Rational installation choice of heat pump outer duct

Problem statement. The use of renewable energy sources by the world community is considered as one of the most promising ways to solve the growing problems of energy supply. The presence of an inexhaustible resource base and the environmental friendliness of renewable energy sources are their defining advantages. Given the significant potential of renewable energy sources in Ukraine, which is many times higher than the predicted levels of heat energy consumption, the withdrawal of alternative energy sources to a cost-effective level and the expansion of areas of use is an urgent issue of our time. Purpose of the article. is an in-depth study of alternative energy sources and methods for the efficient use of energy resources, followed by the selection of rational technology for constructing a heat supply system for a residential building based on geothermal energy sources. Analysis of recent research. According to the Organization for Economic Cooperation and Development (OECD), Ukraine has the highest level of utility costs in relation to income levels among European countries. The cost of Ukrainians to pay for housing is close to 40%, which is 1.6 times higher than the European average. To ensure a low level of energy consumption in energy efficient homes of the new generation, European countries use technologies that use geothermal energy through ground heat exchangers. However, this technology has not become widespread in Ukraine or enshrined in law. Therefore, the issue of introduction of technologies of ground heat exchangers at the expense of renewable energy sources is actual. Conclusion. The methods for arranging the external contours of the heat pump are considered and showed that the laboriousness of the device of heat exchangers in the horizontal circuit is almost 4 times lower than during drilling operations. The cost is also almost 4 times lower. Despite this, the developer will not always choose a horizontal heat exchanger, since for its construction it is necessary to provide a significant territory that cannot be given away for development or temporary, commercial buildings. In the case of tight construction conditions, an energy-efficient pile with a heat exchanger circuit will be acceptable.
