WebThe required values of enthalpy for the inlet and outlet ports are determined from the R134a refrigerant tables. The high pressure superheated refrigerant at port (2) is now directed to a condenser in which heat is extracted from the refrigerant, allowing it to reach the subcooled liquid region at port (3). WebA refrigeration circuit is to cool a room at 0°C using outside air at 30°C to reject the heat. The refrigerant is R134a. The temperature difference at the evaporator and the condenser is 5 K. Find the Carnot COP for the process, the Carnot COP for the refrigeration cycle and the ideal vapour compression cycle COP when using R134a.
