-
The sensible heat factor during cooling and dehumidification process is given by (where h1 = Enthalpy of air entering the cooling coil, h2 = Enthalpy of air leaving the cooling coil, and hA = Enthalpy of air at the end of dehumidification process)

Thermal diffusivity is a
-
The condition of refrigerant after leaving the compressor and before entering the condenser is superheated vapour.
-
The total radiation from a black body per second per unit area is __________ fourth power of the absolute temperature. This statement is known as Stefan-Boltzmann law.
-
In a psychrometric process, the sensible heat added is 30 kJ/s and the latent heat added is 20 kJ/s. The sensible heat factor for the process will be
-
The amount of radiation mainly depends upon the

For ammonia refrigerating systems, the tubes of a shell and tube condenser are made of
