Hybrid heat pump system using dual heat sources of ground and ambient air application to snow-melting

摘要

Recently, thermal use of the ground heat source becomes to be noticeable from view points of Global environment and Saving energy. We have had a conclusion that the heat pump system using dual heat sources of the ground and the ambient air is the desirable system which brings more decrease of the cost to construct the ground heat exchanger. Accordingly, we have developed Hybrid heat pump using these dual heat sources, which is the core apparatus for this system. This paper deals with the development and the application of the original hybrid heat pump system for Snow-melting.
