Abstract
Analysis of the application of combined solar-assisted accumulation ground source heat pump system for heat supply of the building
Highlights
Due to the energy crisis, it is becoming necessary to increasingly using of unconventional energy resources, and the most applicable are solar energy and heat pumps
The scheme consists of three circuits passing through the storage tank, which allows them to hydraulically decouple from the implementation of heat exchange, as well as the contour of the vertical ground collector
In the cold period of the year, heat accumulates in the storage tank through using of insolation heat and renewable heat of the soil with the using the heat pump
Summary
Due to the energy crisis, it is becoming necessary to increasingly using of unconventional energy resources, and the most applicable are solar energy and heat pumps. Solar collectors in combination with heat pumps of various types and designs allow to organize the heat supply of residential, industrial and administrative buildings, as well as provide them hot water. At the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine, has been established and is being developed a Center for Heat Pump Technologies in which are being carried out the studies of energy and economic efficiency of using solar assisted ground source heat pump heating systems. The authors conducted an appraisal technical and economic analysis of the financial costs of using a combined solar assisted ground source heat pump system for heating the building and comparing its energy efficiency with the traditional heat supply system during different tariffs for natural gas
