DE2027546C3 - Arrangement for the water supply of a high-rise building - Google Patents

Description

Due to the heat exchangers, there is indeed a slight temperature drop between the individual circulation loops one, but this temperature drop per heat exchanger is only a few degrees Celsius. In any case there is enough warm water available everywhere, and it is when water is withdrawn after a while the water at its original fearful temperature fed to the tap. To ensure a cycle within the individual loops, Circulation pumps 148 and 153 are provided.

F i g. 3 shows a view of a pressure reducing valve, which is about the same size as the inspection stations in the known water supply arrangements. This is made possible by the arrangement according to the invention only two capacitors, 224 and 225 available , ind, so that there is enough space for the remaining parts.

In Fig. 3 is a shut-off valve in the cold water line 201 217 is used, which can be opened if the provided pressure reducing valve 219 fails should. Shut-off valves 216 and 221 can be used in the event of a failure of the pressure reducing valve 219 be locked.

A shut-off valve 218 is also inserted into the hot water line 202, which has the same open- * ■. "·« ^{T. "S .. AI} £ ^1T s; ii! 2ÄS _l i ^ ii""·
