Energy Utilization Research Section
In order to address recent global warming issues, it is formulated as a national policy to promote heat pump equipment, which effectively conserves energy and reduces the amount of CO2. However, in the cold region of Hokkaido, air source heat pump equipment, which is easy to introduce to ordinary households, such as EcoCute (natural refrigerant heat pump water heater) is much less widespread than in Honshu (warm regions). One of the reasons why the equipment has not come into wide use is because of some challenges of the installation techniques (countermeasures against snow, wind and coldness) which are unique to cold regions. Therefore, we have conducted research activities for specifying the problems we face on site and suggesting early solutions.
Through these activities, we will continue to support the techniques in order to promote heat pumps in Hokkaido while listening to our customers so that our customers can safely use and be satisfied with various heat pump equipment.
