Latest Patents
Yoshimi's latest patents include a hot-water supply system that features a control unit designed to estimate boiling time based on the amount of hot water stored in a tank at 23:00. The system adjusts the boiling start time to ensure that the boiling operation is completed just before 7:00. For instance, if the hot water amount is smaller at 23:00, the boiling time is extended, and the start time is moved earlier. Conversely, if the hot water amount is larger, the boiling time is shortened, and the start time is delayed. Another significant patent is for a hot-water supply system with a heat pump cycle. In this system, the control unit manages the operation of an expansion valve based on the temperature difference between the refrigerant and water temperatures in the heat exchanger. The control unit sets an upper limit for the valve opening to achieve the desired hot-water temperature while maintaining efficiency.
