Heat pump

Teaching model of a compressor-operated heat pump on the demonstration board with a manometer indicator in both high and low pressure parts for measurement of refrigerant circulation. Can be used as an air/water or water/water heat pump. For this reason e.g. also suitable for implementing a solar power unit or a roof energy collector model in combination with the solar collector (389 50). Protected against incorrect use by a thermostatically controlled expansion valve and by a pressure monitor in the high pressure part.
With evapourating apparatus and liquefier in helical form and corresponding water containers in different colours for the representation of the two different heat reservoirs. Includes two clamps for thermometers, tubing and work foil on the refrigerant circulation.
