The layout principle of Freon refrigerant pipeline

The main feature of Freon refrigerant is that it dissolves with the lubricating oil. Therefore, it must be ensured that the lubricating oil from each refrigeration compressor can return to the refrigeration compressor after passing through the condenser,

Danfoss medium temperature refrigeration compressor M series

liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.

Brief Discussion on Service Coefficient of Air Compressor Related Motor

The term motor service factor comes from the "MG1-2009 Motor and Generator Part" standard compiled and published by the National Electrical Manufacturers Association (NEMA), commonly known as the NEMA MG1 standard.

Refrigerator Solenoid Valves: Structure and Working Principle

The refrigerator solenoid valve is mainly used to change the flow direction of the refrigerant to control the cooling temperature of different compartments of the refrigerator (refrigerator compartment, freezer compartment, and variable temperature compartment).

Common faults and causes of compressors

Common faults and causes of compressors Common compressor failures are as follows: 　　L. The compressor cannot start normally 　　 The power supply voltage is too low, the motor circuit is poorly connected, or the exhaust valve is leaking, resulting in too high pressure in the crankcase. The energy regulation mechanism has failed.

Reasonably adjust the cold storage evaporator and defrost in time

Reasonably adjust the cold storage evaporator and defrost in time Generally speaking, every increase in the cold storage evaporation temperature can save energy Therefore, under the premise of satisfying the low refrigeration process of the product, the evaporation temperature can be increased as much as possible by adjusting the amount of liquid supplied. The thermal resistance of the frost layer is generally much larger than the thermal resistance of the steel pipe.

The difference between chilled water, cooling water and condensed water and the principle of refrigeration

The central air-conditioning host is composed of a compressor, an evaporator, a condenser, and a throttle valve. The compressor provides energy. The condenser reduces the temperature of the refrigerant from the compressor.

Use and principle of inverter air conditioner and ordinary air conditioner

Inverter air conditioners are based on ordinary air conditioners with special inverter compressors, and an inverter control system is added. Its basic structure and cooling principle are exactly the same as ordinary air conditioners.

Why is the air conditioner not cooling

1.Check whether the compressor is working normally. If the compressor is broken, the air conditioner cannot start normally and there will be no cooling effect. 2. There is not enough refrigerant in the air conditioner. At this time, you need to add Freon, and the time for adding Freon can be very long. 3. The air conditioner itself has quality problems and the electrical components have failed. In this case, you need to find a master to repair it.
