APPARATUS FOR CONTROLLING COOLING OF CONTROL PANEL FOR DIGITAL DIRECT CONTROL

摘要

PURPOSE: An apparatus for controlling cooling of control panel for DDC(Digital Direct Control) is provided to remove heat generated in the control panel of a blower control system. CONSTITUTION: An apparatus includes a dust removing filter(7) installed on a lowermost part of a control panel to collect dust contained in passing air; pipes(13,13a) installed to a lower part of the dust removing filter to supply air to an upper part of the control panel; a solenoid valve(8) controlling movement of air supplied from a blower(11) through the pipes; an upper part temperature detecting part detecting temperature of the upper part of the control panel; a filter temperature detecting part detecting temperature of the dust removing filter; a humidity detecting part detecting humidity in the control panel; a high selector comparing part using signal of the upper part temperature detecting part, the filter temperature detecting part and the humidity detecting part and comparing to determine whether exceeding set value; and a solenoid valve actuating part controlling air supply according to the comparing result.
