On-line evaluation device and method for refrigerant / lubricant pair on compressor performance

Abstract

The application discloses a kind of refrigerant / lubricating oil pair compressor performance online evaluation device and method.The application can accurately control the mixing ratio of lubricating oil and refrigerant, synchronously online obtain the mutual solubility of lubricating oil and refrigerant, fluid thermophysical property parameters such as liquid phase density and viscosity, simulate various compressor actual operation conditions by flexibly adjusting temperature, pressure, flow and load conditions;And real-time monitoring temperature, pressure, flow, power and other key operating parameters under each simulated condition of compressor, so as to comprehensively and accurately evaluate the influence of lubricating oil and refrigerant interaction on compressor operating efficiency, stability and service life, provide scientific basis and technical guidance for compressor performance optimization.
