AIR TEMPERATURE CONTROL APPARATUS IN ROOM Russian patent published in 2005 - IPC

FIELD: automatic control systems, namely controlling air temperature in rooms heated by means of open heat supply systems.

SUBSTANCE: apparatus is designed for controlling air temperature in room heated by means of open heat supply system having circuits of common and secondary circulation with direct and reverse main lines. Each circuit includes circulation pump with drive unit and revolution number regulator. Main line of pump of secondary circulation circuit is connected with outlet of pressure controller and main line of pump of common circulation circuit is connected with outlet of air temperature controller. Apparatus also includes pickup for detecting temperature of reverse heat transfer agent at outlet of heating system. Heat quantity meter is mounted at outlet of circulation pump of direct main line of common circulation. Flow rate meter of heat transfer agent is mounted at outlet of circulation pump of secondary circulation circuit.

EFFECT: enhanced effectiveness of apparatus, lowered flow rate of heat transfer agent of common circulation circuit at maximum use of energy potential of heat transfer agent and increased flow rate of heat transfer agent of additional circulation circuit, optimal heat consumption and electric energy cost in drive units of pumps.
