An undesirable property of a refrigerant is its:
रेफ्रिजरेंट का एक अवांछनीय गुण है:
Low freezing
point
High
miscibility with lubricating oil
Low viscosity
Low latent heat of evaporation
Low latent heat of evaporation
An
undesirable property of a refrigerant is its low latent heat of evaporation. A
refrigerant must have low specific heat and high latent heat because high
latent heat at low temperature increases the refrigerating effect per kg of
refrigerant.
Hence, the
correct option is (D).
