Which brand of central air conditioner is good? My house is more than 10,000 square meters, and I re

Since you have to buy such an expensive house, you have to buy a joint venture brand of central air conditioning, and it is still not possible to produce domestic compressors in all aspects. Daikin, Hitachi, Mitsubishi Heavy Industries, LG and many more.

Which is better, Hitachi central air conditioning or Daikin central air conditioning???

1. Quality: Today's Daikin is no longer the Daikin of a few years ago, and the machine has been fully localized; With the increase in production, the quality declined sharply; The quality of individual parts is worrisome in the outsourcing of small workshops.

Second, the core technology of the compressor: Daikin used Hitachi scroll-shaped fluid mechanical compressors (scroll compressors) from 83 to 03 years, and it was not until the expiration of Hitachi's patented technology in 03 that Daikin began to independently produce its own compressors in Xi'an.

At this time, in the same year, Hitachi has invented and mastered a higher patented technology, on the basis of the manufacture of the third generation scroll compressor, the innovative development of the compressor internal secondary oil separation technology (lubricating the refrigeration oil of the compressor is the most reliable guarantee, the system operation is safe and reliable, the technology can greatly extend the service life of the compressor), the technology has also applied for a patent, the current market sales of Daikin air conditioning does not use this technology.

Some owners of the HVAC industry know that Hitachi's quietness and energy saving are definitely better than those of Mitsubishi Electric (in terms of heating, the installation is not as good as the problem, Mitsubishi and Hitachi are about the same, and the heating can be guaranteed);

Hitachi's compressors, inverters, and control systems represent the most high-end technology in the entire industry, Hitachi products are updated very quickly, Hitachi Group is a technology-oriented enterprise, and the third-generation scroll compressor is not developed by Mitsubishi Electric or Daikin, but Hitachi.

Hitachi's stepless inverter technology, trinity technology, and automatic intelligent dehumidification technology are unique in the entire industry.

Central air conditioning 3 points of products, 7 points of installation, different installation and construction levels directly determine the later stage of the machine refrigeration, heating, noise, service life and the probability of pouring the top, at the same time the installation materials are also very important, the same quotation on the market of the same material, the construction materials and quotation materials do not match a lot, especially small companies, secondary and tertiary agents. Therefore, you need to choose carefully when buying central air conditioning.

Among the domestic central air conditioners, Haier and Gree are good. Central air conditioning is installed in three parts and seven products, so good installation and service are also very important, and buying Haier should be a good choice.

I use Haier's, a tow and a duct machine, and I installed a 2P in the living room, 6000 yuan, and I feel pretty good at present, and the attitude of the installation master is also very good.

People who understand air conditioning must know that Hitachi's central air conditioning is not worse than Mitsubishi Electric, Hitachi's cost performance is relatively high, and the quality of central air conditioning products of Daikin, Toshiba, Panasonic and other brands cannot be compared.
