Intelligent Central Air Conditioning Training Equipment

Intelligent Central Air Conditioning Training Equipment

I. Product Overview:
This equipment incorporates new technologies in the refrigeration field, such as data acquisition and monitoring technology in automated control systems.

II. Functional Features:
1. This equipment uses a PLC and data acquisition module as control devices. The panel is equipped with intelligent digital display instruments to monitor the system's various operating states in real time. It also features real-time monitoring capabilities, reflecting the system's operating status via computer, such as instrument displays, the water circulation system's operation, and the supply and return air system's status.
2. This equipment miniaturizes the central air conditioning system while ensuring the integrity and rationality of the entire system. The entire experimental setup can demonstrate summer cooling cycles and winter heating cycles.
3. The system is equipped with various parameter display instruments that show the operating status of each unit and the inlet and outlet water temperatures of the evaporator, condenser, cooling tower, and simulated boiler, facilitating students' observation and understanding of parameter changes and system operation.
4. The experimental platform also incorporates additional auxiliary equipment, enabling it to generate 18 possible malfunctions that might occur during actual operation, facilitating students' understanding of the malfunction phenomena and troubleshooting.
5. The system uses imported American compressors, condensers, evaporators, filters, liquid receivers, expansion valves, and charging valves, among other air conditioning unit components;
