基于金属毛细管网的新型温湿度独立控制辐射空调系统设计

Design of a new temperature and humidity independent control radiation air conditioning system based on metal capillary tube

传统空调系统存在如吹风感、冷表面滋生霉菌、能效比较低等一系列弊端。为了解决这些问题,提出一种基于金属毛细管网的辐射式热泵系统,利用敷设于建筑物围护结构内的金属毛细管作为室内侧换热器,由热泵系统控制室内温度。然而,热泵系统无法保证新风供应、存在室内结露等问题,因此提出在该系统基础上复合运行太阳能溶液除湿新风系统,利用太阳能集热板收集的热量对除湿溶液进行加热再生,室外新风经浓溶液除湿并经制冷剂冷却后,送入室内控制室内相对湿度。夏季供冷时,热泵系统和除湿系统共用1套制冷剂,达到同时实现室内供冷、除湿溶液再生和新风冷却的效果,保证室内舒适度及空气品质,避免室内结露。这种基于太阳能溶液除湿和金属毛细管网的新型辐射空调系统可实现室内温湿度独立控制,降低能源消耗,促进绿色建筑可持续发展。

Traditional air conditioning systems have a series of drawbacks such as hair blasting,cold surface mold,and low energy efficiency.In order to solve these problems,a radiant heat pump system based on metal capillary tube is proposed in this paper.The metal capillary installed in the building envelope is used as the indoor side heat exchanger,and the building integrated radiant heat pump system is used to control the indoor temperature.However,the capillary tube air conditioning system cannot guarantee the supply of fresh air,and there will be problems such as indoor condensation.Therefore,the paper proposes that the system can operate the solar energy solution dehumidification fresh air system,and use the heat collected by the solar collector plate to heat and regenerate the dehumidification solution.The outdoor fresh air is dehumidified by the concentrated solution and cooled by the refrigerant,and then sent to the indoor control room for relative humidity.In the summer cooling condition,the heat pump system and the dehumidification system share the same set of refrigerants,achieving the effects of simultaneous indoor cooling,dehumidification solution regeneration and fresh air cooling,ensuring indoor comfort and air quality,and avoiding indoor condensation.This new type of radiant air conditioning system based on solar solution dehumidification and metal capillary tube can achieve independent control of indoor temperature and humidity,reduce energy consumption and promote the sustainable development of green buildings.
