<p>PURPOSE:To make an odor given out in time of stoppage in a cooling action eliminable in an effective manner, by operating an adjusting device as long as for the specified duration as the cooling action of a heat exchanger stops, while letting a deodrant or an aromatic send forth its odor thereabout. CONSTITUTION:When a main switch 11 is turned on, a relay 5 is intermittent by a control amplifier CA, turning on a compressor coupling clutch MgC in a refrigerant cycle as a contact 5a of the relay 5 is closed, and cooling at a heat exchanger 1B takes place. Next, when the relay 5 is switched over and its contact 5b is closed, a cooling action comes to a stop while a delay circuit 6 is set in motion, and a transistor 8 is turned on with the output of a comparator 7 till charging voltage 7a from a CR time constant circuit 6a reaches reference voltage 7b, for example, 10sec long, exciting a solenoid valve 9 and opening an on-off plate 4 via a disphragm actuator 10, thus a deodrant 3 inside an auxiliary box 2 is contacted with passing air inside a ventilating duct 1 and any odor out of the heat exchanger 1B is eliminated.</p> |
