Heat Pump For Cooling And Heating Operation

Refrigeration circuit with compressor, condenser (heat exchanger with fan), 2 evaporators with fan (refrigeration and freezing stage)
Air-to-water heat pump for cooling or heating operation
Displays for temperature, pressure, flow rate and power consumption of the compressor.
Different operating modes selectable via solenoid valves
Glycol-water circuit with tank, pump and coaxial coil heat exchanger
1 thermostatic expansion valve each for all heat exchangers and evaporators
1 additional evaporation pressure controller and 1 capillary tube for the refrigeration stage evaporator
Coaxial coil heat exchanger and heat exchanger with fan can both be used as condenser or evaporator in the refrigeration circuit.
