Solar space heating systems using annual heat storage. Progress report, July 1, 1976--December 31, 1976

The assumptions made in the development of the computer simulation used for modelling annual storage solar heating systems are outlined. A vertical cylindrical storage tank is used with homogeneous soil properties and a water table and ground surface acting as sinks. The equations used are described in a general way. Report work done under the grant to date and approaches used to find optimum configuration is also included.
