RE-COOLING DEVICE FOR A REFRIGERATION SYSTEM, A REFRIGERATION SYSTEM EQUIPPED THEREWITH, AND A METHOD FOR CONTROLLING A RE-COOLING DEVICE

Abstract: a re-cooling device for a refrigeration system, preferably for an industrial process or an industrial machine, comprising a cooling water circuit () connected or to be connected to a heat exchanger () of a compression refrigeration machine (chiller) () and/or a free-cooling heat exchanger (), a first re-cooling module (), which is connected to the cooling water circuit () and is preferably arranged or to be arranged outside a building envelope in order to be able to dissipate heat to the environment, a second re-cooling module (), which is preferably arranged or to be arranged inside a building envelope in order to be able to dissipate heat to the interior of the building, the second re-cooling module () being connected to the cooling water circuit () via a changeover valve () in such a way that a cooling medium can flow through it selectively, and a control system which is designed to open and close the changeover valve () of the second re-cooling module () as a function of a predetermined outside temperature and/or a predetermined time of year to provide heating support for the interior of the building and raise an efficiency ratio.
