I. Overview

The "compressor performance test table (electricity heat meter) method)" uses steam compressed refrigeration circulation system, equipped with real parts such as refrigeration compressors, st--nless steel condenser, evaporator and other refrigerators. Instrument, electronic expansion valve, turbine meter, pressure transmitter, voltage, voltage, current, power, composite power, non -performance power, composite powerless power, each viewing power, composite view of power, power viewing power, power viewing power, power viewing power, power viewing power, power viewing power, power viewing power, power viewing, power, power, power, power, power, power, power, power, power, power, power, power, power, and power. Collector. Not only can the performance tr--ning of the performance parameters of the refrigeration compressor can be set up, but also the demonstration tr--ning of the basic principles of the refrigeration cycle can be performed. Teaching tr--ning for professional courses related to vocational colleges.

2. Features

1. The tr--ning device is according to: the test parameter is in line with the performance test method of the performance test method of the GB/T 5773-2016 volume refrigerant compressor. The performance tr--ning method of compressor is established. Through this experiment, the test conditions and testing methods of the refrigeration compressor are familiar with and understood the testing of the refrigeration compressor to enhance the understanding of the refrigeration compressor and the heat issued to offset the refrigeration capacity of the compressor, thereby achieving a balance.

2. In the test, the electric heater group puts the evaporator in a closed cont--ner. The cooling capacity of the compressor is used to determine the refrigeration volume, the refrigeration, and the refrigeration coefficient under the measurement of the standard conditions. Calculation can achieve two types of working conditions: heating and no fever.

3. The power thermal setting has a glass vision, which can observe the liquid level of the second refrigerant.

4. Use 1 refrigeration unit. The condenser is a shell tube water exchange device. The system structure is compact, the layout is reasonable, and the shape is beautiful and generous.

5. There are voltage leakage protection, current leakage protection, overcurrent protection, overload protection, grounding protection, and effective protection of personal and equipment

6. Touch screen and refrigeration system control: Students can use the simulation temperature on the software or touch screen to analyze the working data of the --r conditioner in various temperature states, and design the accumulated data for future practical m--ntenance. Real -time and history, export. convenient
