    S3：检测室内温度t和室内外温差△t，室内预设温度最大值为t1，室内预设温度最小值为t2，室内外预设温差为t3，比较t、t1、t2，且同时比较△t、t3，根据比较结果选择新风热交换空调系统的运行模式，具体选择如下：
    当t≥t1且△t≥t3时，启动新风热交换器(4)以及启动空调(5)制冷模式；
    当t≥t1且△t＜t3时，单独启动空调(5)制冷模式；
    当t≤t2且△t≥t3时，启动新风热交换器(4)以及启动空调(5)制热模式；
    当t≤t2且△t＜t3时，单独启动空调(5)制热模式；
    当t2≤t≤t1且△t＜t3时，不启动新风热交换器(4)和空调(5)；
    当t2≤t≤t1且△t≥t3时，启动新风热交换器(4)，不启动空调(5)；
    保持步骤S3循环进行。
  3. 根据权利要求1或2所述的新风热交换空调系统控制方法，其特征在于：在检测室内温度t和室内外温差△t并分别与对应预设值比较之前，先预设室内预设温度最大值t1、室内预设温度最小值t2以及室内外预设温差t3，24℃≤t1≤28℃，12℃≤t2≤18℃，6℃≤t3≤60℃。
  4. 根据权利要求1或2所述的新风热交换空调系统控制方法，其特征在于：在选择新风热交换空调系统的运行模式时，通过主机控制器(1)控制运行模式的切换。
  5. 一种用于实现如权利要求1至4中任一项所述控制方法的空调系统，其特征在于：包括主机控制器(1)、室外温度传感器(2)、室内温度传感器(3)、新风热交换器(4)、空调(5)、新风管道(6)、排风管道(7)、送风机(8)和排风机(9)，所述新风管道(6)和排风管道(7)布设于空调(5)内，新风管道(6)和排风管道(7)均经新风热交换器(4)连接至室外，所述送风机(8)设于新风管道(6)的送风口处，所述排风机(9)设于排风管道(7)的出风口处，所述室外温度传感器(2)设于室外，室内温度传感器(3)设于室内，所述室外温度传感器(2)、室内温度传感器(3)、送风机(8)和排风机(9)均与主机控制器(1)电连接且主机控制器(1)控制切换空调系统的运行模式。
