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.
Using the principle that all outside air that registers above zero contains some heat, the ASHP uses it for both providing hot water and warming up interior spaces. For domestic use these systems are considered the cheapest way of providing warmth and cooling in a home or business.
Indoor and Outdoor Exchanger coils are the two main parts of the pump. Each has a special task to perform. Heat is extracted from the outdoor air by the outdoor coil. This is then moved to a distributing arrangement or an indoor water tank.
Temperature transfer is the basic principle on which the many different kinds of pumps operate. In simple terms, warmth from the air or ground is considered a "heat source", and pumped into your home or other location, which is called the "heat sink".
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.
Also included are ground-source and absorption pumps, among others. These operate on different principles than the ASHP. The ground-source type utilizes a hot underground temperature, which comes from the ground itself or underground water. This is transferred indoors via a closed loop or open loop systems.
Natural gas, geothermal-heated water, solar power, or propane-heated water is what powers the Absorption pumps. Previously confined to large-scale operations it can now be used by large homes. Rather than using refrigerant compression, it absorbs ammonia in water and a hot source to provide a continuous source of heat.
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.
