EVAPORATIVE CIRCUIT FOR GROUND SOURCE HEAT PUMP Russian patent published in 2021 - IPC F24T10/15 

FIELD: obtaining or using geothermal heat.

SUBSTANCE: invention relates to the field of obtaining or using geothermal heat and can be used in ground circuits of geothermal heat pumps, in evaporative systems of geothermal heat pumps of direct heat exchange, in heating and cooling systems, including air conditioners, refrigeration plants using freons as a heat carrier. The evaporator circuit of the ground source heat pump is made of high temperature polyethylene PE-RT, and the collector tube diameter is 16 mm. The element that connects the inlet and outlet pipes with a system of collector pipes is a distribution header. Its central part is a cylindrical pipe segment plugged at one end. Three pipes are symmetrically connected with both sides of the cylindrical pipe segment. Each pipe is connected to a collector pipe. The connection of the inlet or outlet pipe with the open end of the distribution header and the connection of the distribution header pipe with the collector tube are made by means of socket welding. Disclosed is a method for the location of the earthen contour of a geothermal heat pump of direct heat exchange, in which the collector pipes are placed horizontally in the soil in 6 parallel planes in a trench 3 m deep below the freezing point of the soil at a distance of 0.5 m from each other, the end sections of the inlet and outlet pipes, connecting elements , the inlet and outlet pipes of the evaporation circuit of a geothermal heat pump with a system of collector pipes and the initial sections of the collector pipes are located in a caisson well.

EFFECT: invention is aimed at obtaining and using geothermal heat.
