FLUID SUPPLY SYSTEM Russian patent published in 2018 - IPC F24D17/00 

FIELD: pipelines.

SUBSTANCE: invention relates to the fluid supply system. System comprises the hot fluid centralized supply pipeline, the fluid centralized return pipeline, cold fluid centralized supply pipeline, at least one local hot fluid pipeline, two or more heat exchangers and the hot fluid pump, wherein at least one heat exchanger contains the primary side, through the primary inlet connected to the hot fluid centralized supply pipeline and through the primary outlet to the fluid centralized return pipeline, at that, at least one heat exchanger contains the secondary side, through a secondary inlet connected to the cold fluid centralized supply pipeline, and through the secondary outlet to the hot fluid local pipeline, at that, at least one hot fluid local pipeline is connected to at least one local fluid outlet for the heated fluid supply from the connected heat exchanger secondary outlet, wherein the hot fluid pump is configured to be activated upon detection of the need for hot fluid. Through its respective primary inlet each heat exchanger is connected to the hot fluid centralized supply pipeline, through its corresponding primary outlet is to the fluid centralized return pipeline, through its respective secondary inlet to the cold fluid centralized supply pipeline, and each through its respective secondary outlet is to the respective hot fluid local pipeline, at that, the hot fluid pump is located in the fluid centralized supply pipeline, providing the hot fluid supply to all connected heat exchangers, wherein the hot fluid pump is configured to be activated during the fluid removal on one of the fluid outlet nodes, at that, the fluid supply system contains two or more heat exchangers, wherein each heat exchanger through the corresponding secondary outlet is connected to the other hot fluid local pipeline, at that, in the of cold fluid centralized supply pipeline the fluid removal detection at one of the fluid outlet nodes main sensor is located.

EFFECT: this enables to simplify the installation and maintenance.
