The Necessity of EvacuationIn a refrigerant system, only the refrigerant and oil should be circulating. During servicing or after many years of operation, the air may enter the system. The air from the atmosphere that enters the system include oxygen, nitrogen and moisture. These unwanted components will cause:
Rise in head pressure causing higher discharge temperatures and compression ratios. Efficiency of the system is reduced.Acids are produced in the refrigerant causing chemical reaction resulting in electroplating and damage to the motor insulation. Once the insulation in the compressor motor breaks down, short circuit will happen hence damaging the compressor. The compressor is one of the highest equipment cost in the system. Acids also cause corrosion to the metal parts over time.Sludge is formed by a combination of oil, acid and moisture in the system. It will cause improper operation to the filter drier, strainers and expansion device over a period of time.

Air Conditioning Vacuum Pump OperationIn order to remove all the unwanted moisture and gases from the refrigerant system, a state of near vacuum has to be achieved in which the pressure in the system is forced to go below the atmospheric pressure. The absolute value of the atmospheric pressure at sea level is given by 29.92 in. Hg or 14.696 psia or 759.999 mm Hg or 759,999 microns.
In the typical system, the vacuum pump is required to create a vacuum state of about 300 to 500 microns. An electronic vacuum gauge is needed to measure the level of vacuum in the system. Check the specifications of the vacuum pump and make sure that it is able to achieve the vacuum state as required by the manufacturers of the equipment.

A 2-Stage Vacuum Pump from Robinair

Rotary compressors are used in the pumps and the better ones that are able to produce the lowest vacuums are the 2-stage rotary vacuum pumps. However, they are more costly but their abilities to remove moisture effectively is one of the main reasons why many technicians prefer to purchase this model.
As the system enters low vacuum state, the moisture will begin to boil and becomes vapor enabling its removal from the system easily.
Proper oil needs to be used when operating the air conditioning vacuum pump. Use only the recommended oil to enable the pump to achieve the specified vacuum state.
Take note of the followings when selecting air conditioning vacuum pump.
Sight glass oil to see the level of oil before operating.Anti-suckback feature that will prevent the oil from the pump from flowing into the refrigerant system in the event of power failure. The oil in the refrigerant is different from the ones in the pump.CFM rating. The higher the cfm, the faster the evacuation process is.One-Stage or Two-Stage design.The lowest vacuum level that the pump can achieve.Intake fittings.Weight
Good for all Hvac system which include RACS, SPLITS, PACKAGE UNITS, AHU, FCU, CENTRAL ACS.220 VOLTS50/60HZ 1/4HP CAPACITY 1500 RPM
