重庆市酒店类建筑空调工程设计能效比调研

Survey of design energy efficiency ratio of air conditioning systems for hotel buildings in Chongqing

调研了重庆市12个酒店建筑的空调工程设计,从冷热源系统、水系统、风系统和整个空调工程等方面分析了空调设计能效比。结果表明,冷热源系统设计能效比对整个空调工程设计能效比的影响最大,设计中要避免冷热源系统装机容量超出设计负荷过多和空调冷热水泵兼用而不作调节,尽量减少采用定风量全空气系统等,可有效提高空调工程设计能效比。调研结果反映出重庆市酒店类建筑空调工程节能设计水平参差不齐,如以各设计能效比的平均值作为设计最低标准,将使公共建筑空调工程的节能设计水平得到提升。

Surveys the air conditioning design of 12 hotel buildings in Chongqing, analyses the design energy efficiency ratio from the aspects including cold and heat sources, water circulation system, air system and whole air conditioning engineering. The results show that the cold and heat sources have prominent impacts on the air conditioning design energy efficiency ratio （EERACD）, and it should be avoided in design process to make the cold and heat sources oversized, use the same pump as chilled water and hot water supply equipment without adjustment, and overuse of all-air systems, thus to improve EERACD. The surveying results show that the energy efficiency design status of hotel buildings in Chongqing is diverse from each other. Compares and analyses the difference of EERACD in these hotels, and proposes a mean value of the EERACD as the minimum energy efficiency design standard, aiming to promote enhancement of energy efficiency in public buildings.
