| Term | Definition |
|---|---|
| Desuperheater |
A heat exchanger and pump system which removes a small portion of heat from the compressor discharge gas and typically transfers it to a domestic hot water tank. |
| Dual Condenser |
A heat pump system which has the capability to switch, usually automatically, between an air and a water heat exchanger. Full capacity hot air or hot water output is available. |
| EAT |
Entering air temperature. |
| EER |
Energy efficiency ratio. |
| ELT |
Entering liquid temperature. |
| Energy Efficiency Ratio (EER) |
Cooling capacity in BTU/hr divided by electrical energy consumed in watts. |
| Evap. T. |
The temperature on evaporator side when Freon is converted from a liquid to a vapor (gas). |
| Evaporator |
The heat absorbing mechanism or heat exchanger in a heat pump. Refrigerant changes phase from a liquid to a gas in this exchanger, absorbing heat energy from the surrounding media in the process. |
| EWT |
Entering water or fluid temperature. |
| Fan-Watts |
Blower motor electricity consumption. |
| Flow IGPM |
Liquid flow. |
| Freon |
Trade name for a series of man made chemicals or refrigerants used in refrigeration systems. Each refrigerant is designed to change phase at specific temperatures and pressures which will produce the desired cooling effect required for a specific job. The refrigerant absorbs energy as it evaporates and releases energy during condensation. |
| Full Package |
Self contained heat pump which has blower and compressor section integrated into one unit. |
| Full-Condensing Heat Exchanger |
A heat exchanger with enough surface area to condense all the hot refrigerant gas produced by a heat pump to it's liquid state thereby transferring the all the heat produced by the unit. |
| Geothermal Energy |
Heat energy stored in the earth's crust by the absorption of solar energy and by conduction with the earth's hot interior. |
