AIR CONDITIONER

DEFINITIONA system of process for controlling the lowering the temperature dan humidity of an enclosed space.

COMPRESSORInhaling the refrigerant from the suction channel- Compressing to the discharge channel. Hot refrigerant

vapor and high pressure

CONDENSORRemove heat from condenserRefrigerant vapor turn to liquid.

Hot refrigerant vapor and high pressure

EXPANSION VALVELow the temperature and pressure of liquidControl the flow rate into the evaporator.

Cold refrigerant vapor and low pressure

EVAPORATORLiquid turns to vaporCold air flows out room.

Cold refrigerant vapor and low pressure

Package Air-conditioning System

Used for the cooling capacities in between these two extremes.

The packaged air conditioners fixed rated capacities of 3, 5, 7, 10 and 15 tons.

Used commonly in places like restaurants, telephone exchanges, homes, small halls.

Low Statics Fan Coil

• One or more heat exchangers

• One or more fans with electric motors

• An appropriate enclosure,

• Condensed water collecting facilities when cooling

COMMON AIR CONDITIONER PROBLEMS

Refrigerant leaks can happen with vibration of the unit while it is operating.

Dirty A/C units wont operate at peak efficiency. (Coil Condensor)

 One possible reason that HVAC systems blow warm air is dirty filters.

Frozen coils are causes circulation problems.
