Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

As shown in fig. 1, an air conditioning system control method according to an embodiment of the present invention includes:

determining the sunlight irradiation indoor environment in the refrigeration mode of the air conditioner, and acquiring the irradiation temperature and the outdoor temperature;

and controlling the curtain to be closed under the condition that the difference value between the irradiation temperature and the outdoor temperature is greater than a preset difference value.

The air conditioning system comprises an air conditioner and a curtain, the air conditioner is in communication connection with the curtain, and the irradiation temperature is the temperature of a window irradiated by sunlight.

In summer, the outdoor sunlight intensity is higher in daytime, and the outdoor temperature is higher. When the air conditioner operates in a refrigeration mode in summer, on one hand, outdoor high-temperature air enters an indoor environment to increase the indoor temperature, on the other hand, sunlight irradiates the indoor environment, the indoor temperature is easily increased due to solar radiation heat, the load of the air conditioner is increased, the refrigeration rate of the air conditioner is reduced, and the long-time high-load operation and even overload operation of the air conditioner cause energy consumption increase and possibly influence the service life of the air conditioner.

In order to avoid the influence of sunlight on the indoor temperature, the air conditioning system control method of the embodiment of the invention firstly judges whether the sunlight irradiates the indoor environment in the refrigeration mode. And if the sunlight irradiates the indoor environment, judging the sunlight intensity. Specifically, the sunlight intensity is judged by acquiring the difference value between the irradiation temperature and the outdoor temperature, wherein the irradiation temperature is the temperature of the window irradiated by sunlight.

If the irradiation temperature is higher than the outdoor temperature and the difference between the irradiation temperature and the outdoor temperature is larger than the preset difference, the sunlight intensity is high, the indoor temperature is easy to rise, and the refrigerating speed of the air conditioner is reduced. If the difference between the irradiation temperature and the outdoor temperature is smaller than or equal to the preset difference, the sunlight intensity is low, the temperature change caused by the irradiation of the sunlight on the indoor environment is low, and the refrigerating effect of the air conditioner is not easily influenced. It is understood that the window and the outdoor unit of the air conditioner are provided with temperature sensing devices for sensing an irradiation temperature and an outdoor temperature, respectively.

Under the condition that the difference value between the irradiation temperature and the outdoor temperature is larger than the preset difference value, the curtain is controlled to be closed, the outdoor solar radiation heat is isolated, the air conditioner can be rapidly refrigerated, and the working efficiency of the air conditioner is improved.

In an alternative embodiment, the window is equipped with a light intensity sensor for acquiring the light intensity of the sun and determining whether the sunlight irradiates the indoor environment.

Specifically, the illumination brightness sensor is mounted on a frame of the curtain, and the illumination brightness sensor acquires illumination brightness when the sun irradiates on the window. Further, comparing the illumination brightness with a preset illumination brightness, and if the illumination brightness is greater than or equal to the preset illumination brightness, irradiating the indoor environment by sunlight; if the illumination brightness is smaller than the preset illumination brightness, the sunlight does not irradiate the indoor environment. The preset illumination brightness is the minimum illumination brightness of the indoor environment irradiated by sunlight.

As another alternative embodiment, it is also possible to judge whether sunlight irradiates the indoor environment by comparing the indoor illumination brightness and the outdoor illumination brightness.

For example, at least one illumination brightness sensor is respectively arranged on one side of the window frame close to the indoor environment and one side close to the outdoor environment, and is used for acquiring indoor illumination brightness and outdoor illumination brightness. Further, comparing the difference value between the indoor illumination brightness and the outdoor illumination brightness with a preset value, if the difference value of the illumination brightness is larger than the preset value, the sunlight does not irradiate the indoor environment; and if the illumination brightness difference value is less than or equal to the preset value, the sunlight irradiates the indoor environment. The preset value is the maximum difference value between the indoor illumination brightness and the outdoor illumination brightness when the sunlight just irradiates the indoor environment.

The control method of the air conditioning system provided by the embodiment of the invention determines the sunlight irradiation indoor environment in the refrigeration mode, obtains the difference value between the irradiation temperature and the outdoor temperature, and judges the influence of the sunlight intensity on the indoor temperature; the curtain is controlled to be closed under the condition that the difference value is greater than the preset difference value, so that the condition that the indoor temperature is increased due to the fact that sunlight irradiates the indoor environment is prevented, the refrigerating effect of the air conditioner is influenced, the refrigerating efficiency of the air conditioner is improved, and the indoor temperature can be reduced quickly.

As a specific example, as shown in fig. 2, after controlling to close the window covering, the method further includes:

obtaining indoor brightness;

and controlling to turn on the lighting equipment under the condition that the indoor brightness is lower than the preset brightness.

After the curtain is controlled to be closed, the brightness of the indoor environment can be influenced, and in order to avoid inconvenience to users, the lighting equipment is controlled to be started under the condition that the indoor brightness is lower than the preset brightness. The preset brightness is preset brightness, and if the indoor brightness is lower than the preset brightness, the indoor light is weak, and the environment is dim.

In some embodiments, the air conditioning system control method further includes:

and under the condition that the difference value between the irradiation temperature and the outdoor temperature is greater than the preset difference value, if the user side equipment sends a cancel instruction, the curtain is controlled to be opened, and the air conditioner is controlled to increase the power. The air conditioning system further comprises customer premise equipment, and the customer premise equipment is in communication connection with the air conditioner and the curtain.

When the air conditioner system control method is executed, if a user does not want to close the curtain and sends a cancel instruction through the user side equipment, the air conditioner system control method is stopped being executed, the curtain is controlled to be opened, the air conditioner is controlled to increase the power, the influence of sunlight on the indoor temperature is reduced, and the air conditioner is enabled to refrigerate rapidly. The user end equipment is a remote controller, an APP end, an intelligent household appliance and the like, and the application is not limited specifically.

Alternatively, the air conditioner is controlled to lower the cooling temperature in the case that the curtain is closed.

For example, when a user sets a target temperature of 25 ℃ through a customer premise equipment, a cooling temperature of an air conditioner is also 25 ℃, and when an indoor temperature reaches 25 ℃, a compressor of the air conditioner is suspended. And under the condition that the curtain is closed, the air conditioner is controlled to reduce the refrigerating temperature to 23 ℃, when the indoor temperature reaches 23 ℃, the compressor of the air conditioner stops running, the refrigerating speed of the air conditioner is increased, and the indoor temperature is favorably and quickly reduced.

In addition, if the driving device for driving the curtain to move breaks down or the curtain is clamped in the guide rail, the curtain cannot be normally closed, the air conditioner is controlled to increase the power, the influence of sunlight on the indoor temperature is reduced, and the air conditioner is enabled to refrigerate quickly. Optionally, in the case that the curtain can not be closed normally, the air conditioner is controlled to send out an error warning.

According to the control method of the air conditioning system, the preset difference is the preset temperature difference, and the preset difference is larger than or equal to 3 ℃.

For example, in a specific embodiment, the preset difference is 3 ℃, in the cooling mode, the sunlight irradiation indoor environment is determined, the difference between the irradiation temperature and the outdoor temperature is obtained, and in the case that the difference is more than 3 ℃, the curtain is controlled to be closed.

Further, on the basis of any of the above embodiments, the method further includes:

acquiring indoor temperature;

and controlling the curtain to be opened under the condition that the indoor temperature reaches the preset temperature.

The preset temperature is a preset temperature, in one embodiment, the preset temperature is less than a target temperature of the air conditioner, and when the indoor temperature reaches the preset temperature, the curtain is controlled to be opened. Even if the indoor temperature is slightly increased by the irradiation of sunlight, the increased indoor temperature is close to the target temperature of the air conditioner due to the fact that the preset temperature is lower than the target temperature of the air conditioner, and the effect of indoor environment refrigeration is prevented from being influenced.
