摘　　要：地冷空调使用天然可再生的土壤冷源,在夏季某些室外条件下可为房间供冷,但室外温湿度很高时,独立的地冷空调系统无法满足空调舒适度标准。本文中提出一种新型地冷耦合除湿型空调系统,在地冷系统前耦合吸附器对空气预除湿,并在不同的室外条件下,对独立地冷空调和地冷耦合除湿型空调系统进行了热力学分析和对比。结果表明相对于独立的地冷空调,地冷耦合吸附除湿型空调系统的性能和可靠性提高。An independent earth cooling system worked well for space cooling in summer mainly using renewable ground heat sink in some outdoor air conditions. But for hot climates, earth cooling air may not meet comfortable air conditioning standard. Thus a new air conditioning system, i. e. , earth cooling system combined with adsorption dehumidifier was presented in this paper. An adsorption dehumidifier was coupled before earth cooling system to dehumidify air beforehand. Thermodynamic analysis was also made for comparison of the performance of the systems with or without adsorption dehumidifier on different outdoor air conditions. Results show that the performance and reliability of the earth cooling combined system with adsorption dehumidifier are greatly improved as compared with the independent earth cooling system.
