ABSTRACT:
Unit for distribution and/or collection of cold and/or of heat, including: (a) a main exchanger (1) of heat between a refrigerant fluid (2, 21, 22) and a heat transfer fluid (3); (b) a means for producing cold with a means for heat exchange with the heat transfer fluid; (c) a closed main circuit (3) for continuous free circulation of the heat transfer fluid; (d) at least one heat transfer fluid drawing loop (7 to 11); characterized in that the flow cross-section of the main circuit (3), the maximum refrigerating power of the means for producing cold, Pmax, expressed in W, and the main heat exchanger (1) are sized relative to one another in order to satisfy, in operation, approximately the relationship: P.sub.Max =f.sub.m .times.c.times..DELTA.T, in which: f.sub.m is the mass flow rate of the heat transfer fluid, expressed in kg/s; c is the mass heat of the heat transfer fluid, in liquid form, expressed in J/kg/.degree.K.; .DELTA.T is the difference in temperature of the heat transfer fluid between the exit and the entry of the main exchanger (1).
