In this Video,I explained the Numerical of Vapour Compression Refrigeration System.
and i find out Following parameter,
Calculate the Refrigerating effect and COP.
If (a) the refrigerant leaves the condenser saturated.
(b) the refrigerants is sub cooled to 20c before entering the throttle valve.

An ideal vapor-compression heat pump cycle with Refrigerant 134a as the working fluid provides heating at a rate of 15 kW to maintain a building at 20°C when the outside temperature is 5°C. Saturated vapor at 2.4 bar leaves the evaporator, and saturated liquid at 9 bar leaves the condenser. Calculate (a) the power input to the compressor, in kW (b) the coefficient of performance (c) the coefficient of performance of a Carnot heat pump cycle operating between thermal reservoirs at 20 and 5°C


Can you solve this ?

How did u come to conclusion that the inlet of compressor has mixture of gas and liquid?
