Maintenance of cold storage condensing units
Daily maintenance and upkeep of cold storage refrigeration condensing units include: During the initial operation of the condensing unit, we should always observe the oil level, oil return and cleanliness of the cold room compressor. If the oil is dirty or the oil level drops, we should promptl...Read more -
Why cold storage compressor frosting ?
1-Cold storage equipment: Frost on the compressor return air port indicates that the compressor return air temperature is too low. So what will cause the compressor return air temperature to be too low? It is well known that if the volume and pressure of the same quality of refrigerant are change...Read more -
How to choose refrigeration compressor?
When choosing a cold room refrigeration compressor, the first thing to consider is the refrigeration power you need, as different types of compressors have different operating ranges. If you need low or high power, it is easy to choose from one technology. For medium-power compressors, it is diff...Read more -
Chiller cold storage construction
Fresh-keeping storage is a storage method that inhibits the activity of microorganisms and enzymes and prolongs the shelf life of fruits and vegetables. The preservation temperature range of fruits and vegetables is 0℃～5℃. Fresh-keeping technology is the main method of low-temperature preservati...Read more -
Refrigeration compressor knowledge
1. Why does the compressor have to run continuously for at least 5 minutes and stop for at least 3 minutes after shutting down before restarting?
