西部机场登机桥新型空调通风方式
Research on new air conditioning and ventilation mode of boarding bridge in western airport
摘要：
机场登机桥存在夏季过热、冬季热舒适不佳、传统机械制冷能耗高、空调系统及其配套电源初投资大等问题。基于西部高原严寒地区气候特征及登机桥特点，提出了夏季采用蒸发冷却（方案1）与屋面空气夹层（方案2）、冬季采用零辅助热源太阳房方式的方案。结合屋面空气夹层与零辅助热源太阳房方案，提出新型登机桥空调通风方式。结果表明，方案1降温15 ℃，方案2技术经济性最好；在满足基本热舒适要求前提下，新型空调通风方式初投资为常规空调的10%，运行费用为常规空调的50%。
Abstract：
There are some issues in airport boarding bridge, such as overheating in summer, poor thermal comfort in winter, high energy consumption of traditional mechanical refrigeration, large initial investment in air conditioning system and its supporting power supply. Based on the characteristics of climate and boarding bridge in the severe cold area of the western plateau, it is proposed to adopt evaporative cooling (scheme 1) and roof air interlayer (scheme 2) in summer and zero auxiliary heat source solar house in winter. Combined with the second scheme and zero auxiliary heat source solar house, a new type of boarding bridge air conditioning and ventilation is proposed. The results show that scheme 1 reduces the temperature by 15 ℃ and scheme 2 has the best technical economy. The initial investment of the new air conditioning and ventilation mode is 10% of that of conventional air conditioning and the operation cost is 50% of that of conventional air conditioning on the premise of meeting the basic thermal comfort requirements.
