Glossary of Terms
- Refrigeration cycle
- Vapor compression cycle used in air conditioning, heat pump, and refrigeration systems.
- Heat pump
- Device which pumps heat from a low temperature energy source to a higher temperature energy sink, generally for space heating or domestic water heating. Also called “reverse cycle air conditioner.”
- Dedicated heat pump
- One that operates in one cycle only; also called “one-way” heat pump.
- Condensing unit
- Compressor-condenser package used for split systems with separate evaporator.
- Condenser
- Device used in an air conditioning, heat pump, or refrigeration system to convert high pressure refrigerant vapor to liquid while heating a fluid, generally water, glycol, or air.
- Evaporator
- Device used in an air conditioning, heat pump, or refrigeration system to convert a low pressure mixture or refrigerant vapor and liquid to pure vapor while cooling (chilling) a fluid, generally water, glycol, or air.
- Subcooling
- Condition where liquid temperature is lower than the saturated liquid temperature corresponding to the liquid pressure.
- Superheat
- Condition where vapor temperature is higher than the saturated vapor temperature corresponding to the vapor pressure.
- Heat of compression
- Heat added to refrigerant during work of compression, i.e., the heat equivalent of compressor work.
- Saturated condensing temperature
- Saturated refrigerant vapor temperature corresponding to condenser inlet pressure, normally measured at compressor discharge.
- Saturated suction temperature
- Saturated refrigerant vapor temperature corresponding to pressure at compressor inlet (suction).
