    Brief Analysis of Hitachi Central Air Conditioner and Daikin

    Brief Analysis of Hitachi Central Air Conditioner and Daikin In the current domestic central air-conditioning market, the central air-conditioning is still doing well with Japanese brands. But among the Japanese brands, we have to say that Hitachi is the brand of Hitachi. At present, most air conditioners use scroll compressors as the power core, and the world's first scroll compressor was manufactured by Hitachi in 1983. The excellent performance of scroll compressors in refrigeration systems Today, after many years, it is still a hot topic of discussion, and Hitachi is always at the forefront of technology. So what are the advantages and disadvantages of Hitachi central air conditioning? Next, give you a brief analysis. Therefore, we compare the Daikin VRV series and Hitachi VAM-mini series with a small difference. When we buy a central air conditioner, we pay special attention to these points: the performance of the compressor, the effect of the inverter, the cost performance, and the market share. The following is a general description of Hitachi and Daikin products from these points. The compressors Daikin and Hitachi are both scroll compressors. The high-end models before 2003 used Hitachi compressors, and the low-end machines used rotor compressors. At present, Hitachi's scroll compressors are manufactured in Hitachi, Taiwan and Hitachi, Japan. The vast majority of Daikin's air conditioners use domestic compressors. The strength is known from this. Because Hitachi VAM-mini uses Hitachi’s patented high-pressure scroll compressor, which uses permanent magnet materials, plus a cluster compressor motor, and the design of the asymmetric scroll structure makes the suction loss and leakage loss greatly reduced, running Efficiency is greatly improved. Therefore, the advantages of small leakage, high efficiency, low noise, small vibration and long life of scroll compressor are reflected in VAM-mini. Inverter in central air conditioning. Hitachi is unique in itself and has the most advanced technology in the industry. The inverters in the Shinkansen inverter locomotives in Japan all use Hitachi products. It can be seen that the reliability of Hitachi inverters is very good. It is said that Daikin has not yet developed and produced inverters by itself. ability. Daikin is the leader in the market share, but according to the information I found, Daikin ranked first in air-conditioning market share in 2016, and Hitachi ranked second, although the market share is leading. But Hitachi is not inferior, and has increased significantly year by year, especially in real estate supporting, and is the only designated air-conditioning brand of China Vanke, China's largest real estate company. Overall, Hitachi Central Air Conditioner is a good choice for consumers who like Japanese air-conditioning brands and pursue air-conditioning quality.
