The efficiency of an air conditioner or heat pump can even be affected by the furnace or fan coil it relies on inside the home to move air. Products that fall into the “Select sizes ENERGY STAR® qualified” category include within their model group some non-qualified units due to either size or potential installation factors. The coils can be buried vertically or horizontally underneath your property and are connected to the heat pump systems in the house. This ground coil may also be placed in the bottom of a lake or a pond. The coil or also known as the loop is usually made of highly durable high-density polyethylene plastic material. Closed loop systems refer to a geothermal heat pump system that only uses the contained fluid within the heat pump to extract heat from the ground. Open loop systems use water within a well as a running fluid. While there is only one type of open loop system, there are three types of closed loop systems.

The reversing valvecontrols the direction of flow of the refrigerant in the heat pump and changes the heat pump from heating to cooling mode or vice versa. A coil is a loop, or loops, of tubing where heat transfer takes place. The tubing may have fins to.

Heat pumps are systems that draw heat from onesource (earth, water, air or ambient) and transfer it to another. Buried pipes allow the mechanical equipment to exchange heat with the earth. During the summer, a ground-source heat pump rejects heat to the earth through the underground pipes. During the winter, the refrigeration cycle is reversed and heat is collected from the underground pipes. The primary advantage of groundsource heat pumps is increased.

GCHPs are further subdivided according to ground heat exchanger design: vertical, horizontal or slinky coil. In the present study, a simplified model is proposed to model the heat transfer from the underground buried horizontal heat exchanger pipes. A fan coil consists of a small fan and a coil. A water-source heat pump usually consists of a fan, a finned coil to condition the air, and a water coil to reject heat to a water loop during cooling, or to extract heat from the same water loop during heating. Single or multiple fan coils are always used to serve a single conditioned room.
