Question

Refrigerant vapor picks up additional heat as it flows from the evaporator to the compressor; the heat is picked up from the

A) Condenser
B) Expansion valve
C) Refrigeration cycle
D) Evaporator

Answer 1

The correct option is (D). Evaporator; The refrigerant vapor gains additional heat from the evaporator as it heads toward the compressor in the refrigeration cycle, due to heat absorption from the environment.

Step-by-step explanation:

The refrigerant vapor picks up additional heat as it flows from the evaporator to the compressor in a refrigeration cycle. This occurs because the evaporator is the component where the refrigerant absorbs heat from the surrounding environment, causing it to vaporize. Here's the basic flow in a refrigeration cycle:

• The low-pressure, cool refrigerant vapor from the evaporator is drawn into the compressor.
• In the compressor, the refrigerant vapor is compressed, which increases its temperature and pressure.
• The high-temperature, high-pressure vapor then flows into the condenser, where it releases heat to the surroundings and condenses into a liquid form.
• The high-pressure liquid refrigerant is then passed through an expansion valve, reducing its pressure and initiating the process of cooling as it heads back into the evaporator.

The additional heat pickup mentioned in the question refers to the process within the evaporator, not the condenser, expansion valve, or refrigeration cycle in general.
