Title: Tetsunobu Okamura: Innovator in Heat Pump Technology
Introduction
Tetsunobu Okamura is a notable inventor based in Ohira, Japan. He has made significant contributions to the field of heat pump technology, holding a total of 4 patents. His innovative designs focus on improving hot-water supply systems, making them more efficient and practical for everyday use.
Latest Patents
One of Okamura's latest patents is a heat pump hot-water supply system. This system heats water through heat exchange between high-temperature refrigerant of a heat pump circuit and water of a water circulating circuit. It functions as an instantaneous water heater unit, which heats water supplied through a water supply pipe and delivers hot water to a using end unit. This design eliminates the need for a large-capacity hot-water storage tank.
The system addresses the challenge of insufficient heat of condensation to heat water, which occurs when pressure conditions of the heat pump circuit are not stabilized immediately after the start of operation. To mitigate this, during the short period of rising time, hot water stored in a hot-water supply tank is mixed with water from the water heat exchanger. This mixture is then supplied to maintain the hot water at a preset temperature, allowing for the use of a smaller hot-water supply tank.
