterior wall is SA (wall) = (height x width) – SA (gate) – SA (window). If more than one window or door, subtracting the surface area of ​​each window or door in the wall. Repeat the calculation of the surface area of ​​each exterior wall of the house.

Calculate the value U (UV) to the walls, doors, windows and roof of the house. U value is typical heat loss of a particular surface in the home. The formula for the value U is UV = 1 / R-value, where the value R is the potential of a surface insulation. If you do not know the R-value of windows, doors or insulation in your home, see Resources for a list of typical R-values. Calculate the surface heat loss (SHL) using the formula SHL = U xx SA DT value. Calculate the heat loss from the surface of each wall, window, door and ceiling. Add the surface heat loss for each wall, windows, doors and roof. This equals the total heat loss for the home.

 

R410A is certainly more environmentally friendly than R-22, because it does not emit hydrofluorocarbons as R-22 does. R410A therefore does not damage the ozone layer. But this is not the only advantage. R410A refrigerant is actually better for several reasons. First, R410A transfers heat in either direction (absorbing and releasing) more easily than R22, which makes a more efficient cooling. This means that the unit can operate at cooler temperatures, keeping the air cooling capability. This reduces substantially the risk of overheating and extends the life of your unit.

In addition, the lubricant used with R410A is synthetic, designed to mix better than those used with R22. This means that the coolant flows more easily, also results in less wear. R410A operates at higher pressures than R22. An interesting side effect is that, since they are thicker.
