Abstract:
1. A hybrid operating apparatus of a regenerative heater, the apparatus comprising: an absolute humidity sensing unit configured to sense an absolute humidity of air supplied to a dehumidifying rotor; a dew point temperature sensing unit configured to sense a dew point temperature of air returned from a dry room; a regeneration exhaust temperature sensing unit configured to sense a temperature of exhaust air regenerated in the dehumidifying rotor; a control unit configured to operate the regenerative heater to a regeneration temperature corresponding to the sensed absolute humidity, wherein the control unit controls a current regeneration temperature of the regenerative heater according to a result obtained by comparing the sensed dew point temperature with a setup value and a result obtained by comparing the sensed regeneration exhaust temperature with a set range of regeneration exhaust temperature; and a memory unit configured to store the regeneration temperature of the regenerative heater, set to correspond to a corresponding regeneration exhaust temperature when the regeneration temperature of the regenerative heater, corresponding to the sensed absolute humidity, and the sensed regeneration exhaust temperature are higher than the set range of regeneration exhaust temperature, wherein the setup value is a value previously set in the control unit.
