Question

A walk-in cooler using a vapor compression refrigeration cycle is configured as shown below.

The cycle uses CFC22 or R22 as the refrigerant. Assume frictionless flow through all piping and

heat exchangers (e.g. neglect pressure drops except through the expansion valve). Assume

saturated liquid leaves the condenser and saturated vapor leaves the evaporator. A heat

exchanger is used to transfer thermal energy between the hot liquid leaving the condenser and

the cold vapor leaving the evaporator. Assume this heat exchanger has perfect external insulation

so the only energy transfer is between the two fluids. The main purpose of this heat exchanger is

to prevent liquid from entering the compressor and damaging it. Known data are: T1=30 °C, T2=10 °C and T4= -10 °C.

What are C of P and T(6)?
