摘要：
The thermophysical properties of various types of soils depend on dry bulk density, water content and mineral components. The time dependent temperature distribution of the undisturbed ground is presented. The energy required from the ground to heat a dwelling is determined from the demand, the ratio of heat exchange area in the ground to heated area of house, the coefficient of performance of the heat pump installation and the time dependent outdoor temperatures, From these quantities the brine temperatures in the heat exchanger pipes are calculated for various types of soils, depths and centerline distances at which the pipes are installed. These brine temperatures must be adjusted in order that the required amount of heat be transferred from the ground to the brine during the heating period.
