Hence, on the whole, the radiant system proved to be more energy-efficient than the convective system, even when the radiant system consumed 25.6% more energy for pumping and about four times more energy for the boiler. 2. Research Methodology 2.1. Literature Review This study is conducted ...
The reference version of the LCC analysis for the first group of technologies uses a gas condensing boiler. It is one of the two most used heat sources in residential buildings (the other one being district heating). In this version, a central boiler room with two boilers in series with a...
of a hybrid solar-biomass system for heating, cooling, DHW, and electricity production consisting of evacuated tube solar collectors with thermo-electric generators, a cascade sorption-compression heat pump that can work in reverse mode as an ORC (Organic Rankine Cycle) and a biomass boiler. Resul...
Figure 2. A technological diagram of the research installation. Objects A5 and A6 are gas boiler houses with installed DHW heaters (3 × 750 ddm3m3) providing partial accumulation of domestic hot water. Each boiler house supplies three residential buildings. The installation of hot utility water...
In cooperation with a condensing gas boiler, in terms of the energy performance of the building. A diagram of the energy flow of the discussed solution in comparison to the installation without a heat pump is presented in Figure 1. 2. Materials and Methods 2.1. Climatic Data The analyses pre...
