A vacuum pump for an air conditioner is a must-have equipment used during installation and refueling. Before filling the air conditioner with freon, it is necessary to remove air and moisture from the pipeline. Otherwise, the physical properties of the refrigerant deteriorate, and a large amount of moisture can lead to malfunctioning of the air conditioner.
Purpose of vacuum pumps
If you start the air conditioner without evacuation, the air remaining in the pipes will increase the pressure. The compressor works with increased load, produces less cold. The air in the cold line, interacting with freon, creates a small amount of acid, which reduces the insulation resistance of the compressor electric motor. The quality of freon is significantly reduced, the compressor suffers.
As a result of evacuation, the track is also cleaned of accidentally trapped debris and dust. Turning on the air conditioner without evacuation using only a freon drain is dangerous. Soon, the owner will find ice on the tubes of the cold track and the outer casing. The evacuation procedure costs significantly less than a compressor repair.
Criteria for choosing a vacuum cleaner for an air conditioner
The vacuum pump for the air conditioner is selected depending on the following parameters:
- the purpose of climate technology (industrial or domestic);
- frequency of use of a vacuum cleaner for an air conditioner;
- refrigerant piping lengths;
- vacuum depths;
- technical characteristics of air conditioners;
- cost.
The price of a vacuum pump for refueling the air conditioner depends on all these indicators and varies from 2.5 to 15 thousand rubles.
For vacuuming industrial air conditioners, the most powerful, dimensional installations providing a deep vacuum are used.
When working with domestic and semi-industrial systems, much attention is paid to the mobility of the vacuum pump for the air conditioner, its small size and weight.
The vacuum pump for air conditioners and their installation is presented on the Russian market by Chinese, American, Spanish, Taiwanese and Italian manufacturers.
Factory products from China, being several times cheaper than European or American counterparts, are in no way inferior to them in quality.
The largest selection of vacuum pumps for installing air conditioners is presented in online stores. Here you can choose 1-stage or 2-stage with a capacity of 20 to 250 liters per minute. It is also important to choose a vacuum pump for refueling air conditioners that provides the required pressure.
