Key Terms

Refrigeration
The process of removing heat from a designated area to lower its temperature.

Example: Refrigerators use refrigeration to keep food fresh.

Efficiency
The ratio of useful output to total input, often expressed as a percentage.

Example: An efficient air conditioner uses less energy to cool a room.

Cooling Capacity
The amount of heat a refrigeration system can remove from a space in a given time.

Example: A cooling capacity of 5,000 BTU means the system can remove 5,000 BTUs of heat per hour.

Work Input
The energy required to operate a refrigeration system.

Example: The work input for a refrigerator includes the electricity it consumes.

Heat Pump
A device that transfers heat energy from a source to a sink, often used for heating and cooling.

Example: Heat pumps can be used for both heating in winter and cooling in summer.

Thermodynamics
The branch of physics that deals with heat and temperature and their relation to energy and work.

Example: Thermodynamics principles are essential in understanding refrigeration cycles.
