Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the operation of an air conditioner whose purpose is to improve the comfort of an air-conditioned space by continuously air-conditioning the air-conditioned space 24 hours a day. This relates to a control device.

BACKGROUND OF THE INVENTION Conventionally, one of the operation control means for controlling the operation of an air conditioner is an air conditioning mode in which the air conditioning capacity of the air conditioner is minimized and the operation is continued continuously. It was well done.

Additionally, the rotational speed of the compressor and indoor blower has been controlled in accordance with the heat load.

However, this type of air conditioning mode has been positioned as just one air conditioning mode among operation control means.

In other words, even in the operation control device for an air conditioner equipped with this type of air conditioning mode, the air conditioning mode cannot be changed unless the air conditioner is put into operation by the operation control means that performs "start" and "stop" control. I can't choose. (Unexamined Japanese Patent Publication No. 5
3-53146, Japanese Patent Application Laid-open No. 59-0487)
Figure 13 shows that one of the conventional operation control means for controlling the operation of an air conditioner is an air conditioning mode that minimizes the air conditioning capacity of the air conditioner and maintains its operation continuously. It is also a flowchart showing an embodiment of an operation control device for an air conditioner.

According to FIG. 13, starting from 5TART, first, if the selection of "operation" by the operation control device is N (step 101), all operations of the air conditioner are stopped (step 102). If Y, the process moves to the next 5TEP, and if the selection of the continuous air conditioning mode by the selection means is Y (step 103), the process proceeds to the continuous air conditioning mode (
Step 104), if N, it operates in the normal load corresponding operation mode (Step 105).

Problems to be Solved by the Invention In such a conventional operation control device, when stop is selected, the air conditioner stops all operations, and this operation control device continuously controls the air conditioned space. In order to improve the comfort of the air-conditioned space while maintaining the air conditioning of the air conditioner, it is necessary to always select the air conditioning mode with the operation control means set to "operation". As mentioned above, if the air conditioning capacity of the air conditioner is suppressed to the minimum by the selection mode, the air conditioning of the air conditioned space can be maintained with less energy consumption as a result, but for the user, Air conditioner is “operating”
They become aware that the current situation is uneconomical.

In addition, when the operation control of an air conditioner is controlled by such an operation control device, it is possible for the user to perform operations that are familiar to him on a daily basis, such as when he leaves the room even though he wishes to operate the air conditioner continuously. (operation, stop operation) causes the operation control means to be selected as "stop", and the desired continuous air conditioning may be interrupted.

Furthermore, if the operation is temporarily interrupted as described above, by the time the operation is restarted, the room temperature will rise if it is in the cooling mode or fall if it is in the heating mode. For example, it takes a very long time for the room temperature to warm up, which significantly impairs comfort and increases electricity costs.

The present invention has been invented in this respect, and if the user selects the continuous air conditioning mode according to his/her wishes, from this selection onwards, the previous intermittent air conditioning mode will be changed.
