High temperatures of refrigerant go through the cold air across capacitor five and tubing by fan. It will ensue refrigerating become high force per unit area liquid without alteration the force per unit area.

FILTER DRIER: A A A A A A A A A

Filter used to take wet. The most ground is to avoid corrosion which leads to the terrible system failure. A A A

EXPANSION DEVICE: A

Expansion valve is a constituent that used to command refrigerating flow into the evaporator thereby commanding superheated air at the mercantile establishment of the evaporator.

EVAPORATOR: A A A A A A A A A A A

An evaporator used to vaporize liquid to gas by take downing the force per unit area until it boiling point. Since the evaporating temperature is lower than environing ; so air is seeking to chill.

Heating Ventilating Air Conditioning and Refrigeration ( HVACR ) system in Agriculture Industries

HVACR system in Malaysia agribusiness more directed to the storage of natural stuffs or storage of agricultural merchandises that do non last long. Among them are such as piscaries beginning, meat and veggies and fruit. Additionally, HVCAR besides used in farm animal agriculture sector. HVACR give benefit to Malaysia agribusiness industries to assist husbandmans increase the productiveness and more competitively.
