Refrigeration cum Heat Pump Trainer MODEL RAC 007
Refrigeration cum Heat Pump Trainer MODEL RAC 007
Sci-tech Refrigeration cum Heat Pump Trainer Model RAC 007 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.
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.
