本文提出了一种基于雨水回收利用的农村住宅节能系统,可实现对夏季丰沛雨水的收集并将其应用于对空调室外机与住宅屋面的喷淋,以降低住宅能耗。选取南京市一典型农村住宅为研究对象,对其节能效益开展评估研究,结果表明:对于常规农村住宅,在夏季典型设计日(干球温度30℃,相对湿度65%)时,经雨水喷淋后空调室外机的冷凝温度可降低9.5℃,机组COP提高24.7%,该系统在整个制冷期可节省空调耗电量17.8%。将收集到的雨水用于屋面喷淋降温,整个制冷季可节省空调耗电量3.6%。研究结果可为夏热冬冷地区农村住宅的节能设计提供参考。 相似文献

我国城镇住宅夏季空调能耗状况分析 总被引:6,自引:3,他引:3
根据调查和计算,利用模拟归纳法对我国城镇住宅夏季空调能耗状况进行了定量分析.结果表明,目前我国城镇住宅夏季空调的总体能耗水平较低,但增速较快,且不同气候区之间差异较大.2005年全国城镇住宅夏季空调总耗电量约为285亿kwh,平均耗电指标约为2.65 kWh/m2.我国城镇住宅空调能耗前4位的地区是:广东、浙江、江苏和湖北,它们的空调总能耗约占全国城镇住宅空调总能耗的51.8%,广东、福建、重庆、浙江、上海、湖北、江苏和广西的空调能耗指标较高,它们是我国城镇住宅空调节能的重点地区. 相似文献

Few studies exist in China examining the association of ambient air pollution with morbidity outcomes. We conducted a time-series analysis to examine the association of outdoor air pollutants (PM10, SO2, and NO2) with hospital outpatient and emergency room visits in Shanghai, China, using 3 years of daily data (2005-2007). Hospital and air pollution data were collected from the Shanghai Health Insurance Bureau and Shanghai Environmental Monitoring Center. Using a natural spline model, we examined effect of air pollutants with different lag structures including both single-day lag and multi-day lag. We examined effects of air pollution for the warm season (from April to September) and cool season (from October to March) separately. We found outdoor air pollution (SO2 and NO2) was associated with increased risk of hospital outpatient and emergency room visits in Shanghai. The effect estimates varied for different lag structures of pollutants’ concentrations. For lag 3, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 corresponded to 0.11% (95%CI: −0.03%, 0.26%), 0.34% (95%CI: 0.06%, 0.61%) and 0.55% (95%CI: 0.14%, 0.97%) increase of outpatient visit; and 0.01% (95%CI: −0.09%, 0.10%), 0.17% (95%CI: 0.00%, 0.35%) and 0.08% (95%CI: −0.18%, 0.33%) increase of emergency room visit. The associations appeared to be more evident in the cool season than in the warm season. In conclusion, short-term exposure to outdoor air pollution was associated with increased risk of hospital outpatient and emergency room visits in Shanghai. Our analyses provide evidence that the current air pollution level has an adverse health effect and strengthen the rationale for further limiting air pollution levels in the city. 相似文献

Energy and related health issues are of growing concern worldwide today. To investigate the potential public health and economic impact of ambient air pollution under various low-carbon energy scenarios in Shanghai, we estimated the exposure level of Shanghai residents to air pollution under various planned scenarios, and assessed the public health impact using concentration-response functions derived from available epidemiologic studies. We then estimated the corresponding economic values of the health effects based on unit values for each health outcome. Our results show that ambient air pollution in relation to low-carbon energy scenarios could have a significant impact on the future health status of Shanghai residents, both in physical and monetary terms. Compared with the base case scenario, implementation of various low-carbon energy scenarios could prevent 2804-8249 and 9870-23,100 PM10-related avoidable deaths (mid-value) in 2010 and 2020, respectively. It could also decrease incidence of several relevant diseases. The corresponding economic benefits could reach 507.31-1492.33 and 2642.45-6192.11 million U.S. dollars (mid-value) in 2010 and 2020, respectively. These findings illustrate that a low-carbon energy policy will not only decrease the emission of greenhouse gases, but also play an active role in the reduction of air pollutant emissions, improvement of air quality, and promotion of public health. Our estimates can provide useful information to local decision-makers for further cost-benefit analysis. 相似文献

Ambient carbon monoxide (CO) is an air pollutant primarily generated by traffic. CO has been associated with increased mortality and morbidity in developed countries, but few studies have been conducted in Asian developing countries. In the China Air Pollution and Health Effects Study (CAPES), the short-term associations between ambient CO and daily mortality were examined in three Chinese cities: Shanghai, Anshan and Taiyuan. Poisson regression models incorporating natural spline smoothing functions were used to adjust for long-term and seasonal trend of mortality, as well as other time-varying covariates. Effect estimates were obtained for each city and then for the cities combined. In both individual-city and combined analysis, significant associations of CO with both total non-accidental and cardiovascular mortality were observed. In the combined analysis, a 1 mg/m3 increase of 2-day moving average concentrations of CO corresponded to 2.89% (95%CI: 1.68, 4.11) and 4.17% (95%CI: 2.66, 5.68) increase of total and cardiovascular mortality, respectively. CO was not significantly associated with respiratory mortality. Sensitivity analyses showed that our findings were generally insensitive to alternative model specifications. In conclusion, ambient CO was associated with increased risk of daily mortality in these three cities. Our findings suggest that the role of exposure to CO and other traffic-related air pollutants should be further investigated in China. 相似文献

Coarse particles and mortality in three Chinese cities: the China Air Pollution and Health Effects Study (CAPES) 总被引:1,自引:0,他引:1

Evidence concerning the health risks of coarse particles (PM10-2.5) is limited. There have been no multi-city epidemiologic studies of PM10-2.5 in developing Asian countries. We examine the short-term association between PM10-2.5 and daily mortality in three Chinese cities: Beijing, Shanghai, and Shenyang. PM10-2.5 concentrations were estimated by subtracting PM2.5 from PM10 measurements. Data were analyzed using the over-dispersed generalized linear Poisson models. The average daily concentrations of PM10-2.5 were 101 μg/m3 for Beijing (2007-2008), 50 μg/m3 for Shanghai (2004-2008), and 49 μg/m3 for Shenyang (2006-2008). In the single-pollutant models, the three-city combined analysis showed significant associations between PM10-2.5 and daily mortality from both total non-accidental causes and from cardiopulmonary diseases. A 10-μg/m3 increase in 1-day lagged PM10-2.5 was associated with a 0.25% (95% CI: 0.08 to 0.42) increase in total mortality, 0.25% (95% CI: 0.10 to 0.40) increase in cardiovascular mortality, and 0.48% (95% CI: 0.20 to 0.76) increase in respiratory mortality. However, these associations became statistically insignificant after adjustment for PM2.5. PM2.5 was significantly associated with mortality both before and after adjustment for PM10-2.5. In conclusion, there were no statistically significant associations between PM10-2.5 and daily mortality after adjustment for PM2.5 in the three Chinese cities. 相似文献
