家用新风机净化能效评价指标
Cleaning energy efficiency evaluation index of household outdoor air ventilators
摘要：
在综合分析新风机结构功能及运行特征基础上，提出了一种表示家用新风机净化能效的评价指标。该指标通过净化收益和能源代价的相对大小来评判新风机的性能优劣。净化收益主要考虑了新风侧和回风侧两部分洁净空气量，代价部分考虑了设备本身所消耗的电功率及引入室外新风造成的潜在能耗。采用该评价指标对北京和广州两地冬季某特定工况下不同类型新风机的净化能效情况进行了对比分析。
Abstract：
Based on the comprehensive analysis of the structure and operation performance of household outdoor air ventilators, develops an approach to evaluate their cleaning energy efficiencies through a relationship between the cleaning benefit and energy cost. The cleaning benefit includes the clean air delivery rate (CADR) contributed by outdoor air and return air, respectively. The cost includes two parts: the electrical power consumed by the equipment and the potential energy consumption caused by the introduction of outdoor air. Analyses the cleaning energy efficiency of different types of outdoor air ventilators under typical working conditions in Beijing and Guangzhou using the evaluation index.
