Bench Top Mechanical Heat Pump Trainer

The air-to-water heat pump trainer consists of a compressor, an evaporator with fan, a thermostatic expansion valve and a coaxial coil heat exchanger as condenser.
All components are clearly arranged in the trainer.
For a continuous operation the generated heat is dissipated via an external cooling water connection.
The compressed refrigerant vapour condenses in the outer pipe of the condenser and thereby discharges heat to the water in the inner pipe.
The liquid refrigerant evaporates at low pressure in the finned tube evaporator and thereby absorbs heat from the ambient air.
The hot water circuit consists of a tank, a pump and the condenser as heater.
The cooling water flow rate is set via a valve and measured.
