Abstract: In a first fluid circulation device, a heat exchanger, a tank that stores a first fluid liquefied by the heat exchanger, a first fluid pump that pumps the first fluid stored in the tank, a heater that heats the first fluid pumped from the first fluid pump, and a first fluid supply unit to which the first fluid is supplied from the heater are connected by a first pipe. A second fluid circulation device includes a cooler that cools a second fluid, causes the second fluid having been cooled by the cooler to circulate through a second pipe, and returns the second fluid to the cooler. The second pipe is connected to the heat exchanger and is connected to the tank and the first fluid pump, and the second fluid cools the first fluid in the heat exchanger, the tank, and the first fluid pump.

Abstract: An air conditioner is provided, including an air flow path, a cooling unit disposed in the air flow path that cools air introduced into the air flow path to condense vapor contained in the air, and a humidification unit that humidifies the air and which includes a storage tank for storing water and a heater for heating water in the storage tank. A discharged-water storage unit is also provided, which stores water discharged from the cooling unit and water discharged from the humidification unit, and an exhaust pipe is connected to the storage tank and configured to discharge water in the storage tank to the discharged-water storage unit. An exhaust valve is disposed midway on the exhaust pipe, and an overflow pipe connects the storage tank and a part of the exhaust pipe on the downstream side of the exhaust valve.

Abstract: A status monitoring apparatus includes information obtaining means to obtain detected information items that are continuously detected; image data generating means to partition the detected information items by frames at predetermined time intervals, and configured to generate, for each frame, two-dimensional image data representing a distribution of detected information items in the frame, with an axis of abscissa being a time axis and an axis of ordinate being an axis showing a value/amount of the detected information items; and status detecting means to perform a machine learning based on the two-dimensional image data generated by the image data generating means to generate a correct label for judging whether the two-dimensional image data show at least a warning sign of failure, and to judge that at least a warning sign of failure has occurred in the detected information items, when the two-dimensional image data corresponding to the correct label are generated.

Abstract: A liquid temperature adjustment apparatus 1 includes: a refrigeration device 10 which includes a refrigeration circuit 16 in which a compressor 11, a condenser 12, a first expansion valve 13, and a first evaporator 14 are connected in this order by a pipe to circulate a heat medium and an injection circuit 17 which branches from a portion downstream of the compressor 11 and upstream of the condenser 12 in the refrigeration circuit 16 and is connected to a portion downstream of the first expansion valve 13 and upstream of the first evaporator 14; and a first liquid supply device 100 which circulates a first liquid. The injection circuit 17 includes a flowrate adjustment valve 17A which adjusts a flowrate of the circulated heat medium. Further, the first liquid circulated by the first liquid supply device 100 is cooled by the first evaporator 14.
