A table top refrigeration system is used to investigate energy balance at compressor, condenser and evaporator.
Both the condenser and evaporator used water cooled heat exchangers. Instruments are provided for measurement of temperatures, pressures and cooling water flow rates. The system requires outside water supply.
- Familiarization with refrigeration cycle and components.
- p-h diagram.
- Energy balances at evaporator and condenser.
- Overall heat transfer coefficients for evaporator and condenser.
- Effects of load variation.
