What causes the exhaust temperature of the refrigeration compressor to be too high

What causes the exhaust temperature of the refrigeration compressor to be too high Refrigeration compressor is a kind of equipment commonly used in air conditioning and refrigeration. Without it, the air conditioner cannot be cooled normally. However, refrigeration compressors often encounter many problems in normal use. For example, the exhaust steam temperature is too high. 　　Now, let’s take a look at the causes of the excessively high exhaust temperature of refrigeration compressors: 　　①The steam is too hot; 　　②Condensation pressure is too high; 　　③The return steam pressure is too low; 　　 ④ The cooling water of cylinder head is insufficient; 　　 ⑤ The clearance at the top dead center of the piston is too large.
