About Evaporator Control With Electronic Expansion Valve

EVAPORATOR CONTROL WITH ELECTRONIC EXPANSION VALVE

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.

The refrigeration controller continuously monitors the operation of the components and issues an alarm signal should errors occur. The controller is programmed via a data cable using a programming device. This allows for adjustments of the thermostat function, daytime/night-time operation, the defrosting function, energy saving functions and safety functions. In the simulation software the outside temperature is entered, the refrigerant selected and the door of the freezer opened or closed. In the "time graph" menu, the operating states of the individual components are displayed and the temperature and pressure graphs recorded.

Additional real components, such as expansion valve and pressure and temperature sensors, are used for demonstration purposes and increase the practical relevance.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
