First, use Daikin:

1, Daikin's series of products have been completely localized, and the machine materials and assembly and manufacturing processes can't be compared with before, and the quality has declined seriously, resulting in Daikin's high repair rate; Hitachi's high-end model is an assembly machine, the compressor is made in Taiwan Province Province, and the important parts of the internal and external machines are imported from Japan. Meanwhile, Japan's import rate is relatively low. (Interested customers can go to the construction site or Dajindian to see the prototype. How is the quality? I believe you have a steelyard in your heart. )

2. Daikin's heating effect is insufficient (this fact is recognized by the whole HVAC industry and decoration industry, and Daikin's dealers also admit that floor heating is needed in winter); Hitachi's cooling and heating effect is no problem (under normal installation), minus-10 degrees, the outlet temperature is above 50 degrees, and the indoor constant temperature is about 28 degrees.

3. The noise of Daikin is on the high side of 25 decibels, and the return air is 30 decibels after installation. Hitachi 2 1 dB has the lowest practical effect in the industry, and the sound is very low and light (2 1 dB is the lowest refrigeration capacity in indoor unit and low wind mode).

4. Daikin internal machine comes standard with non-condensing lift pump; Hitachi internal machine is equipped with high-lift condensate lift pump (90cm lift).

Second, with mitsubishi electric:

1. mitsubishi electric has few models, large machine volume, thickness of 20 cm and depth of 70cm；; Hitachi has many models, with a thickness of 19.2 cm and a depth of 44.7 cm, and its internal machine is smaller.

2. The noise in mitsubishi electric is too high (louder than Daikin and Hitachi in actual use), and dealers have repeatedly reported to manufacturers that the output of central air conditioners in mitsubishi electric is much less than that of wall-mounted machines, and the market share is low, which has not attracted the attention of manufacturers and has not been improved).

Mitsubishi Ling Yao series manifold connection is a transitional product between Shang Ling series (multi-control) and Ling Rui series (manifold), which leads to pipeline waste, internal mechanical efficiency attenuation, large aperture and many holes; Ling Rui series is the most mature, newest and most expensive product series in mitsubishi electric, and Hitachi uses bifurcated pipes for connection.

4. mitsubishi electric Shang Ling and Ling Yao series are produced in Shanghai, and some Ling Rui series compressors are imported from Thailand. 5. mitsubishi electric Shang Ling and Ling Yao series adopt the third-generation scroll low-pressure chamber compressor, Ling Rui series adopts the high-pressure chamber compressor, and Hitachi third-generation compressors are all high-pressure chambers. (Low pressure cavity increases energy consumption and hidden danger)

6. The actual performance of mitsubishi electric Shang Ling series 5B 120 machines is very unstable, and dealers at all levels of 20 12 have suspended sales.

(Analyze and compare the connection modes from Shang Ling series multi-control and Ling Yao series branch boxes to Ling Rui series branch pipes; Or from Shang Ling Ling Yao series low-pressure cavity compressor to Ling Rui series high-pressure cavity compressor; It can be seen that the product development of central air conditioning in mitsubishi electric is immature in the early stage) (Note: Shang Ling and Ling Yao series equipment have no certificates).

Third, with Mitsubishi Heavy Industries:

1, Mitsubishi heavy industries KX6 series 4-6 foreign compressors are the second generation, and Hitachi high-end models are the third generation.

2. The compressor of Mitsubishi Heavy Industries is imported from Thailand, and the high-end model of Hitachi compressor is produced in Taiwan Province Province, and the mid-range model is produced in Guangzhou.

3. Mitsubishi Heavy Industries Suzhou is short of dealers, its marketing network is unstable (Mitsubishi Heavy Industries has become warm and cold, its home source is warm and cold, and its Kunshan store in tianxiang environment has closed down one after another), and its after-sales service is extremely weak; Comparatively speaking, Hitachi's market in Suzhou is more mature.

Fourth, with Toshiba:

1, Toshiba's indoor unit has a depth of 64.5 cm (the ceiling width of a wardrobe 60 cm away from the door of a bedroom should be at least 80 cm) and a thickness of 2 1 cm, while Hitachi's has a depth of 44.7 cm and a thickness of19.2cm.. It is the narrowest and thinnest brand in the joint venture brand, and the smaller ceiling is more beautiful and generous.

2. Toshiba's high-end compressor is the second generation, and Hitachi is the third generation scroll compressor, which adopts internal secondary oil separation technology.

3. Toshiba's internal machines are made in China, and the external machines are produced in Guangzhou, Hangzhou, Malaysia and the Philippines.

4. Toshiba's internal machine comes standard with condensate-free lift pump, and Hitachi's mid-range and high-end models come standard with condensate lift pump.

Remarks: 1. As we all know, Hitachi, Daikin and Mitsubishi are all joint ventures, but the partners are different, such as Hitachi and Hisense, Daikin and Zhuhai Gree, Mitsubishi and Shanghai Electric, Mitsubishi Heavy Industries and Haier, Dongmei, General Fujitsu and Wuxi Little Swan.

2. Colleagues of individual brands use the relationship between Hitachi and Hisense to attack and discredit Hitachi, saying that Hitachi is made by Hisense and Hisense sells dog meat under the banner of Hitachi. I believe that customers who have their own analysis and discrimination ability will not believe this irresponsible practice of reversing black and white when the owners don't understand the market and products.

Remind every customer that all brands of central air conditioners sold in Suzhou are not imported or 80% or 90% are imported from Japan. Even at present, there are no brands of compressors imported from Japan, and most of them are produced in Southeast Asian countries, Taiwan Province Province and Chinese mainland.

At present, manufacturers of Toshiba Carrier, Mitsubishi Heavy Industries and General Fujitsu are promoting the concept of full import, hoping that Suzhou customers will be vigilant.

In addition to central air conditioning, other products in the domestic market also have similar cost events.

For example:

L Da Vinci imported home, domestic OEM, pure import, originated in Dongguan, Dongguan production.

Italian Capulet brand furniture, known as "original import", is actually processed and produced by a small factory in Dongguan. There are brands in Italy, and those bought for 30 thousand sell for 300 thousand. Da Vinci's home made a huge profit of 10 times, but it challenged the IQ of all consumers.

Shanghai Furniture Industry Association said in an interview that many domestic furniture manufacturers have the problem of reusing a customs declaration form. For example, after importing some products originating in Italy, the same products are produced in domestic factories, mixed with imported products, and the customs declaration certificate is reused. In fact, the customs declaration certificate is only valid for a certain batch of products and cannot be valid for a long time.

L Meikemeijia responded to import fraud: import was counted through customs declaration in the bonded area.

For a long time, Meikemeijia has been regarded as "IKEA" in China by many people, but he stole the concept of product ownership and origin. No matter where the country of origin is, as long as the product is declared in the bonded area, it is regarded as an imported product. This statement of Meikemeijia is obviously untenable. As far as the incident itself is concerned, we have seen too many contradictions in Meikemeijia: the origin of Chinese and English labels is inconsistent, the origin and origin are confused, the Chinese name of customs declaration products is inconsistent with the standard version, and solid wood furniture is promised, but it is a solid wood framework ... The various explanations of the merchants are unbelievable.

Real imported furniture can provide two things, one is the certificate of origin and the other is the price tag. However, Meikemeijia does not conform to the norms in these two aspects.

Two years ago, Leonardo da Vinci put on a mask of foreign brands to deceive consumers, and the furniture industry collectively faced a crisis of confidence. Two years later, the exposure of Meikemeijia once again reflected the confusion of various standards in the furniture industry. At the same time, imported furniture has to go through the barriers of industry and commerce, quality inspection and customs, which also exposes many loopholes in China's regulatory system. It doesn't matter whether the goods are imported or made in China. Whether the bottom line of business ethics is observed or not and whether the goods are genuine or not is the basis for determining the long-term development of enterprises.
