ET 915 HSI training system refrigeration and air conditioning technology, base unit

GUNT ET 915 HSI

The HSI Training System provides basic experiments on the operation of refrigeration and air conditioning systems by combining the base unit (ET 915) with various models.

It features a condensing unit consisting of a compressor, condenser, and receiver.

The system is connected to the model via refrigerant hoses, and the model is securely attached to the ET 915 using fasteners.

A manometer for refrigerant with a temperature scale is included, and the refrigerant mass flow rate is precisely calculated via GUNT software.

The system uses refrigerant R513A with a GWP of 631, and the control is handled via solenoid valves and software.

The GUNT software allows for system operation, data acquisition, and educational functions.
