    • PROBLEM TO BE SOLVED: To provide a method for estimating the temperature of retained water in an airtight space from a picked-up image in place of a thermometer, such as a thermocouple.SOLUTION: A typical configuration of a retained water temperature estimation method relating to this invention is a method for estimating the temperature of retained water 110 in an airtight space. In the method, the temperature of a gas phase of the airtight space is measured (S100), an image in the airtight space is imaged (S102), the diameter of a falling water droplet, a falling velocity of the water droplet and the number of water droplets are calculated from the image, and the mass of the water droplets per unit volume in air is calculated from the diameter of the water droplet, the falling velocity and the number of the droplets (S104), a saturated water vapor content is calculated from the temperature of the gas phase (S106), a total value is calculated by adding a saturated water vapor content to the mass of the water droplets in air (S108), and the temperature of the retained water is estimated so as to make the saturated water vapor content from the retained water coincide with the total value (S110).
    • 要解决的问题:提供一种用于从拾取图像代替诸如热电偶的温度计来估计气密空间中的保留水的温度的方法。解决方案:关于保留水温估计方法的典型配置 本发明是用于估计气密空间中的保留水110的温度的方法。 在该方法中,测定气密空间的气相的温度(S100),成像气密空间中的图像(S102),下降水滴的直径,水滴的下降速度和数量 从图像计算水滴,并且从水滴的直径,下落速度和液滴数量计算空气中每单位体积的水滴的质量(S104),饱和水蒸汽含量为 由气相温度计算(S106),通过向空气中的水滴质量中加入饱和水蒸汽含量来计算总值(S108),并且估计保留水的温度,使得 来自保留水的饱和水蒸汽含量与总值一致(S110)。

    • PROBLEM TO BE SOLVED: To provide a water temperature measurement system capable of measuring seawater temperature even when abnormality is generated in a thermometer for measuring the seawater temperature.SOLUTION: The water temperature measurement system includes: a regular-use intake thermometer 51 and a reserved intake thermometer 52 for measuring water temperature near an intake for taking in water to be supplied to power facilities; a regular-use drainage thermometer 71 for measuring water temperature near a drainage for discharging water heat-exchanged by the power facilities; and a switch SW11 which when a difference of measurement results between the regular-use intake thermometer 51 and the regular-use drainage thermometer 71 is larger than a regulated value, switches connection to any one of a total amount gauge for generating an alarm output, the regular-use intake thermometer 51 and the reserved intake thermometer 52. The regular-use intake thermometer 51 includes a float to which a thermometer is attached and ended to a pipe and a wire for suspending the float from an upper portion. When determining that the wire may be caught based on a measurement result from the regular-use intake thermometer 51, the total amount gauge generates an alarm.
