上海某学生公寓CO_(2)热泵-太阳能互补热水系统运行效果评估

Evaluation of CO_(2) Heat Pump-Solar Multi-Energy Complementary Hot Water System for Student Housing in Shanghai

我国CO_(2)排放力争于2030年前达到峰值,努力争取2060年前实现碳中和,建筑电气化和可再生能源利用是建筑碳中和的主要路径。以上海某学生公寓为案例,分析CO_(2)热泵-太阳能互补热水系统实际运行效果。结果显示,本热水系统与电热热水器系统相比,年节电量为75.2万kWh,节电率为90.1%,节碳量为592.6 tCO_(2)。与燃气热水器系统进行比较时,年节电量为56.5万kWh,节电率为87.3%,节碳量为445.2 tCO_(2)。CO_(2)热泵-太阳能互补热水系统节能效果可观,可在有热水需求的项目中推广应用,有助于碳达峰和碳中和目标实现。

China's carbon dioxide emissions strive to reach the peak by 2030,and strive to achieve carbon neutralization by 2060.Building electrification and renewable energy utilization are the main paths of building carbon neutralization.Taking a student apartment in Shanghai as an example,this paper analyzes the actual operation effect of CO_(2) heat pump solar complementary hot water system.The results show that compared with the electric water heater system,the annual power saving of the system is 752000 kWh,the energy saving rate is 90.1%,and the carbon saving is 592.6 tCO_(2);Compared with the gas water heater system,the system can save 565000 kWh of electricity,87.3%of energy and 445.2 tCO_(2) of carbon.CO_(2) heat pump-solar complementary hot water system has considerable energy saving effect,which can be popularized and applied in projects with hot water demand,and is helpful to achieve the goal of"carbon peak and carbon neutralization".
