Introduction
Etsuhisa Yamada is a renowned inventor based in Kariya, Japan, known for his significant contributions to air conditioning technology. With an impressive portfolio of 49 patents, Yamada's work has been pivotal in improving the efficiency and functionality of refrigerant systems.
Latest Patents
Among his latest innovations, Yamada has developed a sophisticated ejector mechanism. This ejector features a shaft linked to a passage formation member, which defines a refrigerant passage within a body. The shaft is designed to slide within a support member that is fixed to the body, allowing for axial movement that alters the passage's sectional area. The ejector also incorporates a vibration suppressive member with two mobile ends, enhancing the system by applying loads to either enlarge or narrow the refrigerant passage dynamically.
In addition to the ejector, Yamada has also designed an advanced air conditioning system. This air conditioner comprises key components such as an inside condenser, an outside heat exchanger, and an inside evaporator. One notable feature of this system is a refrigerant circuit switcher that adapts the flow of refrigerant based on operational modes—either during heating or defrosting—ensuring optimal performance under varying conditions. The air passage switcher further enhances functionality by directing airflow through the appropriate pathways for each mode.
