  However, in the conventional configuration, when the emergency operation is started when an abnormality occurs in the indoor temperature sensor, the operation is performed in a state where the indoor temperature cannot be adjusted at all. For this reason, during the cooling operation, the room temperature may drop before the user feels uncomfortable.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide an air conditioning system in which user discomfort is reduced in emergency operation when an abnormality occurs in a room temperature sensor.

  In order to solve the above-described conventional problems, an air conditioning system according to the present invention includes an indoor temperature sensor, an indoor temperature detection means, an indoor temperature sensor abnormality detection means, an indoor adoption temperature determination means, a control unit, and a communication means. An air conditioner system comprising an air conditioner and an outdoor unit having an outdoor temperature sensor and an outdoor temperature detecting means, and when the indoor temperature sensor abnormality detecting means detects an abnormality of the indoor temperature sensor, the indoor adopted temperature determining means is The indoor adopted temperature is varied according to the outdoor temperature detected by the outdoor temperature detecting means.

  As a result, it is possible to perform an emergency operation according to the user's temperature setting request, and to reduce the user's discomfort during the emergency operation.

  The air conditioning system of the present invention can reduce user discomfort during emergency operation when an abnormality occurs in the indoor temperature sensor.

  The first invention includes an air conditioner including an indoor temperature sensor, an indoor temperature detection means, an indoor temperature sensor abnormality detection means, an indoor adoption temperature determination means, a control unit, and a communication means, an outdoor temperature sensor, and an outdoor temperature detection means. An air conditioning system having an outdoor unit equipped with an outdoor unit in which the indoor adopted temperature determining means detects the indoor adopted temperature when the indoor temperature sensor abnormality detecting means detects an abnormality of the indoor temperature sensor. This is variable according to the temperature. By making this configuration, it is possible to perform an emergency operation according to the user's temperature setting request, and to reduce the user's discomfort during the emergency operation.

  The second invention is provided with an abnormality display determination means and an abnormality display section, and in particular, when the abnormality of the air conditioner of the first invention is detected, the abnormality display determination means displays the abnormality on the abnormality display section only during emergency operation Thus, with this configuration, it is possible not to notify the user of an abnormality that does not hinder the operation of the air conditioner, and to reduce the cost of repairing the air conditioner.

(Embodiment 1)
FIG. 1 shows a block diagram of an air conditioning system 1 according to a first embodiment of the present invention.

  In FIG. 1, an air conditioner 1 includes an indoor temperature sensor 6, an indoor temperature detection means 7, an indoor temperature sensor abnormality detection means 8, an indoor adoption temperature determination means 9, a control unit 10, and a communication means 11. 2 and an outdoor unit 3 having an outdoor temperature sensor 4 and an outdoor temperature detecting means 5. The operation and effect of the air conditioning system configured as described above will be described below.

  The outdoor temperature sensor 4 outputs a voltage (2.4 V as an example) according to a resistance value (as an example, 15 kΩ) according to the outdoor temperature.

  The outdoor temperature detecting means 5 detects the outdoor temperature (for example, 30 ° C.) from the voltage value output from the outdoor temperature sensor 4.

  The room temperature sensor 6 outputs a voltage value (2.4 V as an example) corresponding to a resistance value (15 kΩ as an example) according to the room temperature.

  The room temperature detecting means 7 detects the room temperature (for example, 25 ° C.) from the voltage value output from the room temperature sensor 6.

  The room temperature sensor abnormality detection means 8 detects whether or not the room temperature detected by the room temperature detection means 7 is an abnormal value (sensor open, sensor short, etc.).

  The indoor adoption temperature determination means 9 determines the indoor temperature adopted in the operation control of the air conditioner.

  The control unit 10 controls the operation of the air conditioner 2 based on the room temperature and the temperature setting determined by the indoor adoption temperature determining means 9 (for example, 28 ° C. during cooling operation).

  The communication unit 11 transmits and receives various control signals (operation ON, operation OFF, etc.) to and from the outdoor unit 3.

  In the air conditioning system 1 configured as described above, when the indoor temperature sensor abnormality detecting means 8 detects an abnormality of the indoor temperature sensor 6, the indoor adopted temperature determining means 9 detects the indoor adopted temperature by the outdoor temperature detecting means 5. The temperature is varied according to the outdoor temperature (for example, the cooling set temperature is lowered by 1 ° C. when the outdoor temperature is 30 ° C. or higher, and the heating set temperature is raised by 1 ° C. when the outdoor temperature is 10 ° C. or lower).

  Therefore, it is possible to perform an emergency operation according to the user's temperature setting request, and to reduce the user's discomfort during the emergency operation.

(Embodiment 2)
FIG. 2 is a block diagram of the air conditioning system 1 according to Embodiment 2 of the present invention. In FIG. 2, the same reference numerals are used for the portions described in the first embodiment, and description thereof is omitted.

  The abnormality display determination means 12 determines whether or not to display an abnormality when the indoor temperature sensor abnormality detection means 8 detects an abnormality of the indoor temperature sensor 6.

  The abnormality display unit 13 displays an abnormality of the air conditioner 2 (LED blinking, abnormality symbol H20 display, etc.).

  In the air conditioning system 1 configured as described above, when the air conditioner 2 is abnormal, the abnormality display determination unit 12 displays the abnormality on the abnormality display unit 13 only during emergency operation.

  Therefore, it is not possible to notify the user of an abnormality that does not hinder the operation of the air conditioning system, and the repair service cost of the air conditioning system can be reduced. In addition, since the abnormality display is not performed during the emergency operation, the user's anxiety can be reduced.

  As described above, the air conditioning system of the present invention can reduce the user's discomfort during emergency operation when an abnormality occurs in the indoor temperature sensor, and thus detects the physical quantity necessary for operation control of the air conditioning system. It can also be applied to applications such as emergency operation when functional abnormalities occur in various sensors.
