Common parameters of air compressor inverter

There are many setting parameters of the air compressor inverter, and each parameter has a certain adjustment range. In the application, it is often encountered that the air compressor inverter cannot operate normally due to the improper setting of a single parameter. Therefore, it is necessary to Make accurate settings for the relevant parameters.

The role of refrigerant in the air-cooled chiller

The refrigerant itself circulates continuously in the refrigeration system, and then realizes refrigeration through its own state changes. The refrigerant absorbs the heat of the cooling medium in the evaporator and vaporizes, and transfers the heat to the surrounding air or water in the condenser to condense.

Matters needing attention

1.Oil and water protection of servo motor 1) The servo motor can be used in the place that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. Therefore, the servo motor should not be placed or used in the environment of water or oil invasion. 2) If the servo motor is connected to a reduction gear, the oil seal should be filled when using the servo motor to prevent the oil of the reduction gear from entering the servo motor 3) The cable of servo motor should not be immersed in oil or water.

Causes of uneven liquid distribution in refrigeration systems and tragic cases!

If the distribution head is not evenly distributed, it will cause too much refrigerant in some of the branches, which will cause the evaporator to frost.
