VRV集中空调与区域供冷单位冷量能耗的比较研究

Comparison research of unit cooling energy consumption of VRV air-conditioning and district cooling

针对VRV技术和区域供冷技术进行单位冷量能耗的比较研究。结果表明:1)区域供冷的单位冷量能耗近似正比于管道当量长度;而VRV空调单位冷量能耗可近似认为在某管道长度区间内变化不大,并可主要分为3个范围,不同范围内单位冷量能耗值不同。2)一个系统采用VRV技术节能还是采用区域供冷技术节能,取决于区域制冷站与用户的距离以及VRV系统供冷的管道当量长度。

Makes comparison research of the unit cooling energy consumption between the variable refrigeration volume（VRV） and district cooling. As a result, the unit cooling energy consumption of district cooling is increased with the equivalent length of pipelines, while the unit cooling of energy consumption is constant in a certain length from the main machine to user of VRV system. The comparison of the unit cooling energy consumption shows that it should have different choice under different conditions.
