Description

Description: TECHNICAL FIELD The present invention relates to the operation of an air conditioner for improving comfort of an air-conditioned space by continuously performing air conditioning of the air-conditioned space for 24 hours. The present invention relates to a control device.

Conventional technology Conventionally, one of the operation control means for controlling the operation of the air conditioner, to minimize the air conditioning capacity of the air conditioner,
It was common practice to provide an air-conditioning mode that allows continuous operation.

In addition, the rotation speeds of the compressor and the indoor blower are controlled according to the heat load.

However, this type of air conditioning mode has been positioned as one of the air conditioning modes of the operation control means. That is, even in the operation control device for an air conditioner equipped with this type of air conditioning mode, the air conditioning mode must be set in the operating state by the operation control means that performs "operation" and "stop" control. I can't choose. (JP-A-53-
53146 and Japanese Patent Laid-Open No. 59-0487) FIG. 13 shows one of the conventional operation control means for controlling the operation of the air conditioner, which minimizes the air conditioning capacity of the air conditioner. It is a flow chart which shows one Example of the operation control device of the air harmony machine which provided the air-conditioning mode which suppresses and continues operation continuously.

According to FIG. 13, starting from START, first, if the selection of “operation” by the operation control device is N (step
101), stop all operations of the air conditioner (step 10)
2). If Y, the process proceeds to the next STEP, and if the selection of the continuous operation air conditioning mode by the selecting means is Y (step
103) Proceed to the continuous operation air-conditioning operation mode (step 10
If 4) and N, the operation is performed in the normal load-corresponding operation mode (step 105).

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional operation control device, when the stop is selected, the air conditioner stops all the operations, and the operation control device continuously operates the air-conditioned space. In order to improve the comfort of the air-conditioned space while maintaining the air conditioning, it is necessary to always select the air conditioning mode while keeping the selection by the operation control means "operating". As described above, if the air conditioning capacity of the air conditioner is suppressed to the minimum by the selection mode, as a result, the air conditioning of the air-conditioned space can be maintained with less energy consumption, but for the user, always, It is uneconomical that the air conditioner is in the "running" state.

Further, in the control in which the operation control of the air conditioner is governed by such an operation control device, when the user leaves the room while wishing continuous operation,
The operation (operation, stop operation) that is used well in daily life causes the selection of the operation control means to be “stop”, and the desired continuous air conditioning may be interrupted.

Furthermore, if the operation is interrupted as described above,
Before restarting the operation, the room temperature will rise during cooling and will decrease during heating, so it will take a very long time to restart when restarting, for example during heating. There is a problem that it is significantly damaged and also costs electricity.

The present invention has been invented with respect to such a point, and if the air conditioning mode of continuous air conditioning, which is desired by the user, is selected once, after this selection, the intermittent operation up to that point is intermittent. It is an object of the present invention to provide an operation control device for an air conditioner that can obtain continuous air conditioning even if the air conditioning operation is stopped.
