Question

Assuming a water-to-air mass flow ratio of 1.0 and an ambient wet-bulb of 20C (sling), calculate the air quantity likely to be handled by a cooling tower used to cool water from 32C to 27C for a refrigeration plant having a coefficient of performance of 4. (COP of 4 heat rejected at the condenser per Kw of refrigeration is 1.25 kW)

Step 1

25 kW, we can calculate the total heat rejected in the condenser. Since the COP is the ratio of the cooling effect to the work input, and the heat rejected is related to the cooling effect, we can express the heat rejected as: \[ \text{Heat Rejected} = Show more…
