Abstract: The present invention relates to an apparatus including: firstly, —a cold production unit (U), having a line for the flow of a coolant (BC); —means for compressing (1), decompressing (4), and evaporating (5) said coolant; and —an air condenser (2) and a main water condenser (CEP). Said facility also includes an auxiliary water flow device that has a first water reception vessel and a second water reception vessel (20, 30). Said auxiliary device defines at least one so-called “water heating” or “water-based calorie removal” path, leading from the first vessel to the second vessel and including at least one main section (65) for removing calories via water and capable of engaging with a main section (7) for exchanging heat with the coolant in the main water condenser (CEP). Said auxiliary device also defines a second so-called “water cooling” path, leading from the second vessel to the first vessel and including at least one water cooling section (82, 92) in a heat exchanger (ECA, EVS).
