Cold water machine has a level of energy regulation control method, a simple temperature controller to control the operation of each level, advanced with a program controller.
Large industrial cold water machine the host configuration is often with a refrigeration compressor with energy unloading mechanism or many sets of compressor are adopted, the refrigeration compressor or energy unloading mechanism or no unloading mechanism of energy, this case with refrigeration compressor cylinder unloading, or change in operation of refrigerating compressor stations or both energy adjustment method of combining the implementation level.
