摘  要:本设计为南京某医院地源热泵工程设计,通过方案比较,在负荷计算的基础上,采用了风机盘管加新风系统形式。风机盘管为卧式暗装,新风不承担室内负荷,室内回风与新风分别经散流器送出。新风从室外引入,由各层新风机组处理供应各层。冷冻水由地下室的冷冻机房供应,采用了闭式异程两管制水系统。水管用泡沫橡塑保温,风管采用离心玻璃棉。设计工程中考虑了消声、减振和防火排烟的措施。近年来,随着我国社会经济的发展及人民生活水平的不断提高,改善建筑热舒适条件已成为一个比较突出的要求。空调作为目前改善建筑热舒适条件的工具,早已悄悄进入我们的生活。据有关方面调查,在上海空调家庭拥有率已达到平均1台以上。然而,随着空调设备的日益普及,建筑耗能量势必将迅猛增加,对大气环境的污染也将日趋严重。如何在建筑热舒适条件得到改善的条件下把建筑耗能量减下来,减轻对大气环境的污染,成了暖通界人士首要其冲需要解决的问题。现阶段,在保证使用功能不降低的情况下,我们应采取各种有效的技术和管理措施,把新建房屋建筑的能耗较大幅度地降下来,对原有建筑物有计划地进行节能改造,达到节省能源、保护环境和提高人民生活质量的目的[1]。地源热泵作为一种有益环境、节约能源和经济可行的建筑物供暖及制冷新技术越来越受到关注。它是利用地下相对稳定的土壤温度,通过媒介质来获取土壤内冷(热)能量的新型装置,可一年四季方便地调节建筑内的温度。由于该制冷供热方式不存在能量形式的转换,几乎是一种能量的“搬运”过程,因而其能量转换效率高、运营成本低。

ABSTRACT:The design for the ground source heat pump in a hospital in Nanjing, engineering design, through the program comparison, based on the load calculation, using a fan coil plus fresh air system in the form. Horizontal concealed fan coil is the new indoor air not bear the load, indoor return air and fresh air are sent out by the diffuser. The introduction of fresh air from outside by layers of fresh air handling unit supply layers. Chilled water supply from the basement of the refrigerated room, the use of two different process control in closed water systems. Water pipes with foam rubber insulation, duct using centrifugal glass wool. Considered in the muffler design engineering, vibration and fire smoke measures. In recent years, as China's social and economic development and continuous improvement of living standards, improve thermal comfort conditions of buildings has become a more prominent requirements. Air-conditioning as the current conditions to improve building thermal comfort tools already crept into our lives. According to relevant survey, households have air conditioning in Shanghai has reached an average of more than 1 set. However, with the increasing popularity of air-conditioning, building energy consumption is bound to the rapid increase in atmospheric pollution will also be more serious. How to improve building thermal comfort conditions of construction under the conditions cut down energy consumption, reduce environmental pollution in the atmosphere, became the first HVAC professionals need to address the problem of its punch. At this stage, ensure that the use function is not reduced in the case, we should take all effective technical and management measures, the energy consumption of new housing construction down more significantly, the original buildings are planned for energy saving , to save energy, protect the environment and the purpose of improving the quality of life [1]. Ground source heat pump as an environmentally friendly, economically viable energy conservation and building heating and cooling technology more and more attention. It is the use of underground soil temperature is relatively stable through the mass media to get the soil cold (heat) energy of the new device can be easily adjusted throughout the year the temperature within the building. Heating due to the cooling mode does not exist in the form of energy conversion, energy, almost a "move" process, and thus the energy conversion efficiency, low operating costs

Key words: air conditioning; fan coil system and the new wind, new wind
