Mechanical Engineering :: Refrigeration and Air Conditioning
- The optimum effective temperature for human comfort is
- In a refrigeration cycle, the flow of refrigerant is controlled by
- Vapour compression refrigeration is somewhat like
- At lower temperatures and pressures, the latent heat of vaporisation of a refrigerant
- A refrigeration cycle operates between condenser temperature of + 27°C and evaporator temperature of -23°C. The Carnot coefficient of performance of cycle will be
- The bypass factor (B. P. F.) in case of sensible heating of air is (Where td₁ = Dry bulb temperature of air entering the heating coil, td₂ = Dry bulb temperature of air leaving the heating coil, and td₃ = Dry bulb temperature of heating coil)
- The general rule for rating refrigeration systems (excepting for CO₂ system) is to approximate following h.p. per ton of refrigeration
- The coefficient of performance (C.O.P.) of a refrigerator working as a heat pump is given by
