FIELD: heating.SUBSTANCE: method and device for control of hot water supply temperature mode are proposed. The proposed method consists in measurement of hot water temperature Tand its maintenance at the specified level of hot water temperature T. In order to obtain hot water, water from return line with volume Vis mixed in a mixing chamber with volume Vwith water from supply line with volume Vin the ratio of V/V=(T-T)/(T-T)-1, where V+V=V. Before water is supplied from the supply line to the mixing chamber, current value of hot water volumetric flow rate Vis fixed as initial value V. Water is supplied from the supply line with volume Vto the mixing chamber in the form of a pulse till condition V-V=Vis met; after that, water supply from the supply line with volume Vto the mixing chamber is stopped and water from the return line with volume Vis supplied to the mixing chamber. A device implementing the above method includes a supply line, a switch, a mixing chamber, a water temperature measuring device, a return line, a check valve and a flow metre.EFFECT: improvement of a method.2 cl, 1 dwg |
