Shallow oil return method of parallel refrigeration compressors

Compressor oil return is one of the key problems in piping design, and it is also a troublesome problem that must be solved; the solubility of refrigerant and lubricating oil should be miscible, slightly soluble, and miscible at high pressure and separate at low pressure. ; The problem of oil return often occurs in the exhaust pipe and return pipe. Today, the analysis is the oil return problem of parallel compressors
