If the temperature of the fresh air is lower than the preset first temperature threshold value, the outdoor temperature is low, the effect of removing indoor harmful gas is poor, in order to ensure that the effect of removing indoor harmful gas is good, the indoor temperature needs to be increased, since the outdoor temperature is low, in order to rapidly increase the indoor temperature, the temperature exchange between the outdoor and indoor needs to be reduced as much as possible, therefore, the fresh air valve 6 and the exhaust valve 7 can be closed to stop sucking the outdoor air, then the air mixing valve 8 is opened to communicate the fresh air channel and the exhaust air channel of the fresh air equipment, then the blower 1 and the exhaust fan 2 are started, and the heating device 4 is adjusted to be in heating operation, so that the indoor air can rapidly flow in the fresh air equipment in a circulating way, and the indoor air is heated by the heating device 4, so that the indoor temperature is quickly increased, and the volatilization speed of the indoor harmful gas is accelerated. The heating device 4 is started to perform heating operation, besides starting a heat pump in the heating device 4, the operation frequency of a compressor can be increased or the opening degree of an expansion valve can be reduced, so that the condensation temperature of the heating device is increased; when the heating device 4 is turned off, the heat pump in the heating device 4 is controlled to stop, and besides, the condensing temperature of the heating device can be reduced by reducing the operation frequency of the compressor or increasing the opening degree of the expansion valve.
In a specific implementation, the heating device 4 may be a heat exchanger, for example: water heat exchanger or heat pump heat exchanger, also can be the combination of water heat exchanger and heat pump heat exchanger, when heating device was for water heat exchanger, the hot water that its used can derive from underfloor heating system or life hot water, and new trend equipment this moment can not need to set up outer machine.
In actual use, if the indoor temperature is too low, the indoor temperature is difficult to be rapidly heated to an ideal temperature only through the heating device, therefore, the heating device can be further connected with the floor heating system, when the indoor temperature is detected to be smaller than a preset third temperature threshold value, the floor heating system is controlled to be started, the floor heating system is used for auxiliary heating, the preset third temperature threshold value is smaller than the preset second temperature threshold value, and the value range can be 15-25 ℃.
Step S30: when the concentration of indoor harmful gas meets the preset harm-removing condition, the fresh air valve and the exhaust valve are opened, the air mixing valve is closed, and the air feeder and the exhaust fan are started.
It should be noted that, along with the improvement of indoor temperature, indoor harmful gas's volatilization velocity can accelerate, this in-process, indoor harmful gas's concentration can constantly promote, if indoor harmful gas concentration satisfies the preset condition of removing the evil, then it has reached the except that the harmful standard that sets up in advance to show indoor harmful gas concentration, then can open fresh air valve 6 and exhaust valve 7 this moment, and close air mixing valve 8, thereby make the operation of new trend equipment extrinsic cycle mode, take a breath with the outside, thereby take a breath through extrinsic cycle with indoor harmful gas and get rid of indoorly.
In actual use, can gather indoor harmful gas concentration through the harmful gas sensor 9 that sets up in the exhaust passage, when indoor harmful gas concentration is greater than or equal to and predetermines the concentration threshold value, judge that indoor harmful gas concentration satisfies and predetermine the condition of removing the evil. For example: taking formaldehyde as an example, a formaldehyde sensor is arranged in the exhaust channel, indoor formaldehyde concentration is collected through the formaldehyde sensor, and when the indoor formaldehyde concentration is greater than or equal to a preset concentration threshold value, the indoor formaldehyde concentration is judged to meet a preset pest eliminating condition.
It can be understood that, in the harmful gas elimination process, in order to guarantee the volatilization speed of the indoor harmful gas, the indoor temperature can be continuously collected, and the running state of the heating device is adjusted according to the indoor temperature, so that the reduction of the indoor temperature in the harmful gas elimination process is avoided, and the volatilization speed of the indoor harmful gas is reduced.
Further, in order to accurately determine whether pest elimination is required, before step S30, the method may further include:
adjusting the operation state of the heating device according to the indoor temperature; and
and when the indoor harmful gas concentration is greater than or equal to the third concentration value and the duration is greater than or equal to the third duration, judging that the indoor harmful gas concentration meets the preset harm-removing condition.
In practical use, in the process of improving the indoor temperature by using the heating device, the indoor temperature can be collected by the exhaust air temperature sensor arranged in the exhaust air channel, and the operation state of the heating device 4 can be adjusted according to the indoor temperature. For example: when the indoor temperature is higher than a preset first temperature threshold value, judging that the indoor temperature is high enough, and stopping the operation of the heating device; when the indoor temperature is lower than a preset second temperature threshold value, judging that the indoor temperature is too low, enabling the heating device to operate in a heating mode, and increasing the heating temperature of the heating device; and when the indoor temperature is greater than or equal to a preset second temperature threshold value but less than or equal to a preset first temperature threshold value, judging that the current heating temperature of the heating device is enough, and maintaining the heating device to stably operate at the current heating temperature, wherein the preset second temperature threshold value is less than the preset first temperature threshold value.
It should be noted that the third concentration value may be a preset concentration threshold value that needs to be eliminated by harmful gas, and the value range may be 0 to 10mg/m3If the indoor harmful gas concentration is greater than or equal to the third concentration value, it indicates that the harmful gas is required to be discharged, however, in the operation process of the harmful gas sensor, the detected data is inaccurate or fluctuates due to the influence of various factors, and the misjudgment phenomenon may occur only by judging the indoor harmful gas concentration detected in a moment, in order to improve the judgment accuracy, when judging whether the preset harm removing condition is met, the judgment can be carried out in combination with the duration, wherein the third duration value range can be 0-8h, for example: and when the detected indoor harmful gas concentration is greater than or equal to the third concentration value within 30 seconds, judging that the preset harm removing condition is met.
This embodiment is through being low at the new trend temperature, adjust the valve of new trend equipment earlier when outdoor temperature is low promptly, avoid carrying out the air exchange with the external world, carry out rapid heating to indoor, accelerate indoor harmful gas to volatilize, last control room harmful gas concentration in the heating process, when indoor harmful gas concentration satisfies the preset condition of removing harm, adjust the valve on-off state of new trend equipment, make new trend equipment outer loop mode operation, take a breath through the extrinsic cycle and get rid of indoor harmful gas, make outdoor temperature low still can the indoor harmful gas of efficient exclusion.
Referring to fig. 5, fig. 5 is a flowchart illustrating a control method for a fresh air device according to a second embodiment of the present invention.
Based on the first embodiment, the method for controlling the fresh air device in this embodiment further includes, after the step S30:
step S40: and monitoring the indoor temperature and the indoor harmful gas concentration in real time.
It should be noted that, in the process of removing indoor harmful gas by external circulation ventilation, the concentration of indoor harmful gas gradually changes along with the exchange with the outside air, and since the volatilization speed of harmful gas is reduced when the indoor temperature is low, the concentration of indoor harmful gas may be low at this time, when determining whether to complete the removal of harmful gas, it is not accurate to determine only by the concentration of indoor harmful gas, and it is necessary to determine by combining the indoor temperature and the concentration of indoor harmful gas together, and therefore, it is necessary to detect the indoor temperature and the concentration of indoor harmful gas in real time.
In practical use, the indoor temperature can be periodically collected by the exhaust air temperature sensor 10, and the indoor harmful gas concentration can be collected by the harmful gas sensor 9, for example: with 1 second as the cycle, the indoor temperature is periodically collected through the exhaust temperature sensor, and the indoor harmful gas concentration is collected through the harmful gas sensor.
Further, in order to avoid unnecessary power loss, after step S40, the method may further include:
and if the indoor temperature and the indoor harmful gas concentration are detected not to meet the preset exit condition but meet the secondary harm removal condition, returning to the step of acquiring the environment temperature when the fresh air equipment operates in the harm removal mode.
It should be noted that the outdoor temperature and the indoor temperature may change with time, if the indoor temperature and the indoor harmful gas concentration do not satisfy the preset exit condition but satisfy the condition of removing harmful gas again after removing harmful gas for a period of time, it indicates that the harmful gas still needs to be removed, but the outdoor temperature may have changed at this time, the effect of removing harmful gas may not be ideal if the operation is continued in the current mode, and the operation state of the fresh air device may also need to be adjusted, so that the operation may be returned to the step S10, and the determination may be performed again according to the fresh air temperature, so as to determine how the fresh air device should operate, thereby avoiding unnecessary power loss.
In actual use, in order to accurately judge whether to perform secondary aldehyde removal, when it is detected that the indoor harmful gas concentration is greater than or equal to the first concentration value, but is less than the second concentration value and the duration is greater than or equal to the second duration, it is determined that the detected indoor temperature and the indoor harmful gas concentration do not meet the preset exit condition, but meet the secondary aldehyde removal condition. Specifically, at a certain time point within the fourth time period of step S30, it is detected that the indoor harmful gas concentration is greater than or equal to the first concentration value but less than the second concentration value, and the duration is greater than or equal to the second time period, it is determined that the detected indoor temperature and indoor harmful gas concentration do not satisfy the preset exit condition but satisfy the condition of removing harmful gas again. In other words, from the time when step S30 is executed, the time is counted until the cumulative duration when the indoor harmful gas concentration is detected to be greater than or equal to the first concentration value but less than the second concentration value, and if the cumulative duration is less than the fourth duration, and the harmful gas concentration is greater than or equal to the first concentration value but less than the second concentration value reaches the second duration, it is determined that the indoor temperature and the indoor harmful gas concentration do not satisfy the preset exit condition, but satisfy the condition of removing harmful gases again; on the contrary, if the indoor harmful gas concentration is greater than or equal to the second concentration value after the time is counted from the step S30 to the fourth time, it is determined that the condition for continuously removing harmful gas is satisfied, and at this time, the step S30 is continuously executed and the time is counted again; or, if the accumulated time length is less than the fourth time length, the harmful gas concentration is greater than or equal to the first concentration value, but the duration time length less than the second concentration value is less than the second time length, it is determined that the condition of continuing to remove harmful gases is met, and at this time, the step S30 is continuously executed and the timer is restarted.
It should be noted that the second concentration value may be preset by a manager of the fresh air device, the second concentration value is smaller than the third concentration value and larger than the first concentration value, the detected data may be inaccurate or fluctuate due to various factors during the operation of the harmful gas sensor 9, and if the preset exit condition is determined to be met only according to a certain instantaneous value, a misjudgment may occur.
Step S50: and controlling the fresh air equipment to exit the pest eliminating mode when detecting that the indoor temperature and the indoor harmful gas concentration meet preset exit conditions.
It should be noted that if the indoor temperature and the indoor harmful gas concentration meet the preset exit condition, it indicates that the indoor harmful gas concentration has reached the human health standard after the harmful gas is removed, and therefore, the fresh air device can be controlled to exit the harm removal mode.
In actual use, the fresh air device may continue to operate in the normal mode after exiting the pest elimination mode, or may stop operating after exiting the pest elimination mode, which is not limited in this embodiment.
Further, in order to accurately determine whether the pest elimination mode can be exited, before step S50, the method may further include:
if the indoor temperature is greater than or equal to the preset first temperature threshold value, the indoor harmful gas concentration is smaller than a first concentration value, and the duration is greater than or equal to a first duration, it is determined that the indoor temperature and the indoor harmful gas concentration meet a preset exit condition.
It should be noted that the first concentration value may be preset by a manager of the fresh air device, the first concentration value is smaller than the third concentration value, if the indoor temperature is greater than or equal to the preset first temperature threshold value, and the indoor harmful gas concentration is smaller than the first concentration value, it indicates that the indoor harmful gas concentration is still lower than the first concentration value at the temperature where the volatilization speed of the harmful gas is fast, and it may indicate that the indoor harmful gas concentration has reached the human health standard after the harmful gas is removed this time, however, the exhaust temperature sensor and the harmful gas sensor may cause inaccurate or fluctuating data due to various factors in the operation process, and if it is determined that the preset exit condition is met only according to a certain instantaneous value, an erroneous determination may occur, and therefore, when it is determined that the preset exit condition is met, the determination may be performed in combination with the duration, in order to accurately determine whether the preset exit condition is met, at a certain time point within a fourth time range of the step S30, it is detected that the indoor temperature is greater than or equal to a preset first temperature threshold value and the indoor harmful gas concentration is less than a first concentration value, and the first time duration continues from the time point, and then it is determined that the preset exit condition is met, in other words, from the step S30, the time is started until the accumulated time duration when the indoor temperature is greater than or equal to the preset first temperature threshold value is detected, and if the accumulated time duration is less than the fourth time duration and the duration when the indoor harmful gas concentration is less than the first concentration value reaches the first time duration, it is determined that the preset exit condition is met; on the contrary, if the indoor harmful gas concentration is greater than or equal to the first concentration value from the time of executing the step S30 to the fourth time, it is determined that the preset exit condition is not satisfied; or if the accumulated time length is less than the fourth time length and the duration time length of the indoor harmful gas concentration less than the first concentration value is less than the first time length, judging that the preset exit condition is not met; wherein, the value range of first duration can be 0-8h, and the fourth duration scope can be set up according to actual need, for example: after step S30 is executed, it is detected that the indoor harmful gas concentration is less than the first concentration value, and the time is continuously counted for 10 minutes, and when the indoor temperature is greater than or equal to the preset first temperature threshold value in this ten minutes and the indoor harmful gas concentration is less than the first concentration value, it is determined that the preset exit condition is satisfied.
This embodiment is through implementing control room interior temperature and indoor harmful gas concentration getting rid of harmful gas's in-process, releases fast when indoor temperature and indoor harmful gas concentration have satisfied predetermineeing the condition of withdrawing from, has guaranteed also to have avoided continuing to operate the mode of removing harm after indoor harmful gas concentration reaches the health standard when can normally getting rid of indoor harmful gas, has avoided unnecessary wasting of resources.

step S20': if the fresh air temperature is greater than or equal to a preset first temperature threshold value, the fresh air valve and the exhaust valve are opened, the air mixing valve is closed, and the air feeder and the exhaust fan are started.
It can be understood that if the new trend temperature is greater than or equal to predetermine first temperature threshold value, then it is higher to indicate this moment outdoor temperature, can not reduce indoor temperature when carrying out the air exchange with the outside, can not reduce indoor harmful gas's volatilization speed promptly, therefore, need not to heat indoorly, can directly discharge indoor harmful gas, consequently, can open new trend valve 6 and exhaust valve 7, close air mixing valve 8, start forced draught blower 1 and exhaust fan 2, make the operation of new trend equipment outer loop mode, carry out the air exchange with the outside, thereby discharge indoor harmful gas.
Step S30': and monitoring the indoor temperature and the indoor harmful gas concentration in real time.
It should be noted that, in the process of removing indoor harmful gas by external circulation ventilation, the concentration of indoor harmful gas gradually changes along with the exchange with the outside air, and since the volatilization speed of harmful gas is reduced when the indoor temperature is low, the concentration of indoor harmful gas may be low at this time, when determining whether to complete the removal of harmful gas, it is not accurate to determine only by the concentration of indoor harmful gas, and it is necessary to determine by combining the indoor temperature and the concentration of indoor harmful gas together, and therefore, it is necessary to detect the indoor temperature and the concentration of indoor harmful gas in real time.
In practical use, the indoor temperature can be periodically collected by the exhaust air temperature sensor 11, and the indoor harmful gas concentration can be collected by the harmful gas sensor 9, for example: with the period of 1 second as a period, the indoor temperature is periodically collected through the exhaust air temperature sensor 11, and the indoor harmful gas concentration is collected through the harmful gas sensor 9.
Step S40': and controlling the fresh air equipment to exit the pest eliminating mode when detecting that the indoor temperature and the indoor harmful gas concentration meet preset exit conditions.
It should be noted that if the indoor temperature and the indoor harmful gas concentration satisfy the preset exit condition, it indicates that the harmful gas removal has reached the preset removal target, and therefore, the fresh air device can be controlled to exit the harm removal mode.
It can be understood that, in the operation process, if the indoor temperature and the indoor harmful gas concentration do not satisfy the preset exit condition, the operation process may further return to the step S10, detect the fresh air temperature, and determine whether the operation state of the fresh air device needs to be adjusted.
This embodiment is through detecting the new trend temperature, when the new trend temperature is greater than or equal to predetermine first temperature threshold value, direct control new trend equipment when outdoor temperature is higher promptly moves with the extrinsic cycle mode, carry out the air exchange with outdoor, discharge indoor harmful gas, avoided heating when outdoor temperature is higher, thereby the wasting of resources has been reduced, and still can detect the new trend temperature at the in-process of discharging harmful gas, judge the change of outdoor temperature according to new trend text section, thereby confirm whether need adjust the running state of new trend equipment, under the circumstances that has reduced the wasting of resources, but the indoor harmful gas of efficient discharge still is guaranteed.
In addition, an embodiment of the present invention further provides a storage medium, where a fresh air device control program is stored on the storage medium, and the steps of the fresh air device control method described above are implemented when the fresh air device control program is executed by a processor.
Referring to fig. 7, fig. 7 is a block diagram of a first embodiment of the fresh air device control apparatus according to the present invention.
As shown in fig. 7, a fresh air device control apparatus provided in an embodiment of the present invention includes:

If the temperature of the fresh air is lower than the preset first temperature threshold value, the outdoor temperature is low, the effect of removing indoor harmful gas is poor, in order to ensure that the effect of removing indoor harmful gas is good, the indoor temperature needs to be increased, since the outdoor temperature is low, in order to rapidly increase the indoor temperature, the temperature exchange between the outdoor and indoor needs to be reduced as much as possible, therefore, the fresh air valve 6 and the exhaust valve 7 can be closed to stop sucking the outdoor air, then the air mixing valve 8 is opened to communicate the fresh air channel of the fresh air equipment with the exhaust channel, then the blower 1 and the exhaust fan 2 are started, and the heating device 4 is adjusted to be in heating operation, so that the indoor air can rapidly flow in the fresh air equipment in a circulating way, and the indoor air is heated by the heating device, so that the indoor temperature is quickly increased, and the volatilization speed of the indoor harmful gas is accelerated. The heating device 4 is started to perform heating operation, besides starting a heat pump in the heating device, the operation frequency of a compressor can be increased or the opening degree of an expansion valve can be reduced, so that the condensation temperature of the heating device is increased; when the heating device 4 is turned off, the heat pump in the heating device is controlled to stop, and the condensing temperature of the heating device can be reduced by reducing the operation frequency of the compressor or increasing the opening degree of the expansion valve.
In a specific implementation, the heating device 4 may be a heat exchanger, for example: water heat exchanger or heat pump heat exchanger, also can be the combination of water heat exchanger and heat pump heat exchanger, when heating device was for water heat exchanger, the hot water that its used can derive from underfloor heating system or life hot water, and new trend equipment this moment can not need to set up outer machine.

In actual use, if the indoor temperature is too low, the indoor temperature is difficult to be rapidly heated to the ideal temperature only through the heating device 4, therefore, the heating device can be further connected with the floor heating system, when the indoor temperature is detected to be smaller than a preset third temperature threshold value, the floor heating system is controlled to be started, the floor heating system is used for auxiliary heating, the preset third temperature threshold value is smaller than the preset second temperature threshold value, and the value range can be 15-25 ℃.
And the state adjusting module 300 is used for opening the fresh air valve and the exhaust valve, closing the air mixing valve and starting the air feeder and the exhaust fan when the concentration of indoor harmful gas meets the preset harm removing condition.
