REFRIGERATION EDUCATIONAL UNIT
Educational unit for the study of the complete refrigeration cycle, mounting/dismantling exercises, vacuum, charging and system trimming. The system includes every refrigeration component normally employed in a commercial/industrial refrigeration unit. Condenser, drier, receiver, oil separator, drier, compressor are be bench top mounted and clearly disposed in order to show every circuit, which is painted with different colours in order to identify the suction line, the compression line, the oil return line. The standard instrumentation includes four temperature gauges, one electronic temperature control system, high pressure gauge, low pressure gauge, pressure safety control, fault simulation valves. A more sophisticated instrument system is available with the possibility of upgrade the unit up to a complete Computer control system with experiment processing software. A large insulated refrigerating cell is in the lower part of the unit and inside it is mounted a forced air evaporator with thermal load resistors for thermal load simulation, controlled by a switch on the control board. The unit can be mounted on pivoted wheel for an easy laboratory installation. A simple connection to the main electricity and the system is in order to work.
