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: A multi faceted system for simulating free flight, playing games in a free flight mode, and photographing the experience in a manner which permits of the creation of a montage, in which a vertical air column is defined by a variable cylindrical walls, and in which at least a portion of the air column is moving in laminar flow mode.
