ENERGY VECTORS INTEGRATION FOR SYSTEM AND CUSTOMER BENEFITS AT A RESIDENTIAL HOUSEHOLD
Abstract
The paper presents an experimental pilot research, for the study of the integration of the electrical energy vector from a primary regenerative source with the thermal energy vector, for the purpose of residential air conditioning. The research referred to a period with the lowest ambient temperature. Furthermore, the research aims to highlight the economic problems for a local scale (residential heating) when using thermal energy produced by a heat pump with consumption and electricity produced with the help of own photovoltaic panels. The experimental part includes a residential heating installation with radiators (with domestic water supply) equipped with a heat pump with a power of 15kW. Climate variation within a calendar year will lead to both variation in self-produced electricity and residential heat consumption, with global optimization being the main objective of the research. The proposed energy system will contribute to the reduction of emissions specific to the combustion of fossil fuels. The use of electricity from the grid leads to an increase in the cost of thermal energy compared to the case of using natural gas for the coldest periods of the year. However, the extension of the calculations for the entire residential heating period will lead to a significant increase in the proportion of thermal energy produced from its own renewable source, which will also be reflected in the costs. The data resulting will contribute to the creation of a database regarding the introduction of residential air conditioning with heat pumps in the city of Bucharest, geographically located in the temperate continental climate zone (average annual temperature being ).
