Why is the air conditioner not cooling

1.Check whether the compressor is working normally. If the compressor is broken, the air conditioner cannot start normally and there will be no cooling effect. 2. There is not enough refrigerant in the air conditioner. At this time, you need to add Freon, and the time for adding Freon can be very long. 3. The air conditioner itself has quality problems and the electrical components have failed. In this case, you need to find a master to repair it.

Harmfulness of air compressor motor direct full pressure start and the benefits of motor soft start cabinet

With the development of my country's economy, the application of motors is increasing, and people's attention is paid to the starting method of motors. Generally speaking, the motor soft start cabinet should be used when the motor power exceeds 30KW, otherwise it will seriously affect the operation of other equipment in the power grid and damage the motor itself.

Compressor protection measures against liquid strikes

Compressor protection measures against liquid strikes When too much liquid enters the cylinder and it is too late to discharge it from the exhaust valve, a liquid blow will occur in the cylinder. The high pressure generated during the liquid blow damages the cylinder, piston, connecting rod, etc., so it is necessary to take a Series of protective measures.
