The invention relates to the technical field of refrigeration equipment, in particular to a quality and flow testing system and method of a refrigerating system. The quality and flow testing system of the refrigerating system comprises the refrigerating system, an evaporator and a throttling device of the refrigerating system are disconnected, an air suction port of the evaporator is connected with a refrigerant supply device, and an exhaust port of the throttling device is communicated with a refrigerant collector. A first adjusting valve is arranged between the evaporator and a compressor of the refrigerating system, and a first pressure detector and a second pressure detector are arranged at two ends of the compressor respectively. Meanwhile, the invention further provides a quality and flow testing method of the refrigerating system for the foregoing testing system. By the above structure and method, quality and flow of the refrigerating system can be accurately and effectively tested by the simple structure.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration system mass flow testing system and testing method. Background technique [0002] At present, the equipment used to test the performance of refrigerators can generally provide temperature data at various points in the system, and some can provide pressure data at suction and discharge positions, but there is no indirect calculation data and direct measurement methods for the mass flow rate of refrigerant. Several types of equipment or instruments for testing the mass flow rate of refrigeration systems are very expensive or bulky. At the same time, however, mass flow data is extremely important for refrigeration engineers. This data is related to the performance and efficiency of the refrigeration system. When designing refrigeration systems in the industry, because this data cannot be obtained, the usual practice is to fix the value, and adjust th...
