Heating system controlling method, involves supplying entire water flow to parallel connection of bypass and heat exchanger, and passing flow to exchanger, when flow rate from heat sink is larger than flow rate through heat exchanger

摘要

The method involves arranging a pump (4) between a heat source (141) and a heat sink (142). Feed and return lines (10, 11) are connected via a bypass (144) with adjustable response threshold. An entire water flow rate is drawn in the return line (11) from the heat sink by the pump, is supplied to a parallel connection of the bypass, which is designed as an over flow valve (9), and the heat exchanger, and is passed over the heat exchanger, when a flow rate from the heat sink is larger than a flow rate through the heat exchanger. An independent claim is also included for a heating system comprising a heat exchanger.
