沈阳某办公楼水源热泵系统耗电量实测与分析

Measurement and Analysis on Electricity Consumption of Water Source Heat Pump System for Office Building in Shenyang

通过整理和分析沈阳市某办公建筑水源热泵系统耗电量及气象因素数据资料,研究水源热泵系统耗电量变化特征及其随气象因素的变化规律。主要采用相关性分析法,定量分析了水源热泵系统耗电量与各气象因素之间的相关性系数。结果表明水源热泵系统耗电量主要在采暖季,水源热泵系统耗电量与室外干球温度、降水量、相对湿度及日照时数均呈现负相关性。室外干球温度和降水量对办公建筑水源热泵系统耗电量影响显著,而相对湿度、日照时数对办公建筑水源热泵系统耗电量影响不显著。

To study the characteristics of electricity consumption and the relationship between electricity consumption of water source heat pump system and meteorological factors,data for meteorological factors and electricity consumption of water source heat pump system have been collated and analyzed. Correlation analysis was used to calculate the correlation coefficient between electricity consumption and meteorological factors qualitatively. The results showed that annual electricity consumption was mainly used for heating,and outside dry-bulb temperature,precipitation,relative humidity and hours of sunshine were negatively correlated with electricity consumption. Electricity consumption of heat pump system was significantly influenced by outside dry-bulb temperature and precipitation,while influence of humidity and hours of sunshine were not significant.
