Heat Pump With Pump Down Control - Engineering Lab Training Systems
With the air-to-water heat pump ET 102 the ambient heat of the air is used to heat water.
The heat pump circuit 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.
compressed refrigerant steam 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.
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.
