A process for the provision of cold - and hot water in a water supply system and drinking water device

摘要

The present invention relates to, inter alia, a process for the cold - and hot water preparation in a water supply system, in particular a drinking water supply system, in which– on at least one tap (z1, z3) ready feed end cold water (kw) by means of a cold water circulation (kwz), is predicted, in which by way of a fresh water connection (3a) fresh water (kw) can be fed, and– at the at least one tap (z1, z3) ready feed end hot water (ww) by means of a warm water circulation (wwz) is kept.According to the invention, provision is made for the cold water circulation (kwz) with the hot water circulation (wwz) in such a way that, in the case of a removal of hot water (ww) at the at least one tap (z1, z3) cold water (kw) from the cold water circulation (kwz) in the warm water circulation (wwz) and at the same time fed fresh water (kw) in the cold water circulation (kwz) from the fresh water connection (3a) is adjusted so that, as a result, the temperature of the in the cold water circulation (kwz) (kw) of the cold water is lowered.According to a further aspect is in a cold water (3b) of a cold water circulation (kwz) an outlet device (8) is provided, by means of the cold water (kw) from the cold water circulation (kwz) is discharged when a measured temperature for in the cold water (3b) located in the cold water (kw) has exceeded a predetermined temperature threshold value.
