EQUIPMENT IN THE REFRIGERANT SYSTEM

 COMPRESSOR (REFRIGERANT SYSTEM)

The compressor unit is a device to compress the low pressure and temperature refrigerant gas which was evaporated in the evaporator so the gas can be easily liquidized. The compressor unit in this package air conditioner is hermetic type that the compressor and electric motor are encased in the single casing and hermetically sealed. Therefore, trouble of refrigerant leakage, operation noise and vibration are minimized.

 CONDENSOR

The condenser is a device in which the high pressure and high temperature refrigerant gas from the compressor unit is cooled and liquidized. At this time, heat is taken away from the refrigerant gas by cooling water or air.

 EXPANSION VALVE

The expansion valve is device in which the high pressure and high temperature liquid refrigerants  from the condenser is released so that it can be evaporated at the design temperature. The expansion valve in this package air conditioner is the thermal expansion valve.

 SOLENOID VALVE

The liquid solenoid valve in the packaged air conditioner is a device which interrupts or delivers the flow of liquid refrigerant in pipe by electric function.

 EVAPORATOR

The evaporator is a device in which the low pressure and low temperature liquid refrigerant from the expansion valve evaporated itself taking heat from air passing through the evaporator. The evaporator in this package air conditioner is the fin and tube type which consist of anti-corrosive aluminum fins attached to copper tube.

 FILTER DRAYER

The filter dryer is attached to remove the moisture and foreign objects from the refrigerant cycle.

AIR FILTER

The air filter is attached before the evaporator to remove the dust and dirt from the air. If the dust and dirt attached to the air filter increase, the resistance to air will increase accordingly and cooling capacity decrease. Therefore, the air filter should be cleaned at times.
