For performance survey of horizontal heat exchanger system on reference region it is necessary to predict underground temperature. As the underground temperature decision is difficult, numerous calculations are needed to decide temperature cycle. The phase shift decision in this paper is based on outdoor temperature, surface temperature and Buggs formula without phase shift.
