How to add air conditioning refrigerant

Turn off the power supply of the air conditioner first; if all the light leaks, then you must evacuate before adding it; find the thick tube under the outdoor unit and add fluorine from here; you need to install the pressure gauge when adding fluorine Generally, it can be stopped at about 5 pressures; the temperature needs to be turned to the lowest when turning on the machine, and observe for about half an hour.

The principle of air-conditioning compressor

Abstract: The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. Air-conditioning compressors are generally installed in outdoor units. What is the principle of air-conditioning compressor? What is the reason why the air conditioner compressor does not start? How to replace the air conditioner compressor? The compressor is the heart of the refrigeration system of the air conditioner. The refrigerant circulation or flow in the system is achieved by the operation of the compressor. Once the compressor stops, cooling is over. The compressor compresses the refrigerant as<img src="{{media url=&quot;magefan_blog/The_principle_of_air-conditioning_compressor.jpg&quot;}}" alt="" />

Introduction to the development momentum and types of medium and high pressure screw air compressors

Screw air compressors have basically replaced other types of air compressors in the low pressure field. Also in the low-pressure field, as compared to special gas compressors, screw air compressors have gradually shifted from tentative intervention to a trend of big steps.
