HSI Training System Refrigeration and Air Conditioning Technology

The base unit is designed to be extended into a complete refrigeration circuit by connecting suitable refrigeration and air-conditioning models. The main components include a compressor, condenser, receiver, and the necessary electrical and communication systems. The models are mounted onto the base unit and connected hydraulically using refrigerant hoses and electrically using cables.

Self-sealing couplings help minimize refrigerant loss. All components are clearly arranged and easily visible, allowing their operation to be monitored effectively. The integrated hardware/software system enables convenient execution and analysis of experiments.

The experimental unit can be connected to a PC through an Ethernet interface. The software provides system operation, data acquisition and educational functions. Explanatory texts and illustrations support understanding of the theoretical principles. Additional exercises can also be created using the integrated authoring system.

Temperatures and pressures within the system are recorded by sensors and dynamically displayed in the software. The system provides accurate refrigerant condition data, allowing the refrigerant mass flow rate to be calculated precisely.

Manufactured by Atico Export with a focus on precision, durability and consistent performance for technical education and practical training applications.
