Refrigeration Principles Quiz

The evaporation process contributes to the cooling effect in a refrigeration system by absorbing heat from the surroundings as the refrigerant evaporates, thus lowering the temperature.

The role of the expansion valve in a refrigeration system is to regulate the flow of refrigerant into the evaporator, causing a pressure drop and allowing the refrigerant to expand, which leads to a drop in temperature.

The purpose of a condenser in a refrigeration system is to remove heat from the refrigerant, causing it to condense from a vapor to a liquid, which allows it to release heat to the surroundings.
