Answer: When pressure increases, Temperature increases. When there is drop in pressure there is also a drop in temperature.

Explanation:

Forced air conditioning also known as central air conditioning unit uses a forces cooled through ducts into buildings.

Gay Lussac law states that the the pressure of a given mass of gas is directly proportional to its temperature provided volume is remains constant. How this relates to a the operation of a forced air conditioning unit is, Because the refrigerant is in closed cycle in the system it volume is always constant expect in a case where there is a leakage. As pressure increases in the system, This increase in pressure and temperature usually takes place at the discharge side of the compressor.

When pressure decreases in, so does the temperature in they system. This change or drop in pressure and temperature is noticeable when the refrigerant is returning back from the evaporator to the compressor through it suction outlets during the refrigeration cycle.
