Referring to fig. 1, fig. 1 is a schematic flow chart of main steps of an air conditioner sleep heating method according to an embodiment of the present invention. As shown in fig. 1, the sleep heating method of the air conditioner in the embodiment of the invention mainly includes the following steps S101 to S102.
Step S101: and receiving a sleep heating instruction.
Step S102: after receiving the sleep heating instruction, controlling the air conditioner to sequentially enter a temperature control stage and a temperature and humidity double control stage to execute corresponding sleep heating operation.
1. 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-humidity double control stage after the heating time reaches the first control time. The temperature control stage is the first stage that the air conditioner enters after starting the sleep heating, and the heating time is relatively short at this moment, and the air humidity of the indoor space is not reduced much yet, so that humidification control is not needed in the temperature control stage. Meanwhile, in the temperature control stage, the air conditioner is controlled to heat according to the heating temperature set by the user, so that the heating requirement of the user can be met, and the experience of the user is improved.
In one implementation manner of the embodiment of the present invention, the air temperature of the indoor space may be negatively feedback-controlled by taking the heating temperature set by the user as a target amount, taking the actual air temperature of the indoor space as a control amount, and taking the 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) T Based on the proportionality coefficient K T And performing negative feedback proportional control on the air temperature.
(T set -T a2 )×K T ＝Q T (1)
The meaning of each parameter in the formula (1) is as follows:
T set indicating the heating temperature set by the user, T a2 The method is characterized in that under the condition that the initial air temperature of the indoor space is a preset value, the air conditioner is controlled to heat according to the heating temperature set by a user, when the heating time length reaches the actual air temperature of the indoor space after the preset time length, Q T And means for controlling the electric power (theoretical heating power) consumed when the air conditioner increases the air temperature of the indoor space from the initial air temperature to the heating temperature set by the user in the same heating period when the initial air temperature of the indoor space is the preset value.
2. Temperature and humidity double control stage
In the temperature and humidity double control stage, the sleeping heating operation comprises the following steps: and (3) modulating the heating temperature downwards, controlling the air conditioner to heat according to the heating temperature after the temperature is modulated downwards, and simultaneously controlling the air extractor to extract cold air in the outdoor space to the indoor space according to the set value of the humidity so as to humidify the indoor space. In cold weather, the air humidity of the outdoor space is always higher than that of the indoor space, and the air humidity of the indoor space can be increased by pumping the cold air of the outdoor space into the indoor space. The temperature and humidity double control stage is the second stage which is entered after the air conditioner starts to sleep and heat, and the heating time is longer at this time, and the air humidity of the indoor space is reduced greatly, so that the humidification control is needed in the temperature and humidity double control stage. In addition, if the air conditioner is continuously controlled to heat according to the heating temperature set by the user, the dryness-heat sensation of the user can be obviously increased, and the difficulty of humidification control can be increased. Therefore, when heating is performed in the temperature-humidity double-control stage, the heating temperature set by a user can be adjusted downwards, and the air conditioner is controlled to perform heating 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, the specific value of the first control duration in the temperature control stage can be flexibly set by a person skilled in the art according to actual requirements, for example, the first control duration can be 1 hour.
In one implementation manner of the embodiment of the present invention, the heating temperature set by the user may be set as the first target amount, the humidity set value may be set as the first target amount, the actual air temperature of the indoor space may be set as the first control amount, the actual air humidity of the indoor space may be set as the second control amount, the deviation between the heating temperature set by the user and the actual air temperature of the indoor space may be set as the first feedback amount, and the deviation between the humidity set value and the actual air humidity of the indoor space may be set as the 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 implementationsIn the embodiment, the proportionality coefficient K of the temperature control can be calculated by the formula (1) T Scaling factor K according to temperature control T And performing 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) H Based on the proportionality coefficient K H And performing negative feedback proportional control on the air humidity.
(H set -H a2 )×K H ＝Q H (2)
The meaning of each parameter in the formula (2) is as follows:
H set indicating the humidity set value, H a2 The method comprises the steps of controlling an air extractor to humidify according to a humidity set value under the condition that initial air humidity of an indoor space is a preset value, and when humidification duration reaches the actual air humidity of the indoor space after the preset duration, controlling the air extractor to humidify according to the humidity set value, wherein Q H The electric power (theoretical humidifying 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 humidifying period when the initial air humidity of the indoor space is a preset value is expressed.
The temperature control in the temperature-humidity double control stage is further described below.
In cold weather, although the air humidity of the outdoor space is higher than the air humidity of the indoor space, the air temperature of the outdoor space is often lower than the air temperature of the indoor space, the air temperature of the indoor space is reduced after the cold air of the outdoor space is extracted into the indoor space, and in order to enable the air temperature of the indoor space to reach the down-regulated heating temperature after the air conditioner heats according to the down-regulated heating temperature, the down-regulated heating temperature can be subjected to temperature compensation (the heating temperature is increased), and then the air conditioner is controlled to heat according to the compensated heating temperature. Referring to fig. 2, in one implementation of the embodiment of the present invention, the temperature compensation of the heating temperature after the down-regulation may be performed through the following steps S201 to S203.
Step S201: and estimating the temperature falling speed of the indoor space in the process of extracting cold air in the outdoor space to the indoor space to humidify the indoor space by controlling the air extractor according to the humidity set value under the condition of not heating.
Step S202: and calculating a temperature drop value of the indoor space after the humidifying duration reaches the second control duration according to the temperature drop speed, and taking the temperature drop value as a temperature compensation value.
Specifically, according to the humidity decreasing speed, calculating a temperature decreasing value of the indoor space after a humidifying duration for controlling the air extractor to extract cold air of the outdoor space to the indoor space to humidify the indoor space according to the humidity set value under the condition that heating is not performed reaches a second control duration, wherein the temperature decreasing value is taken as a temperature compensating value, and the temperature decreasing value is the product of the temperature decreasing speed and the second control duration.
Step S203: and taking the sum of the down-regulated heating temperature and the temperature compensation value as a new heating temperature, wherein the new heating temperature is the temperature after temperature compensation. In the temperature-humidity double control stage, the air conditioner is controlled to heat according to the new heating temperature.

Assume that the spatial volume of the room test space S is 40M 3 The air temperature is 30 ℃, the humidity value is 60%, and the air extraction rate is 3M 3 And/min. The air extractor is controlled to adopt 3M according to the humidity value of 60 percent 3 The air extraction rate per min is used for extracting cold air in the outdoor space into the indoor test space S for humidification, the falling speed of the air temperature in the indoor test space S is tested in the humidification process, the test result is used as the indoor test space S, the air temperature is 30 ℃, the humidity value is 60%, and the air extraction rate is 3M 3 Test space temperature drop rate under the condition of/min ".
