DESIGN AND ANALYSIS OF A PASSIVE SOLAR HEATING SYSTEM WITH A HEAT PUMP AND A LONG TERM HEAT STORAGE FOR AN OFFICE BUILDING
In recent years the so-called "passive" solar heating systems have been studied extensively in many different climates. One of the conclusions which have emerged from these studies, is that in general passive systems are not able to store the collected energy for more than about twelve hours. The heating system presented in this paper, is a system which consists of a passive direct gain system, a heat pump and a large heat storage. It has been designed for an existing well insulated building to which a light-weight sunspace was attached. The sunspace which is thermally isolated from the building, is not heated during the night, but is kept within the comfort zone during office hours. The heat pump and the large storage enable an enhanced control of the direct gain system and the storage of the excess heat of the passive system over long periods of time. The system which is actually under construction has been analyzed with a model and very promising results have been obtained so far. Very high solar fractions seem possible (80%). A detailed monitoring is planned for the heating season 1986 - 1987.
