ARRANGEMENTS FOR THE PURPOSE OF THE WHOLE TEMPERATURE OF A WATER CIRCULATION CREDIT IN A CERTAIN WORLD, BASED DOWN TO THE CREDIT, OF THE CLOSED TAPPING SYSTEM

摘要

A fluid supply system for supplying a fluid draw-off such as for example domestic showers includes a fluid blending valve discharging blended liquid into a recirculation pipeline delivering to the draw-off and returning to a cold inlet of the blending valve, liquid recirculation occurring when the draw-off is closed, and a pump is preferably provided to ensure satisfactory recirculation. At least a portion of the recycled liquid is fed to a heat exchanger. To ensure that the temperature of the recycled liquid is maintained at a desired value, which is particularly desirable in the case of a shower installation where excess temperature can be physically dangerous, an additional thermostatic control valve is provided responsive to the recycled liquid temperature and operatively associated with the heat exchanger to maintain the recycled liquid temperature.
