The undesirable property of a refrigerant is
A. Non-toxic
B. Non-flammable
C. Non-explosive
D. High boiling point
The desirable property of a refrigerant is
A. Low boiling point

C. High latent heat of vaporisation
D. All of these
Between condenser and expansion valve
It's wrong answer correct answer is A
Condensor and expansion valve
Condenser and expansion valve is the right answer
Between condenser and evaporator.
A is the right ans... D is a vapour
Option (A) is correct.
Refrigerants between Expansion Valve and Evaporator is becomes Wet saturated vapor.
Condenser and expansion valve
Wrong answer
