Abstract
A cooling plant for cooling one or more switch cabinets. According to this invention, a large heat exchanger or several small heat exchangers operating in parallel are housed in a heat exchanger cabinet, wherein an inner space of the heat exchanger cabinet is coupled to a central air-conditioning device supplying cold air to a double bottom by an air inlet in the cabinet bottom and an air outlet of the double bottom. The cold air fed to the heat exchanger cabinet goes through the large heat exchanger or the small heat exchangers and cools the coolant flowing therein. The water supply and the water return of the large heat exchanger or the small heat exchangers are connected to the feed line and the return line of the switch cabinets that are to be cooled. This simple construction makes it possible to easily adapt the efficiency of cooling and the capacity to the variable number of switch cabinets.
