SIMUREFR TM  is a commercial refrigeration simulator and troubleshooting training system, designed for students and HVAC/R service technicians. The simulator is an invaluable tool for teaching students the basics of commercial refrigeration operation and troubleshooting, as well as improving the service skills of experienced technicians.

SIMUREFR simulates three generic versions of low-temperature and medium- temperature refrigeration systems that a service technician would commonly encounter in the field.  They include:

Pressurestat and thermostat cut-in and differential, box and ambient temperatures, defrost frequency and timeout, and TXV setpoint are all adjustable. Up to 30 different mechanical and electrical faults may be inserted into the simulator, as shown in the Fault Lists below.

Fault List #1  Fault List #2

Eight common refrigerants, including non-CFC/HCFC types, may be selected for the simulated system. An on-screen temperature/pressure chart is available for each refrigerant.  The selectable refrigerants include:

SIMUREFR provides easy-to-use "point-and-click" selection of components, meters, and test points. Temperatures may be displayed in either °F or °C, and pressures in either imperial (psig) or SI/metric (kPa/barg). The following on-screen test instruments and charts are included in the simulator:
