Fig. 1 is a schematic diagram of a control method of a fresh air conditioner according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
According to an aspect of an embodiment of the present invention, a fresh air conditioning control method is provided, including, in a fresh air mode, acquiring an indoor and outdoor temperature difference, when the indoor and outdoor temperature difference is within a first threshold interval, turning on a purification mode, and performing opening control of a purification damper based on a fresh air gear, wherein the purification mode is used for controlling indoor air to flow back to an air conditioning purification device for purification, the purification damper is used for controlling a gas flow rate for flowing back the indoor air to the air conditioning purification device, and the purification device is used for purifying fresh air and indoor air. Wherein, the purification mode can be with indoor air and new trend introduce the mixed purification back of blowing out in the purifier. The purge damper is responsible for controlling the opening of the inlet of the indoor air intake purification device. Therefore, after the purification mode is started, indoor and outdoor air can simultaneously enter the purification device for mixed purification.
Wherein, the control of the opening of the purification air door comprises the control of the overturning opening angle of the purification air door or the control of the translation opening of the purification air door. That is, the purge damper may control the amount of the introduced indoor air based on the manner in which the tumble damper is opened with a change in the opening angle, or the amount of the introduced indoor air by the manner in which the purge damper is opened and closed by sliding in a translational manner.
Wherein, the flow of the indoor air based on new trend gear control introduction purification device is shown promptly to the upset opening angle based on new trend gear control, thereby through detecting the indoor outer difference in temperature, when the indoor outer difference in temperature is great, control opens the purification mode automatically when the new trend mode is opened to the user, and through detecting new trend wind speed gear, control purification air door upset opening angle, make new trend flow and indoor wind flow match the mixture, carry out the heat transfer alternating temperature of matching the flow to the new trend through the indoor air, realize that the indoor outer difference in temperature reduces, promote the travelling comfort. Wherein, the fresh wind gear is divided into strong wind, high wind, apoplexy and low wind gear. Wherein, the rotating speed of the fan corresponding to the strong gear is 1200-.
Specifically, when the new trend gear is powerful windscreen, control air purification door upset opening angle is first angle. Wherein the first angle is 80 ° to 90 °, i.e. the purge damper is fully open. When the overturning opening angle of the purification air door is 0 degree, the purification air door is completely closed, namely the overturning opening angle range of the purification air door is 0-90 degrees. When the turnover opening angle of the air purifying door is 80-90 degrees, the air purifying door is completely opened, the introduction amount of the indoor air is the maximum, and therefore the air conditioner can be prevented from overload operation under the condition that the air volume of the air conditioner is severely increased by mixing and purifying a large amount of indoor air and the fresh air of the powerful windshield. The heat exchange is carried out between the indoor air and the fresh air instead of directly carrying out the heat exchange on the fresh air through the heat exchanger, so that the problems of faults, overload and the like caused by the sudden increase of the load of the air conditioner can be avoided. The novel air conditioning unit has the advantages that the novel air conditioning unit is relatively mild in mode of mixing and exchanging heat between indoor air and fresh air, the load impact on the air conditioning unit is relatively small, and due to the fact that sufficient indoor air is matched with the fresh air, the blowing-out temperature of the fresh air is greatly improved, the temperature difference is reduced, and meanwhile the novel air conditioning unit is more energy-saving and reliable. Similarly, when the air purifying door is opened in a sliding and translation manner, and when the fresh air gear is a strong windshield, the air purifying door is completely opened, or the translation opening degree is 80% -100%, wherein the translation opening degree is the ratio of the opening area of the air purifying door opened in a translation manner to the opening area of the air purifying door completely opened.
When the new trend gear is high windscreen, control air purification door upset opening angle is the second angle. Wherein the second angle is 50 ° to 70 °. At the moment, the introduced indoor air is correspondingly reduced along with the reduction of the fresh air damper, so that the problem that the service life of the purifying device is prolonged and reduced due to unnecessary load increase caused by the fact that excessive air rushes into the purifying device is solved while the fresh air temperature is buffered by sufficient indoor air. Similarly, when the purification air door is opened in a sliding and translation mode and when the fresh air gear is a high windshield, the opening degree of the purification air door is 50% -70%.
When the new trend gear was well the fender, control air purification door upset opening angle was the third angle. Wherein the third angle is 20 ° to 40 °. At this moment, the introduced indoor air is further reduced along with the reduction of the fresh air windshield, so that the problem that the service life of the purifying device is prolonged and reduced due to unnecessary load increase caused by the fact that the excessive air rushes into the purifying device is avoided while the fresh air temperature is buffered by sufficient indoor air. Similarly, when the purification air door is opened for sliding and translating, and when the fresh air gear is a middle windshield, the opening degree of the purification air door is 20% -40%.
When the new trend gear is less than well windscreen, withdraw from control, the new trend amount of wind is less relatively this moment promptly, even directly blows in indoor, can not cause the perception change of indoor difference in temperature yet, need not to carry out extra intervention control to can save the control resource, simplify control logic, improve control system's stability and reliability.
Wherein the first threshold interval is from 12 to 23 ℃. Namely, when the indoor and outdoor temperature difference is between 12 and 23 ℃, the control is started, and the indoor and outdoor temperature difference is larger but not too large at the moment, so that the temperature difference belongs to the adjustable range. However, when the indoor outer difference in temperature is greater than 23 ℃, because the indoor outer difference in temperature is too big, introduce the new trend this moment and will lead to serious difference in temperature problem to, if carry out the heat transfer with the room air this moment, will make indoor temperature sharp change, consequently, make when the indoor outer difference in temperature is greater than 23 ℃, stop the introduction of outdoor new trend, perhaps with the new trend windscreen control below the well stroke fender, produce great change because the new trend of too big difference in temperature is introduced in order to avoid the indoor temperature. When the indoor and outdoor temperature difference is less than 12 ℃, the indoor and outdoor temperature difference is small, and the sensible change of the indoor temperature difference can not be caused even if the indoor temperature difference is directly introduced into the room, and extra intervention control is not needed, so that the control resources can be saved, the control logic is simplified, and the stability and the reliability of the control system are improved.
In some embodiments, before the control is started, the detection of the current running state of the air conditioner is further included. As shown in fig. 1, the above control is not being performed when the operation state in which the air conditioner is currently located is already in the purge mode, and is activated when the operation state in which the air conditioner is currently located is not in the purge mode. The control resources are saved, the control logic is simplified, and the stability and the reliability of the control system are improved.
According to another aspect of the embodiment of the invention, a fresh air conditioning control system is provided, which comprises a fresh air module, a purification module, a detection module and a control module, wherein the fresh air module and the purification module can be independently controlled.
The detection module is respectively provided with a temperature sensing bag in the outdoor fresh air inlet and on the indoor machine body, and is used for sensing fresh air temperature and indoor temperature, and the temperatures are respectively T1 and T2.
When the fresh air is started, the detection module detects the wind shield of the fresh air and transmits a signal to the control module.
The control module adaptively adjusts the opening of the purification air duct according to the fresh air gear, so that indoor air is purified and then mixed with introduced fresh air, and the comfort of users is improved.
According to another aspect of the embodiments of the present invention, a storage medium is provided, where the storage medium includes a stored program, and when the program runs, the device where the storage medium is located is controlled to execute the fresh air conditioning control method.
Therefore, the indoor and outdoor temperature difference is detected, the purification mode is automatically started when the user starts the fresh air mode, the opening of the purification air throttle is controlled by detecting the fresh air speed gear, the fresh air flow is matched with the air conditioner air flow, indoor air is mixed with introduced fresh air after being purified, and the comfort of the user is improved.
