The work was performed to provide potential users of soil warming systems with some general guidelines for the design of a soil warming installation. Although a detailed design is not included, the general configuration of such a system is discussed. A computer program that solves the equations governing heat and water transfer in soils was used to simulate the operation of a soil warming system composed of a series of buried pipes at uniform spacing and depth carrying warm water. The results included temperature and moisture content distributions for various soil warming system pipe spacings and depths and for varying weather conditions. Annual temperature cycles are presented for Portland, Oregon; Athens, Georgia; and St. Paul, Minnesota; for soil with no heating; and for soil with a continuously operating soil warming system.
Includes bibliographical references (pages 29-30).
