HEATING SYSTEM Russian patent published in 1998 - IPC

FIELD: thermal engineering. SUBSTANCE: introduced in system are heat storage, blower-separator with air ducts, electric heaters mounted in air ducts and coupled with blower-separator and fan air channel, first, second, and third controlled switches, temperature sensor, comparison unit, temperature setting element, and blower- separator stop sensor; outputs of sensor and temperature setting element are connected, respectively, with first and second inputs of comparison unit; inputs of electric heaters and electric motors are respectively connected through first, third, and second controlled switched to output of power supply; second inputs of controlled switches are connected to comparison unit output; third input of first controlled switch is connected to output of blower-separator stop sensor whose input is connected to blower-separator output; heat storage is coupled with air duct of fan and connected via gas duct to second output of heat exchanger. EFFECT: improved design. 1 dwg
