814a Ref & AC Control and Fault Trainer

814a Ref & AC Control and Fault Trainer

Designed for single phase operation the demonstration case is divided into two main boards:-

a) Mimic Diagram with Cooling and Heating sections and room temperature and humidity potentiometers.

b) Control board with programmable controller and normal Run/Fault switches and indicator lamps.

The following main functions and components are simulated:-

Refrigeration/Cooling

Heating/Heat Pump

Compressor

Crankcase Heater

High Pressure Switch

Reversing Valve

Condensing Unit

Non return Valve (outdoor use)

Expansion Device (outdoor use)

Reversible Filter drier

Sight Glass (Heating)

Non Return Valve (indoor use)

Expansion Device (indoor use)

Evaporator

Low pressure Switch

Suction Line Accumulator

Defrost Facility

 

Up to 21 faults in cooling and heating modes can be simulated
