Which air conditioner is better for Daikin and Mitsubishi Electric?

Which air conditioner is better for Daikin and Mitsubishi Electric? Four major pieces of air conditioner, compressor, condenser, evaporator, throttling device, and finally, fighting for technology, fighting for capital Technically speaking, it is the compressor, heat transfer, P board, fan, motor, function. 1 home machine Compressor: The compressor used by Daikin is a swing compressor, and Mitsubishi Electric uses a rotor compressor. I saw that someone also answered Hitachi's dual rotor compressor. First of all, we have to talk about rotor compressors. Rotor compressors have some shortcomings. First, the rotor and the blades are separated. It is easy to produce wear, noise, leakage and so on. The swing compressor combines the rotor and the blade, as shown in Figure [1], which can solve these problems. The manufacturing process is micron-level, which is difficult. Daikin also has this patent. You may ask, Mitsubishi Electric and Hitachi will not know these problems, of course, they will also propose their solutions. But in essence, it is still difficult to solve the shortcomings of the rotor compressor. Daikin is no match for Mitsubishi Electric's sales of household appliances. A very important reason is that Mitsubishi also has fixed frequency models Daikin and Mitsubishi Electric Air Conditioners are both Japanese-funded brands, and the technical level will not be much different from each other. Each has its own advantages. Daikin is the undisputed overlord in commercial multi-unit air conditioners, and its technical level can also be said to be the most advanced Objectively speaking, both air conditioners are very good. Especially central air conditioning Daikin only makes air conditioners, and Mitsubishi Electric's business includes: heavy power systems, industrial automation, information and communication, electronic components, household electrical appliances and others. As for air conditioners, compressors and inverters are core components. Both Daikin and Mitsubishi use their own compressors. The difference is that the compressors currently produced in China are produced by Suzhou Daikin Compressor Factory, and the compressors of Mitsubishi Electric are produced by Guangzhou Mitsubishi Electric according to different models. Japan Mitsubishi Electric. In terms of frequency converters, Daikin used Mitsubishi Electric frequency converters before, but now uses the brand of Yaskawa Electric, and brushes a Daikin LOGO on the outside. The frequency converter is Mitsubishi Electric's strong point, leading the world in technology. In terms of performance, Daikin has to be cut a lot, because the air conditioner designed by Mitsubishi Electric is to reduce the limit of heating attenuation to 2 degrees, while the Chinese national standard is about 6 to 7 degrees, so Daikin and many other brands are especially Domestic brands are designed in accordance with the national standard, that is to say, they start to decay the heating capacity when the temperature drops below 6 degrees, and Mitsubishi Electric does not start to decay until it is below 2 degrees, and the capabilities are naturally different. In other words, Japanese brand air conditioners are not heated by electricity. Daikin uses assembly line operations in the production process, and Mitsubishi Electric uses robot technology. It is similar to playing somatosensory games during assembly. Every step of the worker's operation is controlled by the computer. For example, a screw is installed, and the computer will prompt you Install the A-type screw at this position. Tightening the screw requires a gun with a torque of 1. At this time, the box of the A screw will pop out, and the gun with a torque of 1 will also jump out. The worker will not take the wrong screw or over-screw the screw. Tight or too loose, one step can be completed before the next operation, which eliminates differences in worker levels. If the funds are limited, and the house is underfloor heating or central heating, it is recommended to buy Daikin low-end machine series, anyway, cooling is no problem, if you want to consider the effect of air conditioning and heating, and there is no heating equipment at home, then it is recommended to buy Mitsubishi Electric, whichever one No matter, Mitsubishi Electric does not develop low-cost package models like Daikin, and selects according to area. If the money budget is sufficient to pursue stable performance and long service life, then Mitsubishi Electric is undoubtedly the first choice. The central air conditioner Daikin is a swing compressor. This is where Daikin has the strongest technical strength. Of course, Daikin also has a split air conditioner, but the compressor is not as good as Mitsubishi Electric's scroll type.
