Title: Controller for air conditioner
Inventor: SATO KOICHI
IPC: F25B47/02
Filed: 2000-10-18
Abstract: PROBLEM TO BE SOLVED: To improve energy saving property by providing a simple constitution without employing any humidity sensor or the like and improving an operating efficiency upon controlling defrosting operation in an air conditioner (room air conditioner). SOLUTION: Heating operation is effected under a heating mode by controlling the switching of a flow passage switching valve 100 and the operating time of the heating operation is counted. When the heating operation time has exceeded a heating operation set time (defrosting operation prohibiting time) and the decision of defrosting is satisfied, the defrosting operation is effected. Upon the defrosting operation, the temperature Tc' of an outdoor heat exchanger 9B is detected by a temperature sensor 403. The temperature Tc' is monitored whether the same is in the proximity of a freezing point (0 deg.C) or exceeds the freezing point or the same has arrived at a heating resetting temperature or not. Further, a defrosting operation time is measured.  In this case, when temperature stays longer around the freezing point than that of a previous time, a heating operation setting time is set so as to be short. When the temperature stays around freezing point shorter than that of a previous time, the heating operation set time is set so as to be long.
