Title: Seiji Ookoshi: Innovator in Heat Pump Technology

Introduction

Seiji Ookoshi is a notable inventor based in Fuji, Japan. He has made significant contributions to the field of heat pump technology, holding 2 patents that showcase his innovative approach to energy efficiency and water heating solutions.

Latest Patents

One of his latest patents is a heat-pump-type water heater. This invention features a heat source unit that includes a compressor, a heat-source-side heat exchanger, an outdoor blower, and a controller for electric devices. The hydrothermal exchange unit accommodates water heat exchangers, water pipes, pumps, and a controller, connecting to the heat source unit via refrigerating pipes and electric wiring. The tank unit stores hot water obtained from heat exchange, while the housing design prevents freezing of the water pipes, enhances compactness, and improves operational efficiency.

Another significant patent is the hot-water supply apparatus. This invention allows for defrosting operations by directing refrigerant discharged from a compressor to an outdoor heat exchanger. The refrigerant is then returned to the compressor through a water-heat exchanger while operating a pump. Quick defrosting is also possible by bypassing the pump. The system detects the temperature of water flowing into the water-heat exchanger, enabling selective execution of defrosting operations based on the detected temperature.
