 PRODUCTS PRODUCTS Air Conditioner/Refrigerator Refrigeration and Heating Trainer
Refrigeration & Air Conditioning Trainer
Air Conditioner/Refrigerator Refrigeration and Heating Trainer
Order No.66972202

1.   This trainer is developed to meet the training requirements for 'Refrigeration technology', 'Refrigerating fluid machinery', 'home use refrigeration equipment principle and maintenance', 'Cold storage technology', etc.

2.   It integrates air conditioner simulator and refrigerator simulator and adopts real refrigerating unit which is perfect for teaching.

3.   It is configured with two systems, one is air conditioner system and another is comprehensive direct/indirect cooling type refrigerator system. The whole system is actual, tight and integrated, which is composed of air conditioner/refrigerator refrigerating system, electrical control system, fault simulation system and so on.

4.   It can intuitively display the system structure and working principle of heat pump type split air conditioner. The refrigerating cycle system structure and real object of main components can be observed clearly. As equipped with AC voltmeter, AC ammeter, thermometer, vacuum manometer and signal lamps, the working condition of air conditioner and refrigerator is clear at a glance.

5.   Liquid level glass is adopted in pipeline for refrigerant state observation, and fault simulation suite is adopted for troubleshooting.
