| Split System |
Split heat pumps are two (2) part refrigeration systems which have separate evaporator / air handler and compressor / condenser sections. Commonly employed in air-to-air systems where the condenser section is located outside the home while the evaporator / air handler is located inside the conditioned structure. |
| Temp. diff. |
Difference between ELT and a LLT. |
| Ton (of refrigeration) |
The amount of energy it takes to convert 2000 lbs. of water at 32º F. to ice at 32º F. during a 24 hour period. Calculation: 2000 lbs.H2O x 144 Btu/lb. = 288,000 Btu's in 24 Hrs. Divide by 24 hrs = 12,000 Btu/hr. Therefore a "ton" of cooling is a measure of heat energy which is roughly equivalent to 12,000 BTU's. |
| Turbotec® |
Tradename for a high efficiency expanded surface style coaxial tube-in-tube heat exchanger. |
| TX Valve |
A temperature and pressure controlled device for metering refrigerant in a heat pump or other refrigeration device. |
| Water Well |
A vertical bore hole into the earths crust usually to a depth of less than 300 ft. for the purpose of accessing an underground water supply (aquifer). A pumping system generally of the submersible type is normally installed to bring the water to the surface under sufficient pressure to be used in a home. |
| Water-to-Water |
A heat pump which extracts heat from water in one area and transfers the heat usually at a higher temperature to another body of water. ex. extracting heat from a 50°F. well and using it to heat domestic hot water at 120° F. |
