the air conditioner comprises a heat exchanger, wherein a heat exchange pipe extends out of the heat exchanger, the heat exchange pipe is partially arranged in an air duct, and the control device controls the working state of the heat exchange pipe according to the temperature of an air inlet detected by the temperature sensor.
The fresh air machine and air conditioner linkage system comprises the fresh air machine and an air conditioner, wherein the fresh air machine is integrated in an indoor machine of the air conditioner, an air inlet and an air outlet which are communicated through an air duct are formed in the fresh air machine, the air inlet is formed in the outdoor side, and the air outlet is formed in the indoor side. The air inlet can introduce fresh air outside the room into the air channel and enter the room through the air outlet. The fresh air machine and air conditioner linkage system also comprises a control device, and a first detection device, a second detection device, a first humidity sensor, a second humidity sensor and a temperature sensor which are connected with the control device; the temperature sensor is positioned at an air inlet of the fresh air machine, the first detection device, the second detection device, the first humidity sensor, the second humidity sensor and the control device can be arranged in the air conditioner or the fresh air machine, when the temperature sensor is arranged in the air conditioner, the first detection device, the first humidity sensor and the control device are positioned in an indoor unit of the air conditioner, and the second detection device and the second humidity sensor are positioned in an outdoor unit of the air conditioner. When the fresh air machine is arranged in the fresh air machine, the first detection device, the first humidity sensor and the control device are positioned on the indoor side of the fresh air machine, and the second detection device and the second humidity sensor are positioned on the outdoor side of the fresh air machine. The first detection device and the first humidity sensor are respectively used for detecting the indoor air index and the indoor humidity, and the second detection device and the second humidity sensor are respectively used for detecting the outdoor air index and the outdoor humidity. The air index is an index for quantitatively describing the air quality condition, the main detected pollutants are fine particles, inhalable particles, sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide and the like, and the larger the numerical value is, the higher the content of the pollutants in the air is, the more serious the pollution condition is, and the greater the harm to the health of a human body is. The first detection device collects indoor air, and various components in the collected indoor air are analyzed to obtain the content of the various components so as to determine the indoor air index. The corresponding second detection device collects the outdoor air, and various components in the collected outdoor air are analyzed to obtain the content of the various components so as to determine the outdoor air index. The first humidity sensor and the second humidity sensor detect the indoor humidity and the outdoor humidity by collecting the indoor air and the outdoor air and determining the content of water vapor therein. And determining the indoor air quality and the outdoor air quality according to the detected indoor air index, outdoor air index, indoor humidity and outdoor humidity. Under the conditions that the indoor air quality is poor and dry, and the outdoor air quality is good and moist, the controllable fresh air fan is started to introduce outdoor fresh air, and the indoor air is purified and humidified through the outdoor fresh air. The fresh air machine is provided with a starting motor and fan blades, and is in a standby state when outdoor fresh air does not need to be introduced. When outdoor fresh air needs to be introduced, the starting motor is controlled to start, the fan blades are driven to rotate, and the outdoor fresh air is introduced into the room through the air inlet, the air outlet and the air channel communicated with the air inlet and the air outlet.
In addition, the temperature difference between the outdoor environment and the indoor environment is considered to be large, for example, the indoor air conditioner is in a heating or cooling state, and the outdoor fresh air temperature is low or high. When the outdoor fresh air is introduced, the indoor local temperature can be greatly changed, the indoor air conditioning effect is reduced, and the comfort of a human body is influenced. Therefore, the fresh air fan and air conditioner linkage system is provided with a temperature sensor for detecting the temperature of the fresh air inlet, and a heat exchange pipe partially arranged in the air duct extends out of the heat exchanger. The temperature sensor is positioned outside the room and close to the fresh air inlet, so that the temperature detection of the air inlet is more accurate. When the temperature sensor detects that the temperature of the air inlet is lower than a certain value or higher than a certain value, the temperature of the outside fresh air is lower or higher, and the heat exchange tube is controlled to be started to work. The fresh air machine is started to operate to introduce outdoor fresh air, and the outdoor fresh air passes through the heat exchanger and the heat exchange of the heat exchanger to improve or reduce the temperature of the outdoor fresh air entering the room. The introduced outdoor fresh air passes through the heat exchanger according to the detection result of the temperature of the air inlet, so that the temperature difference between the outdoor fresh air and the indoor air is reduced, and the comfort of a human body is improved.
Furthermore, an electromagnetic valve is arranged on the heat exchange tube, and when the electromagnetic valve is opened, the refrigerant in the heat exchanger flows to the heat exchange tube.
The electromagnetic valve is arranged on the heat exchange tube, and when the electromagnetic valve is electrified and conducted, a refrigerant in the heat exchanger flows to the heat exchange tube; when the electromagnetic valve is cut off when power is lost, the refrigerant in the heat exchanger can not flow to the heat exchange tube. Because the heat exchange tube part sets up in the wind channel, when the solenoid valve switched on, the external new trend through the wind channel can carry out the heat transfer with the heat exchange tube. When the indoor air conditioner heats, the temperature sensor detects that the temperature of the air inlet is low, which shows that the temperature of the external fresh air is low, the control solenoid valve is switched on, the heat exchange tube works, and the temperature of the external fresh air is improved by exchanging heat with the heat exchange tube. When the indoor air conditioner refrigerates, the temperature sensor detects that the temperature of the air inlet is higher, which shows that the temperature of the external fresh air is higher, the control solenoid valve is conducted, the heat exchange tube works, and the fresh air with higher external temperature exchanges heat with the heat exchange tube, so that the temperature of the fresh air is reduced. Through exchanging heat between the outside fresh air and the heat exchanger, the temperature difference between the outdoor fresh air and the indoor air is reduced, and the comfort level of a human body is improved. When the temperature sensor detects that the temperature of the air inlet and the indoor temperature are not greatly different, the introduced outdoor fresh air is not required to be heated, the electromagnetic valve is controlled to be powered off, the heat exchange tube does not work, the external fresh air is directly introduced into the room through the air duct, and the indoor air is purified and humidified.
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 an indoor air index, an outdoor air index, indoor humidity and outdoor humidity;
the control method of the fresh air fan and air conditioner linkage system is suitable for introducing outdoor fresh air for purification and humidification under the condition of poor indoor air quality so as to improve the air quality of the indoor environment. Before introducing outdoor fresh air, an air index and air humidity which represent the air quality are detected. Detect indoor air index through first detection device, second detection device detects outdoor air index, and first humidity transducer detects indoor humidity, and second humidity transducer detects outdoor humidity to according to the indoor outer air index and the indoor outer humidity that detect, carry out the air quality of indoor side and the air quality judgement of outdoor side, confirm whether to introduce outdoor new trend.
Step S20, when the indoor air index is larger than a first preset value and larger than the outdoor air index, and the outside and inside humidity is smaller than a second preset value and smaller than the outdoor humidity, judging whether the air inlet temperature of the fresh air fan is smaller than a first preset temperature or larger than a second preset temperature;
in order to judge the quality of the air index and the level of the air humidity, the present embodiment is provided with a first preset value for judging the air index and a second preset value for judging the air humidity, and the first preset value and the second preset value are preset and are suitable for the values of the human body comfort and health standard. When the indoor air index is larger than the first preset value, the pollutant in the indoor air is too high, and the human health is influenced; when the humidity is smaller than the second preset value, the indoor air is too dry, and the human body comfort is poor. And comparing the indoor air index detected by the first detection device with the outdoor air index detected by the second detection device by using a first preset value respectively, and judging the size relationship. When the indoor air index is greater than the first preset value and greater than the outdoor air index, indicating that pollutants in the indoor air are higher and exceed the standard value; if the outdoor air index is smaller than the outdoor air index, the pollutants in the outdoor air are smaller than those in the room, and the outdoor air quality is better than that in the room. And when the indoor air index is less than or equal to the first preset value, the pollutants in the indoor air are less, and the indoor air does not need to be purified. When the indoor air index is greater than the first preset value and is not greater than the indoor air index, the pollutant in the indoor air is higher and exceeds the standard value, but the outdoor air quality is worse, the outdoor air cannot be purified through introducing, and the indoor air can be purified by arranging the purifying device indoors. Meanwhile, when the indoor humidity is smaller than a second preset value and smaller than the outdoor humidity, the indoor air is over-dry; and the outdoor humidity is greater than the indoor humidity, and the outdoor air is more humid than the indoor air. And when the indoor humidity is greater than or equal to the second preset value, the indoor air is humid, and humidification is not needed. When indoor humidity is less than the second preset value, when not less than outdoor humidity, then explain that indoor air is too dry, but outdoor humidity is lower, can not carry out the humidification through introducing outdoor air, and the accessible sets up humidification device at indoor and carries out the humidification to indoor air. And when the indoor air index is greater than the first preset value and is greater than the outdoor air index, and the indoor humidity is less than the second preset value and is less than the outdoor humidity, can introduce better and more humid outdoor air of quality to indoor, purify the humidification to indoor air. In addition, when outdoor fresh air is introduced, the temperature difference between the outdoor environment and the indoor environment is large, if the indoor air conditioner is in a heating or cooling state, the temperature of the outdoor fresh air is low or high, and when the outdoor fresh air with low or high temperature is introduced, the effect of the indoor air conditioner can be reduced, and the comfort of a human body is influenced. Therefore, when outdoor fresh air is introduced, the temperature of the air inlet is detected, and whether the temperature is smaller than the first preset temperature or larger than the second preset temperature is judged. The first preset temperature is used for judging the temperature of the air inlet in the heating state of the air conditioner, and the second preset temperature is used for judging the temperature of the air inlet in the cooling state of the air conditioner, which are all preset according to the human body comfortable temperature acceptable by most people, for example, the first preset temperature is set to be 28 ℃ in the heating state, and the second preset temperature is set to be 22 ℃ in the cooling state. And determining whether the temperature of the outdoor fresh air needs to be increased or decreased according to the temperature of the air inlet and the judgment result of the first preset temperature or the second preset temperature so as to ensure the comfort level of the human body.
And step S30, when the temperature of the air inlet of the fresh air fan is lower than the first preset temperature or higher than the second preset temperature, the heat exchange pipe is started to work, and the fresh air fan is started to operate so as to introduce outdoor fresh air.
Further, when the temperature of the air inlet of the fresh air fan is judged to be lower than the first preset temperature or higher than the second preset temperature, the temperature of the introduced external fresh air is lower or higher, and the introduced external fresh air needs to be subjected to heat exchange through the heat exchange tube, so that the temperature of the introduced external fresh air is increased or decreased. Thereby controlling the opening of the heat exchange tube to work, and enabling outdoor fresh air entering through the air duct to exchange heat through the heat exchange tube. The introduced outdoor fresh air is subjected to heat exchange and then enters the room to humidify and purify the indoor air, the outdoor fresh air and the heat exchange tube are subjected to heat exchange, so that the temperature of the introduced outdoor fresh air is not greatly different from the original indoor air temperature, and the influence of the introduced fresh air with large temperature difference on the comfort of a human body is avoided.
According to the control method of the fresh air fan and air conditioner linkage system, the indoor air index, the outdoor air index and the first preset value are detected to be judged, and the indoor humidity, the outdoor humidity and the second preset value are judged; when the indoor air index is larger than a first preset value and larger than an outdoor air index, and the indoor humidity is smaller than a second preset value and smaller than the outdoor humidity, further judging whether the temperature of an air inlet of the fresh air fan is smaller than a first preset temperature or larger than a second preset temperature; when the air inlet temperature of the fresh air machine is smaller than the first preset temperature or larger than the second preset temperature, the heat exchange tube is opened to work, the fresh air machine is started to operate, the introduced outdoor fresh air and the introduced outdoor fresh air are subjected to heat interaction through the heat exchange tube and then blown to the indoor, and the indoor air is purified and humidified. The introduction of outdoor fresh air to humidify and purify indoor air is realized, and the comfort level of a human body is improved.
Further, in another embodiment of the control method of the fresh air machine and air conditioner linkage system of the invention, the heat exchange pipe is provided with an electromagnetic valve,
the step of starting the heat exchange tube to work and starting the fresh air fan to operate comprises the following steps:
step S31, controlling the electromagnetic valve to be electrified and conducted so as to enable the refrigerant in the heat exchanger to flow to the heat exchange tube;
and step S32, detecting whether the temperature of the air inlet is higher than a first preset temperature or lower than a second preset temperature, and starting the fresh air fan to operate at the maximum rotating speed when the temperature of the air inlet is higher than the first preset temperature or lower than the second preset temperature.
Furthermore, the heat exchange tube is provided with an electromagnetic valve, when the electromagnetic valve is electrified and conducted, the refrigerant in the heat exchanger flows to the heat exchange tube, and the heat exchange tube works; when the electromagnetic valve is cut off when power is lost, the refrigerant in the heat exchanger can not flow to the heat exchange tube, and the heat exchange tube does not work. When the temperature of the air inlet of the fresh air fan is detected to be lower than the first preset temperature or higher than the second preset temperature, the temperature difference between the outdoor fresh air and the indoor temperature is large, and the fresh air and the indoor temperature need to be subjected to heat exchange through the heat exchange tube. Therefore, the electromagnetic valve is controlled to be electrified, the heat exchange tube works, and the heat exchange tube is partially arranged in the air channel and can exchange heat with external fresh air passing through the air channel and the air channel. Specifically, when the indoor air conditioner heats, the temperature sensor detects that the temperature of the air inlet is lower than a first preset temperature, the external temperature is lower, the electromagnetic valve is controlled to be conducted, the heat exchange tube works, the heat exchange tube is partially arranged in the air duct and exchanges heat with the air inlet of the air duct, and the temperature of the air inlet is improved. When the indoor air conditioner refrigerates, the temperature sensor detects that the temperature of the air inlet is higher than a second preset temperature, the temperature of the outside fresh air is higher, the electromagnetic valve is controlled to be conducted, the heat exchange pipe works, the heat exchange pipe is partially arranged in the air channel and exchanges heat with the air inlet of the air channel, and the temperature of the air inlet is reduced. When the temperature of the air inlet is detected to be increased to be higher than a first preset temperature or reduced to be lower than a second preset temperature, the temperature difference between the air inlet and the indoor air is small, the fresh air fan is started to operate at the maximum rotating speed, and outdoor fresh air is introduced into the room after being subjected to heat exchange through the heat exchanger. The fresh air machine can be operated at the maximum rotating speed to introduce outdoor fresh air quickly, ventilate indoor air, introduce outdoor high-quality and high-humidity fresh air indoors, and purify and humidify the indoor air.
Further, referring to fig. 2, on the basis of the first embodiment of the method for controlling a fresh air blower and air conditioner linkage system of the present invention, a second embodiment of the method for controlling a fresh air blower and air conditioner linkage system of the present invention is provided, and in the second embodiment, the step of determining whether the temperature of the air inlet of the fresh air blower is less than the first preset temperature or greater than the second preset temperature includes:
step S40, when the temperature of the air inlet of the fresh air fan is higher than a first preset temperature or lower than a second preset temperature, controlling the electromagnetic valve to lose power and cut off, and the heat exchange pipe does not work;
and step S50, starting the fresh air fan to run at the maximum rotating speed so as to introduce outdoor fresh air.
Further, before the fresh air fan is started to introduce outdoor fresh air, the temperature of the air inlet is detected, the temperature of the air inlet is possibly higher than a first preset temperature or lower than a second preset temperature, namely, the difference between the outdoor temperature and the indoor temperature is not large. Therefore, when the temperature of the air inlet is higher than the first preset temperature or lower than the second preset temperature, the temperature of outdoor fresh air entering from the air inlet does not need to be increased or reduced, and the outdoor fresh air can directly enter the room through an air channel between the air inlet and the air outlet of the fresh air fan. And starting the fresh air machine to operate at the maximum rotating speed, and introducing outdoor fresh air into the room through the air channel. The fresh air machine operates at the maximum rotating speed, introduces outdoor fresh air at the fastest speed, ventilates indoor air, introduces outdoor high-quality and high-humidity fresh air indoors, purifies and humidifies the indoor air, quickly improves the quality of the indoor air, and increases the humidity.
Further, referring to fig. 3, on the basis of the second embodiment of the method for controlling a fresh air machine and an air conditioner linkage system according to the present invention, a third embodiment of the method for controlling a fresh air machine and an air conditioner linkage system according to the present invention is provided, and in the third embodiment, the step of starting the fresh air machine to operate at the maximum rotation speed includes:
step S60, when the time length of the fresh air fan running at the maximum rotating speed reaches the preset time length, detecting whether the indoor air index is larger than a first preset value;
and step S70, when the indoor air index is larger than the first preset value, controlling the fresh air fan to continuously run at the maximum rotating speed.
Understandably, the content of the indoor air is certain, and after the fresh air fan is started to operate for a certain time at the maximum rotating speed, the quality of the indoor air can be optimized and improved, and the first preset value meeting the health requirement is achieved. Even if fresh air is introduced subsequently, the influence on the indoor air quality is not great, the service life of the fresh air fan is influenced instead by the continuous operation of the fresh air fan, and the energy consumption is increased. Therefore, the preset time length is set in the embodiment, the preset time length can be preset according to the area of the indoor space, and can also be defined by a user according to the requirement of the user. When the time length of the fresh air fan running at the maximum rotating speed reaches the preset time length, whether the indoor air index is larger than a first preset value or not is detected, if the indoor air index is larger than the first preset value, it is indicated that pollutants in the indoor air exceed the standard, and the running time length of the fresh air fan is not enough, so that the fresh air fan is controlled to run at the maximum rotating speed continuously, and outdoor fresh air is introduced quickly to be humidified and purified. And when the outdoor air index is not greater than the first preset value, the indoor air meets the requirement of health, and if the pollutants are not too much, the fresh air fan is controlled to stand by, so that the energy is saved, and the service life of the air conditioner is prolonged.
Further, referring to fig. 4, on the basis of the third embodiment of the method for controlling a fresh air blower and air conditioner linkage system of the present invention, a fourth embodiment of the method for controlling a fresh air blower and air conditioner linkage system of the present invention is provided, in the fourth embodiment, the fresh air blower and air conditioner linkage system includes an air conditioner, and the step of detecting whether the indoor air index is greater than the first preset value includes:
