Evaporator control with electronic expansion valve Deluxe

The control of refrigeration units such as chiller cabinets, refrigerated display cases and freezers is a key topic in commercial refrigeration. The control aims at safeguarding a high level of food quality with simultaneous energy-efficient operation.

• experimental unit from the GUNT practical series for the training of mechatronics engineers for refrigeration
• investigation and programming of an industrial refrigeration controller in the example of a freezer
• simulation of the freezer by way of software
• schematic on the front panel with lamps to indicate the operating states of the actuators
• programming of the refrigeration controller using a programming device
• simulated freezer with compressor, electronic expansion valve, fan, electric defrost heater for the evaporator, frame heating, pressure and temperature sensors
• real freezer components for demonstration purposes: 1 electronic expansion valve, 1 pressure sensor, 2 temperature sensor
• GUNT software for data acquisition via USB under Windows 11
