Description
Technical Field
The invention relates to the technical field of air-conditioning indoor temperature control, in particular to an air-conditioning indoor temperature control method and system.
Background
An air conditioner is an electric appliance mainly used for adjusting indoor temperature to provide a comfortable environment, and the quality of a temperature control function of the air conditioner is closely related to the comfort experience of a user in the using process.
At present, an indoor temperature regulation mode of an air conditioner is generally that an indoor greenhouse sensor is arranged on an indoor unit of the air conditioner, is mostly arranged at an air return position of the air conditioner and is used for detecting the indoor air temperature, a user manually sets an operation mode of the air conditioner and an indoor control target temperature by using a remote controller, and the operation state of the air conditioner is controlled by simply comparing a temperature measurement value with a set target temperature value; for example, in summer, under the refrigeration working condition, if the temperature measurement value is smaller than the target temperature value, the compressor is stopped not to refrigerate, and if the temperature measurement value is not smaller than the target temperature value, the refrigeration operation is carried out; in contrast, in winter, heating is stopped in the heating condition if the temperature measurement value is greater than the target temperature value. Most of the air conditioner temperature measurement adopts a resistance type temperature sensor with low cost.
In the use process of the variable frequency air conditioner, a user can often feel the condition of cold and hot. In the environment changes of the body, the body feeling comfort level is not felt, and the body health of the user is seriously influenced. Especially, the old, children and weak and sick people at home are easy to catch a cold or other uncomfortable symptoms.
Firstly, the existing variable frequency air conditioner cannot accurately adjust and control the room temperature on the conventional control principle, so that excessive electric energy consumption is generated, unnecessary resource waste is caused, and the original purpose of energy saving of the variable frequency air conditioner is violated; secondly, the inaccurate temperature adjustment and unstable temperature control of the variable frequency air conditioner can cause the outdoor unit to be in a high-speed running state for a long time, and the service life of the air conditioner is greatly reduced.
The overshoot is the process that the inverter air conditioner regulates and controls the indoor temperature, and the actual control temperature of the system and the target set temperature generate a positive deviation of about 3 degrees at most due to the poor accuracy of the temperature control technology of the common inverter air conditioner. This is also the reason why most of the variable frequency air-conditioning rooms only display the set temperature and do not display the actual room temperature. The temperature control curve is like that a drunk driver drives around a large S on a highway, so that the system is ineffective and waste, and is power-consuming and uncomfortable.
Experts point out that the sampling resolution of a temperature control sensor of a variable frequency air conditioner in the industry at present is generally 1 ℃, and the cooling speed of the air conditioner in a room is generally 0.2 ℃/min, so that the actual cooling effect can be obtained by the variable frequency air conditioner within 5-10 minutes. And (3) making an image metaphor: if two vehicles running in the same direction want to catch up with the front vehicle and keep parallel, the distance and the relative speed of the two vehicles must be known, and if the relative speed is not known, the situation that the rear vehicle exceeds the front vehicle is easy to occur. In the control of the variable frequency air conditioner, only the difference (distance) between the set temperature and the actual room temperature is known, but the cooling speed (relative speed) is not known or cannot be obtained in time, so that the control temperature exceeds the set temperature, and the control overshoot occurs.
On 29 months 1 in 2019, the bluetooth alliance has formally promulgated the bluetooth 5.1 standard and has been opened to developers. The greatest change in the new standard is that the accuracy of position tracking is improved to the centimeter level, so as to replace the role of WiFi auxiliary positioning, in other words, the Bluetooth 5.1 can realize centimeter level positioning without WiFi assistance. The former Bluetooth 5.0 can realize the Bluetooth indoor positioning function with the precision close to 1 meter by matching with Wi-Fi. However, the new standards still require some time to be truly widely applied to consumer grade products.
The inventor of the present invention has seen a prospective finding that the emergence of the bluetooth 5.1 standard makes it possible for an air conditioner to precisely control the temperature.
