[0066] It should be noted that the above embodiments are calculated using dehumidification mode as an example. Similarly, it can be deduced that the adjustment method of humidification mode is the opposite of that of cooling mode. That is, when carbon emissions exceed the upper limit, the dew point temperature is adjusted to the set minimum value to reduce carbon emissions, and when carbon emissions are below the lower limit, the dew point temperature is adjusted to the maximum value to ensure humidification performance.

[0067] To correct the first target dew point temperature to obtain the second target dew point temperature, in an optional embodiment, step S203 further includes:

[0076] It should be noted that the above embodiments use dehumidification mode as an example for calculation. Similarly, it can be deduced that the adjustment method of humidification mode is the opposite of that of cooling mode. That is, when carbon emissions exceed the upper limit, the supply air humidity is adjusted to the set minimum value to reduce carbon emissions. When carbon emissions are below the lower limit, the supply air humidity is adjusted to the maximum value to ensure humidification performance.

[0077] To ensure that the indoor carbon dioxide content is within a preset range and to reduce the carbon emissions of the fresh air handling unit, in an optional embodiment, after controlling the operation of the fresh air handling unit according to the second target temperature and the second target dew point temperature or according to the second target temperature and the second target humidity, the method further includes:

[0078] Step S301: Obtain the target content, the first target frequency, and multiple preset content ranges. The target content is the indoor carbon dioxide content, and the first target frequency is the fan frequency of the fresh air unit.

[0079] Specifically, let the target content be C(τ), and the first target frequency be... Multiple carbon dioxide content thresholds C1, C2 and C3 are set to obtain carbon dioxide content ranges, namely the preset content ranges C(τ)<C3, C3≤C(τ)≤C2, C2<C(τ)≤C1 and C(τ)>C1.

[0080] Step S302: Determine the target content range based on the target content, wherein the target content range is the preset content range to which the target content belongs;

[0081] Specifically, based on the real-time monitoring of the target content, the range to which the target content belongs is determined to obtain the target content range.

[0082] Step S303: Determine the corresponding second target formula based on the above target content range, substitute the above first target frequency into the above second target formula to obtain the second target frequency, and use the above second target formula to update the above fan frequency of the above fresh air unit.

[0083] Specifically, according to the formula Substituting the aforementioned target content and the first target frequency into the formula, we obtain the second target frequency P. s,set , where P s,set,max and P s,set,min These are the upper and lower limits of the aforementioned fan frequency, respectively.

[0084] Step S304: Obtain the third target frequency, and control the operation of the fresh air handling unit according to the third target frequency until the third target frequency is equal to or less than the second target frequency. The third target frequency is the actual fan frequency of the fresh air handling unit.

[0085] Specifically, in order to reduce fan energy consumption and thus reduce carbon emissions from the fresh air handling unit, in one embodiment, this application sets the fan frequency to be reduced when indoor carbon dioxide levels are low, ensuring that the third target frequency is less than or equal to the second target frequency.

[0086] In order to control the supply air temperature and dew point temperature of the aforementioned fresh air handling unit, in an optional embodiment, step S204 includes:

[0087] Step S2041: When the second target temperature is greater than the third target temperature and the second target dew point temperature is greater than the third target dew point temperature, shut down the surface cooler and reheater in the fresh air unit, and adjust the preheater and humidity controller.

[0088] Specifically, when the actual supply air temperature is lower than the set supply air temperature and the actual dew point temperature is lower than the set dew point temperature, the actual supply air temperature can be increased by turning on the preheater. This can determine that the current indoor humidity is lower than the required humidity. By reducing the dehumidification performance of the humidity controller, the indoor humidity can be gradually increased to the set humidity.

[0089] Step S2042: When the second target temperature is greater than the third target temperature and the second target dew point temperature is less than or equal to the third target dew point temperature, shut down the preheater and the humidity controller, and adjust the surface cooler and the reheater.

[0090] Specifically, when the actual supply air temperature is lower than the set supply air temperature and the actual dew point temperature is greater than or equal to the set dew point temperature, the performance of the surface cooler is improved to condense the water vapor in the fresh air and increase the actual supply air temperature through the reheater, thereby reducing the actual dew point temperature indoors while increasing the actual supply air temperature.

[0091] Step S2043: When the second target temperature is less than or equal to the third target temperature and the second target dew point temperature is greater than the third target dew point temperature, shut down the preheater and the reheater, and adjust the surface cooler and the humidity controller.

[0092] Specifically, when the actual supply air temperature is higher than the set supply air temperature and the actual indoor dew point temperature is lower than the set dew point temperature, the actual supply air temperature is reduced by improving the performance of the surface cooler, and the indoor humidity is increased by reducing the dehumidification performance of the humidity controller.

[0093] In step S2044, when the second target temperature is less than or equal to the third target temperature and the second target dew point temperature is less than or equal to the third target dew point temperature, the preheater and the humidity controller are turned off, and the surface cooler and the reheater are adjusted.

[0094] Specifically, when the actual supply air temperature is higher than the set supply air temperature and the actual indoor dew point temperature is higher than the set dew point temperature, the performance of the surface cooler is improved to condense the water vapor in the fresh air to reduce the indoor humidity. Then, the reheater is used to heat the fresh air supply temperature to the set value at low performance to avoid the large temperature difference between the fresh air and the indoor environment from affecting the user's health.
