Abstract (en)

[origin: FR2760078A1] A used fluid passes through an exchange path (1), located in a fluid flow transfer (2), before returning for use (13) at a required temperature (TU2). In the transfer path (2) the exchange path (1) is set between the evaporator (6) and the condenser (8) of a refrigerating circuit (4). The refrigerating circuit (4) is actuated only when the temperature (TA1) of the transfer fluid, consisting for example of ambient air, is unsuitable for properly modifying the used fluid temperature by means of the exchange path (1). The used fluid can be heated by simply reversing the direction of the flow in the transfer path (2). The invention is useful for rearranging exchange paths (1, 6, 8) into a single transfer path (2), for example in a single bundle of tubes arranged in several tube layers of suitably connected tubes.
