FEATURES

• Teaching methodology using animation and narration explanation voice complete with job sheet and manual equipment.
• Cycle composition: compressor – condenser – receiver – filter dryer – sight glass – solenoid valve – heat exchanger – expansion valve – evaporator – heat exchanger – liquid separator – compressor.
• Hot gas defrost cycle: compressor – solenoid valve – capillary tube – evaporator – heat exchanger – liquid separator – compressor.
• Can be operate on manual or using PLC control system, to control thermal control of pump down, and hot gas defrost.
• Function of refrigeration performance automatic measuring data acquisition equipment and system monitoring program.
• Measure temperature at each of compressor inlet and outlet, condenser inlet and outlet, expansion valve inlet and outlet, evaporator outlet, heat exchanger (gas) inlet and outlet, inside chamber and outside using thermo couples.
• Measure of pressure within the range of -1 bar up to 35 bar at each of compressor inlet and outlet, condenser outlet, expansion valve outlet, and evaporator inlet by pressure sensors.
• Measure of factors: refrigeration effect, compressor work, condensing effect, evaporating latent heat, amount of flash gas at expansion valve outlet, dry rate and humidity at expansion valve outlet, end coefficient of performance (COP), the abstract with temperature and pressure data measured.
• Complete with text book related with refrigeration (theory and troubleshoot) and automatic control experiment (sequence, PLC, IC).
• Windows based automatic measurement system, excel transfer capability RS232 interface.
• Operating performance test of air cooling and cold storage performance test by increasing and decreasing air cooling and storage load performance test for the proper refrigerant charging.
