What is a cooling vacuum pump?

The cooling vacuum pump is a device used to clean the air conditioning and cooling systems (AC/R) of contaminants such as moisture and air. This cleaning effect is achieved by induction of a deep vacuum in the system continuously by pulling a small amount of gas during the lengthy period. During this process, any water in the system and the resulting steam is cooked and any air is pulled out. Vacuum pumps cooling are usually rotary variants, many of which have two phase operations. The vacuum values ​​concerned are expressed in microns with an average two -stage vacuum pump capable of producing 50 microns or less.

Cooling and air -conditioning systems are often contaminated by moisture and unpredictable gases such as air. The presence of one or both of these elements in the AC/R system can cause serious problems such as internal icing and corrosion. If signs of these contaminants are detected or if the refrigerant has been annoying repair, the system will have to be cleaned. Include itE Connect the vacuum pump cooling with the system and allowing it to run until the time of the acceptable vacuum is drawn.

The privileged radiator pump is used to remove air and humidity in two ways. The first is the physical drawing of air and water vapor from the system along with any remaining refrigerant charge. Unfortunately, the moisture in liquid form can be pulled out of the system and must be converted to gas or steam to facilitate its removal. The cold vacuum pump creates extremely low pressures in the system, causing water to boil at the room temperature and drawn like steam.

Cooling vacuum pumps are usually out-SET rotary or sliding pumps. Many deep vacuum pumps have twins, which are basically two identical pumps in the series. This type of pump can easily pull out a vacuum of 250 microns and can even produce a pressure of 50 microns or lessE. To illustrate the depth of this type of vacuum, the pressure of the air on the sea level is approximately 760,000 microns!

The

cooling vacuum pumps are available in a series of capacity rating ranging from 1.2 to 10 cubic feet per minute (CFM). It is important to ensure that the vacuum pump used is appropriately evaluated for the specific size of the AC/R system in question. Using too small pump can cause unnecessary wear and possible damage. It is also necessary to maintain the correct oil level in the vacuum pump of the cooling vacuum during flushing operations.
