What will the effect be if insufficient liquid refrigerant is admitted to the evaporator by a thermostatic expansion valve?
a. Insufficient force will be generated against the diaphragm and spring to open the expansion valve
b. The heat in the vapour leaving the evaporator causes the pressure in the thermal element to increase opening the expansion valve
c. The room temperature will decrease closing the expansion valve
d. The thermal element reaches an equilibrium leaving the expansion valve in the same position
e. The expansion valve will fail to respond
Answer: B
