A refrigerator operates between $120$ kPa and $800$ kPa in an ideal vapor compression cycle with $R-134a$ as the refrigerant. The refrigerant renters the compressor as saturated vapor and leaves the condenser as saturated liquid. The mass flow rate of the refrigerant is $0.2$ kg/s. Properties for $R-134a$ are as follows:
The rate at which heat is extracted, in Kj/s from the refrigerated space is
- $28.3$
- $42.9$
- $34.4$
- $14.6$
