    摘要: A device that can accurately detect clogging of a filter and that has a simple structure is provided. A device for measuring clogging of a filter in an air conditioner (2) having a blower (30) that blows gas (40), (42) through a duct (10) and a filter (20) that is provided in the duct (10) and filters dust floating in the gas, comprises a device (26) for measuring a sound pressure that is provided in the duct (10), a data processor (70) that extracts data on the sound pressure at a specific frequency from the data on the sound pressure that have been measured by means of the device (26) for measuring a sound pressure, and an estimating device (70) that estimates clogging of the filter based on the data on the sound pressure at the specific frequency that have been extracted by means of the data processor (70).

    摘要: An object of the present invention is to provide: an algae water concentration system that efficiently concentrates algae water in a culture pond into algae water containing algae having a desired size, with a simple structure and at low cost; and a method for operating the same. A cultured algae water concentration system 100 comprises: an algae water supply unit 17 that has an algae water supply container 18 that stores algae water sent from the culture pond therein, and a supply container outlet port 19 through which the algae water is taken out from the algae water supply container; and an algae water concentration unit that has a concentration container 1 for receiving and concentrating the algae water from the algae water supply unit, a filter 3 which divides the concentration container into upper and lower spaces and does not pass algae having a predetermined size or larger therethrough, a vibration device 5 that vibrates the filter in an out-of-plane direction, a concentration container algae water inlet port 7 which takes in the algae water to the concentration container and is arranged below the filter of the concentration container, a concentrated algae water outlet port 9 that is arranged below the filter of the concentration container and takes out algae water therethrough that has been concentrated in the concentration container, and a filtered water discharge port 8 that is arranged above the filter of the concentration container and discharges filtered water having passed through the filter.
