In designing the underground air conditioning, it is desirable to estimate the underground temperature and humidity that will be obtained after the air conditioning is operated, but the strict calculation of them is very difficult and too troublesome for practical purpose. The authors have studied on this problem for several years, The present paper describes the method of estimation, proposed by authors, which is obtained by summarizing the results of analysis recently carried out as well as already published and the results of measurement of underground temperature and humidity carried out over a long period of time.
