HYBRID OPERATING APPARATUS OF A REGENERATIVE HEATER AND HYBRID OPERATING METHOD OF A REGENERATIVE HEATER

摘要

The present invention provides a hybrid operation apparatus and method for a regenerative heater to improve the dehumidification performance and reduce energy by controlling the regenerative temperature of the regenerative heater according to various conditions. The hybrid operation device of the regenerative heater presented includes an absolute humidity detector for detecting the absolute humidity of the air supplied to the dehumidification rotor, a dew point temperature detector for detecting the dew point temperature of the air returned from the dry room, and a regeneration process in the dehumidification rotor. Regenerative exhaust temperature sensing unit for sensing the temperature of the exhaust air, operating the regenerative heater at the regenerative temperature corresponding to the detected absolute humidity, but comparing the detected dew point temperature with the set point and the detected regenerative exhaust temperature and the set regenerative exhaust temperature range A control unit for controlling the current regeneration temperature of the regeneration heater according to the comparison result, and a corresponding regeneration exhaust temperature when the regeneration temperature and the detected regeneration exhaust temperature corresponding to the detected absolute humidity are higher than the set regeneration exhaust temperature range. And a memory unit for storing the regeneration temperature of the regeneration heater set corresponding to the regeneration heater. Compared to the conventional method of operating at a constant regeneration temperature irrespective of indoor conditions, the regeneration heater is controlled at about 140 ° C. to 180 ° C. to reflect various conditions in the room, thereby improving dehumidification performance and maximizing energy saving efficiency.
