■Summary
Contributing to the safety and energy saving of hot bath facilities. We will achieve significant reductions in running costs for water, heat, and electricity.
■Rotation speed control of filtration circulation pump (chlorine concentration control method)
Flow of Shoei's SBES filtration circulation pump rotation speed control (chlorine concentration control method) This system uses the change in chlorine concentration measured by an automatic residual chlorine concentration control device (polarographic method) to determine the bathtub usage load and contamination status, and then This is a mechanism that controls the rotation speed and reduces power consumption. Highly efficient power consumption control is possible by changing from 24-hour continuous commercial operation to minimum filtration capacity operation mode.
■Rotation speed control of filtration circulation pump (bather sensing control method)
Flow of Shoei's SBES filtration circulation pump rotation speed control (bather detection control method) This system installs a radio wave bather sensor in the bathroom, identifies the water quality load from the frequency of bathing, and then switches on the inverter. It is a mechanism that can be operated to control the rotation speed and reduce power consumption. Even if it is difficult to control the chlorine concentration due to the quality of the hot spring water, this system can save energy for the filtration circulation pump.
■Jacuzzi blower/jet pump operation control based on bather detection
Shoei's SBES flow of operation control for Jacuzzi blowers and jet pumps based on bather detection This system detects the presence or absence of a user using a radio wave sensor installed in the bath, and then shuts down the bath to reduce power consumption.
From continuous operation during business hours to the minimum required operation method, it is possible to reduce wasteful power consumption.
■Filter backwash water reuse system
Flow of Shoei's SBES filter backwash water reuse system This system instantly filters backwash wastewater from the filter through a special filter and reuses it for backwashing, reducing water and energy consumption. Compared to the backwashing method that normally drains water, it is possible to reduce wastewater by more than 80%, and when backwashing, the amount of chlorine injected can be increased to disinfect the inside of the filter, hair catcher, and filter at the same time. is.
