  • Patent number: 4914925
    Abstract: A control device for an air conditioner operable in the heating and cooling operation mode is disclosed, which device comprises a "too hot" and a "too cold" switch which is operated by the user when he feels that it is too hot or too cold in the room conditioned by the air conditioner. When a first operation of one of these switches by the user takes place, a mode selector automatically selects the operation mode of the air conditioner, and the control of the air conditioner is started immediately. The setting or target temperature is automatically renewed every time a further operation of one of the switches is made, so that the target temperature may be adjusted to the individual preference of the user. The fan speed of the air conditioner may also be modified according to the frequency of inputs through the switches.

  • Patent number: 4850203
    Abstract: In the air conditioning control apparatus of the present invention, the frequency determining means determines not only an operation frequency for the compressor depending on the load determined based on the detected room temperature and the set room temperature, but also an upper limit for the compressor operation frequency based on the air flow rate of the outlet air from the upper and lower outlet ports of the indoor unit and the successive operation time of the compressor. As a result, even if the compressor carriers out cooling operation under too great of a load, the temperature of the air blown off from the upper outlet port of the indoor unit is prevented from dropping down to less than a certain value, thereby eliminating economically the problem wherein dew is produced on the outer surface of the ceiling plate and so on.
