Question

During the sensible cooling process ________ .

सेंसिबल  शीतलन प्रक्रिया के दौरान ________।

A.

specific humidity remains constant

B.

specific humidity increases

C.

specific humidity decreases

D.

specific humidity is unpredictable

Answer ( Option A)

specific humidity remains constant

Solution

Moisture in Freon refrigeration system does not affect specific humidity (or specific humidity remains constant throughout the process).During sensible cooling process both the dry bulb (DBT) temperature and wet bulb temperature (WBT) of the air reduce, while the latent heat of the air, and the dew point temperature (DPT) of the air remain constant.

In general the sensible cooling process is carried out by passing the air over the coil.

 

Line AB = Sensible cooling

Hence, the correct option is (A).
