Hitachi, one of the world's top 500 companies, has strong scientific research strength in many fields such as machinery manufacturing and electronic circuits, and these fields are also the core technology sources of air conditioning products, so it is logical that Hitachi can produce air conditioning equipment with top performance and reliable quality.
 
In recent years, Hitachi has actively integrated into the huge Chinese market and set up a number of production bases in China, while household central air conditioning equipment is mainly produced in Hisense-Hitachi joint venture factory, with a clear division of labor between the two joint venture parties, Hisense is responsible for management and sales, and Hitachi controls production equipment, technology and quality control.
 
The first scroll compressor in the world
 
In 1983, Hitachi succeeded in producing the world's first scroll air conditioning compressor, and single-handedly pushed the technology of air conditioning compressor to the next generation. The central air conditioner has a large number of horses, and the refrigeration load is often much higher than that of the split air conditioner, and the scroll compressor can achieve stable and large displacement compression of the refrigerant because of its unique dynamic and static vortex plate occlusion structure, so the scroll compressor has now become the standard configuration of the central air conditioner above 6P.
 
After the 20-year patent period, Hitachi's scroll compressor has entered the third generation, incorporating "asymmetrical scroll plate" and other research and development achievements, the performance is very strong, the cooling and heating effect is quite excellent, and the stability is first-class, almost no air conditioning "strike" due to compressor failure, in addition to the household central air conditioning market is highly recognized, office buildings and other commercial fields are also favored by it.
 
The pioneer of full DC inverter
 
Whether it is split or central air conditioning, inverter has become more and more one of the hard indicators for consumers to buy, as the pioneer of full DC inverter technology, Hitachi central air conditioning brings users the most direct experience is to run calmly, no cold and hot feeling. Compared with Daikin's high-precision refrigerant control system, the full DC inverter technology can sensitively adjust the motor speed and reduce the operating noise of the indoor unit while controlling the refrigerant flow.
 
In recent years, Hitachi has continuously deepened its leading edge in full DC inverter technology, and launched the latest anti-drift ultra-high-precision DIP-IPM inverter, which adopts PAM PWM dual-mode control, and its frequency output range is as high as 0-230HZ, which is almost double the current mainstream frequency range, and the accuracy level is up to 0.1HZ. When the air conditioner is just turned on, it is connected to PAM control, which uses the characteristics of high speed to quickly cool down, and after cooling, it is transferred to PWM control, and its high-precision characteristics are used to make subtle temperature adjustments, and finally achieve a temperature control effect of ±0.5°C.
 
Flagship series - VAM Honor
 
VAM has always been synonymous with Hitachi's flagship model of household central air conditioning, V is Villa, which means villa, bungalow, etc.; A stands for Advanced, indicating that the series applies Hitachi's highest-end technology; M stands for Multi, that is, multi-linked, commonly known as "one-to-many".
 
VAM series is a new product launched by Hitachi in the home field, the external machine is divided into standard type and full effect type, both of which apply first-class full DC frequency conversion technology, the main difference is that the standard type is equipped with a conventional twin-rotor compressor, suitable for small and medium-sized households, the main engine suffix model FSVN5Q, the cost is 4-80,000; The full-effect type is equipped with Hitachi's top scroll compressor, which is more suitable for duplexes, villas and other house types, and the host suffix model is FSXPN2Q, and the cost is 5-100,000 yuan, and consumers need to pay attention to the distinction.
 
In addition, Hitachi, which claims to attach great importance to the Chinese market, has finally synchronized its user-friendly functions that have long been popularized in Japan on the VAM series, such as its original three-control dual heat exchanger technology, which can achieve independent and high-precision control of temperature and humidity, whether it is a warm or cold rainy day, a suitable temperature rainy day, or a hot and humid sauna day, it can automatically match the temperature and humidity balance scheme, and feel more comfortable and pleasant.
 
In addition, Hitachi's unique lazy cheats "Frozen Cleaning" is also synchronized to the VAM series, frozen cleaning is through rapid refrigeration, so that the surface of the fins in the air conditioner frosts and peels off the dust, and then switches to heating to generate condensate, and finally discharges the dust, although this function has been "tributed" by many domestic air conditioning manufacturers, but Hitachi, as the founder, has the best integration in hardware configuration and algorithm accuracy, and the cleaning ability is second to none.
 
A high-end cost-effective choice
 
Hitachi's mainstream household central air conditioning models also include VAM mini series and EXPRO series, among others. In the domestic household central air conditioning market, Hitachi's market share is second only to Daikin among foreign brands, and the VAM mini series is indispensable. Although with the word "mini", but its host provides more than 6P large capacity optional, to meet the needs of large families, the cost is between 3-80,000, the whole system adopts advanced stepless full DC frequency conversion technology, it should be pointed out that the new VAM mini series has been changed to a lower grade of dual-rotor compressor, the performance has shrunk.
 
The EXPRO series is mainly positioned at the low-end, there is only one fan for the external unit, the heat exchange efficiency decreases significantly, the maximum can be "one drag five", it is generally recommended to buy small families, it is equipped with Hitachi conventional double rotor compressor, as well as stepless full DC frequency conversion technology, the cost is between 25,000-50,000, and the overall cost performance is high.
 
Offline services are in place
 
Hitachi has more than 1,000 specialty stores across the country, offline service capabilities are not bad, and flagship stores have also been opened on e-commerce platforms.
