SUPERMARKET REFRIGERATION SIMULATOR

SIMUMKT ®


Mechanical Section


Electrical Section



SIMUMKT TM  simulates a typical parallel-type multi-evaporator supermarket refrigeration system. Normally, a parallel system contains many display cases and walk-in coolers, but for simplicity, SIMUMKT contains just three display cases. One case is low-temperature with electric defrost, the others are medium-temperature with off-cycle defrost. Two 3-phase semi-hermetic compressors, with capacity cycling, are included.

Six common refrigerants may be selected for the simulated system. An on-screen temperature/pressure chart is available for each refrigerant.  The selectable refrigerants include:


Animated mechanical and electrical schematic diagrams of the simulated refrigeration system are provided in "real-time". The mechanical diagrams show refrigerant flow and the liquid, vapor, liquid/vapor, and superheated vapor states of the refrigerant. Also, the liquid level in the receiver is shown. In the electrical ladder diagrams, the controls and switch contacts constantly change state as the system operates. Providing a means of visually tracing the refrigerant and current flow during system operation, makes it much easier for the trainee to understand how the system is supposed to work.

Up to 30 commonly encountered mechanical and electrical faults may be selected, as shown in the Fault List below.

Setpoints for the EPR valves and TXVs can be adjusted for each case, as well as the compressor-cycling control and defrost settings. Case and ambient temperatures are adjustable, and continuously updated and displayed on the screen. All temperature and pressure values can be set and displayed in either imperial or metric.

Pressure-temperature charts for the refrigerants, specifications, and an electrical nomenclature are available on-screen. In addition, the trainee can "zoom" into the system to visually inspect various components, including dirty or iced-up coils, and liquid and compressor oil level sight glasses.

SIMUMKT provides easy-to-use "point-and-click" selection of meters and test points, which are saved to an Instrument Log to monitor the users' troubleshooting skill. Temperatures may be displayed in either Fahrenheit (F) or Celsius (C), and pressures may be displayed in either imperial (psig) or metric (kPa/barg). The on-screen test instruments include:
