Development of solar air heaters; Udvikling af luftsolfanger

Abstract

The development of the design for a new type of solar air heater (a type of solar collector based on air as the medium for heat transfer) which could compete with solar collectors based on liquids is described in detail. The advantages of this system are that the design is simple and cheap, there are no risks in relation to frost, boiling or damage to buildings by leakage and it is suitable for use as a low temperature source for low temperature buildings. The system has a longer service life and needs less maintenance. Information was derived largely from sources outside of Denmark and an evaluation of commercial products, thermal theories, materials, laboratory tests etc. It is concluded that the efficiency of solar collectors based on air and those based on liquids is about the same. Air-based systems are especially suitable for direct space heating at low temperatures and can be integrated as a facade component, in which case their use must be taken into consideration at the architectural planning stage. This type of solar collector could also be used to collect waste heat from industrial processes, for preheating ventilation air and in closed systems where heat exchangers are used  More>>

This type of solar collector could also be used to collect waste heat from industrial processes, for preheating ventilation air and in closed systems where heat exchangers are used for exchange to hot water. Leakage must be avoided to minimize electricity consumption related to ventilators. Standard components are recommended for these systems. Air based solar collectors would be suitable for glass structures. (AB)}
