Chemical Engineering Thermodynamics

An ideal liquid refrigerant should

  • A. Not have a subatmospheric vapour pressure at the temperature in the refrigerator coils
  • B. Not have unduly high vapour pressure at the condenser temperature
  • C. Both A and B
  • D. Have low specific heat
Answer: Option C.

The given are opposite to the requirements of an ideal liquid refrigerants.
The ideal liquid refrigerant should have a sub atmospheric vapor pressure at the temperature in refrigerator coils and also should have high vapor pressure at the condenser temperature.
