Question

Which of the following cools the air in a household refrigerator?

A. Reduction of the air temperature due to condensation of the gaseous refrigerant
B. Absorption of the heat from the air due to evaporation of the liquid refrigerant
C. The transfer of heat to the evaporator due to compression of the liquid refrigerant
D. The transfer of heat from the air to the compressor due to expansion of the gaseous refrigerant

Answer 1

B.Absorption of the heat from the air due to evaporation of the liquid refrigerant

Answer 2

The following cools the air in a household refrigerator: Absorption of the heat from the air due to evaporation of the liquid refrigerant . Correct answer:B

The function of the refrigerator is to absorb heat into the refrigeration system. The evaporator is placed in the area to be cooled. The refrigerant vaporizes from the heat it absorbs heat in the evaporator.
