First, temperature control stage
In the temperature control stage, the sleep heating operation includes: and controlling the air conditioner to heat according to the heating temperature set by the user, and controlling the air conditioner to enter a temperature and humidity double-control stage after the heating time reaches a first control time. The temperature control stage is the first stage of the air conditioner after starting sleep and heating, and at the moment, the heating time is short, and the air humidity of the indoor space is not reduced a lot, so that the humidification control is not needed in the temperature control stage. Meanwhile, the air conditioner is controlled to heat according to the heating temperature set by the user in the temperature control stage, so that the heating requirement of the user can be met, and the experience of the user is improved.
In one embodiment of the present invention, the air temperature of the indoor space may be negatively feedback controlled using the heating temperature set by the user as a target amount, the actual air temperature of the indoor space as a control amount, and a deviation between the heating temperature set by the user and the actual air temperature of the indoor space as a feedback amount. For example, in some embodiments the scaling factor K may be calculated by the following equation (1)TBased on the proportional coefficient KTAnd carrying out negative feedback proportional control on the air temperature.
(Tset-Ta2)×KT＝QT (1)
The meaning of each parameter in formula (1) is as follows:

The air humidity of the outdoor space is often higher than that of the indoor space in cold weather, the cold air of the outdoor space is extracted to the indoor space to increase the air humidity of the indoor space, and the humidification is performed without using water, so that the safety accident caused by water shortage or water leakage can be avoided. The temperature and humidity double control stage is the second stage of the air conditioner after starting sleep to heat, and the heating time is long and the air humidity in the indoor space is reduced greatly. In addition, if the air conditioner is continuously controlled to perform heating according to the heating temperature set by the user, not only the dryness-heat sensation of the user is remarkably increased, but also the difficulty of humidification control is increased. Therefore, the heating temperature set by the user can be adjusted downwards when the temperature and humidity dual-control stage heats, and the air conditioner is controlled to heat according to the adjusted heating temperature, so that the experience of the user is further improved.
It should be noted that the heating temperature after the down-regulation is not lower than the preset optimal sleep temperature. In addition, a person skilled in the art can flexibly set a specific value of the first control time period in the temperature control stage according to actual requirements, for example, the first control time period may be 1 hour.
In one embodiment of the present invention, the heating temperature set by the user may be set as a first target amount, the humidity setting value may be set as a first target amount, the actual air temperature of the indoor space may be set as a first control amount, the actual air humidity of the indoor space may be set as a second control amount, a deviation between the heating temperature set by the user and the actual air temperature of the indoor space may be set as a first feedback amount, and a deviation between the humidity setting value and the actual air humidity of the indoor space may be set as a second feedback amount. And performing negative feedback control on the air temperature of the indoor space according to the first target amount, the first control amount and the first feedback amount, and performing negative feedback control on the air humidity of the indoor space according to the second target amount, the second control amount and the second feedback amount.
For example, in some embodiments, the temperature-controlled proportionality coefficient K may be calculated by equation (1) aboveTProportional coefficient K controlled according to temperatureTAnd carrying out negative feedback proportional control on the air temperature. Meanwhile, the proportionality coefficient K of humidity control can also be calculated by the following formula (2)HBased on the proportional coefficient KHAnd carrying out negative feedback proportional control on the air humidity.
(Hset-Ha2)×KH＝QH (2)
The meaning of each parameter in the formula (2) is as follows:
Hsetindicates the humidity set point, Ha2Indicating that the air extractor is controlled to humidify according to a humidity set value under the condition that the initial air humidity of the indoor space is a preset value, and when the humidifying time reaches a preset time, the actual air humidity of the indoor space, QHWhich represents the electric power (theoretical humidification power) consumed by the air extractor when the air extractor is controlled to raise the air humidity of the indoor space from the initial air humidity to the humidity set value within the same humidification period, in the case where the initial air humidity of the indoor space is a preset value.
The temperature control in the temperature and humidity dual control stage is further explained below.
Although the air humidity of the outdoor space is higher than the air humidity of the indoor space in cold weather, the air temperature of the outdoor space is often lower than the air temperature of the indoor space, and the air temperature of the indoor space is reduced after the cold air of the outdoor space is extracted into the indoor space. Referring to fig. 2, in an embodiment of the present invention, the temperature compensation of the down-regulated heating temperature may be performed through the following steps S201 to S203.

Step S202: and calculating the temperature drop value of the indoor space after the humidifying time reaches the second control time according to the temperature drop speed, and taking the temperature drop value as a temperature compensation value.
Specifically, according to the humidity reduction speed, after the humidification time period for humidifying the indoor space by controlling the air extracting device to extract cold air of the outdoor space to the indoor space according to the humidity set value under the condition of not heating is calculated to reach a second control time period, the temperature reduction value of the indoor space is used as a temperature compensation value, and the temperature reduction value is the product of the temperature reduction speed and the second control time period.
Step S203: and taking the sum of the heating temperature after the down regulation and the temperature compensation value as a new heating temperature, wherein the new heating temperature is the temperature after the temperature compensation. And in the temperature and humidity dual-control stage, controlling the air conditioner to heat according to the new heating temperature.
Referring to fig. 3, in one embodiment of the above step S201, the temperature decrease rate can be estimated through the following steps S301 to S303.
