Refrigerant properties:
1. low boiling point & low freezing point.
2.low specific heat and high latent heat (for higher refrigerating effect per kg of refrigerant)
3. working pressures must be optimum(cost & ingress of air)
4.high critical pressure and critical temperature(power requirements)
5.low specific volume
6.higher thermal conductivity (reduce the area evaporator and condensor)
7. non[explosive,corrosive,toxic,flammable]
8. High miscibility and low reactivity with lub oil.
9. High co-efficient of performance.
10. economic& Eco-friendly
