Abstract
An important area of energy conservation is the use of energy efficient heat supply systems. Such systems are systems with heat pumps to utilize the low-potential heat of the upper layers of the earth's crust. The urgent scientific task is the development of designs of heat pumps to increase their efficiency. The distribution of heat pumps is acquired on the basis of vertical ground heat exchangers, with the promising implementation of these heat exchangers in the form of building piles, so-called power piles. The issue of their interaction is very important when designing heat pumps based on power piles, since the structural and bearing capacity establishes certain boundaries for the separation of foundation piles. Research of vertical soil heat exchangers is a popular theme of scientific developments, in particular, the most profound studies are conducted in the USA. Also, Belarusian specialists are specifically involved in the modelling of energy piles. Finnish companies make a major contribution to the development of geothermal energy based on power piles. The article deals with the systems of heat supply with a soil heat pump, which used as a evaporator building foundation piles, so-called power piles. The robots have constructively developed energy parameters of energy fingers. Considered basic working parameters: the number of U-piping tubes in the design of the piles; tube diameter; crock between piles; heat supply of the piles; distance between piles. Well-known studies on the design features of power piles and their impact on the energy performance of heat pumps are analysed. It was established that the least investigated area in this field is the method of engineering calculations of energy piles, namely, the mutual influence of energy piles one by one, that is, the minimum allowable distance between the foundation energy piles. For the mass implementation of power piles in the new construction, a scientifically sound method of selecting the optimal structure of the foundation energy piles is necessary
