<p>PROBLEM TO BE SOLVED: To solve the problem raised by the conventional economizer control that at least an initializing function is available, because the selection of the openings of an outdoor-air taking-in damper and a return damper is regularly corrected, but the operating time of a compressor becomes longer and no sufficient energy-saving effect is exhibited, because no followup ability is available to the subsequent load fluctuation. SOLUTION: When the value obtained by subtracting the temperature of outdoor air from a set room temperature exceeds a preset value, the air- conditioning by means of an air conditioner is controlled by regularly adjusting the openings of the outside-air taking-in damper and return damper without operating the compressor.</p> |
