夏热冬冷地区城市暖通空调季节划分
Seasonal division of HVAC in cities of hot summer and cold winter zone
摘要：
夏热冬冷地区具有高温高湿的共同性，又有明显的东、西气候差异。为了解夏热冬冷地区东、西区各城市间暖通空调季节的差异，通过分析东区代表城市南京和西区代表城市重庆的室外空气热湿状态及暖通空调季节转换的天气过程，发现东、西区城市暖通空调各季节间转换过渡期时间的早晚、长短及复杂程度并不相同。进一步分析发现，东、西区城市暖通空调运行调节的重点、难点及节能潜力较大的时段不同，东区城市是供暖季节前后的通风时段，西区城市是除湿、空调季节前后的通风时段。
Abstract：
The hot summer and cold winter zone has the common features of high temperature and high humidity, as well as obvious climate differences between east and west regions. In order to understand the seasonal difference of HVAC among the cities in hot summer and cold winter zone, analyses the thermal and humid states of outdoor air and the seasonal change of the representative cities of Nanjing in the east and Chongqing in the west, and finds that the transition period of HVAC in eastern and western cities is different from each other in terms of time, length and complexity. Further analysis shows that the key points and difficulties of HVAC operation and regulation in eastern and western cities as well as the time periods with great energy saving potential are different. The eastern cities are the ventilation period before and after heating seasons, while the western cities are the ventilation period before and after dehumidification and air conditioning seasons.
