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="" />
