Title: HOT WATER RECIRCULATION SYSTEM
Abstract:
The provision of hot water supply system [1001] is a set of a recirculating mechanism [1002] and a system of the Thermostatic Recirculation Valve [1003] which result to the recirculation of water, pushing the water to be separated into individual networks, to be flowing in circles and be reheated inside the heating source [132]. The provision contains jumpers, a pump [134], non - return valves [133], expansion vessels [135] and sensors [136, 137, 138] and it's being controlled via a control system [139]. The main component is the Thermostatic Recirculation Valve [1115], which bridges the branches of individual subnets, enabling through this connection the water to flow. The thermostatic valve incorporates a thermostat [105] or a bimetallic strip [143] or another thermal expendable system, and restores it to its original position, stopping the recirculation. In addition, another basic layout is a special pump [160], which contributes to the increase of pressure in the water network to overcome not only the pressure of the grid but also the friction.
