通过对某公司在全国13个城市建立的购物中心空调项目的运行数据进行实测,对比了各项目的单位空调面积安装冷负荷指标和实际运行冷负荷指标。分析研究表明,出现指标显著差异的原因是空调基本设计参数的确定有误。根据项目的商业特点,确定了合理统一的空调基本设计参数,对已建商场降低空调运营成本、新建商场降低空调工程投资提供了指导。
By measuring the operating data of a company’s air-conditioning project in 13 shopping centers in China, the cold load index and the actual operating cooling load index of air-conditioning area in each project are compared. Analytical research shows that the reason for the significant difference in the indicators is that the basic design parameters of air conditioners are not correctly determined. According to the commercial characteristics of the project, a reasonable and uniform basic design parameters of air conditioners were determined, and the operation cost of the air-conditioners in the existing shopping malls was reduced, and the investment in newly-built shopping malls to reduce the air-conditioning project was provided.
