In a control device, an instruction acquirer acquires an instruction to suppress in a specified period supplying of generated power generated by power generator installed in a power-consuming area to a commercial electrical power system. Upon the instruction acquirer acquiring the instruction, a water heater controller commands a water heater installed in the power-consuming area to perform a water heat-up operation when a predetermined condition is satisfied in the specified period.

Control device, control method for water heater, and program

A flow damper including a cylindrical vortex chamber, a small flow-rate pipe connected to a peripheral plate of the vortex chamber along a tangential direction, a large flow-rate pipe connected to the peripheral plate with a predetermined angle with respect to the small flow-rate pipe, an outlet pipe connected to an outlet formed in a central part of the vortex chamber, and a pressure equalization pipe with respective ends being connected to the peripheral plate on opposite sides of the outlet and at positions closer to a connection portion between the small flow-rate pipe and the large flow-rate pipe than positions facing each other, putting the outlet therebetween. The pressure equalization pipe is arranged with at least a part thereof is located at a higher position than a top plate of the vortex chamber, and an outgassing hole is provided at an uppermost part of the pressure equalization pipe.

Flow damper, pressure-accumulation and water-injection apparatus, and nuclear installation

To include a cylindrical vortex chamber, a small flow-rate pipeconnected to a peripheral plateC of the vortex chamberalong a tangential direction thereof, a large flow-rate pipeconnected to the peripheral plateC with a predetermined angle with respect to the small flow-rate pipe, an outlet pipe connected to an outletformed in a central part of the vortex chamber, and a straightening platethat is arranged in a part between the outletand the peripheral plateC of the vortex chamber, and when jets flow into the vortex chamberfrom the small flow-rate pipeand the large flow-rate pipe, straightens impinging jets from the small flow-rate pipeand from the large flow-rate pipehaving flowed into the vortex chambertoward the outlet
