Question

Describe the psychrometric process used for ‘summer air conditioning’.

Hint:

Summer AC = cools the air + removes extra humidity!

Answer 1

Summer air conditioning aims to keep indoor spaces cool and comfortable during hot and humid weather.
The main psychrometric process used is cooling and dehumidification.
In this process, warm and humid air from the room is drawn into the air conditioning unit.
The air passes over a cooling coil that is colder than the dew point temperature of the air.
As a result, the air temperature drops and moisture condenses out, reducing humidity.
The cooled and dehumidified air is then supplied back into the room to maintain desired conditions.
This improves comfort by lowering both temperature and humidity.
This process is essential for comfort cooling in homes, offices, and commercial buildings during summer.
