Evaporator Temperature (°F)

Condenser Temperature (°F)

Refrigerant Type

Cooling Load (BTU/hr)

Actual COP

Carnot COP

8,234

Compressor Work BTU/hr

44,234

Heat Rejection BTU/hr

720

Mass Flow Rate lb/hr

Formula:

COP_{Carnot} = \frac{T_{evap}}{T_{cond} - T_{evap}}

Calculation:

COP_{Carnot} = \frac{277.6}{322.0 - 277.6}

Result:

6.25 \text{ }

Formula:

COP = \eta \times COP_{Carnot}

Calculation:

COP = 0.70 \times 6.25

Result:

4.37 \text{ }

Formula:

W = \frac{Q_{load}}{COP}

Calculation:

W = \frac{36000}{4.37}

Result:

8234 \text{ BTU/hr}

Formula:

Q_{reject} = Q_{load} + W

Calculation:

Q_{reject} = 36000 + 8234

Result:

44234 \text{ BTU/hr}
