Domestic refrigerator compressor ranking, what are the brands of refrigerator compressors

1. Panasonic compressor.

Panasonic's strength in the field of compressors is very mature, and now the refrigerator compressors produced by Wuxi Panasonic and Singapore Panasonic are more common in China. Generally, if there is no Panasonic refrigerator that indicates that it is an original imported compressor, they are all Wuxi Panasonic products.

2. Danfoss compressors.

Danfoss was born in Denmark in 1933 as a Danish multinational industrial manufacturer. Danfoss is known for promoting the application of advanced manufacturing technology and focusing on energy conservation and environmental protection, and is a leading manufacturer and service provider in the fields of refrigeration and air conditioning control, heating and water control, and transmission control.

3. Garcibela.

Founded in 1988, Garcybella is a professional manufacturer of compressors, Garcibella compressors are the specific suppliers of many well-known brands of refrigerators. The export of compressors produced by it ranks first in the domestic industry, and its comprehensive competitiveness has always maintained a leading position in the industry.

Fourth, Zanussi.

As early as the 60s, Zanussi has introduced foreign advanced compressor technology and carried out domestic research and development. In 1987, Zanussi began to introduce the most advanced Zanussi compressor manufacturing technology and production line in Europe, and at the same time began to produce Zanussi brand compressors through the license, which is the earliest refrigeration compressor manufacturer in China.

5. Embraco.

Embraco is a Brazilian brand, is a very large compressor manufacturer brand in Brazil, at present, most of the domestic refrigerators are made by its joint venture company in China - Beijing Embraco Snow Compressor ****.

The compressor is the heart of the refrigerator, and once the compressor stops running, the air conditioner stops working, which shows the importance of the compressor. The operating principle of the compressor is to pressurize the refrigerant to increase its pressure, and then evaporate it in the evaporator, and the refrigerant after evaporation and condensation returns to the compressor, and then pressurizes and evaporates. Repeat the cycle.

It can be seen that the importance of a good compressor for the refrigerator is self-evident.

Compressors can be divided into:

1. Piston compressor.

The work of the piston compressor is completed by the continuous change of the working volume of the cylinder, the valve and the piston that reciprocates in the cylinder.

2. Screw compressor.

Screw compressor is a kind of volumetric gas compression machinery with working volume for rotary motion.

3. Centrifugal compressor.

The centrifugal compressor, also known as the "vortex compressor", is a multi-stage type, which can make the gas obtain higher pressure, larger processing capacity and higher efficiency.

4. Linear compressor.

A compressor that uses a rotary electric motor to bring in energy.

The quality of the compressor can be judged from the following aspects:

1. Look at the state of the runtime. A good compressor runs with less noise, smooth sound and no noise.

2. Look at the energy efficiency ratio of the compressor. That is, the input power, the output power. The energy efficiency ratio is a comprehensive indicator that reflects the conversion of cooling capacity per unit of input power during the operation of the air conditioner. The greater the energy efficiency ratio of the refrigerator, the more electricity is saved when the cooling is equal.

3. Look at its service life. Compressors are divided into two types: domestic and imported, and relatively speaking, the service life of imported compressors is relatively long. Generally, the life span of domestic products is 5-7 years, and that of imported products is 10-15 years.

4. Look at the brand. A big brand is a guarantee of quality. At present, the compressors of Siemens and Haier refrigerators are the best on the market.

Siemens uses Panasonic compressors, and Haier uses Brazil's Embraco. The compressor used in each brand of refrigerator is not single, and the compressor used by many brands and models is also different.

Common compressor brands on the market are:

1.Embraco.

Embraco is a compressor manufacturer from Brazil, and most refrigerators in China currently use compressors manufactured by its joint venture company in China, Beijing Embraco Snow Compressor.

2.Zanussi.

Zanussi compressor is the original Italian brand, which was acquired by Electrolux. The Zanusi compressor for domestic refrigerators is produced by Zanusi Electric Machinery Tianjin Compressor.

3.Panasonic compressor.

Panasonic's strength in compressors, at present, the most common refrigerator compressors in China are produced by Wuxi Panasonic or Singapore Panasonic, and Panasonic refrigerators that are generally not indicated as original imported compressors are all Wuxi Panasonic products.

4.Garcibela.

Garcibella is a domestic compressor brand, the company was founded in 1988, located in Jiaxing City, Zhejiang Province.

5.Highly Headquartered in Shanghai, Highly acquired Qingdao Sanyo Electric Company in 2007 and later renamed Qingdao Highly Electric Company, which mainly produces refrigerator compressors.

Most of the compressors are produced in Taizhou, Jiangsu, which is independent technology, and the compressors produced by it are mainly used in LG refrigerators, and there are also a few ** to domestic manufacturers.

7.Toshiba. Domestic sales of refrigerator products are less used, mainly Japanese brand refrigerators, there are also a few domestic brands in use, the compressors produced by them are all using frequency conversion technology, mainly made in Japan.

8.Hitachi. Hitachi's compressor technology is relatively strong, but it is relatively rare in the domestic market.

Jaguar (Xiamen East Asia Machinery), a well-known brand of Xiamen East Asia Machinery, whose products are mainly permanent magnet screw machine series, was selected as the first place in the "Energy Efficiency Star" list of the Ministry of Industry and Information Technology of the People's Republic of China.

Atlas Copco China, headquartered in Shanghai, mainly focuses on oil-free air compressors and oil-injected screw air compressors.

Ingersoll Rand (referred to as IR), IR's air compressors are mainly centrifugal air compressors.

Suzhou Sullair mainly focuses on stationary screw compressors, mobile screw compressors and oil-free compressors.

Zhejiang Kaishan, an enterprise engaged in air compressors for more than 60 years, its main products are screw sail family air compressors, refrigerant compressors, etc.

Fusheng Industry is mainly based on low-pressure screw machines and two-stage compression.

Hanbell Precision Machinery, the main product is refrigeration compressors.

Bolaite State or Atlas is an acquired brand.

Red Wuhuan, the products include vertical compressors, mobile compressors, air-cooled reciprocating spike pressing, high shrinking machines, etc.

Hitachi China's products include oil-free screw air compressors, oil-free screw air compressors, etc.

The refrigerator compressor brands are as follows: Embraco, Zanussi.

The working principle of the solid expansion temperature switch is to use the difference in the length of different solids after heating to produce displacement, so that the contact action and output the temperature switching signal.

A temperature switch is made of bimetal sheets (brass sheets stacked on top of indium steel), which bend when heated because the linear expansion coefficient of the brass sheet is greater than that of indium steel. When the specified temperature is reached, the free end of the bimetal sheet (the moving contact of the temperature switch generates sufficient displacement, disconnects from the fixed static contact, and sends a switching signal.

Key features:

Input and output power, coefficient of performance, refrigeration capacity, starting current, operating current, rated voltage, frequency, cylinder volume, noise, etc. The performance of a compressor is measured, mainly from three aspects: weight, efficiency and noise.

According to Chinese standards, its safety performance inspection is carried out according to the specified items. The main items are electrical strength, leakage current, locked-rotor, and overload operation test.

The performance inspection of the compressor of the air conditioner is carried out in accordance with the provisions of GB5773 2004. Type tests must be carried out when there are major changes that may affect the performance of the product in the finalization and production of the product, when the continuous production is completed for one year or reproduction after more than one year, and when the factory inspection results are quite different from the type test.
