The invention also provides a control method of the fresh air machine and air conditioner linkage system, referring to fig. 1, in an embodiment, the fresh air machine and air conditioner linkage system provided by the invention comprises a fresh air machine and an air conditioner, and the control method comprises the following steps:
step S10, detecting outdoor humidity, and judging whether the outdoor humidity is lower than a preset value;
the control method of the fresh air fan and the air conditioner linkage system is suitable for controlling the operation of the air conditioner and the fresh air fan according to the outdoor humidity and the indoor and outdoor temperature when the indoor air conditioner is in the refrigeration mode so as to adjust the indoor environment to be in a comfortable state. In order to ensure the operation effect of the air conditioner, the operation environment of the air conditioner is usually a sealed environment, air in the sealed environment is not circulated, and the freshness of the air is insufficient. In order to increase the freshness of the indoor air, the air freshness in the sealing environment can be increased by introducing outdoor fresh air, but the temperature of the outdoor fresh air is high, and the refrigeration effect of the air conditioner can be influenced by introducing the outdoor fresh air with high temperature. In addition, the outdoor fresh air is possibly high in humidity, the outdoor fresh air with high humidity is introduced into the room, the air conditioner needs to be dehumidified firstly for cooling, and the refrigeration effect can be influenced. Especially, when the user enters into indoor air conditioner of opening from external environment, its first demand is the cooling, if this moment with outdoor high temperature and high humidity's air introduction indoor, influence refrigeration cooling effect, can reduce user experience. Therefore, the outdoor humidity is detected firstly, the preset value for judging the outdoor humidity is set, and the preset value is preset and is suitable for the numerical value of the human body comfortable health standard. And judging the detected outdoor humidity and a preset value, and determining whether the freshness of the indoor air can be increased by introducing outdoor fresh air according to a judgment result.
Step S20, when the outdoor humidity is lower than the preset value, the indoor temperature and the outdoor temperature are obtained, and the indoor temperature and the outdoor temperature are compared;
furthermore, when the detected outdoor humidity and the preset value are judged, and the obtained judgment result is that the outdoor humidity is lower than the preset value, the outdoor air is not in a high-humidity state, the refrigeration effect of the air conditioner is not influenced, and the outdoor air can be introduced into a room to increase the freshness of the indoor air. In addition, the relationship between the indoor temperature and the outdoor temperature is required to be judged so as to avoid the influence on the cooling effect and reduce the user experience when the outdoor high-temperature air is introduced into the room without starting the refrigeration and cooling. Detect indoor temperature and outdoor temperature through first temperature sensor and second temperature sensor respectively to compare this indoor temperature who detects with outdoor temperature, judge big or small relation between the two, with according to the judged result, confirm whether can introduce the new freshness that the room air increased by outdoor new trend.
And step S30, determining the operation mode of the fresh air fan and the air conditioner linkage system according to the comparison result of the indoor temperature and the outdoor temperature, and controlling the fresh air fan and the air conditioner to operate according to the operation mode so as to introduce the outdoor fresh air into the room through the air duct of the fresh air fan.
Furthermore, after the indoor temperature and the outdoor temperature are compared, the operation mode of the fresh air fan and air conditioner linkage system is determined according to the comparison result. The comparison result comprises that the indoor temperature is higher than the outdoor temperature and the indoor temperature is lower than the outdoor temperature, so that the operation mode of the fresh air fan and the air conditioner linkage system is determined according to the two comparison results, the operation of the fresh air fan and the air conditioner is controlled according to the determined operation mode, and the outdoor fresh air is introduced into the room through the air duct of the fresh air fan. The step of determining the operation mode of the fresh air machine and the air conditioner linkage system according to the comparison result of the indoor temperature and the outdoor temperature comprises the following steps:
step S31, when the indoor temperature is higher than or equal to the outdoor temperature, the operation mode of the fresh air machine and air conditioner linkage system is determined as a first operation mode;
step S32, when the indoor temperature is lower than the outdoor temperature, the operation mode of the fresh air machine and the air conditioner linkage system is determined as a second operation mode
It can be understood that, when the comparison result indicates that the indoor temperature is higher than or equal to the outdoor temperature, indicating that the temperature of the indoor environment is higher, it can be presumed that the primary requirement of the user is to lower the indoor temperature. Meanwhile, the outdoor temperature is low, and the outdoor humidity is lower than a preset value, so that outdoor fresh air can be introduced, and the comfort is rapidly increased. And determining the operation mode of the fresh air machine and the air conditioner linkage system as a first operation mode according to the comparison result. And when the comparison result shows that the indoor temperature is lower than the outdoor temperature, the indoor environment temperature is lower than the outdoor environment temperature, the indoor environment temperature is reduced through air-conditioning refrigeration, and the human body feels more comfortable. At the moment, the outdoor temperature is high, outdoor fresh air is introduced indoors, and the comfort degree of a human body is influenced when the fresh air is blown to the human body. Thereby can set up and avoid the human body to blow or carry out cooling treatment to the outdoor new trend of introduction to increase human comfort level. And determining the operation mode of the fresh air machine and the air conditioner linkage system as a second operation mode according to the comparison result. And then according to the first running mode or the second running mode confirmed, control the operation of new fan and air conditioner, its concrete step is:
step S33, when the operation mode is the first operation mode, controlling the fresh air machine and the air conditioner to operate in the first operation mode, and detecting whether the indoor temperature is lower than the outdoor temperature;
and step S34, when the indoor temperature is lower than the outdoor temperature, the operation mode of the fresh air fan and air conditioner linkage system is switched to a second operation mode, and the fresh air fan and the air conditioner are controlled to operate in the second operation mode.
When the operation mode is determined to be the first operation mode, the fresh air fan and the air conditioner are controlled to operate in the first operation mode, the air conditioner is started to refrigerate, outdoor fresh air is introduced, and therefore the freshness of indoor air is increased while the indoor temperature is reduced. And detecting the indoor temperature and the outdoor temperature, and judging whether the indoor temperature is reduced to be lower than the outdoor temperature after the air conditioner performs refrigeration and cooling. When the temperature is lower than the outdoor temperature, the indoor air temperature is reduced to meet the requirement of human comfort level, the operation mode of the fresh air fan and air conditioner linkage system is switched to the second operation mode, the fresh air fan and the air conditioner are controlled to operate in the second operation mode, the air conditioner continuously performs refrigeration operation, outdoor fresh air is cooled or introduced indoors after air supply is adjusted, the high-temperature outdoor fresh air is prevented from being blown to a human body, and the user comfort level is improved. And when the indoor temperature and the outdoor temperature are detected and the indoor temperature is determined to be lower than the outdoor temperature, the operation mode is directly determined to be the second operation mode, and the second operation mode is switched to without being cooled in the first operation mode. When the operation mode is determined to be the second operation mode, the fresh air machine and the air conditioner are controlled to operate in the second operation mode, the air conditioner is started to refrigerate, outdoor fresh air is cooled or introduced into a room after air supply is adjusted, so that the indoor temperature is reduced, meanwhile, the freshness of indoor air is increased, and the comfort of a user is improved.
Further, in a second embodiment of the control method of the fresh air machine and air conditioner linkage system according to the present invention, the step of controlling the fresh air machine and the air conditioner to operate in the first operation mode includes:
and step S331, starting an air conditioner refrigeration mode to operate for a preset time, and controlling a fresh air machine to operate when the preset time is reached so as to introduce outdoor fresh air.
When the operation mode of the fresh air fan and air conditioner linkage system is the first operation mode, it is indicated that the indoor temperature is higher than the outdoor temperature, and the indoor temperature needs to be cooled first. Therefore, the air conditioner refrigeration mode is started firstly, and the air conditioner runs for a preset time in the refrigeration mode. The preset time is preset according to the cooling temperature, the indoor area and the refrigerating intensity, and when the indoor area is larger and the refrigerating intensity is stronger, the preset time required for reaching the cooling degree is shorter; the smaller the corresponding indoor area is, the weaker the refrigeration intensity is, and the longer the preset time required for reaching the temperature reduction degree is. When the air conditioner cooling mode is started to operate for a preset time, the indoor temperature is reduced to a reduced temperature, for example, the temperature of the indoor air is reduced to 22 ℃ from 28 ℃ to 6 ℃, and then the operation of the fresh air machine is controlled, and indoor fresh air is introduced to increase the freshness of the indoor air. Because outdoor humidity is less than the default, humidity is not high, can not influence indoor cooling. And in the refrigeration operation, the outdoor fresh air is introduced after the indoor temperature is reduced, so that the influence on the cooling effect of the initial indoor temperature is avoided, and the user experience is improved.
Further, in a third embodiment of the control method of the fresh air machine and air conditioner linkage system according to the present invention, the step of controlling the fresh air machine and the air conditioner to operate in the first operation mode includes:
and step S332, starting an air conditioner refrigeration mode to operate at the maximum frequency, and controlling the circulation in the fresh air machine to operate at the maximum rotating speed.
Further, when the operation mode of the fresh air fan and air conditioner linkage system is the first operation mode, it indicates that the indoor temperature is higher than the outdoor temperature, and the indoor temperature needs to be cooled first. Therefore, the air-conditioning refrigeration mode is started, and the operation frequency of the air-conditioning refrigeration mode is started to be the maximum in consideration of the fastest cooling speed. The refrigeration mode runs at the maximum running frequency which is substantially the maximum running frequency of the compressor, and the refrigerant flows rapidly, so that the indoor hot air can be rapidly ventilated and rapidly cooled. Meanwhile, the fresh air fan is arranged at the indoor air inlet of the indoor side and the air outlet of the indoor side, indoor air can be introduced into the fresh air fan, and internal circulation is formed. The inner circulation drives the indoor air to flow through the wind wheel of the fresh air machine, and an indoor wind field is formed. The larger the wind field is, the better the refrigeration and cooling effects of the air conditioner are, namely, the faster the cooling is. Therefore, the fresh air machine is controlled to operate at the maximum rotating speed so as to accelerate the rotating speed of the wind wheel, and the maximum amount of wind is introduced into the fresh air machine to drive the indoor air to flow. In addition, the internal circulation can also be realized through the air conditioner, and the air inlet of the air conditioner introduces indoor air and then comes out from the air outlet to drive the indoor air to flow to form a wind field so as to rapidly cool.
The solution of the third embodiment may also be combined with the solution of the second embodiment to further increase the cooling speed. When the air-conditioning refrigeration mode is started to operate for the preset time, the air-conditioning refrigeration mode operates at the maximum frequency, the inner circulation of the fresh air machine is controlled to operate at the maximum rotating speed, and when the air-conditioning operation reaches the preset time, the fresh air machine is controlled to introduce outdoor fresh air, so that the freshness of indoor air is improved while the rapid cooling is realized.
Further, in a fourth embodiment of the method for controlling a fresh air machine and air conditioner linkage system according to the present invention, the fresh air machine and air conditioner linkage system includes a pre-refrigeration device, and the step of controlling the fresh air machine and the air conditioner to operate in the first operation mode includes:
and S333, starting an air conditioner refrigeration mode, controlling a fresh air fan to operate, and introducing outdoor fresh air into a room after the outdoor fresh air passes through the pre-refrigeration device.
Furthermore, when the operation mode of the fresh air fan and air conditioner linkage system is the first operation mode, it indicates that the indoor temperature is higher than the outdoor temperature, and the indoor temperature needs to be reduced first. Thereby open air conditioner refrigeration mode earlier, cool down indoor, consider indoor confined space in addition, the air is more turbid to open the operation of the new fan of air conditioning refrigeration while control, with the outdoor new trend of introduction. Because of during first mode of operation, indoor temperature is higher, and the cooling is the factor of considering first, for making the outdoor new trend of introduction not influence the cooling, can carry out prefabricated cold processing with outdoor new trend. Be provided with the prefabricated cold charge in the wind channel of new trend machine, outdoor new trend gets into indoorly after carrying out temperature reduction through the prefabricated cold charge, avoids cooling the outdoor air of introduction through the air conditioner.
The solution of the fourth embodiment may also be combined with the solution of the third embodiment to further increase the cooling speed. When the air-conditioning refrigeration mode is started, the air-conditioning refrigeration mode operates at the maximum frequency, the fresh air machine is controlled to operate at the maximum rotating speed in an internal circulation mode, the fresh air machine is controlled to operate, the introduced outdoor fresh air is introduced into a room through the cooling of the pre-cooling device, and the freshness of the indoor air is improved while the rapid cooling is realized.
Further, in a fifth embodiment of the method for controlling a fresh air machine and an air conditioner linkage system according to the present invention, the step of controlling the fresh air machine and the air conditioner to operate in the second operation mode includes:
and step S341, controlling the fresh air fan to rotate at a reduced speed or controlling an air outlet of the fresh air fan to disperse air.
When the indoor temperature is lower than the outdoor temperature and the operation mode of the fresh air fan and air conditioner linkage system is the second operation mode, the temperature of the indoor environment is reduced to meet the requirement of human comfort. The outdoor new trend of introduction is greater than ambient temperature, blows to indoor with the new trend of this high temperature, arouses indoor local temperature to rise, influences human comfort level to this embodiment is provided with the mechanism that reduces the air supply distance, and the outdoor new trend of messenger's introduction blows the distance shorter, can not blow the human body. The air supply distance can be reduced by reducing the rotating speed of the fresh air fan or controlling the air outlet of the fresh air fan to disperse air outlet. The lower the rotation speed of the fresh air fan, the weaker the driving force for driving the operation of the air, and the weaker the driving force, the shorter the air blowing stroke, thereby reducing the air blowing distance. And the scattered air outlet of the air outlet enables the air outlet to be divided into a plurality of strands of thin flows, the spreading distance of the thin flows is shortened along with the attenuation of the wind speed, and the air supply distance is reduced. The air outlet can be provided with a grid net, and the grid net is pushed to move by the pushing device. When air needs to be dispersed and exhausted, the pushing device pushes the grid net to be located at the air outlet, and dispersed air exhaust is achieved. When the air does not need to be dispersed, the pushing device pushes the grid net to be far away from the air outlet, so that the dispersed air outlet is avoided. Through this mode of reducing rotational speed or control new fan air outlet dispersion air-out, reduce the air supply distance, avoid outdoor hot-blast to blow to the human body, improve user's comfort level.
Further, in a sixth embodiment of the method for controlling a fresh air machine and air conditioner linkage system according to the present invention, the step of controlling the fresh air machine and the air conditioner to operate in the second operation mode includes:
and step S342, detecting the position of the human body, and controlling an air outlet of the fresh air machine to avoid the air outlet of the human body.
Further, in order to avoid the introduced fresh air with higher outdoor temperature from blowing to the human body, an infrared detection device can be arranged in the fresh air fan and air conditioner linkage system through the introduction of the fresh air, and the position of the human body is detected through the infrared detection device. According to the human body position, the air outlet of the fresh air machine is controlled to avoid the human body position for air outlet, and therefore outdoor hot air is prevented from blowing to the human body.
The solution of the sixth embodiment may also be combined with the solution of the fifth embodiment to further avoid the hot wind from blowing to the human body. When the fresh air machine is controlled to operate at a reduced rotating speed or the air outlet of the fresh air machine is controlled to disperse air outlet, the position of a human body is detected, and the air outlet of the fresh air machine is controlled to avoid the position of the human body for air outlet. Reduce the air supply distance on the one hand, on the other hand avoids human air-out to ensure to avoid human air-out, improve user's comfort level when introducing outdoor new trend and improving indoor air freshness.
Further, in a seventh embodiment of the control method of the fresh air machine and air conditioner linkage system according to the present invention, the step of controlling the fresh air machine and the air conditioner to operate in the second operation mode includes:
and S343, introducing the outdoor fresh air into the room after passing through the pre-refrigeration device.
