Indoor unit of air conditioner, control method, air conditioner and readable storage medium

Abstract

The invention provides an indoor unit of an air conditioner, a control method, the air conditioner and a readable storage medium. The indoor unit of the air conditioner comprises a heat exchanger, a first temperature sensor, a second temperature sensor, a third temperature sensor and a controller, wherein the first temperature sensor is used for collecting the input refrigerant temperature of theheat exchanger; the second temperature sensor is used for collecting the output refrigerant temperature of the heat exchanger; the third temperature sensor is used for collecting the environment temperature; the controller is connected with the first temperature sensor, the second temperature sensor and the third temperature sensor; the controller is used for determining the operation state of thefirst temperature sensor and the operation state of the second temperature sensor according to the environment temperature, the input refrigerant temperature and the output refrigerant temperature; and temperature control parameters are determined according to the operation states of the first temperature sensor and the second temperature sensor and the input refrigerant temperature and / or the output refrigerant temperature. According to the indoor unit of the air conditioner, the control method, the air conditioner and the readable storage medium, the fault states of the two temperature sensors are determined in time, so that the indoor unit can be controlled according to the accurate refrigerant temperature.

Description

technical field [0001] The invention belongs to the field of air conditioning control, and in particular relates to an indoor unit of an air conditioner, a control method for the indoor unit of the air conditioner, an air conditioner and a computer-readable storage medium. Background technique [0002] The temperature sensor of the air conditioner indoor unit is in the cooling state, and the sensor is always in a high-humidity and humid environment. The sensor in this environment is prone to temperature drift. The temperature detected by the sensor is different from the actual temperature. According to the temperature detected by the sensor, the external opportunity Misjudged the evaporation capacity of the internal unit. Contents of the invention [0003] The present invention aims to solve one of the technical problems existing in the prior art or related art. [0004] For this reason, a first aspect of the present invention provides an indoor unit of an air conditioner...
