Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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.
In consideration of the problems, in some schemes, the bypass switch is directly controlled through indoor and outdoor temperature differences, the bypass function is directly opened when the temperature difference accords with a preset value, the energy saving time is short, the air quality problem is not considered, and the energy saving effect is weak and the user experience is poor. There are some proposals to add CO on the basis of the proposal 2 Content determination, when temperature difference and CO exist 2 When the contents all accord with the preset values, the bypass function is opened, but the time for entering energy saving is still short, and the energy saving effect is still weak. Other schemes are used for judging temperature difference and CO 2 On the basis of whether the content meets the preset value or not, the air supply fans are integrated into one, so that the air is further reducedThe power consumption of the equipment is adjusted, but the problems of short time for entering the bypass and weak energy-saving effect are still not solved.
It can be seen that the control method for the "bypass" function of the air conditioning apparatus in the related scheme needs to be perfected, for example: the bypass inlet time is short, the energy-saving effect is not obvious, the quality of the air after the bypass function is started can not reach the standard, and the like, and research and solution are needed urgently. In addition, the bypass time is short, and in most cases, air entering the room still needs to pass through the filter device, which results in a fast loss of life of the filter device.
In addition, in view of the basic functions of the air conditioning equipment in adjusting the air quality and the air temperature and humidity, the invention provides a control method of the air conditioning equipment, in particular an energy-saving control method of the air conditioning equipment.
The basic functions of the air conditioning apparatus for adjusting the air quality and the air temperature and humidity will be explained below by way of example.
Air conditioning equipment conditions air quality by treating the portion of outside air entering the room by some method, such as filtration, ionization, heating, and most of which are not controllable. Such as: filtration, provided that there is a filter medium capable of removing CO from the air 2 The concentration is filtered to below 800PPM (i.e., parts per million), then 1000PPM and 1500PPM of air passes through the media, and the CO comes out 2 The concentration is basically within a certain interval of below 800 almost, so the air quality after the air conditioning equipment treatment is considered to be a fixed value, namely, is not adjustable.
The air conditioning equipment adjusts the temperature and humidity of air and processes the air through a heat exchange device, a humidifying device or a dehumidifying device. The heat exchange is the heat exchange between the air to be processed and the refrigerant, and the temperature of the refrigerant can be regarded as being controlled by the air conditioning equipment and is controllable, so the temperature and the humidity of the air processed by the air conditioning equipment are regarded as controllable values.
According to an embodiment of the present invention, there is provided a control method of an air conditioning apparatus, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The air conditioning equipment is provided with a fan, a bypass air valve, an air conditioning air valve and an air conditioning device. The air outside the room is divided into two paths after being sucked by the fan: one path of air enters the indoor side after passing through the bypass air valve, and the other path of air enters the indoor side after passing through the air regulating air valve and the air regulating device. Specifically, the air outside the air conditioning equipment is divided into two paths after being sucked into the air conditioning equipment by the fan: and one path of air enters the indoor side of the air conditioning equipment after passing through the bypass air valve, and the other path of air enters the indoor side of the air conditioning equipment after passing through the air conditioning air valve and the air conditioning device.
For example: to better illustrate the implementation of the solution of the invention, an example working procedure of a simplified air conditioning plant is presented below. Fig. 7 is a schematic structural diagram of an embodiment of an air conditioning apparatus. As shown in fig. 7, the outdoor air in the main air intake channel is sucked into the air conditioning equipment by the fan, and the main intake air is obtained. The total air inlet is divided into two paths: one path is a bypass ventilation channel which is used as bypass ventilation and directly enters the room through a bypass air valve. And the other path of the air conditioning air is taken as air conditioning air to be conditioned, and the air conditioning air passes through the air conditioning air valve and the air conditioning device in sequence and becomes treated air conditioning air to enter the room.
The control method of the air conditioning apparatus includes: step S110 to step S140.
At step S110, an air quality parameter of the indoor side is acquired, and a control instruction of a user of the air conditioning apparatus is acquired. The air quality parameters comprise carbon dioxide concentration, PM2.5 concentration and the like. The control instruction is, for example, a temperature control instruction, a humidity control instruction, and the like.
In step S120, according to the air quality parameter, determining a target opening degree of the bypass damper as a first opening degree, determining a target opening degree of the air-conditioning damper as a second opening degree, and determining a target power of the fan.
In step S120, according to the air quality parameter, a specific process of determining a target opening degree of the bypass damper as a first opening degree, determining a target opening degree of the air conditioning damper as a second opening degree, and determining a target power of the fan is described, as shown in the following exemplary description.
The following further describes, with reference to a flowchart of an embodiment of determining the first opening degree of the bypass damper and the second opening degree of the air conditioning damper in the method of the present invention shown in fig. 2, a specific process of determining the first opening degree of the bypass damper and the second opening degree of the air conditioning damper in step S120, including: step S210 to step S230.
Step S210, according to a first relation among the carbon dioxide concentration of the mixed air, the carbon dioxide concentration of the side ventilation air, the carbon dioxide concentration of the air conditioning air, the air intake of the side ventilation air, the air intake of the air conditioning air and the rated carbon dioxide concentration; according to a second relation between the PM2.5 concentration of the mixed air, the PM2.5 concentration of the side ventilation air, the PM2.5 concentration of the air conditioning air, the air inlet volume of the bypass air, the air inlet volume of the air conditioning air and the rated PM2.5 concentration; and determining the air inlet amount of the bypass air and the air inlet amount of the air conditioning air according to a third relation among the required air amount, the air inlet amount of the bypass air and the air inlet amount of the air conditioning air.
And step S220, determining the target power of the fan according to the required air volume.
And step S230, determining the target opening degree of the bypass air valve as a first opening degree and determining the target opening degree of the air-conditioning air valve as a second opening degree according to the required air quantity, the bypass air intake quantity and the air-conditioning air intake quantity.
