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); andat 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 network (106) by means of the
heat pump device (132), and wherein the networks (104, 106) have different temperature levels.The present invention furthermore relates to a method for generating heating and
cooling power in a treatment
plant (102) for workpieces, in particular a vehicle body
paint shop (103).
