Description

多联机空调系统的电量分摊方法 技术领域
本发明涉及空调电量计算领域,具体提供一种多联机空调系统的电量分摊方法。
背景技术
随着多联机空调系统的日益普及,其电量计算方式也成为人们备受关注的问题。目前的计费方式有以下几种:按面积分摊,按使用时间分摊,按制冷剂流量分摊,按室内机电量分摊,按制冷剂侧冷量分摊以及按风侧冷量分摊等。具体地,现有电量计算方式中最为准确的方式为按照制冷剂的流量分摊电量,该方案的优选在于考虑了各个末端对制冷剂的实际需求量,以使电子膨胀阀的开度可以得到精确检测,但是,其缺点在于流量与制冷量未必成正比,间接测流量精度受限,数据处理难度较大。而按照室内机电量分摊电量的方式的优选在于测量精度高,计算简单,数据直观,可更好地指导用户节能;但是,其缺点在于硬件初期投资较高,安装难度大,单独配电需提前设计,并且电量也不能完全代表耗冷量。由此可见,现有电量计算方式往往对单个因素过度偏重,从而忽略了其他因素对电量起到的重要作用,对精度高的计费方法硬件配置过于复杂,在实际情况中施工难度过大,工程量过高。
