【発明の詳細な説明】
［産業上の利用分野］
本発明は新規な熱移送媒体組成物に関し、詳しくは特に
熱媒の循環を利用した各種の冷暖房システムに用いるの
に適した新規な熱移送媒体組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a novel heat transfer medium composition, and more particularly to a novel heat transfer medium composition suitable for use in various heating and cooling systems that utilize circulation of a heat medium. Relating to media compositions.
［従来技術および発明が解決しようとする問題点］現在
、温水や冷水を熱媒として、熱源から熱利用場所へ熱媒
を循環して冷・暖房を行うシステムは、例えば吸収式冷
温水器による空調システムや床暖房システムなどに見ら
れるように、世間一般に幅広く用いられている。[Prior art and problems to be solved by the invention] Currently, there are systems that perform cooling and heating by circulating hot water or cold water as a heat medium from a heat source to a place where heat is used. It is widely used throughout the world, as seen in air conditioning systems and floor heating systems.
従来よりその熱移送媒体としては、水単独かまたは水に
凍結防止剤としてグリコール化合物を配合したものがよ
く使用されている。しかしながら、このような従来より
ある熱移送媒体は、動力ポンプなどによる移送に多大な
エネルギーを要するとともに、長期間使用した場合、水
中に含まれる機器の不純物の沈積などにより配管や放熱
器に多量のスケールが付着するという問題点があった。Conventionally, as the heat transfer medium, water alone or water mixed with a glycol compound as an antifreeze agent has often been used. However, such conventional heat transfer media require a large amount of energy to be transferred using power pumps, etc., and when used for a long period of time, a large amount of heat transfer medium is deposited on piping and radiators due to the accumulation of impurities from equipment contained in the water. There was a problem with scale adhesion.

。Such scale adhesion significantly reduces the heat transfer efficiency of the heat medium, causing the thermal energy obtained from the heat source to not be efficiently utilized at the heat utilization site. Furthermore, the corrosive nature of water causes rust on pipes and radiators, which may reduce not only the durability of the system but also the energy efficiency, as in the case of scale adhesion.
