Solar heating with seasonal storage (shss) prrefeasibility study

摘要

Large annual solar fractions are possible with full capacity of active thermal collectors for room heating and DHW with seasonal storage. Urban housing schematic designs studied with heat load ranges include: townhouses (100 units) and apartments (3,45, and 10 story). Performance and economics are predicted with Seasonal.EES software for Madison, WI. Annual solar fractions of 82percent and 75percent resulted for a 3-story 138 apartment complex with 3.5 BTU/ft~(2-)FDD room heating and 21,600 liters/d DHW, with rooftop flat-plate liquid collectors (tauAlpha_n =.88 and .76) (3620m~2/38,965ft~2), and insulated cylindrical water storage tank (8482m~3/2.24 milgals). Influence of solar heating with seasonal storage (SHSS)(aka CSHPSS) to cold-grey climate big city building/urban sustainable design is discussed.
