夏热冬冷地区空调水系统输送能效比的探讨

On EC(H)R of Air Conditioning Water System in Hot Summer& Cold Winter Region

民用建筑空调水系统中,水泵的能耗是不可忽视的一部分。空调水系统输送能效比是水系统性能节能评价的主要指标之一。《公共建筑节能设计标准》(GB50189-2005),(DB33/1036-2007)及《民用建筑供暖通风与空气调节设计规范》(GB50736-2012)均规定了最大输送能效比的限值。以工程实例为基础,输送能效比的几种计算方法各有其限值的适用性。

In the air conditioning water system for civil construction, energy consumption of water pump can＇t be neglected. EC （H）R of air conditioning water system is a major indicator to evaluate the energy efficiency of water system. Design Standard for Energy Efficiency of Public Buildings （GB50189-2005）, （DB33/1036-2007） and Design Code for Heating Ventilation and Air Conditioning of Civil Buildings （GB50736-2012） all set maximum limits for EC （H）R. By combing engineering practical examples, this paper introduces calculation method for EC （H）R and analyzes usability of several limit values.
