This article is devoted to the methods for perfection of energy, economic factors, environmental factors and work modes of the ground source heat pump systems with the account of climate
conditions. The purpose of the work is to predict and prevent freezing of the soil during long term of
exploitation of the low-power and high-power ground source heat pump systems for justifying rational
conditions of implementation GSHP in Ukraine and South-East Regions of Europe. This goal is
achieved by solving the following problems: determining the energy-economic and environmental factors based on considering the work modes of the ground source heat pumps; evaluation of the operating efficiency of ground source heat pump systems based on minimizing fuel consumption and greenhouse gas emissions; perfection of solutions enable implementation of ground source heat pumps
friendly to the environment and justifying rational conditions of implementation the ground source
heat pumps for residential sector. The important results of the work are the obtained and analyzed data
on the influence of energy and economic factors both environmental criteria on the work modes and
scheme-constructive solutions of ground source heat pumps. Modeling of heat exchange processes in
the soil around the soil tube shows that in order to avoid freezing of the soil, the minimum permissible
specific number of vertical tubes should be at least 0.12–0.15 pieces/m2
of heated area. The significance of the results consists in the possibility of using the results of numerical simulation for preventing freezing of the soil around ground pipes of the ground source heat pump systems.
