医院建筑的设计不同于其它公用建筑。采暖空调与通风设计针对医院而言,就是为病人及医护人员提供安全的、舒适的就医及工作环境。而目前使用的《综合医院建筑设计规范》(JGJ49—88)已难于满足现代化医院的建设及使用;特别是传染病的设计措施的条文几乎是空白。我院设计了国内多家医院,其中包括肠道传染病、肝病及呼吸道传染病SARS医院,下面就呼吸道传染病医院通风空调设计的特殊性谈谈我们的设计体会。 相似文献

Confined groundwater system in Tokyo 总被引：1，自引：0，他引：1

The Musashino Terrace and the Shitamachi Lowland, the main urban areas in the Tokyo metropolis, are in the eastern part of Tokyo and are underlain by thick Quaternary sediments. The geologic structrue of these sediments has a general strike of WNW—ESE, with a gentle dip to the east in the western part of the Musashino Terrace, and strikes generally to the E—W with a gentle dip to the north in the eastern part of the terrace and strikes WNW—ESE to N—S with a very gentle dip to the east in the Shitamachi Lowland. The basal sediments in this area consist chiefly of massive thick silty layers, whereas the sediments overlying them consist of alternating layers of silt, sand, and gravel, which act as confined aquifers throughout the Musashino Terrace and the Shitamachi Lowland. Confined groundwater systems are being developed in the Tama District, the western part of the terrace, and are mainly recharged with river water from the Tama River. The unconfined groundwater system is being developed in the surface layers such as terrace sand and gravel formations and the Kanto Loam Formation. These confined aquifers that are being developed throughout the terrace and the lowland have been exploited for household water supplies and industrial and air-conditioning use for nearly seven decades. The heavy utilization of the confined groundwater, however, has caused a major lowering of groundwater levels. As a result of the lowering of groundwater levels, land subsidence has occurred all over the Lowland and the terrace. At this time the national government and the Tokyo Metropolitan Government restricted groundwater withdrawals for industrial, air-conditioning use and the others except for household supply. Owing to these restrictions, not only have the water levels recovered, but land subsidence has rapidly declined since around 1973. 相似文献

Underground railway systems, can generate heat from their operations to raise the temperatures of carriages and the station substantially. This may lead to passenger discomfort and complain especially in warm weather conditions that prevail in Tehran if underground environment is not cooled. Transportation air conditioning Committee of American Society of Heating, Refrigerating and air-conditioning Engineers proposed the Relative Warmth Index for thermal comfort design and investigation in subway environment. In this research, thermal comfort at Tehran metro stations and carriages of lines 1 and 2 has been studied using this index. The measurements were taken during two periods of September 2006 and July 2007 at different zones of stations. For this purpose, temperature, relative humidity and air velocity were measured at different times. The status of the air-conditioning systems together with passenger traffic was also recorded. A total number of 231 measurements including 114 and 117 measurements were carried out in September 2006 and in July 2007 respectively. The measurements in September 2006 did not exceed the thermal limit. However, it did exceed in July 2007. In comparison, with thermal comfort level of metros all over the world, Tehran Metro stands in an acceptable condition, while the maximum capacity of air-conditioning systems was not used, if so the thermal comfort condition would be better. 相似文献

郑州市广泛分布着第四系松散堆积物,其特点是颗粒细,厚度大,含水介质主要为细颗粒的砂层。由于地下水富水性好,目前郑州市浅层地温能开发利用主要以地下水地源热泵工程为主。传统正循环泥浆钻探工艺施工的地温空调井,普遍存在洗井困难、涌水量和回灌量偏小的问题,在很大程度上限制了地下水地源热泵工程的推广使用。针对这一问题,本次采用泵吸反循环工艺施工地温空调井。施工过程及试验数据对比分析表明,在细颗粒松散沉积物分布区,采用泵吸反循环钻探工艺施工地温空调井,对提高施工进度、增大出水量和回灌量等方面具有显著优势,可以为类似地区地温空调井的施工提供借鉴。 相似文献
