Fluid/fluid heat exchanger for e.g. waste water pipeline in single family house, has control device for controlling flow of fluid in upstream circuit according to temperature of fluid at inlet of upstream circuit
Fluid/fluid heat exchanger for e.g. waste water pipeline in single family house, has control device for controlling flow of fluid in upstream circuit according to temperature of fluid at inlet of upstream circuit
The heat exchanger has an upstream circuit (10) for circulating fluid in an upstream manner, and a downstream circuit (20) for circulating fluid in a downstream manner. The upstream circuit and the downstream circuit are arranged in a structurally overlapping manner so as to allow energy transfer of the upstream fluid toward the downstream fluid. A control device controls flow of fluid in the upstream circuit according to temperature of the fluid at an inlet of the upstream circuit.
