– Study on improvement effects with a renewal of DHC system using river water heat –

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.
