Cold storage refrigeration system fault analysis and solution

Cold storage refrigeration system fault analysis and solution 2019-10-30 Exhaust pressure is too high Fault hazard: If the exhaust gas temperature is too high, the consumption of the compressor lubricating oil is increased, the oil is thinned, and the lubrication is affected; When the exhaust gas temperature is c...

Refrigeration system pipeline blockage judgment skills

System blockage has always been a difficult problem in air-conditioning maintenance. It takes time and effort to repair. Today we focus on the types of pipe system plugging and judgment techniques. It should be noted that the following blockages are caused by human factors. The following analysis is for your reference and hopes to bring some help to future repair work.

The hazard of low condensing pressure and four control methods

In winter (lower ambient temperature), the condensing pressure of the condenser is often low, so that the pressure drop across the expansion valve is reduced, and the refrigerant obtained by the evaporator is too small, resulting in a failure of the refrigeration system.

Do you know the classification and identification methods of copper pipes?

Copper pipe refers to the copper material made by pressing or drawing copper. Because of its strong and wear-resistant characteristics, it is often used in the electrical, industrial, and construction industries. Copper pipes can be produced by extrusion, continuous casting and rolling, and top-up methods.
