Research on new air conditioning and ventilation mode of boarding bridge in western airport

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.
