Mechanical Engineering :: Refrigeration and Air Conditioning
- The sensible heat factor during the heating and humidification process is given by (where h₁ = Enthalpy of air entering the heating coil, h₂ = Enthalpy of air leaving the heating coil, and hA = Enthalpy of air at the end of humidification process)
- 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)
- In chemical dehumidification process,
- The specific humidity during heating and humidification process.
- For evaporators and condensers, for the given conditions, the logarithmic mean temperature difference (tm) for parallel flow is ________ that for counter flow.
- A certain refrigerating system has a normal operating suction pressure of 10 kg/cm gauge and condensing pressure of about 67 kg/cm. The refrigerant used is
- Reducing suction pressure in refrigeration cycle
- The sub-cooling in a refrigeration cycle
- The superheating in a refrigeration cycle
- Under cooling in a refrigeration cycle
