Refrigeration compressor purchase
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:
