The invention relates to a control method, system and device for a failed environment temperature sensor of an indoor unit of an air conditioner. The method comprises the steps: when the detection temperature of an indoor unit environment temperature sensor cannot be obtained, determining a control temperature difference based on a logic relation between the detection temperature of a coil pipe sensor of the indoor unit and the detection temperature of an environment temperature sensor of the indoor unit and parameter values involved in the logic relation; and according to the control temperature difference, executing the control logic of operation of the air conditioner. Therefore, as the coil pipe sensor of the indoor unit is introduced, alternative control of the environment temperature sensor of the outdoor unit on the environment temperature sensor of the indoor unit is realized by utilizing a checking calculation logic relation of the temperature of the environment temperature sensor of the indoor unit; and low user experience and high cost of maintenance, personnel and the like caused by the fact that the air conditioner alarms or stops and does not operate when the indoor environment temperature sensor fails are avoided.
Description
technical field [0001] This manual belongs to the technical field of air conditioner operation control, and in particular relates to a control method, system and device after an indoor unit ambient temperature sensor fails. Background technique [0002] The indoor unit of the air conditioner is usually equipped with an indoor ambient temperature sensor to detect the indoor temperature. In the cooling mode, when the indoor ambient temperature is higher than the set temperature of the air conditioner, the air conditioner is turned on / running; when it is not higher than the set temperature of the air conditioner, The air conditioner will stop; in heating mode, when the indoor ambient temperature is lower than the set temperature of the air conditioner, the air conditioner will start / operate, and when it is not lower than the set temperature of the air conditioner, the air conditioner will stop; if the ambient temperature sensor of the indoor unit is the indoor unit The ambient ...
