Refrigeration And Air Conditioning Training System (DL TMAC11)

MAIN CHARACTERISTICS

• The trainer combines air conditioning system, refrigerating system and electronical control system.
• The trainer is based on a real domestic heat pump type air conditioner and a real domestic refrigerator.
• The air conditioner can be controlled by remote controller.
• Working temperatures, pressures and electrical values can be directly read from meters for working principle understanding.

It clearly the refrigerator inner components layout and refrigerating cycle system structure; It demonstrates the operating principle of the refrigerator and a heat pump type air conditioner; in includes schematic diagram of control system and relative test points; sight glass in the pipeline is used to observe refrigerant status; HV pipeline is marked with red, while LV pipeline with blue, relative components are all labelled.

• It includes a connection area for electrical control circuit of outdoor unit for students’ hands-on ability training.
• It includes fault introduction system.
