In the vapor-compression refrigeration cycle, it is the refrigerant that circulates through the equipment, transporting heat from the cooled (or refrigerated) space to an outside fluid (air or water). The transfer of heat to and from the refrigerant is accomplished by the refrigerant changing phase from liquid to gas and from gas to liquid. The refrigerant used in a system must be able to evaporate at a temperature below the desired temperature in the refrigerated space, and condense at a temperature above the temperature of the outside fluid.

The following key questions are answered in this module:
Does "evaporation" occur on the low pressure side or high pressure side of the refrigeration cycle? The low pressure evaporator side is where the refrigerant evaporates from a liquid to a gas.
Does "condensation" occur on the low pressure side or high pressure side of the refrigeration cycle? The high pressure condenser side is where the refrigerant condenses from a gas to a liquid.
What is a vapor pressure curve? It is a curve that shows the relationship between pressure and boiling point temperature for a particular substance.
What should you consider when selecting a refrigerant? The pressures in the system, desired temperature in the refrigerated space, and temperature range of the outside fluid (air or water) must all be considered.
Why is it desirable for the refrigerant in the line going to the compressor to contain some superheat? This prevents liquid refrigerant from reaching the compressor, which can damage it, and it also increases the total amount of heat removed from the refrigerated space.
