Description
This device is specially developed for vocational colleges refrigeration or related professional training device will ReBengShi family air-condition pipeline system directly on the device, intuitive show the structure of variable frequency ReBengShi splits, and main parts of equipment on the flow chart of panel is equipped with digital voltmeter, digital display ammeter, seismic pressure gauge, signal lamp, make whole air conditioning operation condition be clear at a glance, according to the characteristics of frequency conversion ReBengShi splits set up 6 kinds of common faults, to strengthen the students’ condition in ReBengShi splits debugging, fault diagnosis and maintenance, etc. Comprehensive maintenance ability.
Functions and practical training items of the device
* Too much refrigerant failure of refrigeration system;
* Capillary blockage in refrigeration system;
* Condenser outlet of refrigeration system is blocked;
* High pressure and low pressure gas series failure of refrigeration system;
* The return pipe of the refrigeration system is blocked (the failure is cancelled in the heating state);
* Too little refrigerant fault of refrigeration system (the fault is too much refrigerant in the heating state);
Prominent features of the device
1. Use the real heat pump split air conditioner as the teaching, practical training and assessment object, so that students can understand and master the working principle and maintenance skills of the actual air conditioner
2. The detection of air-conditioning system is divided into two parts: temperature and pressure:
1) Inlet temperature and pressure of the condenser;
2) Inlet temperature and pressure of condenser
3) Evaporator inlet temperature and pressure;
4) Inlet and outlet temperatures of the condenser;
5) Air inlet and outlet temperatures of the evaporator;
6) Return air and exhaust air temperature of refrigeration system;
7) Outlet temperature of condenser refrigeration system;
8) Outlet temperature of expansion valve;
3. The teacher edits the test questions in the intelligent assessment system of the teacher’s computer, and sends the edited questions to the student computer of each practice training assessment table through the assessment system. The student computer will generate corresponding fault points on the air conditioning system according to the content of the questions.
4. After the failure point is set in the air conditioning system, students will determine the position of the failure point through the comprehensive analysis of the failure phenomenon and the temperature and pressure numerical changes of each measurement point, and answer the questions through the intelligent evaluation system.
5. The intelligent evaluation system will give corresponding scores according to the right and wrong answers of students, and save the answering process and scores for later inquiry and printing.
6. The method of flow chart and measuring instrument can directly display the position of the measured points of each measuring instrument, so that students can have a more intuitive understanding of the changes of the long-distance data of the air conditioning system.
7. Supporting the corresponding refrigeration teaching software, the software can dynamically demonstrate the working principle of various refrigeration equipment and the working process of the refrigeration system, interactive strong, so that students can easily master the relevant technical knowledge of various refrigeration systems.
