The subject of this study is to improve the design of the condenser for an air heat pump system in order to increase the heat exchange of the walls of the collectors (torus) and condenser pipelines with water for the heating circuit and to reduce the energy consumption for its operation. The emergence of the need to improve the existing models is due to the fact that the use in some cases of devices based on Venturi tubes and vortex tubes with reagent supply coaxially or tangentially does not give the desired positive effect. When their geometric parameters change, a decrease in the hydraulic resistance of the fluid and the volume of the working fluid leads to new configurations of the device. In our proposed device, the effect is achieved by reducing the total hydraulic resistance, increasing the efficiency of the heat pump system in a wide temperature range using condensers containing collectors (tori) and a container around the straight-pipe apparatus, where the straight-pipe apparatus together with the container represents a single structure of the “pipe in pipe”.
