Question

A valve used to direct liquid refrigerant from the liquid line to combine with hot gas and provide acooler refrigerant mixture into the low side is a:

A) Expansion valve
B) Pressure relief valve
C) Reversing valve
D) Solenoid valve

Answer 1

The valve used to direct liquid refrigerant from the liquid line to combine with hot gas and provide a cooler refrigerant mixture into the low side is the Expansion valve (option A).

Step-by-step explanation:

The valve used to direct liquid refrigerant from the liquid line to combine with hot gas and provide a cooler refrigerant mixture into the low side is the Expansion valve (option A).

The expansion valve is responsible for regulating the flow of refrigerant and reducing its pressure as it enters the evaporator coils. This pressure reduction causes the refrigerant to expand and absorb heat from the surroundings, cooling the air inside the system.

For example, in an air conditioner, the liquid refrigerant passes through the expansion valve and changes into a low pressure and low-temperature mixture of liquid and gas. This mixture then enters the evaporator coils, where it absorbs heat from the air and cools it down before being cycled back to the compressor for further cooling.
