[0030] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] figure 1 Shows the structural block diagram of the regional control part of the air conditioner of the present invention, a set of air conditioning units of the present invention corresponds to n blocks of areas, each area is provided with a damper and a temperature controller, and each damper corresponds to a damper After the controller, the zone controller processes the temperature fed back by the thermostat, it sends a control command to the damper controller, and then the damper controller adjusts the switch and/or opening of the damper according to the control command.
[0032] figure 2 It shows the detailed flow chart of the regional control method of the present invention. When the air conditioning function is turned on in some or all regions, that is, the cooling function, heating function or air supply function is turned on, the regional controller detects the temperature of the region according to the temperature controller. temperature to calculate the temperature change rate per unit time of the area where the air-conditioning function is turned on. If the temperature change rate of only one area is calculated in a unit time, it means that only one area currently has the air-conditioning function turned on. At this time, according to the The percentage of the air volume of the zone controls the speed of the fan of the air conditioner. If the air conditioning function is turned on in multiple areas within a unit time, it is necessary to judge whether the latest temperature change rate of the area (that is, the temperature change rate calculated last time in each area in chronological order) is too large or too small, and the temperature change rate Reduce the air volume of the larger area by a certain percentage, and increase the air volume of the area with a smaller temperature change rate by the same percentage, that is, the sum of the percentages of the areas with the air-conditioning function remains unchanged to ensure that all areas have the air-conditioning function The sum of the percentages of the air volume at the time is kept at 100% from the beginning to the end, and then the sum of the percentages of the areas where the air-conditioning function is currently turned on is calculated. The area controller controls the fan speed of the air-conditioning according to the percentage sum of the areas where the air-conditioning function is currently turned on. Specifically, you can The speed of the fan of the air conditioner is controlled according to the percentage sum through the preset relationship table between the percentage sum and the fan speed.
[0033] In one embodiment of the present invention, the sum of the air volume percentages in all areas is divided into 6 grades, and the fan speed of the air conditioner corresponding to each grade is set. When the air volume percentage exceeds 80%, the fan speed can be controlled to the highest. Speed, or other speeds with relatively strong wind, as shown in the table below:
[0034]
[0035] Specifically how to judge whether the latest temperature change rate of a certain area among multiple areas is too large or too small, the present invention first sorts all the areas with the air-conditioning function turned on from 1-n according to the temperature change rate of the area, Then judge whether there is a remainder when n is divided by 2.
[0036] If there is a remainder, the temperature change rate of the area with the serial number ⌊n/2⌋+1 is taken as the standard value, the area with the temperature change rate greater than the standard value is regarded as the area with a relatively large temperature change rate, and the temperature change rate is smaller than the standard value The area is regarded as the area where the rate of temperature change is relatively small. For example, the temperature change rate is arranged according to the value from small to large, and there are 3 areas in total (n=3), then the temperature change rate of the area with the serial number ⌊3/2⌋+1=2 is used as the standard value, then The area with serial number 1 is the area with relatively small temperature change rate, and the area with serial number 3 is the area with relatively large temperature change rate. The percentage of specific regulation can be set by those skilled in the art according to needs, for example, the air volume of the area numbered 1 is increased by 1%, and the air volume of the area numbered 3 is decreased by 1% at the same time, so as to control the balance of the sum of the air volume percentages.
[0037] If there is no remainder, the area is divided into two areas with serial numbers greater than n/2 and serial numbers less than or equal to n/2, and then according to the temperature change rate, one of the two areas is determined to be the area with a relatively large temperature change rate. The other part is the area where the temperature change rate is relatively small. For example, the temperature change rate is arranged according to the value from small to large, and there are 4 areas in total (n=4), then the area is divided into a part with a serial number greater than n/2=2 and a part with a serial number less than or equal to 2, that is, the serial number is The areas of 3 and 4 belong to one part, and the areas with serial numbers 1 and 2 belong to one part. Since the temperature change rate is arranged according to the value from small to large, the areas with serial numbers 1 and 2 are areas with relatively small temperature change rates. The areas of 3 and 4 are the areas where the temperature change rate is relatively large.
[0038]The implementation process of the present invention will be described below with a specific example. Suppose a 100-square-meter house is divided into 4 rooms (that is, 4 areas), the area of room R1 is 20 square meters, the area of room R2 is 30 square meters, the area of room R3 is 10 square meters, and the area of room R4 is 40 square meters, then the air volume of these four rooms should be set to 20%, 30%, 10%, and 40% if they are divided according to the area. First read the temperature change Cn of the air-conditioned room within a unit time. If only room R1 is currently in cooling mode or heating mode, then the air volume B1 of room R1 is fixed at 20%, and the fan speed is determined by the relationship table above. It is concluded that the sum of the air volume percentages is in the range of 17%-32%, so the speed D level of the fan should be controlled at level 2. If the current room R1 and room R2 are running in cooling mode or heating mode at the same time, then first sort the temperature changes of the air-conditioned rooms. And take the variation of the room in the middle of the sorting as the standard reference value, consider the room with the variation greater than the standard value as the temperature change too fast, the air volume of this type of room is reduced by 1%, and the room with the variation smaller than the standard value is regarded as the temperature change In the slow case, the air volume of this type of room is increased by 1%, so that the air volume can be adjusted in real time, dynamically adapting to various factors, and the sum of the air volume of all rooms is 100% from the beginning to the end. Since there are currently only two rooms, there is no need to compare with the standard value. The air volume of the room with a large temperature change rate is reduced by 1%, and the air volume of the room with a small temperature change rate is increased by 1%. For example, the temperature change rate C1 of room R1 per unit time is 1%, and the temperature change rate C2 of room R2 per unit time is 0.5%, then the air volume B1 of room R1 decreases from 20% to 19%, and the air volume B2 of room R2 increases from 30%. was 31%. The air conditioner will make such adjustments in each unit of time. Each adjustment is based on the air volume percentage after the previous adjustment. As time progresses, the air volume settings of all rooms will be changed from the original 20%, 30%, and 10%. , 40%, may be adjusted to 25%, 20%, 20%, 35%, we can record and learn this adjusted percentage, and directly use this percentage when the next boot. When room R1 and room R2 are running at the same time, the total air volume is 25%+20%=45%, and the speed D of the fan is controlled at level 3 wind speed, while the fan speed before adjustment is controlled at level 4 wind speed. By analogy, the air conditioner can dynamically adjust the air volume and fan speed.
[0039] After adjusting the air volume percentage of each area (room), the optimal adjustment state can be achieved through the controllable air valve. like image 3 As shown, the air valve opening A is gradually reduced in the room where the temperature changes too fast, and the air valve opening A is gradually increased in the room where the temperature changes slowly. In order to adapt to various dynamically changing environmental factors and improve user experience. Of course, the present invention is not limited to the type of air valve, that is, it is not limited to the use of air valves with controllable openings, such as Figure 4 As shown, if a traditional air valve that can only be controlled to switch is used, the air valve controller controls the air valve switch by comparing the temperature detected by the thermostat with the temperature set by the user. Assuming that the current cooling function is on, when the temperature of the thermostat is When the temperature is higher than the set temperature, the air valve is opened, otherwise it is closed. When the heating function is turned on, when the temperature of the thermostat is lower than the set temperature, the air valve will be opened, otherwise it will be closed. This will not affect the dynamic adjustment of the air volume, and reduces the cost compared with the damper that controls the opening.
[0040] The unit time of the present invention can be continuous or interval. For example, if the duration of the unit time is set to 1 hour, then the temperature change rate of the previous hour can be calculated every hour, or there can be a certain time interval between two adjacent unit times, for example, a unit After 1 hour of time has passed, after an interval of 40 minutes, the next 1 hour will be counted.
[0041] Through the above self-adjustment method, the zone controller intelligently adjusts the percentage of air volume in each zone (room), realizes real-time control of fan wind speed, and each zone realizes independent control of air valve opening, so that the air volume of each room can be balanced.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
