Study Notes
Basic Refrigeration Cycle
- A refrigeration cycle, also known as a heat pump cycle, moves heat away from a desired area.
- This is achieved by manipulating the pressure of a refrigerant (like air, water or synthetic refrigerants).
- The cycle involves compression and expansion.
Major Components
- Compressor: Increases pressure of the refrigerant, concentrating the heat it contains. Changes low-pressure gas to high-pressure gas.
- Condenser: Removes heat from hot refrigerant vapor until it condenses into a saturated liquid. The refrigerant is then a high-pressure, low-temperature liquid.
- Expansion Valve: Reduces pressure from the liquid refrigerant, allowing it to expand and change state from liquid to vapor in the evaporator.
- Evaporator: Cools the refrigerant to absorb heat. A fan cools the system, converting refrigerant to a vaporous state.
Cycle Summary
- Compressor: Pressure increaser
- Condenser: Heat rejector
- Expansion valve: Pressure dropper
- Evaporator: Heat absorber
