Abstract

In 1989, district heating and cooling system using river water heat was introduced for the first time in Japan, at Hakozaki. And this system was improved with a renewal in 2012-2014. It was improved the washing method of the heat pump tube and the control method of river water intake. This paper presents a study on improvement effects with a renewal of DHC system using river water heat.
