What should I do if the geothermal exhaust valve leaks

Water leakage from the geothermal exhaust valve is very common. Under normal circumstances, when the heating is first delivered in winter, the geothermal pipe needs to be exhausted so that the exhaust can make the heating of the underfloor heating loop uniform.

Methods of handling sudden failures of precision air conditioners

1. Leakage treatment steps for precision air conditioning units 　　Leak handling operation precautions: Never destroy the vacuum artificially. If it is not certain that the unit has indeed leaked air into the unit, operation cannot be performed.

How to protect the refrigeration compressor, you must master the following knowledge!

When the compressor is running, some abnormal conditions may occur, such as: exhaust pressure is too high, suction pressure is too low, oil pressure is insufficient, motor is overheated, excess liquid enters the cylinder, etc. In the event of an abnormal situation, the compressor will be damaged if there is no protective measure.

Treatment method after load damage of screw chiller

First of all, we must confirm whether the compressor load has been burned or the components have been worn away. If so, the refrigerant system will inevitably be contaminated. For example, residual refrigerant oil remains in the pipeline after carbonization

How to use refrigerant to empty the air conditioner after installation

Air, moisture and impurities contained in the air will cause pressure increase, current increase, noise increase, and power consumption increase in the air conditioner system, which will reduce the cooling (heat) capacity, and may also cause ice blockage and dirty blockage.
