ESCO Air Conditioning Practice Exam

In the evaporator

1. Latent heat is absorbed by the refrigerant from the refrigerated space

2. Latent heat is released to the refrigerated space

3. Sensible heat is absorbed by the refrigerant

4. Sensible heat is released to the refrigerated space

The correct answer is: Latent heat is absorbed by the refrigerant from the refrigerated space

In the evaporator, latent heat is absorbed by the refrigerant from the refrigerated space. This absorption of latent heat is a crucial part of the refrigeration cycle. As refrigerant passes through the evaporator coils, it evaporates by absorbing heat from the surrounding air or space. This process cools the air or space being refrigerated. Therefore, Option A is the correct answer. Sensible heat, on the other hand, is heat that can be measured by a change in temperature and is not directly related to phase change (solid to liquid, liquid to gas). Sensible heat is typically absorbed by the refrigerant in the condenser rather than the evaporator. Therefore, Options B, C, and D are not characteristic of the evaporator in the refrigeration cycle.
