Furthermore, the fresh air fan and air conditioner linkage system can also comprise a preheating device to preheat outdoor fresh air and then introduce the preheated fresh air into the room. When the air conditioner is used for heating, the indoor temperature is high, and the outdoor temperature is low. When introducing outdoor fresh air through new fan, can introduce indoor with outdoor low temperature new trend, arouse indoor local air suddenly drop, influence user's comfort level. Therefore, the fresh air machine and air conditioner linkage system is provided with the preheating device, the introduced outdoor fresh air is heated by the preheating device firstly, and the fresh air is blown to the indoor space after the temperature of the fresh air machine and the air conditioner is increased. The pre-heating device can be an extension capillary tube extending from the air conditioner heat exchanger, the extension capillary tube is positioned in the air duct, and the refrigerant in the heat exchanger can flow to the extension capillary tube.

The humidifying device can be a humidifying net arranged in an air duct, a water tank is arranged at the bottom of the fresh air machine, a water pump is arranged in the water tank, the water pump pumps water to the humidifying net, and outdoor fresh air or indoor air passing through the air duct is humidified.
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 indoor humidity and the indoor and outdoor temperature when the indoor air conditioner is in a heating mode so as to adjust the indoor environment to 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 low, and the heating effect of the air conditioner can be influenced by introducing the low-temperature outdoor fresh air. Especially, when the user enters into indoor air conditioner of opening from external environment, its first demand is the intensification, if indoor with outdoor microthermal new trend introduction this moment, influence the heating intensification effect, can reduce user experience. In addition, the possible humidity of indoor air is high, and the condensation of outdoor low-temperature fresh air meeting indoor high-temperature and high-humidity air subjected to heating at an air outlet of the air conditioner can also affect the heating effect. Therefore, the indoor humidity is detected firstly, the preset value for judging the indoor 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 indoor humidity and a preset value, and controlling the operation of the air conditioner and the fresh air fan according to a judgment result.
Step S20, when the indoor humidity is higher than the preset value, the indoor temperature and the outdoor temperature are obtained, and the indoor temperature and the outdoor temperature are compared;
further, when the detected indoor humidity and the preset value are judged, and the obtained judgment result shows that the indoor humidity is higher than the preset value, the indoor air is in a high-humidity state, and the heating effect of the air conditioner is influenced. The size relation of indoor temperature and outdoor temperature is further judged to avoid when indoor not yet beginning to heat the intensification, with outdoor microthermal air introduction indoor, influence intensification effect, reduce user experience. 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 lower than the outdoor temperature, the operation mode of the fresh air fan and air conditioner linkage system is determined as a first operation mode;
step S32, when the indoor temperature is higher than or equal to 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 lower than the outdoor temperature, indicating that the indoor environment is lower than the outdoor temperature, the first requirement of the user can be presumed to be increasing the indoor temperature. Meanwhile, because the outdoor temperature is high and the air in the indoor closed environment is relatively turbid, outdoor fresh air can be introduced to quickly increase the comfort. 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 higher than or equal to the outdoor temperature, the indoor environment temperature is higher than the outdoor environment temperature, the indoor environment temperature is raised through heating by the air conditioner, and the human body feels more comfortable. At the moment, the outdoor temperature is low, and the comfort of the human body is influenced when outdoor fresh air is introduced into the room and blown to the human body; the indoor humidity that this is outer because of detecting is higher than the default, and indoor humidity is higher promptly, if direct with outdoor low temperature new trend introduction indoor, meets indoor high temperature and high humidity's air, forms the condensation at air conditioner air outlet, influences the intensification effect. Thereby can set up and avoid the human body to blow or carry out the intensification processing to the outdoor new trend of introducing 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 higher than or equal to the outdoor temperature;
and step S34, when the indoor temperature is higher than or equal to 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 rapidly heat and introduce the outdoor fresh air subjected to the prefabrication heat treatment into the room, so that the indoor temperature is increased and the freshness of the indoor air is increased. And detecting the indoor temperature and the outdoor temperature, and judging whether the indoor temperature is increased to be higher than or equal to the outdoor temperature after the heating temperature of the air conditioner is increased. When being higher than or equal to outdoor temperature, then explain that indoor air temperature rises to the requirement that accords with human comfort level, then switch into the second running mode with new fan and air conditioner linked system's running mode to control new fan and air conditioner and move with the second running mode, the air conditioner is the operation of heating continuously, and to the outdoor new trend heat up and handle and adjust and introduce indoor after the air supply, in order to avoid directly introducing the indoor blowing of microthermal outdoor new trend to the human body, improve user comfort level. And when the indoor temperature and the outdoor temperature are detected and the indoor temperature is determined to be higher than or equal to the outdoor temperature, the operation mode is directly determined to be the second operation mode, and the second operation mode is switched to without the temperature rise of the first operation mode. When the operation mode is determined to be the second operation mode, the fresh air fan and the air conditioner are controlled to operate in the second operation mode, the air conditioner is started to heat, outdoor fresh air is subjected to temperature rise processing and air supply adjustment and then introduced into a room, so that the indoor temperature is increased, 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 the air conditioner heating mode to operate for a preset time, and controlling the 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, the indoor temperature is lower than the outdoor temperature, and the indoor temperature needs to be increased firstly. Therefore, the air-conditioning hot mode is started firstly and runs for a preset time under the heating mode. The preset time is preset according to the temperature rise, the indoor area and the heating intensity, and when the indoor area is larger and the heating intensity is stronger, the preset time required for reaching the temperature rise is shorter; the smaller the corresponding indoor area is, the weaker the heating intensity is, and the longer the preset time required for reaching the temperature rise is. When the air conditioner heating mode is started to operate for a preset time, the indoor temperature rises to the temperature rise degree, for example, the temperature rise degree of 22 ℃ to 28 ℃ is 6 ℃, and then the fresh air machine is controlled to operate, and indoor fresh air is introduced to increase the freshness of the indoor air. And in the heating operation preset time, after the indoor temperature rises, the outdoor fresh air is introduced, so that the phenomenon that the outdoor low-temperature fresh air meets the indoor high-temperature and high-humidity air to form condensation at the air outlet of the air conditioner to influence the temperature rising 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 heating 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 lower than the outdoor temperature, and the indoor temperature needs to be raised first. Thereby, the air-conditioning heating mode is turned on, and the operation frequency of the air-conditioning heating mode is turned on to the maximum in consideration of the fastest temperature rise. The heating mode operates at the maximum operating frequency which is substantially the maximum operating frequency of the compressor, the refrigerant flows rapidly, and the cold air in the room is rapidly ventilated and rapidly heated. 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 heating and temperature rising effect of the air conditioner is, namely, the faster the temperature rising 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 temperature rising speed. When the air conditioner heating mode is started to operate for the preset time, the air conditioner heating 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 conditioner operates for the preset time, the fresh air machine is controlled to introduce outdoor fresh air, so that the indoor air freshness is improved while the rapid temperature rise 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-heating 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 a heating mode of the air conditioner, controlling the fresh air fan to operate, and introducing outdoor fresh air into the room after the outdoor fresh air passes through the preheating 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 lower than the outdoor temperature, and the indoor temperature needs to be raised first. Therefore, the air conditioning heating mode is started firstly, the temperature of the indoor air is increased, the indoor sealed space is considered, the air is turbid, and the fresh air machine is controlled to operate when the air conditioner is started to heat so as to introduce outdoor fresh air. Because of the first operation mode, the indoor temperature is lower, and the temperature rise is the primary consideration, in order to make the introduced outdoor low-temperature fresh air not influence the heating temperature rise of the air conditioner, the outdoor fresh air can be subjected to the prefabrication heat treatment. Be provided with the preheating device in the wind channel of new trend fan, outdoor new trend gets into indoorly after the temperature risees through the preheating device, avoids raising the temperature to the outdoor air of introduction through the air conditioner, has prevented to take place the condensation between outdoor low temperature new trend and the indoor high temperature and high humidity air simultaneously, influences the air conditioner and heats up.
The solution of the fourth embodiment may also be combined with the solution of the third embodiment to further increase the temperature rising speed. When the air conditioner heating mode is started to operate, the air conditioner heating mode operates at the maximum frequency, the inner circulation of the fresh air machine is controlled to operate at the maximum rotating speed, the fresh air machine is controlled to operate, the introduced outdoor fresh air is introduced into a room through the temperature rise of the pre-heating device, and the freshness of the indoor air is improved while the rapid temperature rise 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, introducing the outdoor fresh air into the air-conditioning heat exchanger, and allowing the fresh air to enter the room after heat exchange of the heat exchanger.
When the indoor temperature is higher than or equal to 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 raised to meet the requirement of the comfort level of the human body. The introduced outdoor fresh air is less than the ambient temperature, and the low-temperature fresh air is blown to the indoor environment, so that the indoor local temperature is reduced, and the comfort level of a human body is influenced. The indoor humidity that this is outer because of detecting is higher than the default, and indoor humidity is higher promptly, if direct with outdoor low temperature new trend introduction indoor, meet indoor high temperature and high humidity's air, can take place the condensation, influence the intensification effect. Therefore, the outdoor fresh air is introduced into the air-conditioning heat exchanger, and is further introduced into the air-conditioning heat exchanger after being introduced into the air duct. Through the heat exchange with the air conditioner heat exchanger, blow to indoor after carrying out the intensification processing to the outdoor new trend of introduction, avoid directly introducing the lower new trend of outdoor temperature indoor, form the condensation at the air conditioner air outlet, 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:
step S342, introducing the fresh outdoor air into the air outlet duct of the air conditioner, mixing with the air outlet of the air conditioner, and introducing into the room.
Furthermore, in order to avoid the introduced fresh air with low outdoor temperature from blowing to the human body and mixing with the indoor air to form condensation at the air outlet of the air conditioner, the embodiment further introduces the outdoor fresh air into the air outlet duct of the air conditioner after introducing the outdoor fresh air into the air duct. The air conditioner has the advantages that the air conditioner is capable of conducting heating treatment on introduced outdoor fresh air and then blowing the fresh air indoors, the situation that the fresh air with low outdoor temperature is directly introduced indoors and blown to a.
The solution of the sixth embodiment may be combined with the solution of the fifth embodiment described above to further avoid the cold wind from outside the room blowing to the human body. When introducing outdoor fresh air, the air outlet through the wind channel introduces outdoor fresh air into the air conditioner heat exchanger, outdoor fresh air through the heat exchanger heat exchange further enters into air conditioner air-out wind channel, mixes the back with the air-out in air-out wind channel and blows to indoorly, has ensured that the temperature of outdoor fresh air risees, avoids directly introducing the lower fresh air of outdoor temperature indoorly, touch the air of indoor high temperature and high humidity and form the condensation at air conditioner air outlet, can prevent to arouse simultaneously that indoor local temperature reduces, improve user comfort level.
