Title: Room regenerating system
Inventor: CHOI CHUL HO
IPC: F24J3/00
Filed: 1998-12-31
Abstract: PURPOSE: A room regenerating system is provided to regenerate a lot even with small amount of power in a large space by regenerating in an indirect regeneration method with the characteristic of thermal medium. CONSTITUTION: A temperature in a thermal conductive pipe is increased by heating in a range of -20°C to 120°C with an alternative direct conduction method. Then, a thermal medium(3) within the thermal conductive pipe electrically heats over the lines while being changed to an evaporating state from a liquefying state. Herein, the electrically heating speed of the thermal medium is about 24m/sec, and the heat is given to the thermal medium of the heat exchanger(4). Accordingly, the thermal medium inside the heat exchanger also starts to evaporate and heat-exchanges with the air contacting with the heat-exchanger. When the thermal conductive pipe is a wrinkled pipe type, the evaporation and the electrically heating speed of the thermal medium becomes fast so that the heat-exchange performance is accomplished as much as possible.
