Abstract: The present invention relates to a system (100) for generating heating and cooling power in a treatment plant (102) for workpieces, in particular a vehicle body paint shop (103), wherein the system (100) comprises the following: at least one cold water network (104) for supplying consumer processes (146) with cold water, which has at least one cold water storage device (110) for compensating process load peaks and/or at least one cold water network heat transfer device (112, 154, 158) for recovering heat from consumer processes (146); at least one warm water network (106) for supplying consumer processes (146) with warm water, which has at least one warm water storage device (120) for compensating process load peaks and/or at least one warm water network heat transfer device (122, 166) for recovering heat from consumer processes (146); and at least one heat pump device, in particular at least one first heat pump device (132), wherein the cold water network (104) is connected to the at least one warm water

Abstract: In order to provide a method for the conditioning of air which is implementable in a reliable and energy-efficient manner, it is proposed that the method comprise the following: determining the actual values of at least two parameters of an inlet air stream of a conditioning system in which the air is to be conditioned; selecting an operating state of the conditioning system on the basis of a model by means of which a plurality of possible actual values of the at least two parameters is linked to operating states of the conditioning system; setting the conditioning system into the selected operating state so that an output air stream of the conditioning system is produced in which the actual values of the at least two parameters lie within preset target value ranges.
