摘要： PURPOSE:To eliminate a limit of an ice storage amount by a height of a removal time by dropping ice/water slurry from a space of an upper part of a water surface of a heat storage tank into water. CONSTITUTION:Water supplied from a water intake tube 4 at a bottom of a heat storage tank 1 is fed to a subcooler 2 through a water circulating pump 5 and a preheater 6. The water fed to the subcooler 2 is cooled to a subcooling range of about -2 deg.C at an outlet of the subcooler, and discharged. The discharged subcooled water is released from a subcooled state via a subcooling removal pipe 3, thereby generating shervetlike ice/water slurry. The generated slurry is supplied to the tank 1 from above the water via a tube 8 disposed on the water of the tank 1. Thus, since the transfer tube 8 is disposed spatially independently from the tank 1, feeding of the slurry can be always stably conducted, and an ice storage amount is not limited by a height of the pipe 3.

摘要： PURPOSE: To prevent the hunting operation by so controlling the number of bypass valves and blowers as not to lower the cooling water temperature at the time of unstable temperature of the water immediately after a refrigerator is started, and so controlling the number of the blowers as to approach the value of the cooling tower outlet temperature to the target value after the stabilization. CONSTITUTION: When the cooling water temperature if unstable immediately after a refrigerator 1 is started, a sequence controller 15 automatically controls a bypass valve 11, thereby preventing the excess temperature drop of the cooling water of the refrigerator 1. After transferring to the number control of the blowers A, B, C, the number of the blowers A, B, C is so controlled as to approach the allowable lower limit temperature value of the water of the refrigerator 1 to the target value. Thus, when the atmospheric temperature is low, the tower control for reaching the target value is conducted, while when the atmospheric temperature is high, the water temperature can be set lower than prior art.

摘要： PURPOSE:To improve humidification efficiency, by a method wherein a means, feeding water, is situated to the upper surface of a porous block body, a means, draining surplus water falling through the porous block body, is provided, and air to be processed is caused to pass in the direction of the thickness of the porous block body. CONSTITUTION:A portion where lateral corrugation of a lateral corrugated strip sheet 1 makes linear contact with longitudinal corrugation of a longitudinal corrugated strip sheet 2 is joined with a flat strip sheet 3 to form a sandwitched plywood 4 which is provided on the one surface with a lateral corrugation and on the other surface with longitudinal corrugation. The plywoods are laminated together in a state to arrange them longitudinally in the same direction to form a porous block body 5. Water is dropped on the upper surface of the lamination porous block body through a water feed header 10 in which a number of water feed ports 11 are formed, and air to be processed is forced to pass in the direction of the thickness of the porous block body. In which case, since air passing through the porous block body as the air is agitated is excellently heat-exchanged with water and performs change of a phase, high humidification efficiency can be produced by means of a minimum pass liquid amount. Further, surplus water is received by a drain pan 13 located below the porous block body 5 for drainage.
