Equal to its latent heat of vaporization. Less than its latent heat of vaporization.

Greater than its latent heat of vaporization. The refrigerating effect of a refrigerant is:Įqual to its latent heat of vaporization. The ideal refrigerant should:īe easily detected because of its strong odour. Are well suited for industrial refrigeration. Ammonia refrigerants:Īre well suited for industrial refrigeration.Īre ideally suited to copper piping system. Latent heat of vaporization minus the heat required to flash the liquid due to the pressure drop. Latent heat of vaporization plus the heat required to flash the liquid due to the pressure drop. is:īoiling point Density The amount of heat absorbed by a refrigerant in the evaporator is equal to its: Miscibility Corrosiveness The property which has to be known for the calculation of the size of control valves and piping etc. hich of the following is not a physical property of refrigerants: The condensing temperature of the refrigerant vapour is 15°-20☌ higher than the temperature of the cooling medium. The refrigerant absorbs latent heat of condensation from the cooling medium. The condenser transfers latent heat from the cooling medium and adds it as sensible heat to the refrigerant. The condensing temperature of the refrigerant will be lower if the pressure of the refrigerant is increased. In the condenser, heat transfers from the cooling medium to the refrigerant. Absorbed by the refrigerant in the evaporator With regard to the condenser in a refrigeration system, which of the following statements is true? The net refrigerating effect of a refrigerant is the amount of heat:Ībsorbed by the refrigerant in the evaporator.Ībsorbed by the refrigerant in the condenser.ĭischarged by the refrigerant in the evaporator.Ībsorbed by the evaporator. In a closed vessel, the boiling point of a liquid can be raised by:
