GEOTHERMAL POWER PLANT MODULAR POWER UNIT Russian patent published in 2021 - IPC F24D15/00 F24T50/00 F03G4/00 

FIELD: heating and hot water supply systems.

SUBSTANCE: invention relates to heating and hot water supply systems for residential, office and industrial premises, as well as the production of electrical energy due to - mainly - the low-potential thermal resource of thermal sources. The modular power unit includes a thermal-mechanical converter, in which a thin-walled tube is at the same time its drive shaft, which transfers rotation to an electric generator through a multiplier. In the middle part, the pipe is reinforced with a sleeve in contact with a thrust roller during temperature bending of the pipe. The lower pipe segment is located in a groove connected to the thermal flow channel. There is a similar chute at the top, which forms a channel for the cooling air flow. The compressor unit provides additional heating of the thermal flow by recuperating the heat taken from the cooled pipe segment. The rest of the heat can be used in heating systems and hot water supply.

EFFECT: invention ensures high efficiency of work on low-potential thermal springs with a relatively simple design.
