Fluid circulation control for central heating system - uses transverse couplings between parallel circulation tubes to form selectively opened circuits

摘要

The central heating system has a central boiler, solar heating panels etc. radiators for space heating, heat storage devices and heat exchangers. The different elements of the heating system are interconnected via a fluid circulation control for optimum operation of the system. The circulation control has pairs of parallel tubes each connected across the input and output of one of the elements and allowing the distribution pumps and the control valves to be installed as required in each of these tubes. Transverse tubes can be connected between the two tubes of each pair, or between the tubes of different pairs to provide an arbitrary number of circulation circuits. The latter circuits are opened and closed either manually or automatically via a microprocessor control so that the heat distribution is of variable capacity.
