Bench Top Mechanical Heat Pump Trainer
Product Code : EL-RAACLE-10785
Quick Answer:
The Bench Top Mechanical Heat Pump Trainer is an air-to-water heat pump unit whose main components -- a compressor, an evaporator with fan, a thermostatic expansion valve, and a coaxial coil heat exchanger as condenser -- are clearly arranged for continuous operation via an external cooling water connection. Compressed refrigerant vapour condenses in the outer pipe of the condenser and discharges heat to water in the inner pipe, while liquid refrigerant evaporates at low pressure in the finned tube evaporator and absorbs heat from the ambient air. A hot water circuit made up of a tank, a pump, and the condenser as heater delivers the heated water, with the cooling water flow rate set via a valve and measured.
Overview:
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, with all components clearly arranged in the trainer. For 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, while 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, and the cooling water flow rate is set via a valve and measured.
