All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1 shows a flow chart of a control method of an air duct machine provided by the invention. As shown in fig. 1, the method includes:

s110, receiving the zone temperature and the zone humidity transmitted by the air box in the zone to be regulated;

And S120, controlling the operation frequency of the compressor and/or air valves corresponding to a plurality of areas to be regulated based on the area temperature and the area humidity.

It should be noted that, the air duct machine is connected to a plurality of air doors (air outlets) through air ducts, the plurality of air doors are in one-to-one correspondence with a plurality of areas to be adjusted, and each area to be adjusted is provided with an air box.

The air box is intelligent hardware for healthy air management, is an intelligent control terminal integrating multiple functions of intelligent control, air detection and the like, can accurately monitor temperature, humidity and air quality information in the environment in real time, and can also sense historical monitoring data of the indoor environment for a user body.

It should be further noted that, the air boxes corresponding to the multiple areas to be adjusted are all in communication connection with the area controller in the air duct machine, and the communication connection can be realized specifically through a communication response mechanism or a mode of setting address mutual recognition.

It is easy to understand that in step S110, the area temperatures and the area humidities of the plurality of areas to be adjusted are respectively obtained through the air boxes disposed in the plurality of areas to be adjusted, and the obtained area temperatures and the obtained area humidities are transmitted to the area controller based on the communication connection with the area controller of the air duct machine, and the area controller is used for integrating and analyzing the data transmitted by each area to be adjusted.

The system defaults that a plurality of areas to be regulated have environment regulation requirements, and air valves corresponding to the areas to be regulated are opened by default. Of course, the adjustment may be performed according to the actual opening or closing condition of the air valve corresponding to the area to be adjusted, which is not limited herein.

It should be noted that, the air box may collect the area temperature and the area humidity of the area to be adjusted in real time, or may collect the area temperature and the area humidity of the area to be adjusted according to a set period of time, which is not limited herein.

In step S120, after receiving the zone temperatures and the zone humidities of the respective zones to be adjusted, the zone controller controls at least one of the compressor operating frequency and the dampers corresponding to the zones to be adjusted according to the received zone temperatures and zone humidities, so that the temperatures and humidities of the respective zones to be adjusted reach the user requirements.

That is, in the case where the zone temperature and the zone humidity are obtained, only the compressor operation frequency may be adjusted according to the zone temperature and the zone humidity, only the dampers corresponding to the plurality of zones to be adjusted may be adjusted according to the zone temperature and the zone humidity, and also the compressor operation frequency and the dampers corresponding to the plurality of zones to be adjusted may be adjusted simultaneously according to the zone temperature and the zone humidity.

In addition to controlling the compressor operating frequency and the damper, other operating parameters of the ducted air machine, such as the fan rotational speed and the damper opening angle, may be adjusted, which are not particularly limited herein.

In addition, taking an example that the air duct machine corresponds to 3 areas to be adjusted, fig. 2 shows a control schematic diagram of the control method of the air duct machine provided by the invention.

As shown in fig. 2, the outdoor unit is connected to an indoor unit, and the indoor unit is provided with a zone controller that integrates and analyzes zone temperatures and zone humidities of the zones to be regulated 1,2, and 3. The zone temperature and the zone humidity are acquired by an air box arranged in each zone to be regulated.

In this embodiment, the operating frequency of the compressor and/or the air valves corresponding to the plurality of regions to be adjusted are controlled based on the region temperature and the region humidity by receiving the region temperature and the region humidity transmitted by the air box in the region to be adjusted, so that the ambient temperature and the humidity of each region to be adjusted respectively reach the set temperature and the set humidity. According to the method, the air boxes arranged in the multiple areas to be regulated are used for collecting the accurate temperatures and the humidity of the multiple areas to be regulated, so that the operation frequency of the compressor and the air valve are controlled according to the collected temperatures and the collected humidity of the multiple areas to be regulated, the aim of accurately regulating the temperatures and the humidity of the multiple areas to be regulated is fulfilled, the defect that the conventional air pipe machine cannot accurately control the temperatures of the multiple areas and does not control the humidity is overcome, the accurate control of the temperatures and the humidity of the multiple areas is realized, and the user experience is effectively improved.

On the basis of the above embodiment, further, based on the zone temperature and the zone humidity, the operation frequency of the compressor and/or the air valves corresponding to the plurality of zones to be adjusted are controlled, and the operation frequency adjustment process of the compressor and the control process of the air valves corresponding to the zones to be adjusted are described below, respectively.

In a specific embodiment, the step of controlling the air valves corresponding to the multiple areas to be regulated includes the steps of obtaining target area temperatures and target area humidities corresponding to the multiple areas to be regulated, calculating an area temperature difference value between the area temperature of each area to be regulated and the target area temperature, calculating an area humidity difference value between the area humidities of each area to be regulated and the target area humidities, and regulating the valve opening of the air valve corresponding to each area to be regulated according to the area temperature difference value and the area humidity difference value.

It should be noted that, one air duct machine corresponds to a plurality of areas to be adjusted, different areas to be adjusted have different areas, and corresponding to different environmental adjustment requirements, the environmental adjustment requirements may specifically be a target area temperature and a target area humidity corresponding to each area to be adjusted, and the target area temperature and the target area humidity may be set according to the area and specific conditions, which are not limited specifically herein.

For example, in one embodiment, the current zone temperature of zone 1 to be conditioned is 28 degrees celsius, the target zone temperature is 26 degrees celsius, the current zone humidity is 65%, and the target zone humidity is 50%.

For another example, in another embodiment, the current zone temperature of the zone 2 to be conditioned is 28 degrees celsius, the target zone temperature is 24 degrees celsius, the current zone humidity is 55%, and the target zone humidity is 50%.

For another example, in yet another embodiment, the current zone temperature of the zone 3 to be conditioned is 28 degrees celsius, the target zone temperature is 20 degrees celsius, the current zone humidity is 60%, and the target zone humidity is 50%.

It can be understood that the operation frequency of the compressor is controlled, specifically, the target area temperature and the target area humidity corresponding to the plurality of areas to be adjusted are obtained first, and the difference between the area temperature and the target area temperature of each area to be adjusted, that is, the area temperature difference, can be calculated at this time, and meanwhile, the difference between the area humidity and the target area humidity of each area to be adjusted, that is, the area humidity difference, can be calculated.

Furthermore, the valve opening of the air valve corresponding to each area to be regulated can be regulated according to the calculated area temperature difference value and the area humidity difference value. In general, the larger the region temperature difference, the larger the valve opening degree of the corresponding damper, and conversely, the smaller the valve opening degree of the corresponding damper.

For the regional humidity, under the condition that the difference between the regional humidity and the target regional humidity is relatively large, the indoor humidifying equipment can be combined, so that the regional humidity reaches the target regional humidity as soon as possible.

In another specific embodiment, the step of controlling the compressor operating frequency includes determining a maximum zone temperature difference value of a plurality of zone temperature difference values corresponding to a plurality of zones to be regulated, determining a maximum zone humidity difference value of a plurality of zone humidity difference values corresponding to a plurality of zones to be regulated, and controlling the compressor operating frequency according to the maximum zone temperature difference value and the maximum zone humidity difference value.

It can be understood that the compressor operating frequency is controlled, specifically, based on the above-mentioned region temperature difference value and the region humidity difference value corresponding to each region to be adjusted, the maximum region temperature difference value in the region temperature difference values and the maximum region humidity difference value in the region humidity difference values can be determined based on the region temperature difference values and the region humidity difference values corresponding to the region to be adjusted.

Further, according to the determined maximum area temperature difference value and the determined maximum area humidity difference value, the operation frequency of the compressor is controlled, and the compressor is expanded to operate according to the operation frequency of the compressor corresponding to the maximum area temperature difference value and the maximum area humidity difference value, so that the temperature requirements and the humidity requirements of other areas to be regulated except the areas to be regulated corresponding to the maximum area temperature difference value and the maximum area humidity difference value can be met.

Generally, the greater the zone temperature difference, the higher the compressor operating frequency and vice versa. The greater the zone humidity difference, the higher the compressor operating frequency and, conversely, the lower the compressor operating frequency.

In this embodiment, by acquiring the target area temperatures and the target area humidities corresponding to the plurality of areas to be adjusted, calculating an area temperature difference between the area temperature and the target area temperature of each area to be adjusted and an area humidity difference between the area humidities and the target area humidities of each area to be adjusted, determining a maximum area temperature difference among the plurality of area temperature differences and a maximum area humidity difference among the plurality of area humidity differences, adjusting the valve opening of the air valve corresponding to each area to be adjusted according to the area temperature differences and the area humidity differences, and controlling the operation frequency of the compressor according to the maximum area temperature differences and the maximum area humidity differences. According to the method, the operating frequency of the compressor and the air valve are controlled according to the region temperature and the region humidity collected by the air box, so that the aim of accurately adjusting the region temperatures and the humidity to be adjusted is fulfilled, the defect that the conventional air duct machine cannot accurately control the region temperatures and does not control the humidity is overcome, the accurate control of the region temperatures and the humidity is realized, and the user experience is effectively improved.

On the basis of the embodiment, further, the control of the compressor operating frequency and/or the air valves corresponding to the multiple areas to be regulated is carried out, and then the control comprises the steps of determining that the area temperatures of the multiple areas to be regulated reach the target area temperature and the area humidity of the multiple areas to be regulated reach the target area humidity, controlling the compressor operating frequency to the set compressor operating frequency, and controlling the valve opening of the air valves corresponding to the areas to be regulated to the minimum valve opening.

It is easy to understand that after the operation frequency of the compressor and/or the air valves corresponding to the multiple areas to be regulated are controlled, the area temperature and the area humidity of each area to be regulated are continuously monitored in real time, and when it is determined that the area temperature of the multiple areas to be regulated reaches the target area temperature and the area humidity of the multiple areas to be regulated reaches the target area humidity, the environment requirement of each area to be regulated is indicated to be reached, at this time, the compressor is not required to operate at a high operation frequency, the valve opening of the air valve is not required to be particularly large, and in order to avoid resource waste, the operation frequency of the compressor is controlled to be equal to the set operation frequency of the compressor, and at the same time, the valve opening of the air valve corresponding to the area to be regulated is controlled to be equal to the minimum valve opening.

The set compressor operating frequency may be set according to actual conditions, and is not particularly limited herein. For example, in one particular embodiment, the compressor operating frequency is set to a minimum compressor operating frequency.

In this embodiment, when it is determined that the region temperatures of the plurality of regions to be adjusted reach the target region temperature and the region humidity of the plurality of regions to be adjusted reach the target region humidity, the operating frequency of the compressor is controlled to the set operating frequency of the compressor, and the valve opening of the corresponding air valve of the region to be adjusted is controlled to the minimum valve opening, so that unnecessary resource waste is avoided.

On the basis of the above embodiment, it is further determined that the area temperatures of the plurality of areas to be adjusted reach the target area temperature, and the area humidity of the plurality of areas to be adjusted reach the target area humidity, specifically, the method includes two cases, that is, the area humidity of the area to be adjusted of the opened air valve reaches the target area humidity first, and then reaches the target area temperature after the corresponding area temperature, but the area temperature of the area to be adjusted of the opened air valve reaches the target area temperature first, and then reaches the target area humidity after the corresponding area humidity.

In a specific embodiment, determining that the area temperature of a certain area to be regulated of the opened air valve reaches the target area temperature after a first time period, determining that the area humidity of the area to be regulated reaches the target area humidity after a second time period, wherein the first time period is longer than the second time period, that is, the time required for the area temperature of the area to be regulated to reach the target area temperature is longer.

At the moment, the corresponding air valves are controlled to be continuously opened, the air box is opened to humidify the air box until the region temperature of the region to be regulated reaches the target region temperature, and the region humidity of the region to be regulated reaches the target region humidity.

In another embodiment, the temperature of the area to be regulated is determined to reach the target area temperature after a first time period, the humidity of the area to be regulated is determined to reach the target area humidity after a second time period, and the first time period is smaller than the second time period, namely, the time required for the humidity of the area to be regulated of the opened air valve to reach the target area humidity is longer.

At the moment, the corresponding air valve is controlled to be closed for m minutes, and the air valve is controlled to be opened for n minutes until the area temperature of the area to be regulated reaches the target area temperature and the area humidity of the area to be regulated reaches the target area humidity.

Wherein m and n are positive integers. The specific values of m and n can be intelligently and dynamically adjusted according to the adjusting effect, and m and n can be the same value or different values, and are not particularly limited.

It should be noted that, the first duration and the second duration in the above two embodiments may be set according to specific situations, which is not limited herein.

In this embodiment, by comparing the time period when the region temperature of the region to be adjusted reaches the target region temperature with the time period when the region humidity of the region to be adjusted reaches the target region humidity, different treatments are performed on the corresponding air valves according to different comparison results, so as to achieve the purpose of accurately adjusting the temperature and humidity of a plurality of regions to be adjusted, overcome the defect that the existing air duct machine cannot accurately control the temperature of a plurality of regions and does not perform humidity control, realize the accurate control of the temperature and humidity of a plurality of regions, and effectively promote the user experience.

It is understood that when adjusting the zone temperature of the zones to be adjusted, a control time for the zone temperature of each zone to be adjusted to reach the target zone temperature may be obtained, where the control time is started at a time point when the zone temperature of the air box transmission is received, and is stopped at a time when the zone temperature reaches the target zone temperature.

On the basis of obtaining control time corresponding to a plurality of areas to be regulated, the longest control time in the control time and the area to be regulated corresponding to the longest control time can be determined, the air door corresponding to the area to be regulated can be further determined, the air door corresponding to the area to be regulated in the longest control time is set to be a normally open air door, the normally open air door is opened when the air pipe machine starts to operate, and the air pipe machine continuously operates without stopping to operate and is not closed, so that the control time for the area temperature of the area to be regulated to reach the target area temperature can be effectively reduced when the area temperature of the area to be regulated is regulated next time.

It should be noted that, in this embodiment, the normally open damper may be set according to the maximum time for the zone humidity to reach the target zone humidity, which is not specifically developed herein.

In the embodiment, the control time for the region temperature of the plurality of regions to be regulated to reach the target region temperature is determined, the region to be regulated corresponding to the longest control time in the plurality of control times is determined, and the air door corresponding to the region to be regulated in the longest control time is set as the normally open air door, so that the control time for the region temperature of the region to be regulated to reach the target region temperature is effectively reduced, and the experience of a user is improved.

The preset target user may be set according to actual situations or requirements, which is not limited herein. For example, the preset target user can be a crowd with special requirements, such as old people and children, and can also be a crowd with important requirements.

It should be noted that, the temperature, humidity and air quality wanted by the preset target user are stored in the system database in advance, and can be directly called.

If the facial information of the user cannot be matched with the preset identity information in the system database, no further operation is performed.

In this embodiment, the identity information of the user is identified, the user is determined to be a preset target user, and the region temperature, the region humidity and the region air quality of the region to be adjusted are adjusted according to the position information of the preset target user. The method can carry out self-defined adjustment on the temperature, the humidity and the air quality of the area to be adjusted according to the specific requirements of a single user, and further improves the experience of the user.

Based on the historical temperature adjustment progress obtained by analysis, the real-time temperature adjustment progress can be guided. For example, the temperature of the area to be regulated can be regulated from the first temperature to the second temperature within a second time, and the second time is smaller than the first time, and at this time, the opening of the damper can be increased on the basis of the opening of the damper in the history regulation information so as to satisfy the foregoing requirement.

It should be noted that the content of this embodiment is also applicable to humidity control, and is not specifically developed here.
