Abstract

PURPOSE:To ensure excellent comfortability in a room, corresponding to an abnormal system, by a method wherein a room temperature signal value from the room temperature sensor of a detection and transmission system under an abnormal state is replaced with a room temperature signal value from the room temperature sensor of other normal detection and transmission system. CONSTITUTION:When a trouble occurs in a detecting and transmission system 22 for a first room temperature signal, an abnormal first room temperature signal value TA is replaced with a normal room temperature signal value TB through the working of a second control part 21 of a control circuit 15. This replacement causes a total volume of compressors 1 and 2 to be varied and controlled by a full deviation (TB-TA) between the first room temperature signal value TA and the second room temperature signal value TB by a first control part 20. However, since the deviation (TB-TA) between the two room temperature values TA and TB is originally reduced to a low value by air condi tioning operation, the interior of a room corresponding to the first detection and transmission system 22, to which abnormality occurs, is excellently air- conditioned, and indoor comfortability is ensured excellently as much as possible.

Now, in this state, for example, the first room temperature sensor (TI-IA
) is broken or its transmission wiring (17) is 1tfi.
If an abnormality occurs in the first room temperature signal detection and transmission system 22), such as when printing occurs, the second control section (21) of the control circuit (15) detects the abnormal first room temperature signal. 1+a
TA is replaced with the normal second room temperature signal value Ts, and as a result, the total capacity of the compressors (1) and (2) is determined by the first controller (20) to be equal to the first room temperature signal 1+n TA and the second room temperature signal value Ts.
Although the room temperature is controlled to increase or decrease by 1q difference (TB - TA) from the room thirst signal value TB, the deviation between these two room temperatures 1f (ITA, Ts (Ts - TA) is originally a small value due to air conditioning operation, so it is abnormal. The first detection and transmission system (2
The interior corresponding to 2) is still well air-conditioned, and indoor comfort is ensured as well as possible. Above, we have explained the case where the first room temperature signal is detected and the transmission system (22) is abnormal, but the same operation as above is performed also when the second detection and transmission system (23) is abnormal. Good quality is ensured.

In addition, with this configuration that converts the abnormal room temperature signal 11a to the normal room temperature signal value by 1N, it is possible to, for example, connect multiple rooms at once with one representative palm humidity signal from one room temperature sensor (for example, T11A). If there is a request to control the temperature, simply remove the other room temperature sensor (TI-18) and the eI! 11. Therefore, in this case, there is no need to make initial IXI settings for individual control or batch control, depending on the model of the air conditioner.

(Effects of the Invention) As explained above, according to the present invention, in a multi-type air conditioner, if an abnormality occurs in any of the indoor temperature signal detection and transmission systems, for,
The room temperature signal value belonging to this abnormal system is directly replaced by the detection of other normal room temperature signals and the room temperature signal of the transmission system (directly replaced with the indoor air conditioning operation corresponding to the abnormal system, so that when this abnormal system occurs, In addition, it is possible to satisfactorily ensure the comfort in a corresponding room.Furthermore, it becomes easy to deal with cases where multiple rooms are represented by one room temperature sensor and air-conditioned all at once.
