ABSTRACT:
A heat exchanger containing two heat-exchange fluids flowing in countercurrent irrespective of the direction of heat exchange selected.
In the specific case of a compressor heat pump, the exchangers 2 and 3 are provided with calibrated non-return valves 1A, 1B, 4A, 4B and 1C, 1D, 4C, 4D respectively to reverse the direction of flow of the fluid flowing in the heat pump for winter or summer operation. These valves automatically assume the required position when the four-way valve 5 of the compressor is actuated.
Application to compressor heat pumps.
