Abstract
Today, with the increased popularity and availability of renewable energy sources the question of ensuring a proper household heating, that is energy, is not as complicated as it used to be. Users are embracing the environmental sustainability stand and are turning to heat pumps and solar panels as means of providing heat for their homes. The geothermal heat pump and solar thermal panels energy efficiency rates coupled make these the perfect choice for those, who are concerned about the impact they make on the environment-aspiring to zero emission buildings. The combined system of solar thermal panels and ground source heat pump for heating capacity 13 kW will be developed. The main novelty is the investigation of a new type of a solar thermal accumulation tank. Hypothetically this solar assisted ground coupled heat pump system should reach COP rate 4 and reduce electricity demand consumption by 40%. To find out the truth of proposed thesis, the research will be carried out. Both simulation and real-life object data analysis will be performed. As a result, the potential of such a system in northern latitudes will be determined.
Highlights
As regarded the reduction of CO2 in the energy sector and the introduction of the concept of passive buildings in the building sector, different alternative heating solutions should be explored and their usefulness increased
There are numerous studies about utilization of solar energy in solar assisted systems and mainly with heat pumps. [3, 4] in their study, a solar assisted heat pump (SAHP) heating system powered by flat plate collector is compared energetically and financially with a conventional heat pump system for various climates
The simulation is performed with TRNSYS, and study shows that the coefficient of performance (COP) of SAHP heating systems was found over 4 for cold climates; a very important result which indicates the use of this technology in difficult weather conditions
Summary
As regarded the reduction of CO2 in the energy sector and the introduction of the concept of passive buildings in the building sector, different alternative heating solutions should be explored and their usefulness increased. Country-specific climate in the northern latitudes provides a large proportion of energy consumption for heating and hot water needs, mainly in the period from October to April. While for solar thermal system, the highest efficiency rate (during the cold season) is limited to the January-March period, and the lowest between November and December. These two distinct heating systems complement each other in a quite productive manner. The simulation is performed with TRNSYS, and study shows that the COP of SAHP heating systems was found over 4 for cold climates; a very important result which indicates the use of this technology in difficult weather conditions. As a novelty of this paper is the study of innovative thermo solar tank filled with bioethanol
