空調用屋外機の排熱特性及びエネルギー効率に関する研究 : 第1報-実測による屋外環境の影響評価  [in Japanese] The Characteristics of Waste Heat and Energy Efficient of Air Conditioning Outdoor units : Part 1 The Influence Evaluation about Outdoor Environment by Measurement  [in Japanese]

空調排熱の影響による気温高温化の原因を把握するために、空冷式屋外機及び水冷式屋外機の排熱特性の違いを明らかにし、気温上昇に寄与する顕熱排熱の特性について検討を行った。また、顕熱排熱を主体とする空冷式屋外機の稼働状況が空調機のCOPに及ぼす影響について検討した。本報告では、夏季及び冬季において、単一の屋外機に関する現場実測を行うことにより、空調用屋外機の屋外環境評価及びエネルギー効率について検討を行った。

By the frequency of extensive damages from the hurricanes by concentrated torrential rainfall and the rise of the water temperature of sea level, global environment issues and global warming are more and more serious in recent years. In these as a background, researches aiming at solving the influence which the artificial waste heat, especially, waste heat from air conditioning devices has on urban environment and urban canyon are made strenuously. On the other hand, authors are observing the temperature and humidity distribution in Kumamoto city until now and considered the temperature rise by artificial waste heat and the change of land cover condition. In order to grasp influence air conditioning waste heat which is a kind of artificial waste heat has on urban canyon, the difference in the characteristics of the waste heat of dry cooling outdoor unit and cooling tower was clarified, the characteristic of sensible waste heat which contributes to temperature rise was examined. Moreover, the influence that operation condition of dry cooling outdoor unit which is generated sensible waste heat mainly gave to COP of air conditioning device was examined. The environmental evaluation and energy efficient of air conditioning outdoor unit were examined by performing measurement aimed at single outdoor unit.
