Question:-
Which one of the following is responsible for the operation of a thermostatic expansion value?
Option (A)
Pressure changes in evaporator
Option (B)
Temperature changes in evaporator
Option(C)
Degree of superheat in evaporator
Option(D)
Degree of sub cooling in evaporator
Correct Option:
(C)
Question Solution:
Thermostatic expansion value is also called a constant superheat value because it maintain a constant superheat of the vapour refrigerant at the end of the evaporator coil by controlling the flow of liquid refrigerant through the evaporator.
