Refrigeration and Air Conditioning In order to cool and dehumidify a stream of moist air, it must be passed over the coil at a temperature Which lies between the wet bulb and dew point temperatures of the incoming stream Of adiabatic saturation of incoming stream Which is lower than the dew point temperature of the incoming stream Which lies between the dry bulb and wet bulb temperatures of the incoming stream Which lies between the wet bulb and dew point temperatures of the incoming stream Of adiabatic saturation of incoming stream Which is lower than the dew point temperature of the incoming stream Which lies between the dry bulb and wet bulb temperatures of the incoming stream ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning The bypass factor, in case of sensible cooling of air, is given by (where td₁ = Dry bulb temperature of air entering the cooling coil, td₂ = Dry bulb temperature of air leaving the cooling coil, and td₃ = Dry bulb temperature of the cooling coil) (td₂ -td₃)/( td₁ -td₃) (td₃ -td₁)/( td₂ -td₃) (td₁ -td₃)/( td₂ -td₃) (td₃ -td₂)/( td₁ -td₃) (td₂ -td₃)/( td₁ -td₃) (td₃ -td₁)/( td₂ -td₃) (td₁ -td₃)/( td₂ -td₃) (td₃ -td₂)/( td₁ -td₃) ANSWER DOWNLOAD EXAMIANS APP
