Efficient Design of Solar Assisted Heating Systems for Multi-Family Houses

摘要

Hydraulic concepts for solar heat appliances to support heating and domestic hot water in multi-family houses(solar combisystems) are investigated and compared by means of simulations and hardware-in-the-loop tests. Theaim is to find best-practice solutions.The standard for new constructions of multi-family housing is a central buffer storage system with fresh waterstation, but hot water storage systems are also used. Hydraulic concepts found in market research are comparedconcerning their efficiency, costs and complexity. Solar combisystems with fresh water stations are not verycomplex, offer high energy savings and the lowest heat generation cost: 0,19 €/kWh. This makes it the bestpractice concept for solar combisystems in multi-family houses.
