Refrigeration Training Unit Manufacturer India

The Refrigeration Training Unit is a self-contained bench-top trainer for studying the complete vapour compression refrigeration cycle. It provides hands-on experience with all four thermodynamic processes, compression, condensation, expansion, and evaporation, with full instrumentation for measuring pressures, temperatures, and power input at each state point.

Technical Specifications

• Refrigerant: R-134a (HFC, zero ozone depletion potential, eco-friendly)
• Compressor: Hermetically sealed reciprocating type, 1/4 HP rated
• Condenser: Air-cooled finned-tube type with axial fan
• Evaporator: Plate-type heat exchanger for high heat transfer efficiency
• Expansion device: Thermostatic expansion valve (TXV)
• Temperature measurement: 8-point Pt-100 RTD sensors with digital multi-channel indicator
• Pressure measurement: Compound gauge (suction side) and HP gauge (discharge side)
• Power measurement: Digital wattmeter for compressor input power
• Cooling capacity: 400 to 600 W nominal at design conditions
• Power supply: 230V AC, 50 Hz, single phase
• Frame: Powder-coated MS frame with locking castors

Experiments Covered

• Plot and analyse the p-h (Mollier) diagram of the vapour compression cycle
• Calculate Coefficient of Performance (COP) at varying evaporator temperatures
• Determine refrigerating effect and heat rejected at condenser
• Compare actual COP with theoretical Carnot COP
• Calculate volumetric efficiency of the compressor
• Study effect of condenser and evaporator temperatures on system performance
