DC variable frequency electric scroll compressor
DC variable frequency electric scroll compressor
The electric scroll compressor is mainly composed of moving scroll plate, stationary scroll plate, driving motor, anti-rotation mechanism, one-way valve and other components. During operation, gaseous refrigerant enters the crescent-shaped compression chamber on the periphery of the stationary scroll plate from the suction port. As the moving scroll plate rotates, the volume of the compression chamber gradually decreases, the refrigerant is continuously compressed, and its pressure and temperature rise. Eventually, it is discharged from the exhaust port at the center of the stationary scroll plate, enters the condenser of the air-conditioning system, condenses into liquid refrigerant after heat dissipation, then passes through the expansion valve for throttling and pressure reduction, and enters the evaporator to absorb heat through evaporation, thus realizing the refrigeration cycle. In the heating mode, the flow direction of the refrigerant is changed through the four-way reversing valve to achieve heating.
The electric scroll compressor has the following major advantages:
• Drive and Structure: It is directly driven by a motor, has a scroll structure, is small in size and light in weight, and is convenient for installation and layout.
• Operating Performance: It has a fast response speed, precise temperature control, low operating noise, good refrigeration and heating effects, and is not limited by the engine speed.
• Energy Efficiency Performance: It can automatically adjust the power output, with significant energy-saving effects, which can improve the energy utilization rate.
• Maintenance: It has few parts, low wear, long service life, and low maintenance cost, and there is no need to frequently replace wearing parts.
• System Compatibility: It is highly integrated with the electronic control system, enabling intelligent control and coordinated work.
