    • PROBLEM TO BE SOLVED: To keep an air-fuel ratio even in a transient time of control when a target rotating speed of a fan is changed, in controlling the air-fuel ratio of a gas burner in which an amount of supply air is controlled by controlling a rotating speed of the fan.SOLUTION: A gas pressure supplied to a gas burner 120 is controlled on the basis of an opening of a gas proportional valve 200, and an amount of air supplied to the gas burner 120 is controlled on the basis of a rotating speed of a combustion fan 160. A command gas pressure for controlling the opening of the gas proportional valve 200 is determined by correcting an ideal gas pressure to achieve a prescribed air fuel ratio to the amount of air on the basis of the detected rotating speed of the combustion fan 160, according to a deviation between a final target gas pressure corresponding to a target heat generation amount and the ideal gas pressure in the gas burner 120.
    • 要解决的问题:为了在风扇的目标转速改变时即使在瞬时控制时间内保持空燃比,在控制供给空气量被控制的气体燃烧器的空燃比 通过控制风扇的转速。解决方案:基于气体比例阀200的开口来控制供应到气体燃烧器120的气体压力,并且将供应到气体燃烧器120的空气量控制在 燃烧风扇160的旋转速度的基础。用于控制气体比例阀200的打开的指令气体压力通过校正理想气体压力来确定基于空气的空气量与空气量的比例 根据对应于目标发热量的最终目标气体压力与气体燃烧器120中的理想气体压力之间的偏差来检测燃烧风扇160的转速。

    • PROBLEM TO BE SOLVED: To provide a hot water supply system capable of filling a bathtub with hot water to a set water level even if a part of water heaters is out of hot water supply operation by pouring hot water from remaining normal water heaters, in filling the bathtub with hot water by simultaneously pouring hot water to one bathtub from a plurality of the water heaters.SOLUTION: A system controller 8 is provided with a hot water filling information transmitting section 82, and an available water heater determining section 83 for determining the number of normal water heaters capable of performing hot water pouring operation at this time. A set water level, the number of water heaters in a new operation, and the number of normal water heaters are transmitted to individual controllers 20 of the water heaters as the normal water heaters from the hot water filling information transmitting section 82, a target hot water pouring amount calculating section 202 makes correction by multiplying a value of an average bathtub cross-sectional area used in the calculation of a target hot water pouring amount by (number of water heaters in test operation/number of normal water heaters), and a target hot water pouring amount per one water heater is calculated on the basis of the average bathtub cross-sectional area after the correction and the set water level information to pour hot water.
    • 要解决的问题:为了提供一种热水供应系统,即使一部分热水器通过从剩余的普通热水器中浇注热水而不能进行热水供给,也能够将热水的浴缸填充到设定的水位, 通过同时从多个热水器将热水浇注到一个浴缸中,用热水填充浴缸。解决方案:系统控制器8设置有热水填充信息发送部分82和可用的热水器确定部分83,用于确定 此时能够进行热水倾倒操作的普通热水器的数量。 设定的水位,新操作中的热水器的数量和正常的热水器的数量作为来自热水填充信息发送部分82的普通热水器的热水器的个人控制器20传送到目标热 浇注量计算部202通过将计算目标热水倾倒量所使用的平均浴盆横截面积的值乘以(试验操作中的热水器数量/正常热水器数量)和 根据校正后的平均浴缸横截面积和设定的水位信息来计算每个热水器的目标热水倾倒量。
