Saving Money With Air Source Heat Pumps
Many homes and businesses have found the use of air source heat pumps (ASHP) the answer for having a good cooling and warming system in their location. It absorbs warmth from the outside air and releases it indoors for comfortable surroundings. It is also built to provide air conditioning.
This device works on the principle that any outside air above zero contains some heat, which the ASHP pumps for the purpose of space warming or providing hot water. They are considered one of the least expensive ways of providing warm and/or cool air for domestic use.
There are two principle parts to the pump. They are the indoor and outdoor heat exchanger coils. The outdoor coil is used to extract warmth from the outside air and the indoor coil moves it to an indoor water tank or other arrangement.
Heat transferring is a principle used by many different kinds of pumps. The terms used are "heat source" and "heat sink". Source refers to temperature collected from the air or from the ground. Sink refers to where the warmth ends up, such as at a home or business.
The air-source pump is the most popular among the many different models and systems on the market. It is unique in that refrigerant-filled coils are used, together with two fans, a compressor, and a reversing valve. Outside air is pumped through the coils to produce the warm or cool air desired.
The reversing valve allows the unit to produce either hot or cold air by reversing the flow of the refrigerant. In other words, instead of bringing heat into the house, it can release it. By using an outdoor fan, air is pulled over refrigerant-filled coils and blown away from the coils by the inside fan. In commercial establishments, this system is usually housed in a box on the roof with ductwork installed through the wall.
Two interesting types currently on the market are absorption and ground-source pumps. Their principle of operations is unlike that of the ASHP. With ground-source, it is the underground temperature that is utilized via a closed or open loop system. It comes from an underground water source or from the ground itself.
For Absorption pumps, the power comes from natural gas, geothermal-hot water, solar power, or propane. For many years, this was used only by large commercial enterprises but now is available for large houses. Its principle is to absorb ammonia in water, which is pressurized to a boil providing continuous warmth.
Manufacturers are required to rate air source heat pumps for coefficient of performance (COP). When checking out a system for your situation always look at models that show a COP of more than 0.7 for cooling and a 1.2 for warming. Using one of these units is a good way to save from 30 to 40 percent on utility bills. There is a huge amount of information easily accessible on the Internet regarding these warming/cooling units and how they can control the temperature of any home or business area.
