Causes of compressor refrigerant backflow Compressor refrigerant backflow can be caused by a variety of situations. Most of the causes can be attributed to: 1. Evaporator problems. 2. Overcharge and/or improper capillary tube size. 3. Faulty or improperly adjusted expansion valve. 4. Refrigerant migration. Solutions for continuous compressor refrigerant backflow 1) Check the selection and

The Hidden Dangers of Ice Accumulation While commercial cold rooms preserve 85% of food freshness compared to 30% in conventional refrigeration (USDA data), ice buildup can reduce efficiency by up to 40% and increase energy costs by 25-30% according to ASHRAE studies.

Capacity control is a device that increases the efficiency of single-stage compressors. It is based on suction cut-off and control so that gas cannot flow to individual cylinders. At 100% load, the compressor opens all cylinders and the solenoid valves are closed. At partial load, the compressor opens some cylinders and the solenoid valves are

Different fruits and vegetables have different storage temperatures. Four temperatures can be roughly summarized. 1. Above 10 degrees Celsius. Cold storage above 10 degrees Celsius can store tropical fruits. Tropical fruits are prone to rot at low temperatures. For example, dragon fruit should be stored at 15 degrees Celsius and the humidity should be kept
