Title: Akira Hatakeyama: Innovator in Refrigeration and Air Conditioning Technologies
Introduction
Akira Hatakeyama is a notable inventor based in Tochigi, Japan. She has made significant contributions to the fields of refrigeration and air conditioning, holding a total of 4 patents. Her innovative designs focus on improving efficiency and functionality in thermal systems.
Latest Patents
One of her latest patents is for an absorption refrigerating machine. This invention addresses the challenges faced when the efficiency of a low-temperature heat exchanger is increased, particularly when the temperature of the cooling water supplied to the absorber drops suddenly. The design ensures that the temperature of the concentrated absorbent solution does not increase abnormally, preventing crystallization. Additionally, a heat recovery device is integrated into the system to enhance performance by connecting various components effectively.
Another significant patent is for an air conditioning system that features a heat source side machine and multiple user side machines. This system utilizes a phase-changeable fluid that circulates based on the specific gravity difference between its liquid and gas phases. This innovative approach allows for efficient cooling and heating operations, while also incorporating mechanisms to quickly exhaust any bubbles or condensed liquid generated within the closed circuit.
