Refrigeration, Air Conditioning Compressors: Reciprocating, Rotary, Screw, Centrifugal, Scroll

What is Refrigeration Compressor The compressors are one of the most important parts of the refrigeration cycle. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. It is the crucial function that is performed by the compressor. Compression of the refrigerant to the suitable pressure ensures its proper condensation and circulation throughout the cycle. The capacity of the refrigeration or air conditioning depends entirely on the capacity of the compressor.<img src="{{media url="422C8FF7C729C6E9A7416FCA7C2EB508849153E1_large.jpg"}}" alt="" />

Common system failures of refrigeration equipment

Common system failures of refrigeration equipment 1. Liquid return: For refrigeration systems using expansion valves, liquid return is closely related to the selection and use of expansion valves. Expansion valve selection is too large, the superheat setting is too small, the installation method of the temperature sensor is incorrect, the insulation bandage is damaged, and the expansion valve failure may cause liquid return.<img src="{{media url="Common_system_failures_of_refrigeration_equipment2.png"}}" alt="" />

Composition principle of refrigeration system of refrigerator

Composition principle of refrigeration system of refrigerator Refrigerators have a larger cooling capacity than household refrigerators, and there are more refrigerants filled in the system. Therefore, a liquid storage tank is installed on the pipeline between the condenser and the filter, and a shut-off valve is installed on the tank to shut down the system for a long time. When closing the shut-off valve, the refrigerant liquid is stored in the tank.<img src="{{media url="Composition_principle_of_refrigeration_system_of_refrigerator.jpg"}}" alt="" />

Working principle of sliding vane compressor <img src="{{media url="magefan_blog/Working_principle_of_scroll_compressor_Characteristics_of_scroll_compressor.jpg"}}" alt="" /> 　　 Air is sucked in through a filter and a regulating proportional valve. The regulating valve is mainly used to regulate the pressure chamber formed by the rotor and slide of the air cylinder. The rotor rotates eccentrically with respect to the cylinder, the valve plate is installed in the rotor groove, and the slider is pushed to the cylinder wall by centrifugal force.

The role of condensing pressure regulating valve

Condensing pressure regulating valve 　　 When the refrigeration device is running, if the condensing pressure is high, the compressor discharge temperature will rise; the compression ratio will increase; the cooling capacity will decrease; The higher the condensing pressure, the greater the above adverse effects. The high condensation pressure is mainly seen in summer. <img src="{{media url="The_role_of_condensing_pressure_regulating_valve.jpg"}}" alt="" />

Structure diagram of single vane compressor_Main features of single vane compressor

　　 The basic structure and working principle of single slide compressor.<img src="{{media url="Structure_diagram_of_single_vane_compressor_Main_features_of_single_vane_compressor.jpg"}}" alt="" /> Single sliding vane compressor is also called scraper compressor or rolling rotor compressor. Its structure is shown in Figure 3-7. A cylindrical eccentric rotor (also called a piston) is installed in the cylinder, and the center of rotation of the rotor coincides with the center of the cylinder. In the middle of the upper part of the cylinder, a scraper that can slide up and down is installed. Due to the force of the spring,<img src="{{media url="Structure_diagram_of_single_vane_compressor_Main_features_of_single_vane_compressor2.jpg"}}" alt="" />

Scroll compressor structure diagram_Scroll compressor advantages and disadvantages

Scroll compressor structure diagram <img src="{{media url="Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages.jpg"}}" alt="" /> 　　 Scroll compressor is a positive displacement compression compressor, the compression component is composed of moving scroll and static scroll. Its working principle is to use the relative orbital motion of the movable and static scrolls to form a continuous change in the enclosed volume, so as to achieve the purpose of compressing gas. Mainly used in air conditioning, refrigeration, general gas compression, and used in automobile engine supercharger and vacuum pump, etc., it can replace traditional medium and small reciprocating compressors in a large range. <img src="{{media url="Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages2.jpg"}}" alt="" />
