Chapter 6 – Cooling Production Refrigeration Cycles

These flashcards cover fundamental concepts, terms, and processes related to refrigeration cycles and cooling systems as discussed in Chapter 6.

Refrigeration

The process used to produce cooling by moving heat from low-temperature sources to high-temperature destinations.

Vapor Compression Cycle

A refrigeration process using a refrigerant that vaporizes and condenses to absorb and reject heat.

Refrigerant

A fluid with suitable properties for vaporizing and condensing in refrigeration systems.

Evaporator

A device in the refrigeration cycle that absorbs heat from the environment.

Condenser

A device that rejects heat during the refrigeration cycle.

Compressor

The component that circulates the refrigerant through the refrigeration cycle.

Latent Heat of Vaporization

The heat absorbed by a refrigerant when it changes from liquid to gas.

Latent Heat of Condensation

The heat released by a refrigerant when it changes from gas to liquid.

CFC

Chlorofluorocarbons, a group of refrigerants that were phased out due to their harmful effects on the ozone layer.

R-22

A refrigerant that was popular globally but phased out due to its ozone depletion potential.

Direct Expansion (DX) Systems

Systems that use refrigerant in the air-conditioning coils to cool air directly.

Chilled Water Systems

Cooling systems that produce chilled water centrally and distribute it to air-conditioning units.

Cooling Tower

A structure that produces water at appropriate temperatures for condensing by evaporative cooling.

Gravity Draft

A cooling tower air flow concept that relies on natural convection.

Induced Draft

A cooling tower air flow concept where fans draw air through the tower.

Forced Draft

A cooling tower air flow concept where fans push air into the tower.
