18 kinds of air-conditioning compressor competition! Whose compressor is the strongest refrigeration heart

Is Hitachi air-conditioning compressor Toshiba brand "I obviously bought a Hitachi air conditioner. It was discovered that the air conditioner used a Toshiba compressor during maintenance." A few days ago, some media reported this complaint about Hitachi air conditioners. Therefore, many consumers questioned the difference between the case and the internal machine brand: the purchase clearly identified a certain brand, why did you change the brand of the contents inside without telling it? Is there any difference between the products of the two brands? What if the after-sales service is not guaranteed? 　　Reporter survey found that internal parts and shells are not the same brand of products are very common, purchase should pay attention. 　　 Toshiba compressor for Hitachi air-conditioning According to media reports, Ms. Gong purchased a Hitachi air conditioner in January 2005. Due to maintenance and disassembly of the machine, it was discovered that the brand of the compressor turned out to be Toshiba, and the Hitachi factory stated that it could not replace other brands and models. If the compressor needs to be repaired, only one such Toshiba compressor can be equipped. 　　Ms. Gong said that when buying this Hitachi air conditioner, the salesperson specially emphasized that the inner core of the air conditioner is the Hitachi compressor produced by the original factory. Unexpectedly, this time because the air conditioner could not be cooled, she opened the machine for maintenance, and she knew she had been cheated. Shanghai Hitachi Maintenance Department said that manufacturers consider the same quality compressors, and Toshiba's relatively low cost. Therefore, some models of air conditioners do not use original compressors. For this situation, the factory regrets and says that it will be in the future. Explain to customers during sales. Regarding Ms. Gong’s request for replacement of Hitachi’s compressors, a person in the maintenance department said that because of matching reasons, it was not possible to replace other types of compressors, and she could only help her with a new Toshiba compressor. 　　 "Core change" products are not uncommon 　　 "The compressor of the air conditioner is inconsistent with the brand of the air conditioner itself. This situation is relatively common in China." Lu Jianguo, Minister of Testing Department of China Household Electrical Appliances Quality Research Institute said. The reason is very simple. It is impossible for a production enterprise to produce all parts and accessories. This situation is also very common in the automotive industry. Just like many brands of cars use engines of other brands, it is rare Some enterprises are engaged in the production of products ranging from small screws to large products. Lu Jianguo said: "Internal parts (including compressors) and housings are not the same brand, it is indeed very common, not every air-conditioning production plant produces compressors. According to the requirements of national standards, the air-conditioning quality table certification report writes The parts and entities are the same." Subsequently, the reporter contacted Mr. Yao from the customer service center of Shanghai Hitachi Household Appliances Co. by phone. He said that Hitachi Compressor Manufacturing Company and Hitachi Air Conditioning Company were not the same company, and the two were independent. Products from Hitachi Compressor Enterprises must be installed. 　　According to Mr. Yao, there are currently five compressor manufacturers at home and abroad. Hitachi Compressor Enterprise is one of the brands that manufacture compressors. Manufacturers of air conditioners of other brands can choose Hitachi compressors, and Hitachi air conditioners can also choose compressors of other brands according to their own needs. The choice is mainly based on the test of the effect of the air conditioner model and the compressor. "The manufacturer will choose the best performance product to manufacture the finished product according to the experimental effect." 　　 After-sales service to identify the whole machine brand Lu Jianguo particularly reminds consumers to pay attention to the requirements of national standards when buying air conditioners. It is not important that the brand of the compressor is different from the brand of the whole machine. From a safety point of view, it is not allowed to replace and leave the factory when replacing the compressor. Inconsistent products. From the perspective of warranty, consumers should identify the brand of the whole machine. If there is a quality problem, they should contact the after-sales service department of the whole machine brand. If the manufacturer does not cooperate, they can protect themselves through the Consumer Rights Protection Law Rights. Mr. Yao also said that there is no quality problem of after-sales service in the complaint. Hitachi's air-conditioning products are in compliance with the national three guarantees regulations. There is a problem with the compressor installed. For manufacturers, even if they are not using their own brand of compressor, after-sales service will be handled in strict accordance with relevant regulations and technical requirements.
