The TAR/EV absorption refrigeration training bench is designed for practical analysis of the absorption refrigeration cycle and the study of energy transfer processes. This device allows students to understand the operation of a refrigeration system based on real data and graphs such as log P-1/T and concentration/enthalpy diagrams.
Main system features:
- Steel structure: mobile stand with color display of hydraulic schematic diagram and LED indicators.
- Sealed carbon steel system: consists of a boiler, heat exchanger, evaporator and absorber.
- Refrigerant: water and ammonia solution.
- Heat sources: 12 V electric heaters and LPG burner with pressure regulator and electronic ignition.
- Freezing chamber: transparent structure with two compartments.
- Measuring equipment: electronic thermometers with Pt100 sensors, digital multimeter.
Technical specifications:
- Power supply: 230 V AC, 50 Hz, single-phase (150 VA).
- Dimensions: 130 x 80 x 180 cm.
- Weight: 114 kg.
Curriculum:
- Representation of an absorption refrigeration cycle on a log P-1/T diagram using temperature measurements.
- Transferring data to a concentration/enthalpy diagram and analyzing heat exchange in the boiler, condenser, absorber and evaporator.
- Calculation of the average solution flow rate.
- System efficiency assessment based on boiler temperature.
This stand is suitable for schools, universities and research centers that want to deepen students' understanding of absorption refrigeration systems and their efficiency.
Optional accessories:
- Photovoltaic generator mod. PT/EV: allows the system to be powered by renewable energy.
