Closed circuit for handling hot water, e.g. for district heating, increases or decreases flow if water temperature is outside given range

摘要

The circuit (1) includes a first means (2, 19) for regulating the flow through the circuit depending on the measured temperature. This first means is designed to increase flow if the measured temperature is below a minimum value, and to decrease flow if the measured temperature is above a maximum value. Hot water is made to flow in one direction (a) using a pump (2). An inlet device (3) is used to supply cold water to the circuit and downstream of this device is a heat source (4) for heating the water in the circuit. At least one outlet device (11) for hot water is located downstream from the heat source. A first sensor device (17, 18) measures water temperature downstream from the outlet device and upstream from the inlet device. An Independent claim is also included for a hot water handling method using this circuit.
