Abstract
In this research, we will adapt to the three main air conditioning methods (DHC system, central heat source air-conditioning system, package air conditioning system) and supply renewable energy such as river water to improve efficiency of heat pump "the heat source water network system" was studied. Specifically, a model study based on energy simulation was conducted on established urban area where businesses, hotels, hospitals and other buildings are mixed, and medium- and large-scale buildings are mixed. As a result, it was found that the energy saving effect by introduction of the heat source water network sysytem to the model district, the effect by winter heating and hot water supply is particularly large, and energy consumption amount of about 8.0% can be reduced.
