Japan Daikin, Hitachi and Mitsubishi Electric air-conditioning compressor comparison

Japan Daikin, Hitachi and Mitsubishi Electric air-conditioning compressor comparison First, take a look at Daikin. The use of high and low pressure cavity scroll compressor and swing compressor 1. In high and low pressure cavity scroll compressors, Daikin applies super metal materials to the field of air-conditioning compressors. The application of six-pole high-efficiency motor enhances the efficiency of magnetic cutting. Cooperate with high-efficiency filtering technology to improve motor efficiency. 2. In the swing compressor, the swing compressor is also a type of rotor compressor. Compared with the traditional rotor type, the swing type is an integrated design of the rotor and the blade, although it is only a small change. However, the requirements for the mold and process are high, and the accuracy is as low as micrometers. Second, look at Mitsubishi Electric. Mitsubishi Electric is also a skilled person in the field of compressors. There are many types of compressors. High-pressure chamber scroll compressors ANB series and low-pressure chamber scroll compressors ENB/HNB series and double rotor series are used. 1. The first one has a patented scroll structure with improved design. In addition to the movable scroll, Mitsubishi Electric has also specially set up a patented "frame structure". 2. In the second type, Mitsubishi Electric's original keel motor achieves high-efficiency motors, and large capacity is the key to reliable operation. Even if it is switched on and off frequently, it can ensure stable oil supply and reduce noise. 3. The third kind, compared with the single rotor compressor, can run smoothly, low noise and high efficiency from low speed to high speed. 3. Finally, take a look at Hitachi. The high-pressure cavity scroll compressor and double-rotor compressor are used 1. Hitachi is the inventor of the world's first scroll compressor. Hitachi Large Capacity Scroll Compressor adopts a new driving mechanism to effectively prevent the decline in capacity caused by the excess refrigeration oil in the refrigeration cycle, and the efficiency is further improved. At the same time, using IPM (in-rotor embedded) technology, the torque is increased by 20%, the motor efficiency is further improved, and it is more energy-saving than AC motors and traditional DC motors. 2. Hitachi double rotor series is a high-end product in air conditioner, with sufficient power and very fast cooling speed. to sum up: 1. Comparison of high-pressure chamber (Hitachi and Mitsubishi Electric) and high-low pressure chamber (Daikin) The advantages of the high-pressure chamber compressor: the refrigerant directly enters the compression chamber to compress, there is no invalid preheating, and the efficiency is higher. Stable oil supply and low energy consumption. Disadvantages of high-pressure chamber compressors: no high and low pressure separators, easy to produce heat loss from high pressure side to low pressure side Advantages of high and low pressure chamber compressors: high and low pressure chamber compressors are equipped with high and low pressure partition plates to avoid ineffective heat loss, higher efficiency, and stronger sealing. Disadvantages of high and low pressure chamber compressors: the exhaust gas with higher temperature cools the motor, so the processing technology of the motor is required higher. 2. In the above two compressors-one is scroll type and the other is rotor type, according to years of tests and calculations, 6 horsepower is the critical point of compressor performance, and rotor compressors below 6 horsepower are more For high efficiency, it is more efficient to adopt the scroll type for more than 6 horses. 3. The advantage of Daikin compressor is the use of new materials, advanced technology and precise control system; 4. The advantages of Mitsubishi compressors are the excellent motor performance, and the core technology of both scroll and double rotor compressors with high pressure chamber and low pressure chamber; 5. The advantages of Hitachi compressors are the inventors and leaders of scroll compressors, with 32 years of technology precipitation, second to none in the stability of compressor performance Warm reminder: Daikin, Mitsubishi Electric and Hitachi are all excellent air-conditioning brands. It is not wrong to choose anyone, depending on which flavor you like to decorate, and whether your decoration budget is enough!
