解析

本题考查学生对对话内容的理解，特别是关于空调发明的关键信息。解题核心在于抓住对话中提到的发明者、时间及相关细节。需注意选项中容易混淆的时间点（如发明时间与普及时间）以及发明者与实际贡献者的对应关系。

选项分析

关键信息：对话中明确提到空调的发明者是Willis Carrier，而其他选项中的时间点或描述存在错误。

  • 选项C正确，因Willis Carrier是空调发明者的常识性信息。
  • 选项A错误，空调发明时间早于二战（1902年发明，二战为1939-1945年）。
  • 选项B错误，1902年空调最初用于工业（如印刷厂），家庭普及较晚。
  • 选项D错误，发明后需时间改进和推广，未立即普及家庭。
