摘 要:毛细管网辐射供冷暖是一种在建筑物内部顶、墙面、地面等铺设毛细管散布冷热量的系统。它能像人体皮肤中的毛细管一样，均匀地向室内辐射冷热量，相对于传统的制冷热方式具有冷热感舒适、冷热量均衡稳定、节能、免维修等特点，是一种极为理想的供冷暖方式。广泛应用于别墅、住宅、宾馆大堂、游泳池馆等场所，尤其别墅和住宅使用更为普遍。本设计是针对南京市一幢五层别墅进行的毛细管网辐射供冷暖系统设计。系统设计面积约200㎡，采用毛细管辐射供冷暖及独立新风设计，冷负荷与湿负荷分开处理。冷热源选用空气源热泵机组。房间毛细管网以屋顶和墙面铺设为主，同时满足制冷和采暖需要，采用置换新风方式把处理后的空气通过地板风道送到各个房间，统一排风或在卫生间或厨房排风，保证室内的相对湿度和空气品质，同时解决部分显热。

Abstract:Capillary radiant heating-cooling is a system using capillary tube which paved in ceiling, wall, ground radianting heat and cool. It likes the skin of people’s body, radiating heat and cool evenly to the indoor, Compared to the triditional heating-cooling methods , it is an ideal way of heating-cooling in thermal comfort, heat-cool balance and stability, energy saving, maintenance-free characteristics. It id widely used in villas, residential, hotel lobby, pool hall and other places, especially villas and residential use. This design is the capillary radiant heating-cooling system design for a five-layer villa in Nanjing. Design-area is about ​​200 square meters and using capillary radiant heating-cooling and dedicated outdoor air system, separating cooling load and wet load. Choosing the air-source heat pump as the cooling and heat resource. The capillary network is mainly extended in roof and walls of the room, satisfying the laid of cooling and heating at the same time .The air after treatment the replacement is sent to each room through tubes in the floor. Setting unified air exhaust or exhausting in the toilet or kitchen , ensuring relative humidity indoor and air quality and simultaneously solving part of sensible heat.
