SYSTEM, LAYOUT AND METHOD FOR HEATING AND COOLING Russian patent published in 2022 - IPC F24D11/02 

FIELD: heating.

SUBSTANCE: invention relates to a system, layout, and method for heating and cooling multiple rooms of a building or buildings. Heating and cooling system for air conditioning of multiple rooms of a building, containing a secondary heat network for circulation of a secondary working fluid, wherein the secondary heat network comprises a feeding line for circulation of a high-temperature secondary working fluid and a return line for circulation of a low-temperature secondary working fluid; two or more connecting lines provided in the secondary heat network, wherein each connecting line extends between the feeding line and the return line and is configured to interconnect the feeding line and the return line; two or more primary heat exchangers located in two or more connecting lines and configured to provide a primary heat exchange connection between the secondary heat network and the room of the building; and a geothermal heat exchanger located in connection with the secondary heat network. The geothermal heat exchanger comprises a geothermal network with an ascending pipe and a drain pipe, wherein the ascending pipe is located inside the drain pipe, and the ascending pipe of the geothermal heat exchanger is equipped with first heat insulation surrounding the ascending pipe and extending along at least part of the length of the ascending pipe from the surface of the ground, and the heating and cooling system comprises a first pump configured to control the geothermal heat exchanger in the heat extraction mode, wherein the secondary working fluid circulates downwards in the drain pipe and upwards in the ascending pipe, and a second pump configured to control the geothermal heat exchanger in the heat supply mode, wherein the secondary working fluid circulates downwards in the ascending pipe and upwards in the drain pipe.

EFFECT: provided system for heating and cooling, layout and method for heating and cooling multiple rooms of a building or buildings with structural simplification.
