Vapour Compression Refrigeration and Heat Pump Trainer Model RAC 010

Sci-tech Vapour Compression Refrigeration and Heat Pump Trainer Model RAC 010 is designed to provide students with a thorough understanding of various types of systems used in commercial and industrial applications. It permits students to understand the refrigeration cycle, including measurement of pressure, vacuum, flow rate and temperature.

Item Description

It is a mobile type training equipment, frame made of aluminum profile with castor wheel installed. Clear ergonomically mimic diagram consists of refrigeration and heat pump cycle diagram, digital thermometer, voltmeter, ammeter and pressure gauge incorporated.

The unit contains a reversing valve so that the system may be run as a heat pump in addition to operation as a refrigeration system.

Sight glasses at inlet and outlet of evaporator and condenser allows students to monitor changes in refrigerant state. The system components are panel mounted to provide easy access for testing and troubleshooting.

Optional ‘Data Acquisition Software’ & related interface and sensors available.
