Title: Masahiro Nakayama: Innovator in Air Conditioning Technology
Introduction
Masahiro Nakayama is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of air conditioning technology, holding a total of 2 patents. His innovative designs focus on improving the efficiency and functionality of air conditioning systems.
Latest Patents
One of Nakayama's latest patents is for an indoor unit of an air conditioner. This invention features an air inlet located at the upper portion of the unit. The heat exchanger includes multiple plate fins arranged in parallel, allowing air to flow between them. Additionally, heat transfer tubes are perpendicularly inserted into the plate fins and arranged to optimize the air flow direction. The design includes a lower front heat exchanger, an upper front heat exchanger, and a rear heat exchanger, all strategically arranged to surround the circulating fan. Notably, the air pressure loss of the lower front heat exchanger is minimized compared to the other heat exchangers.
Another significant patent is related to a refrigeration cycle that utilizes a cooling medium circuit. This system connects a compressor, a heat-source-side heat exchanger, a decompressor, and a user-side heat exchanger in succession. The invention addresses the challenge of refrigerating machine oil that has low solubility with the cooling medium. Nakayama's design adjusts the internal diameter of a down comer to ensure that the flow velocity of the cooling medium is sufficient to prevent the refrigerating machine oil from floating.
