Problems solved by technology
At present, the room temperature control accuracy of the inverter air conditioner is mainly controlled by the operating frequency of the compressor. Due to the reliability considerations such as noise or pipeline stress, the lower limit of the operating frequency range of the air conditioner has to be raised or increased a lot. The continuous operation frequency shielding point is used to ensure the reliability of the operation. As a result, the air conditioner cannot operate stably after the room reaches the set temperature, and there will be large fluctuations in temperature shutdown or compressor operating frequency. Improve user comfort experience and increase energy consumption

The invention provides an accurate temperature controlling method and a device of an air conditioner and the air conditioner, and relates to the technical field of the air conditioner. The problems that after the temperature of the air conditioner reaches, the air conditioner cannot stably operate, the air conditioner stops when reaching the temperature or the operation frequency of a compressor continuously rises and falls are solved. The accurate temperature controlling method comprises the following steps: an air conditioner temperature set value and a first indoor environment temperature value are obtained, according to the air conditioner temperature set value and a first indoor environment temperature value, a first target temperature difference value is determined, and operation parameters of the air conditioner are obtained and comprise current operation frequency information of the compressor of the air conditioner or current temperature information of an inner pipe of a heat exchanger of the air conditioner; according to the first target temperature difference value and the operation parameters of the air conditioner, the operation frequency of the compressor and or a rotation speed of a indoor fan are adjusted. According to the accurate temperature control method, the temperature of the air conditioner is accurately controlled through the joint control mode of controlling the operation frequency of the compressor and controlling the rotating speed of the indoor fan, and stable operation of the air conditioner is maintained.
Description
technical field [0001] The present application relates to the technical field of air conditioners, in particular to an accurate temperature control method and device for an air conditioner and an air conditioner. Background technique [0002] With the improvement of people's living standards and the continuous pursuit of a higher quality of life, the demand for intelligent household appliances is also increasing. They are no longer satisfied with the cooling and heating functions of air conditioners, and begin to pursue higher comfort. At present, the room temperature control accuracy of the inverter air conditioner is mainly controlled by the operating frequency of the compressor. Due to the reliability considerations such as noise or pipeline stress, the lower limit of the operating frequency range of the air conditioner has to be raised or increased a lot. The continuous operation frequency shielding point is used to ensure the reliability of the operation. As a result, t...
