Refrigeration and Air Conditioning 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) (td₃ - td₁)/(td₃ - td₂) (td₂ - td₃)/(td₃ - td₁) (td₃ - td₁)/(td₂ - td₃) (td₃ - td₂)/(td₃ - td₁) (td₃ - td₁)/(td₃ - td₂) (td₂ - td₃)/(td₃ - td₁) (td₃ - td₁)/(td₂ - td₃) (td₃ - td₂)/(td₃ - td₁) ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning One of the purposes of sub cooling the liquid refrigerant is to Ensure that only liquid and not the vapour enters the expansion (throttling) valve Reduce compressor overheating Increase cooling effect Reduce compressor discharge temperature Ensure that only liquid and not the vapour enters the expansion (throttling) valve Reduce compressor overheating Increase cooling effect Reduce compressor discharge temperature ANSWER DOWNLOAD EXAMIANS APP
