PLANT FOR USING POWER TRANSFORMER EXCESS HEAT Russian patent published in 2004 - IPC

FIELD: using excess heat of power transformers.

SUBSTANCE: transformer cooling device 6 is connected to first pipeline 7 to ensure circulation of first fluid coolant between transformer and heat pump 5 for heat transfer to evaporator 10 inserted in heat pump and connected through second pipeline 11 carrying second fluid medium to compressor 12, condenser 13, and expansion valve 14; there is third pipeline 15 carrying third fluid coolant to transfer heat to at least one heat-consuming module 16 connected to condenser 13. There is also fourth pipeline 19 communicating directly or indirectly with first pipeline 7 and partially brought out to rock, earth, and/or water, to heat storage and radiator assembly 20; multipass valve 23 affording transfer of excess heat from transformer through first pipeline 7 either to heat-pump evaporator 10 or to mentioned heat storage 20, or to radiator is disposed between first and fourth pipelines.

EFFECT: enhanced cooling effectiveness and economic efficiency due to using excess heat energy of power transformer.
