Question

A valve that controls refrigerant flow as it monitors and responds to temperature in an evaporator is typically known as a:

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

Answer 1

The valve known for controlling refrigerant flow and responding to the evaporator temperature is the Expansion valve. It is part of the heat pump or air conditioning system that assists in cooling the refrigerant as it returns to the evaporator coils.

Step-by-step explanation:

The valve that controls refrigerant flow while monitoring and responding to temperature in an evaporator is typically known as a Expansion valve. In the cycle of a heat pump or air conditioning system, the evaporator plays a crucial role in absorbing heat from the environment to turn the refrigerant from liquid to gas, which is then compressed, raising its temperature and pressure. The refrigerant passes into the condenser, where it gives off heat to the surroundings and turns back into a liquid. Finally, it returns to the evaporator through a pressure-reducing valve, which is the expansion valve, where it cools down by expanding, resuming the cycle.
