Solar Air Collectors for Cost-Effective Energy-Efficient Retrofitting
M.A. Paya-Marin, Queen’s University Belfast, Belfast, United Kingdom
Abstract
Solar air collectors (SACs) are a type of solar thermal collectors that use solar radiation to actively deliver warm air into buildings. Typically deployed onto surfaces of a building with a southerly aspect, the technology has a proven record and great potential as an available and cost-effective means of space heating. This chapter presents an economic study of both unglazed transpired solar air collector (UTSAC) and back-pass solar air collector (BPSAC) systems, taking into account the internal rate of return and installation cost, based on large-scale test setups and measured performance ...
