COP of Air Cycle given Input Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Actual Coefficient of Performance = (210*Tonnage of Refrigeration in TR)/(Input Power*60)
COP_actual = (210*Q)/(P_in*60)
This formula uses 3 Variables

Variables Used

Actual Coefficient of Performance - The actual coefficient of Performance is the ratio of the actual cooling effect produced to the actual power consumption.
Tonnage of Refrigeration in TR - The Tonnage of Refrigeration in TR is defined as the rate of heat transfer that results in the freezing or melting of 1 short ton of pure ice at 0 °C in 24 hours.
Input Power - (Measured in Watt) - Input Power is the power, which is required by the appliance at its input i.e., from the plug point.

STEP 1: Convert Input(s) to Base Unit

Tonnage of Refrigeration in TR: 3 --> No Conversion Required
Input Power: 2.7 Kilojoule per Minute --> 45.0000000000001 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

COP_actual = (210*Q)/(P_in*60) --> (210*3)/(45.0000000000001*60)

Evaluating ... ...

COP_actual = 0.233333333333333

STEP 3: Convert Result to Output's Unit

0.233333333333333 --> No Conversion Required

FINAL ANSWER

0.233333333333333 ≈ 0.233333 <-- Actual Coefficient of Performance
