Japanese brand air conditioners mainly include the following brands: Mitsubishi, Daikin, Toshiba and Hitachi.
Mitsubishi is divided into Mitsubishi Heavy Industries and mitsubishi electric. In fact, the main body of Mitsubishi Group is Mitsubishi Heavy Industries, and mitsubishi electric is only the electronics research institute under the Nagasaki Shipyard of Mitsubishi Group. However, because of Mitsubishi's trademark authorization, it has been expanding its market as Mitsubishi for decades, which is a niche, which Mitsubishi Group did not expect in those years. However, the trademark authorization of this company has not been revoked, because only home appliances have little influence on the entire Mitsubishi Group. Mitsubishi Heavy Industries is the real product of Mitsubishi Group. In the 1990s, users of splitters imported by Mitsubishi Heavy Industries had the most say in their quality reputation. In recent years, the central air-conditioning market of Mitsubishi Heavy Industries has not been established because of the decline of Haier's market. However, after 2009, Mitsubishi Heavy Industries has independently produced its own products and operated its own market, which has little to do with Haier. Moreover, the product production standards are completely in accordance with Japanese JIS industrial standards, and the global products are synchronized, which greatly improves the product quality, far from being comparable to Mitsubishi Heavy Industries Haier. (So friends who want to buy Mitsubishi air conditioners must distinguish between Mitsubishi Heavy Industries, mitsubishi electric and Mitsubishi Heavy Industries Haier. )
Daikin is known as a wholly-owned enterprise in China (in fact, it is a joint venture with Shanghai Sewing Machine Factory). It is the only air-conditioning enterprise in the world that integrates air-conditioning equipment production and refrigerant production, and only makes air-conditioning related products. Before 12, Daikin's domestic standard was produced according to China GB, but the actual materials and workmanship were really good. However, after 12, Daikin became more and more lax in the promotion of new products in order to seize the Gree market in China, refit equipment, reduce production costs, quality and reputation, such as Daikin's multifunctional VRV system, which is known as super energy saving. Daikin, a high-end product integrating domestic hot water, was pushed by manufacturers after listing, hoping to change the market structure of central air conditioning. But in fact, in just one year, it has been reported all over the country that the energy consumption of this product is extremely high, and the 22-day electricity bill for a user with 260 square meters of air conditioning area in Chengdu is as high as 7,000 yuan. After that, the manufacturer will not force the sale of this product.
To tell the truth, Toshiba is not familiar with it, but there is a saying in the Japanese air-conditioning industry that "technology looks at Mitsubishi, marketing looks at Daikin, and line control looks at Toshiba", and the quality should be good.
Hitachi only invented the scroll compressor, but the most advanced compressor is the 3D scroll compressor developed by Mitsubishi Heavy Industries. Hitachi's quality is average, but the price is really cheap, which is similar to that of domestic Gree.
