Air Conditioning/Refrigerator Refrigeration and Heating Training System

　　Product name

　　Air conditioning/refrigerator refrigeration and heating training assessment device

　　Model (Type)

　　BF-HY-9920K

　　Feature

　　1. The system integrates simulated air conditioners and simulated refrigerators, and adopts real refrigeration units to meet practical teaching requirements.

　　2. The device is equipped with 2 sets of systems, 1 set of air conditioning system, 1 set of direct cooling/indirect cooling refrigerator integrated system, which can meet the requirements of air conditioning and refrigerator training operation and assessment at the same time

　　3. The whole set of training device integrates the refrigeration system of air conditioner, refrigerator, electrical control system and fault simulation system. The system is real and complete, with clear and compact structure.

　　4. The training device intuitively shows the system structure and working principle of the heat pump split air conditioner, and can clearly see the structure and main components of the refrigeration cycle system. The system is also equipped with pointer type AC voltmeter, pointer type AC ammeter, Digital thermometer, vacuum pressure gauge and signal light make the real-time working status of the entire heat pump split air conditioning system and refrigerator system clear at a glance; in addition, there is a sight glass in the pipeline to observe the refrigerant status; the high-pressure pipeline is red, and the low-pressure pipeline The pipeline is the blue part

　　5. The fault setting can be simulated. Students can analyze the possible causes of the fault according to the process, determine the scope of the fault, and troubleshoot. Conducive to the development of skills appraisal, assessment and training.
