A, Hitachi air conditioning compressor?
1. At the time of design, Hitachi obtained the patent of high-efficiency DC variable-speed scroll compressor. High-end technology stepless frequency conversion technology adopts imported Hitachi high back pressure scroll compressor, and the compressor rotor adopts neodymium magnetic material, which improves its efficiency in an all-round way. Adopting stepless frequency conversion technology, the running frequency of the motor can be adjusted freely to realize stepless frequency conversion. The two-stage oil separation compressor has the function of internal oil, and an oil separator is added in the exhaust circuit of the system to realize two-stage oil separation, which makes the operation more stable and reliable.
2. In terms of function, the cooling and heating speed is fast, and DC frequency conversion control technology is adopted to accurately control the temperature to meet our needs. When starting, it can quickly reach the set temperature, and can be fine-tuned according to the indoor load, and the indoor temperature can be controlled within 0.5℃ of the set temperature. Wide operating range: when the outdoor environment is -23℃, it can meet the needs of heating in winter in cold areas of northern China.
3. In addition, the length of the refrigerant pipe between the outdoor unit and the indoor unit is very long. Meet our needs. The maximum length can reach 120m (the maximum economic piping length can reach 75m), the maximum main pipe length is 300m, and the maximum vertical height difference between indoor and outdoor units can reach 30m. The system can freely tow 1 outdoor unit and up to 9 indoor units (taking 160 as an example), which is more convenient and free to meet the individual needs of users.
Second, how to choose Hitachi compressor
1, when selecting, it is very important that the top CopHitachi IVXmini products in the industry are designed through optimization of each link. Both cooling and heating operations can maintain a high COP value, and the highest COP value can reach the top 4.53 in the industry. The whole series of products have passed the national first-class energy-saving certification, and the comprehensive energy efficiency coefficient (IPLV) has reached the top level in the industry. Hitachi compressor stepless frequency conversion technology Hitachi stepless frequency conversion technology, PFC (power factor correction) combined control technology, control compressor speed.
2. Also, keep the indoor temperature effectively and accurately without consuming more energy. Understand clearly. Unique single-pipe connection technology Compared with traditional and simple multi-pipe products, Hitachi IVXmini products adopt unique single-pipe connection technology, which is characterized by: effectively avoiding the shortcomings of many nodes and easy leakage at the outdoor unit with multi-pipe connection; Save pipeline; Convenient installation and maintenance.
3. Finally, the top axial fan, a quiet life, is the superfluid layer. It's also a good design. Adopt the best fluid distribution design, and reduce the noise by increasing the fan diameter and controlling the speed. The new tuyere (resin type) minimizes the flow friction resistance and makes the air flow smoothly, producing only a small sound. RPIZ-28HRNQ is the quietest thin air duct machine in the industry, with running noise as low as 25dB(A).
Compressor is the core component of our air conditioner. We must know clearly when we choose to use it, so that it can be used smoothly and give us a comfortable feeling.
