Title: Innovations by Hidenao Kawai
Introduction
Hidenao Kawai is a notable inventor based in Noda, Japan. He has made significant contributions to the field of air-conditioning and environmental control systems. With a total of 2 patents, Kawai's work focuses on enhancing temperature control and air quality in various settings.
Latest Patents
One of Kawai's latest patents is an air-conditioning control apparatus using a heater. This invention features a heater that has increased quick responsiveness to temperature control of air. The air conditioner can achieve highly accurate temperature control by utilizing the heater. A duct unit containing heat sources, such as electric lamps, is attached to an air duct. The air that comes into contact with the glass bulbs of the electric lamps is heated by radiant heat and transferred heat generated by lighting the lamps. This design allows for improved temperature control responsiveness. The system includes a first heater and a second heater in the air duct, with temperature sensors for controlling these heaters. This setup enables two-stage temperature control with different resolutions, resulting in an air conditioner that excels in accuracy and controllability.
Another significant patent by Kawai is a rearrangeable partial environmental control device. This invention is designed for environments requiring clean air, such as manufacturing plants for integrated circuits, chemicals, foods, and hospitals. The device allows controlled air to blow out from one side and be absorbed into the other side of the room. The blowing and absorbing surfaces are divided based on a predetermined module, allowing for flexibility in the arrangement of ventilating units. This modular design enables the controlling system of temperature or air cleanliness to be rearranged as needed. The room is divided into a supply chamber, a mixing chamber, an environmental control chamber, and a return chamber, ensuring that conditioned air flows as required.
