SIMUAIR TM  simulates two generic versions of residential and light-commercial air conditioning systems, using either R-22 or R-410A refrigerant. These systems include a packaged unit with a capillary tube and PSC motor circuit, and a split-system with a thermostatic expansion valve (TXV) and CSR motor circuit.

Animated mechanical and electrical schematic diagrams of the simulated system are provided in "real-time". The mechanical diagram shows refrigerant flow, as well as the liquid, vapor, liquid/vapor, and superheated vapor states of the refrigerant. In the electrical diagram, the controls and switch contacts constantly change state as the system operates.

Pressure-temperature charts, performance charts, specifications, and an electrical nomenclature, are available on-screen. The trainee can "zoom" into the system to visually inspect various components, including dirt or ice on coils, and a dirty air filter. He can also "listen" to the compressor as it starts and runs (normal or abnormal).

Up to 20 different mechanical and electrical faults may be inserted into the simulator, as shown in the Fault List below.

Fault List

SIMUAIR 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:

SIMUAIR provides testing and troubleshooting of components and devices commonly found in actual air conditioning systems, including the following:

Compressor Condenser coil Evaporator coil
