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 - td₂)/(td₃ - td₁) (td₃ - td₁)/(td₃ - td₂) (td₃ - td₁)/(td₂ - td₃) (td₂ - td₃)/(td₃ - td₁) (td₃ - td₂)/(td₃ - td₁) (td₃ - td₁)/(td₃ - td₂) (td₃ - td₁)/(td₂ - td₃) (td₂ - td₃)/(td₃ - td₁) ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning In a vapour compression refrigeration system, a throttle valve is used in place of an expander because It leads to significant cost reduction The positive work in isentropic expansion of liquid is very small It improves the C.O.P., as the condenser is small It considerably reduces mass of the system It leads to significant cost reduction The positive work in isentropic expansion of liquid is very small It improves the C.O.P., as the condenser is small It considerably reduces mass of the system ANSWER DOWNLOAD EXAMIANS APP
