摘要

本文针对地下工程的特点,提出一种适用于其空调系统能效评价的指标——运行需求能效比,并给出明确定义和计算方法。建立了空调系统从整体到局部的能效评价方法,给出各子系统的能效参考限值。选取夏热冬冷地区某小型地下工程为实例,进行空调系统的能效评价,结果表明:该系统在日常维护期处于较低的能效水平,根据评价结果对原工程进行改造,改造后系统总能效提高了18.9%,验证了该评价方法的可行性和合理性。
        According to the features of protective engineering, an index for energy efficiency evaluation of an air-conditioning system is proposed, which is named as operating-demand energy efficiency ratio. Its definition and calculation method are provided in this paper. The energy efficiency evaluation strategy of an air-conditioning system is established from the whole system and its components, and the limiting values of the energy efficiency are provided. By taking a small underground engineering in hot summer and cold winter zones as an example, the energy efficiency evaluation of the air-conditioning system was carried out. The evaluation result shows that the system exhibited a daily low level of energy efficiency. On the basis of the results, the original project was retrofitted, and the energy efficiency of the system was improved by 18.9%, which verifies the feasibility and rationale of the proposed evaluation method.
