Compressor Evaporator Condenser Expansion valve Compressor Evaporator Condenser Expansion valve 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 It improves the C.O.P., as the condenser is small The positive work in isentropic expansion of liquid is very small It considerably reduces mass of the system It leads to significant cost reduction It improves the C.O.P., as the condenser is small The positive work in isentropic expansion of liquid is very small It considerably reduces mass of the system ANSWER DOWNLOAD EXAMIANS APP
