FIELD: heating.
SUBSTANCE: present invention relates to a method of controlling the maintaining water temperature in the water heater with the heat accumulator controlled by the electronic regulator. The method of controlling the water heater with a heat accumulator in which water heating is carried out by the heating element, controlled by the regulator, which can bring the water temperature to a variable target temperature, and which comprises: defining moment (tONk; t'ONi) of the start of heating to ensure intakes (Pk; Pi) of water comprises the following stages: at short time intervals (δW) all the w intakes are accounted (P1, …, Pi, …, Pw), which moment of start (ti) falls on the specified time window (Δtw) immediately following the current moment of time, and the time window (Δtw) is selected based on the type of water supply system, for which the water heater (1) is designed, and is sufficiently extended to include the moment (ti) of start of all the intakes (Pi), which moments (t'ONi) of the start of imaginary heating presumably precede the moments (t'ON) which correspond to (i-1) preceding intakes (P1, …, Pi-1), at the said moment (ti) of start of intake which falls on the time window (Δtw), the same number of imaginary intakes (P'1, …,P'i, …, P'w) is constructed each of which has the same moment (tw) of start as the start moment of the corresponding real intake (Pi), and the initial temperature (T'set.i) of the imaginary intake determined by adding the initial temperatures (Tset1, Tset2, …, Tset (i-1)) of all water intakes accounted for the time window (Δtw) and preceding the intake itself (Pi), and the corresponding initial temperature (Tset.i) of real intake, on the basis of which each initial temperature (Tset1, Tset2, …, Tset (i-1)) is determined of the optimum temperature (Topt) of discharge according to the formula T'set.i=Tset.i+(Tset1-Topt)+(Tset2-Topt)+…+(Tset(i-1)-Topt), for each of the imaginary intakes (P'1, …, P'i, …, P'w) the moment is calculated (t'ONi) of start of imaginary heating according to the formula t'ONi=ti-(T'set.i-Tm)/VTh, on reaching the earliest of the moments (t'ONi) of start of heating the target temperature (Ttarget) is set at an initial temperature level (T'set.i) of the corresponding imaginary intake (P'i), at that it is understood that the upper limit of the said target temperature (Ttarget) is the maximum set temperature (Tset.max), and to achieve the earliest of the moments (t'ONi) of the start of heating the temperature is maintained (Ttarget) equal to the maintaining temperature (Tstand-by), and the said maintaining temperature (Tstand-by) is the temperature maintained at moments of time remote from the moments of the intake.
EFFECT: invention enables in the planned mode to change with the passage of time the temperature in the water tank.
