Hitachi is the world's second largest industrial chip manufacturer. Together with Intel, it is listed as the world's two major manufacturers of industrial control chip brands. It pioneered turbo compressors in the 1980s and refrigerated the world. The industry has opened a new chapter in the history of air conditioning. Hitachi has its own stepless frequency conversion technology and is the leader in the industry's variable frequency multi-connected air conditioning system. It has obvious energy saving effects and economical air conditioning operation. Hitachi's first two-stage oil separation technology reduces the possibility of air-conditioning pipe blockage and makes air-conditioning operation safe and reliable. However, Hitachi air conditioners are generally more expensive. It is recommended that people who are pursuing the quality of air conditioners consider the Hitachi brand of air conditioners.
Advantages of Hitachi air conditioners:
Cooling effect
The compressor is the heart of the air conditioner. Whether it is cooling or heating, it is inseparable from the important link of the compressor. , all rely on the compressor to run all the time, so I want to know how effective this air conditioner is at cooling? Just look at whether the air conditioner compressor is powerful or not. Hitachi RAS/C-35GVX adopts a new generation of scroll compressor with a symmetrical double pressure chamber structure, which makes the compressor run with less resistance and smoother operation. Compared with the traditional compressor used by its peers, it can run at a higher speed, and the efficiency is improved at the same time. Powerful cooling/heating power, very powerful cooling and fast cooling.
Power consumption
As we all know, the compressor of the air conditioner is running all the time, so while the air conditioner brings us comfortable temperature enjoyment, it also brings us high electricity bills. Hitachi RAS/C-35GVX adopts a new generation of frequency conversion technology, and the indoor unit uses a DC motor. The annual electricity bill is only half of the annual electricity bill of Hitachi's old fixed-speed 2-level 1.5 HP heating and cooling unit 4 years ago. It can also be seen from the above table that Hitachi RAS/C-35GVX has the second smallest cooling power and the smallest heating power. After one year of use, it saves a lot of electricity bills compared to other brands of air conditioners.
Environmental protection and health
Hitachi RAS/C-12MVZ uses a new generation of refrigerant - R104A (composed of hydrogen, fluorine, carbon atoms, without chlorine), which will not damage the ozone layer. Hitachi RAS/C-35GVX is equipped with a stainless steel spray mesh with a smooth surface, making cleaning easier; the mesh is fine, effective in dust filtration, and the Hitachi air conditioner has a one-button cleaning function (in the stopped state, press the stop button on the remote control for three seconds Seconds, the indoor unit of the air conditioner starts automatic cleaning operation (the whole process lasts for thirty minutes), and the air sent out by the air conditioner is healthier.
Noise
Hitachi RAS/C-35GVX adopts a silent design. From the data in the table, the decibel level of Hitachi air conditioners is similar to or even worse than that of domestic air conditioners, but Hitachi makes air conditioners. It was many years ahead of us. It has accumulated a lot of technology in air conditioning and has a lot of black technology. It can control the decibel level when the air conditioner is running within 25 decibels, which is lower than the sound of two people whispering. Don't you think it's awesome? Domestic air conditioners started a little late, and there is a lot of technical gap between them and Hitachi, and they cannot maintain the decibel level at a relatively low level when the air conditioner is running.
Disadvantages of Hitachi air conditioners:
Warranty period
Hitachi is a comprehensive multinational group, Japan's largest electrical manufacturer and a Fortune 500 company, with services and The after-sales service is guaranteed and worthy of the trust of our consumers. Hitachi RAS/C-35GVX adopts nationwide joint warranty service. We can enjoy nationwide warranty service with the invoice. Hitachi has a 3-year warranty for the complete machine and a 5-year warranty for the compressor. However, compared with the warranty period of air conditioners such as Gree, Midea, and Oaks, Hitachi's warranty period is relatively short. The warranty period of the entire machine (except the compressor) is only three years.
Price
Since the important parts of Hitachi air conditioners are imported, plus tariffs, the price of Hitachi RAS/C-35GVX is a bit high, compared to the other three More than twice the price, the price is relatively high.
Summary: The three core technologies of air conditioners - compressor, inverter and controller are all unique to Hitachi and have the best technology in the industry. High-end air conditioners of other brands use Hitachi Compressor, it can be imagined that the performance of Hitachi air conditioners is relatively excellent, but the biggest flaw of Hitachi air conditioners is the high price. It is recommended that users who are pursuing air conditioner quality or have a sufficient budget can choose it.
The following editor selects four popular 1.5 HP inverter air conditioners on the market for comparison and compiles the following table.
What directly affects the above key parameters is the compressor as the core component. Through the above comparison, it is not difficult to see that Hitachi is superior to other brands in terms of heating power, heating capacity, cooling power, etc., and the compressors used by Hitachi air conditioners are all high-efficiency and low-noise compressors developed by itself. Many domestic brands High-end air conditioners all use Hitachi compressors. You can imagine how powerful Hitachi compressors are.
