The reason why the chiller is not cooling and there is no alarm prompt

In the process of operation, often when there is no cooling phenomenon, there is no alarm prompt, so that the operator has no way to start and does not know what caused this problem.

Analysis of the cause of excessive suction temperature of compressor

Analysis of the cause of excessive suction temperature of compressor The high suction temperature is mainly due to the increase of superheat of suction. Note that high suction temperature does not mean high suction pressure, because the suction is superheated steam. Under normal circumstances, the compressor cylinder head should be half cold and half hot. If the suction temperature is too high, the cylinder head will all heat up.

Introduction of measures for compressor pressure protection

Introduction of measures for compressor pressure protection Measures for compressor pressure protection include the following: 1. Control of suction and exhaust pressure When the compressor is running, due to the system or the compressor itself, the discharge pressure may be too high or the suction pressure may be too low. For this reason, the suction and discharge pressures need to be controlled.

On the operation principle and internal structure of air-conditioning compressor

On the operation principle and internal structure of air-conditioning compressor Regarding air-conditioning compressors, this belongs to the refrigeration system, which is generally used for air-conditioning and refrigerator cold storage, and belongs to the heart of refrigeration equipment. Air-conditioning compressors can be classified according to different principles, usually divided into two types: volume type and speed type. Volumetric air-conditioning compressors are relatively common and one of the most popular compressors.
