Refrigeration compressor purchase

Refrigeration compressor purchase Compressor selection is the first step in the establishment of a refrigeration system. Choosing a suitable refrigeration compressor can neither have excess power nor insufficient cooling capacity, which can lead to an increase in power consumption. It must be more suitable for the local environment. In this article, the editor will share with you the selection principles of refrigeration compressors.
　　 First: Select the compressor according to the cooling capacity, in general, no backup machine will be set; Second: if you need to choose multiple refrigeration compressors, try to use the same series of compressors;
　　Third: Compressors with different cooling capacity are used together to ensure economical rationality when using peak load or valley;
　　 Fourth: For different refrigeration systems, it is necessary to take into account the possibility of compressor replacement among systems;
　　 Fifth: For a general Freon refrigerant system, when Pk/P0>10, select a bipolar compressor, otherwise use a single-stage compressor. The brand of cold storage refrigeration compressor 　　Here are a few well-known refrigeration compressor brands as a reference:

　　 1. Bitzer, Germany. BITZER refrigeration compressors are used in environmentally friendly air conditioning and refrigeration systems, and are mainly used in high-efficiency energy-saving buildings, units, frozen retail and food processing industries, and transportation industries. Its products occupy a leading position in the refrigeration, transportation and comfort air-conditioning industries. BITZER produces and supplies: semi-hermetic piston compressors, open piston compressors, semi-hermetic screw compressors, fully enclosed screw compressors, scroll compressors, pressure vessels and related after-sales services.
　　 2. US Copeland. Youjia Xiaoqi is an American Copeland refrigeration unit, with Copeland CR hermetic compressor with high efficiency, high reliability and other functions. It is the world's largest compressor research and development center. In China, the two factories located in Suzhou and Shenyang have a total investment of more than 1.5 billion yuan and have served the Chinese market for 12 years.
　　 3. Hitachi. Located in the forefront of the world's top 500 and ranked in the top 10 in the world, it has strong scientific and technological strength in high-tech industries such as machinery manufacturing, integrated circuits, circuit electronics, nuclear energy, and magnetic levitation trains. For a long time, Hitachi's air conditioning system has taken scientific and technological progress and technological leadership as its own responsibility, constantly innovating to meet the changing needs of society.
