DC variable frequency electric scroll compressor
The electric scroll compressoris 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.
Currently, our company can provide air-conditioning compressors with displacements such as 14CC, 18CC, 28CC, 34CC, and 50CC, accurately meeting the refrigeration requirements of different scales and working conditions. In terms of voltage adaptation range, it covers diverse options such as 12V, 24V, 48V, 96V, 144V, 312V, and 540V. Currently, it can support a maximum voltage of 800V, being able to perfectly match various power system architectures. Its control modes include advanced forms such as gear, PWM (Pulse Width Modulation), and CAN (Controller Area Network), and the refrigeration capacity output range is wide, ranging from 0.8kW to 15kW. Whether it is the efficient operation of small refrigeration units or the strong refrigeration demands of large refrigeration systems, it can handle them with ease, stably exerting excellent performance and presenting reliable and customized refrigeration solutions to customers.
The application scenarios of the R134a/R1234yf series of electric air-conditioning compressors are as follows:
In the field of new energy vehicles:
• Cabin Air-Conditioning System: Carefully adjust the temperature of the vehicle cabin to create a comfortable and pleasant temperature environment for the occupants.
• Battery Thermal Management: Precisely control the working temperature range of the battery, effectively enhancing the battery performance and service life, and providing a solid guarantee for the driving range and safety of new energy vehicles.
• Cooling of Motor and Electronic Control Systems: Efficiently reduce the heat generated during the operation of the motor and electronic control systems, eliminating the risk of overheating damage and ensuring their normal and stable operation and performance stability.
In the field of commercial vehicles:
• Refrigeration and Heating during Normal Driving: Thoughtfully create a comfortable driving and riding environment, significantly improving the riding comfort of commercial vehicles.
• Parking Air-Conditioning: During vehicle parking, freely provide refrigeration or heating functions, fully meeting the drivers' requirements for the vehicle interior temperature during rest or waiting, effectively saving fuel consumption or battery power when the vehicle is idling.
In the field of special vehicles:
• Fire Engines: Fully ensure the comfort of firefighters during the execution of tasks and ensure the stable operation of various equipment at an appropriate temperature.
• Medical Ambulances: Meticulously create a comfortable temperature environment for the patients and medical staff in the vehicle, while ensuring the normal use of medical equipment.
In the field of energy storage: The electric air-conditioning compressor is applied to the cooling system of energy storage cabinets, effectively preventing the performance and service life of energy storage equipment from being affected by excessive temperature during the charging and discharging process.
In the home field: Electric air-conditioning compressors that have undergone special design or modification can be used to make small mobile air conditioners or substitutes for household air conditioners to meet the refrigeration requirements in specific scenarios.
