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.

Eight advantages of air compressor waste heat recovery device

During the operation of the air compressor, about 80% of the input electric energy will become heat, and the remaining 20% ​​will eventually become compressed air energy. After the electric energy consumed by the compressor is converted into heat in the working process, most of it is taken away by the compressed special mixture

Application of synthetic compressor oil

At present, synthetic lubricants are widely used in the compressor field. Among them, oil-injected and oil-immersed rotary screw air compressors and large reciprocating compressors are one of the most used markets. For example, the sales volume of synthetic compressor oil in Western Europe was 6000t in the late 1980s, and it rose to 10000 in the early 1990s. The sales volume in the United States has exceeded 15,000 tons, and it is increasing at a rate of more than 10% per year.

Compressor failure and elimination

The compressor is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant liquid to the exhaust pipe to provide power for the refrigeration cycle.

What kind of equipment is generally used in cold storage How to select the refrigeration equipment

The cost of cold storage with a refrigeration capacity of less than 60kw is relatively large. It is generally suitable for small cold storage and air conditioning units. The cost of such small cold storage within 100 square meters ranges from 30,000 to 100,000.
