Bench Top Mechanical Heat Pump Trainer
SKU: HI MRA-003

The "HANSA" 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.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. For a continuous operation the generated heat is dissipated via an external cooling water connection. The cooling water flow rate is set via a valve and measured.Bench Top Mechanical Heat Pump TrainerFEATURESDesign and operation of an air-to-water heat pumpRepresentation of the thermodynamic cycle in the log p-h diagramEnergy balancesDetermination of important characteristic variablesCompressor pressure ratioIdeal coefficient of performanceReal coefficient of performanceDependence of the real coefficient of performance on the temperature difference (air-to-water)Operating behavior under loadSPECIFICATION:CompressorCapacity: 372W at 7,2/32?CCoaxial coil heat exchanger (condenser)Refrigerant content: 0,55LWater content: 0,3LFinned tube evaporatorTransfer area: approx. 0,175m2PumpMax.
