The invention relates to a control method, system and device after the failure of an ambient temperature sensor of an air conditioner indoor unit. Wherein, the method includes: when the detected temperature of the indoor unit ambient temperature sensor cannot be obtained, based on the logical relationship between the detected temperature of the indoor unit coil sensor and the detected temperature of the indoor unit ambient temperature sensor, and the logical relationship involved in the logical relationship The parameter value of , determines the control temperature difference, and executes the control logic of the air conditioner operation according to the control temperature difference. Therefore, the indoor unit coil sensor is introduced, and the check calculation logic relationship of the indoor unit ambient temperature sensor temperature is used to realize the substitute control of the outdoor unit ambient temperature sensor to the indoor unit ambient temperature sensor, so as to avoid the air conditioner alarm when the indoor ambient temperature sensor fails. Or downtime without operation brings low user experience and higher maintenance, personnel and other costs.
Description
technical field [0001] The present specification 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 cooling mode, when the indoor ambient temperature is higher than the set temperature of the air conditioner, the air conditioner will be turned on / run, and when it is not higher than the set temperature of the air conditioner, the 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 / run, and when it is not lower than the set temperature of the air conditioner, the air conditioner will stop; if the indoor unit ambient temperature sensor is the indoor unit The...
