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。地源热泵系统已经逐渐成熟，所以在热源设计中选择了环保、节能、运行稳定的地源热泵系统，虽然初投资成本会稍高，但由于日后系统的稳定性高，不需要专业人员维护，会逐渐收回成本。

ABSTRACT:This design for nanjing some hospital ground source heat pump engineering design, through the scheme comparison in load calculation, and on the basis of using the primary air fan coil system form. Fan coil is horizontal dark outfit, fresh air does not undertake indoor load, indoor air return respectively with new sent out by the scattered flow device. Fresh air from outdoor introduced by each layer, fresh air units. Each layer handle supply By freezing water supply cooling room in the basement, using a different process two control closed water system. Conduit in foam rubber insulation, duct using centrifugal glass cotton. Design engineering in considering the sound attenuation, damping and fire smoke exhaust measures. The ground source heat pump system has been gradually mature, so in heat source design chose environmental protection, energy saving, run stable ground source heat pump system, although the initial investment cost will be slightly tall, but due to the high stability, future system does not need professional maintenance, will gradually withdraw cost.
Key words: air conditioning; fan coil system and the fresh air, fresh air ，ground source heat pump
