建筑节能是节能减排的工作重点，开发节能环保型空调系统是实现建筑节能的重要一步。应用离子交换膜进行溶液吸收剂再生的吸收式空调系统克服了当前空调系统存在的缺点，不仅能效比高，而且对环境友好。采用混合溶液吸收剂会使基于离子交换膜再生的吸收式空调系统具有更好的性能，因此对混合溶液吸收剂离子交换膜再生的传质传热过程进行研究具有重要的理论意义与现实价值。针对目前缺乏相关研究工作的现状，申请者提出了研究混合溶液吸收剂离子交换膜再生过程的传质传热机理的项目课题，并提供了相应的研究方案。该课题将研究混合溶液吸收剂离子交换膜再生过程的传质传热规律；研究传质与传热间的耦合关系；研究离子交换膜再生能力与溶液吸收能力的匹配及对空调系统性能的影响。通过研究，有望建立混合溶液吸收剂离子交换膜再生过程的传质传热模型，揭示传质传热耦合的机理，优化基于离子交换膜再生的吸收式空调系统的性能。

Enery conservaion in buildings is important for developing low carbon economy. Energy-saving and environment-friendly air-conditioning system is crucial for realizing energy conservaiton in buildings. A new absorpting air-conditioning system is proposed to improve the traditional air-conditioning system. This new sytem uses ion exchange memebrane to regenerate absorbent, through which it improves the performance and takes good care of the environment. The application of mixed absorbent can further improve the performance of the new air-conditioning sytem. So it is important to expose its mass and heat transfer mechanism. However, there has been little work about it so far. Therefore, the applicants propose the project aiming at exposing the mass and heat transfer mechanism of the membrane regeneration of the mixed absorbent. The research plan focuses on the mass and heat transfer rules in membrane regeneration of mixed absorbent, the coupling mechanism of mass and heat transfer, the matching of regenration and absorption and their influence on the sytem performance. Through research, it is expected to develop the mass and heat transfer model of mixed-absorbent membrane regeneration, expose the coupling mechanism of mass and heat transfer and optimize the performance of the membranbe regeneration based absorption air-conditioning system.
