1. Product Overview: The "Refrigeration Compressor Performance Test Tr*ning Device" adopts a steam compression refrigeration cycle system, equipped with fully enclosed refrigeration compressors, condensers, evaporators and other real refrigeration system components, and is equipped with intelligent temperature recorders, flow meters, pressure gauges, voltmeters, ammeters and other measuring instruments. Not only can it provide tr*ning on the determination of refrigeration compressor performance parameters, but it can also conduct demonstration tr*ning on the basic principles of refrigeration cycles. It is suitable for teaching and tr*ning of refrigeration major-related courses in vocational colleges. The tr*ning device is also suitable for technical schools, vocational tr*ning schools, vocational education centers, appr*sal stations/institutes, and refrigeration majors such as "Refrigeration Equipment Rep*rer (Primary, Intermediate, Advanced)", "Principles and M*ntenance of Household Refrigeration Equipment", "Operation, Installation and M*ntenance of Refrigeration and Air Conditioning Devices", "Small Refrigeration Devices", and "Small Refrigeration and Air Conditioning Devices".

Learn refrigeration system testing . Test method, design the experimental plan according to the existing experimental conditions, and complete the refrigeration system performance test task.
3. Experimental principle and device:
The compressor, condenser, evaporator, and throttle valve constitute the refrigeration system. The evaporator and condenser are both water-cooled. The refrigeration system working condition is adjusted by the heater to adjust the water temperature of the evaporator inlet and outlet, and the valve is used to adjust the flow of water in and out of the evaporator and condenser. The cooling capacity is the heat taken away by the water in and out of the evaporator, and the heat taken away by the water in and out of the condenser is measured to verify the experiment. Simulate the f*lure phenomenon and data changes of the refrigeration system. The experimental data is displayed in real time through a 5-inch color temperature/pressure monitor, and the experimental data can be saved and printed.
