Equal to Less than None of these Greater than Equal to Less than None of these Greater than 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 It considerably reduces mass of the system The positive work in isentropic expansion of liquid is very small It leads to significant cost reduction It improves the C.O.P., as the condenser is small It considerably reduces mass of the system The positive work in isentropic expansion of liquid is very small ANSWER DOWNLOAD EXAMIANS APP
