Advantages and disadvantages of Hitachi central air conditioning

Advantages and disadvantages of Hitachi central air conditioning Hitachi Central Air Conditioning has always been at the forefront of air-conditioning technology, advocating the development and transformation of air-conditioning technology with the height of giants. Advantages: 1. Patented scroll compressor technology, as early as 1983, Hitachi invented the world's first scroll-type air-conditioning compressor and has a patent; and in 2003, Hitachi launched the industry's first internal oil separation function The new high-pressure cavity scroll compressor further improves the efficiency and reliability of the compressor and effectively increases the service life of the air-conditioning host. 2. Hitachi stepless frequency conversion technology, the operation of Hitachi household central air conditioning compressor can achieve stepless frequency conversion-the working efficiency can be adjusted continuously and accurately freely according to the change of system capacity, with obvious energy saving effect, economic operation, natural indoor environment Advantages such as comfort. 3. The first two-stage oil separation technology, in simple terms, the refrigerant coming out of the compressor undergoes two-stage oil separation so that there is very little refrigeration oil entering the refrigeration cycle, so that the refrigeration oil that lubricates the compressor is most reliably guaranteed and reduced The possibility of pipeline clogging makes the system safe and reliable. Output energy, intelligently control the angle of the wind guide blades, and gentle air supply to maintain the slightest temperature fluctuations in the best state. There is no vigorous blowing, only gentle refreshment and intimate warmth. 4. Energy-saving and healthy, first: Hitachi home central air-conditioning system can be operated individually, most of the time it is operated under partial compliance, while the outdoor unit can intelligently adjust the ability to output according to the operating status of the indoor unit. More prominent. Second: Hitachi's domestic central air conditioner uses a high-efficiency R410A environmentally friendly refrigerant that does not damage the earth's ozone layer and is non-toxic to the human body. At the same time, the materials used can meet the EU environmental standards. Third: Hitachi indoor unit has two options of activated carbon filter and double-layer activated carbon filter, in which activated carbon has a high-efficiency adsorption function, can be used for air purification, remove volatile organic compounds, formaldehyde, benzene, ammonia and air pollutants , Always keep the air in the room fresh and comfortable. Disadvantages: Hitachi Central Air Conditioner entered China very late, ten years later than Daikin Central Air Conditioning! This is also due to the fact that Daikin Central Air Conditioner could not survive in Japan and entered China early for development. After entering late, the market seized is naturally small, and the market share of Hitachi central air conditioning's multi-line (home improvement) is only one-third of that of Daikin central air conditioning. Its sales network in China is not perfect, and many places simply cannot find dealers to provide services. Fortunately, Hitachi has accumulated a good sense of service throughout the year. Wherever it can be served, Hitachi's installation and after-sales can be well supported.
