Refrigeration and Air Conditioning 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) (hA - h2)/ (h1 - h2) (h1 - h2)/ (hA - h2) (h2 - hA)/ (h1 - h2) (hA - h1)/ (h2 - h1) (hA - h2)/ (h1 - h2) (h1 - h2)/ (hA - h2) (h2 - hA)/ (h1 - h2) (hA - h1)/ (h2 - h1) ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning For proper refrigeration in a cabinet, if the temperature and vapour pressure difference between cabinet and atmosphere is high, then Refrigerant with lower evaporation temperature should be used Perfectly tight vapour seal should be used Smaller cabinet should be used Bigger cabinet should be used Refrigerant with lower evaporation temperature should be used Perfectly tight vapour seal should be used Smaller cabinet should be used Bigger cabinet should be used ANSWER DOWNLOAD EXAMIANS APP
