NEW SOLAR HEATED RESIDENTIAL AREA IN VALLDA HEBERG - INITIAL EXPERIENCES RELATED TO SYSTEM PERFORMANCE

Övrigt konferensbidrag, 2014

This paper describes a new residential building area with a solar assisted block heating plant. The building area comprises 26 single family buildings, four small multifamily buildings, 6 row houses and a nursing home for elderly people with 64 apartments. All buildings are designed for a low heat demand (<45 kWh/a.m2) and the total heated floor area is 14 000 m2. The block heating system comprises a central 250 kW wood pellet boiler, about 700 m2 of distributed roof-integrated solar collectors and a novel heat distribution system. An initial evaluation indicates that designed heat demands, as well as the overall system performance including expected solar contribution, is likely to be met. Reported measurements include annual (April 2013 – March 2014) heat balances for two substations with single family buildings and a monthly (March 2014) heat balance for the whole system.
