Characteristics of Hitachi Central Air Conditioning System
1. patented scroll compressor technology. As early as 1983, Hitachi invented the world's first scroll air conditioner compressor and obtained a patent; In 2003, Hitachi introduced a new type of high-pressure cavity scroll compressor with internal oil function for the first time in the industry, which further improved the efficiency and reliability of the compressor and effectively prolonged the service life of the air-conditioning host.
2. Hitachi stepless frequency conversion technology, Hitachi household central air conditioning compressor can realize stepless frequency conversion-the working efficiency can be continuously and accurately adjusted according to the change of system capacity, with obvious energy-saving effect, economical operation and natural and comfortable indoor environment.
3. Initiated two-stage oil separation technology. Simply put, the refrigerant from the compressor is separated by two-stage oil, so that very little refrigerant oil enters the refrigeration cycle, thus ensuring the refrigerant oil for lubricating the compressor most reliably, and at the same time reducing the possibility of pipeline blockage, making the system run safely and reliably.
4. Compared with the original AC motor, the new DC motor and outdoor fan motor can realize more efficient and energy-saving operation. The outdoor fan can be adjusted at 16 level according to the change of ambient temperature, with finer speed regulation and more comfortable enjoyment.
5. Intelligent controller In terms of control, users can choose limited remote controller, wireless remote controller and seven-day timer to control your central air conditioner in the most convenient and arbitrary way.
6. Smart home control system, Hitachi Central Air Conditioning has a wide range of functions, including one-button mode scene setting, control of up to 16 indoor units, display of start/stop, temperature, wind speed, mode and other states, "child lock" function, prevention of misoperation, wireless interconnection, real-time monitoring and fault self-checking in places covered by WIFI.
Selection method of Hitachi central air conditioning
1, pay attention to the applicability of central air conditioning. Different rooms have different central air conditioners. Only according to the actual housing situation can we choose the appropriate central air conditioning. Specifically: choose the model according to the area and orientation of the house: first consider the area and orientation of the house to see if there are large glass windows, so as to calculate the maximum simultaneous use coefficient of the air conditioner. Generally speaking, in the ordinary home environment, the cooling capacity required for actual use is often not the sum of the cooling capacity of all rooms, but lower than the latter, and the former only needs to reach about 60% to 70% of the latter. This can save investment and avoid unnecessary waste.
2. Pay attention to the quality index of central air conditioning. People choose home central air conditioning, to a great extent, in order to improve the quality of life and improve home comfort. Therefore, comfort has become a problem that has to be considered when choosing home central air conditioning. Generally, comfort is considered from two aspects: temperature adjustment and static sound. First, there should be no sudden cooling or uneven temperature in the room, and second, the noise should not be too loud when the indoor machine is running.
3. It is recommended to choose professional brand products. At present, there are many brands and models of home central air conditioners, which dazzle consumers. It is best to choose a professional brand with excellent quality when shopping. Because the central air-conditioning market has just started, many manufacturers flock in, and it is inevitable that the good and the bad are mixed. Moreover, central air conditioning is a high threshold industry, and it is impossible to survive forever without certain technical strength. Therefore, central air-conditioning must choose well-known brands, and don't be greedy and suffer big losses.
4. Pay attention to products and services Compared with ordinary split air conditioners, home central air conditioners are actually a "semi-finished product" because they have to cooperate with interior decoration. The service of home central air conditioning includes not only after-sales service, but also pre-sales consultation, scheme design, installation and construction. It can be said that the design, installation and construction are as important as the host equipment to make a home central air conditioning system run normally. Therefore, when purchasing home central air conditioners, users must choose enterprises with good service and good reputation to protect their own interests.
Central air conditioning is very important to every family. I believe that choosing Hitachi Central Air Conditioning will not let everyone down. The above is the characteristics and purchasing methods of Hitachi central air conditioning introduced by Bian Xiao today, which ends here.
