Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a new fan system.
In the embodiment of the invention, the fresh air fan system comprises a fresh air fan, wherein the fresh air fan comprises an air outlet arranged indoors, an air inlet arranged outdoors and an air channel communicated with the air inlet and the air outlet; the fresh air fan system also comprises a first detection device for detecting the indoor air index, a second detection device for detecting the outdoor air index, a first humidity sensor for detecting the indoor humidity, a second humidity sensor for detecting the outdoor humidity, a temperature sensor for detecting the temperature of the air inlet, a fresh air heater and a control device;

The fresh air fan system comprises a fresh air fan, wherein an air inlet and an air outlet which are communicated through an air duct are formed in the fresh air fan, 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 fan system is also provided with a first detection device, a second detection device, a first humidity sensor, a second humidity sensor and a fresh air heater which are connected with the control device, wherein the first detection device, the first humidity sensor and the control device are positioned indoors, the first detection device and the first humidity sensor are respectively used for detecting an indoor air index and indoor humidity, and the second detection device and the second humidity sensor are positioned outdoors and are respectively used for detecting an outdoor air index and outdoor humidity; the fresh air heater is positioned at the air inlet to heat the air inlet. 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 possibly large, for example, the indoor is in a heating, heating or warming state in winter, and the outdoor fresh air temperature is low. When outdoor fresh air with lower temperature is introduced, the indoor local temperature can be suddenly reduced, the indoor heating effect is reduced, and the comfort of a human body is influenced. Therefore, the fresh air fan system is provided with the fresh air heater and the temperature sensor for detecting the temperature of the fresh air inlet, and the fresh air heater and the temperature sensor are both located on the outdoor side and close to the position of 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, the temperature of the external fresh air is lower, so that the fresh air heater is started to heat the air inlet, and the temperature of the external fresh air entering the room is increased. The air conditioner is also suitable for the indoor refrigeration in summer, and a fresh air heater for heating the air inlet is changed into a refrigeration device for refrigerating the air inlet during refrigeration, such as a device with ice blocks. When the temperature sensor detects that the temperature of air intake is higher than a definite value, then explain that external fresh air temperature is higher, start refrigerating plant and lower the temperature to the air intake to reduce and get into indoor external air temperature, improve human comfort level, and avoid the refrigeration of the outdoor new trend of drawing in to new fan, reduce the waste of refrigeration energy consumption. This embodiment explains the scene that indoor ambient temperature is higher than outdoor ambient temperature, and controlling means controls the operating condition of new trend heater according to the air intake temperature that temperature sensor detected. When the temperature of the air inlet is far lower than the comfortable temperature of a human body, controlling a heater of the fresh air fan to start to work, and heating the air inlet; when the temperature of the air inlet and the comfortable temperature of the human body are not greatly different, the heater of the new fan is not started, and external new air is directly introduced through the air inlet. The introduced outdoor fresh air is processed according to the detection of the temperature of the air inlet, so that the difference between the temperature of the outdoor fresh air and the temperature of the indoor air is reduced, and the comfort of a human body is improved.
Further, the fresh air fan system further comprises an air conditioner, and the fresh air fan is integrated in the air conditioner indoor unit.
The new fan of this embodiment can the exclusive use introduce outdoor new trend, also can match the air conditioner and use together. When the air conditioner is matched, in order to reduce the space occupation, the new fan is integrated in the space of the indoor unit of the air conditioner, and the first detection device, the first humidity sensor, the second detection device, the second humidity sensor and the control device in the new fan system can be positioned in the air conditioner or the new fan. When the air conditioner is positioned in the air conditioner, the first detection device, the first humidity sensor and the control device are positioned in the indoor unit of the air conditioner, and the second detection device and the second humidity sensor are positioned in the outdoor unit of the air conditioner. When the fresh air machine is positioned, the first detection device, the first humidity sensor and the control device are positioned on the indoor side, close to the fresh air machine, of the fresh air machine, and the second detection device and the second humidity sensor are positioned on the outdoor side, close to the fresh air machine, of the fresh air machine. The air conditioner carries out refrigeration or heating treatment on the indoor environment, and the fresh air machine is matched to introduce outdoor fresh air, so that the indoor air is prevented from being dry and stuffy, the outdoor fresh air with good air quality can be introduced to improve the indoor air quality, and the air conditioner is beneficial to human health. Meanwhile, when outdoor fresh air is introduced, the temperature of the air inlet is detected, the air conditioner heats indoors, the indoor temperature is high, the temperature of the air inlet is low, and when the difference value between the indoor temperature and the air inlet is large, the outdoor fresh air introduced from the air inlet is low in temperature, the air inlet is heated through the fresh air heater, and the fresh air is heated. The introduced outdoor fresh air is prevented from passing through a compressor of the air conditioner, and the air conditioner heats the outdoor fresh air, so that the energy consumption of the air conditioner can be reduced.
Referring to fig. 1, in an embodiment, the new fan system provided by the present invention includes a new fan, and the control method includes 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 system is suitable for introducing outdoor fresh air to purify and humidify 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 the first preset value and larger than the outdoor air index, and the outside and inside humidity is smaller than the second preset value and smaller than the outdoor humidity, judging whether the air inlet temperature of the fresh air fan is smaller than the 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 an air conditioner is in a heating state or a heating state of other fuel combustion in winter indoors, the temperature of the outdoor fresh air is low, and when the outdoor fresh air with low temperature is introduced, the indoor heating effect 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, whether the temperature is lower than the preset temperature or not is judged, and the preset temperature is set according to the human body comfortable temperature which can be received by most people, such as 28 ℃. And determining whether the air inlet needs to be heated or not according to the judgment result of the temperature of the air inlet and the preset temperature so as to ensure the comfort degree of the human body.
And step S30, when the temperature of the air inlet of the fresh air fan is lower than the preset temperature, starting a fresh air heater to heat the air inlet, and starting the fresh air fan to operate so as to introduce outdoor fresh air.
Furthermore, when the temperature of the air inlet of the fresh air fan is judged to be lower than the preset temperature, the temperature of the introduced external fresh air is lower, and the fresh air heater needs to be started to heat the air inlet. When the new fan is started, the introduced outdoor fresh air is heated and then enters the room to humidify and purify the indoor air, so that the temperature of the introduced outdoor fresh air is not greatly different from the original indoor air temperature, on one hand, the situation that the air conditioner is used indoors to heat is avoided, on the other hand, the introduced fresh air is prevented from influencing the comfort of the human body, and the heating energy consumption of the air conditioner is increased.
According to the control method of the fresh air fan 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 preset temperature; when the temperature of the air inlet of the fresh air fan is lower than the preset temperature, the fresh air heater is started to heat the air inlet, the fresh air fan is started to operate, and outdoor fresh air is introduced. The indoor air is humidified and purified by introducing the heated outdoor fresh air, so that the comfort level of a human body is improved, and the energy consumption is reduced.
Further, in another embodiment of the control method of the new air blower system of the present invention, the step of starting the new air heater to heat the air inlet and starting the new air blower to operate includes:
step S31, starting a heater of the fresh air fan to heat the air inlet, and detecting whether the temperature of the air inlet is higher than a preset temperature when the heating time reaches a first preset time;
and step S32, when the air inlet temperature is higher than the preset temperature, starting the fresh air fan to operate at the maximum rotating speed.
Understandably, in the initial heating stage, the temperature of the air inlet is lower, the outdoor fresh air introduced by the fresh air blower is lower in temperature, and the influence on the comfort level of the human body is also generated. Thus, the present embodiment sets the heating to a certain time, and then starts the new blower. The certain time is a preset first preset time, can be determined through multiple tests, and can be set differently according to different indoor environment temperatures. For example, the first preset duration of the indoor environment temperature of 20 ℃ and the first preset duration of the indoor environment temperature of 30 ℃ are shorter than the time consumed for increasing the outside fresh air to about 20 ℃ than the outside fresh air to about 30 ℃ under the same heating power, so that the first preset duration of the indoor environment temperature of 20 ℃ is set to be shorter than the first preset duration of the indoor environment temperature of 30 ℃. In addition, the heating operation cannot be performed for a long time, the heating temperature is too high due to the long-time heating, the comfort of human body is affected, and the energy consumption is increased. Therefore, when the heating time is first preset, whether the temperature of the air inlet is higher than the preset temperature or not is detected, the preset temperature is reached, the starting requirement of the fresh air fan is met, the fresh air fan is started to operate at the maximum rotating speed, the fresh air heater is turned off, and the heating time is prevented from being too long. 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. If the heating time reaches the first preset time, and the temperature of the air inlet is not higher than the preset temperature, the new fan is in a standby state and cannot be started.
Further, referring to fig. 2, on the basis of the first embodiment of the method for controlling a fresh air blower system of the present invention, a second embodiment of the method for controlling a fresh air blower 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 preset temperature includes:
and step S40, when the air inlet temperature of the fresh air fan is higher than the preset temperature, starting the fresh air fan to operate 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, and the temperature of the air inlet can be also larger than a preset temperature, namely, the difference value between the outdoor temperature and the indoor temperature is not large. Thereby when the temperature of air intake is greater than preset the temperature, need not heat the air intake, directly start new fan with the maximum rotational speed operation to the fastest speed introduces outdoor new trend, takes a breath to the room air, and with outdoor high quality, high humidity's new trend introduction indoor, purify the humidification to the room air, improve the room air quality fast, increase the degree of wetness.
Further, referring to fig. 3, on the basis of the second embodiment of the control method of the fresh air blower system of the present invention, a third embodiment of the control method of the fresh air blower system of the present invention is provided, and in the third embodiment, the step of starting the fresh air blower to operate at the maximum rotation speed includes:
step S50, when the time length of the fresh air fan running at the maximum rotating speed reaches a second preset time length, detecting whether the indoor air index is larger than a first preset value;
and step S60, 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 second preset time is set in the embodiment, and the second preset time can be preset according to the area of the indoor space and can also be customized by the 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 second preset time length, whether the indoor air index is larger than the 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, the running time length of the fresh air fan is insufficient, and therefore the fresh air fan is controlled to run at the maximum rotating speed continuously, outdoor fresh air is led in quickly, and humidification and purification are carried out. 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 handling system of the present invention, a fourth embodiment of the method for controlling a fresh air handling system of the present invention is provided, in the fourth embodiment, the fresh air handling system includes an air conditioner, and the step of detecting whether the indoor air index is greater than the first preset value includes:
step S70, when the indoor air index is less than or equal to the first preset value, detecting whether the indoor humidity is less than the second preset value;
and step S80, when the indoor humidity is less than the second preset value, reducing the current running frequency of the air conditioner.
Further, when the indoor air index is not larger than the first preset value, it is indicated that the indoor air quality reaches the standard after purification, and the pollutants in the indoor air index are not more than a few, it is further detected whether the indoor humidity reaches the standard, that is, whether the indoor humidity is smaller than the second preset value, when the indoor humidity is smaller than the second preset value, it is indicated that the indoor humidity is still too low, the indoor air is too dry, and the current operation frequency of the indoor air conditioner is controlled to be reduced. In the heating operation process of the air conditioner, the higher the operation frequency is, the faster the moisture taking speed is, so that the moisture taking speed is reduced by reducing the operation frequency, and the humidity of indoor air is ensured. And when the detected indoor humidity is not less than the second preset value, the indoor humidity meets the standard requirement, and the fresh air fan is controlled to be in standby state so as to save energy and prolong the service life of the air conditioner. In addition, after the current operation frequency of the air conditioner is reduced and operated, whether the indoor humidity is less than a second preset value needs to be further determined, and the steps are as follows:
step S90, detecting whether the indoor humidity is less than a second preset value;
and S100, when the indoor humidity is smaller than a second preset value, controlling the fresh air fan to continuously run at the maximum rotating speed.
After the current running frequency of the air conditioner is reduced and the speed of taking away the indoor environment moisture by the air conditioner is slowed down, whether the indoor humidity is smaller than a second preset value or not is further detected, namely whether the indoor humidity reaches the standard or not is detected. When indoor humidity is less than the second default at any time, indoor humidity is low when being low at any time, then control new fan with the maximum rotational speed operation to the higher air of outdoor humidity of introduction is to indoor, takes a breath the humidification to the room air, makes indoor air humidity be greater than or equal to the second default, satisfies human comfort level demand. And when detecting that the indoor humidity is not less than the second preset value, indicating that the indoor humidity meets the standard requirement, controlling the fresh air fan to stand by so as to save energy and prolong the service life of the air conditioner.
