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