Changes of State in Refrigeration Cycle Model RAC 043
Changes of State in Refrigeration Cycle Model RAC 043
Sci-tech Changes in the State of Refrigeration Cycle Trainer Model RAC 043 is designed to demonstrate working of Vapor Compression Refrigeration Cycle & change of phase of refrigerant during the cycle.
Features
– Designed to demonstrate Change of State of Refrigerant in Compression Refrigeration Cycle.
– Facility to simulate variable Heat load conditions & it effect on performance of Cycle.
– Comprehensive Instrumentation Panel with all necessary measuring instruments.
Item Description
The trainer uses Hermetic Compressor, Condenser, Expansion Device & Evaporator. To visualization of phase change of refrigerant; the condenser & evaporator are shell & coil type with transparent glass shells. The refrigerant flows through the shell & water flows the copper coils. CFC free refrigerant is used in the system & is pre charged in the system.
Instruments to measure Cycle Pressure, Temperatures at different points, Power Consumption, Heater Load are fitted on Instrument panel. Flow of refrigerant & water is measured using Rotameter fitted with calibrated scale. High & Low Pressure cutoff switch & thermostat are provided as safety devices.
The entire setup is mounted on sturdy steel frame made of Mild Steel Tubes & Sheets. The entire frame & panel are powder painted for durability.
Detailed Operation & Maintenance Manual is provided along with the trainer.
