Fig. 2 is a schematic flow chart of an energy-saving control method for an air conditioner host according to an embodiment of the present disclosure. As shown in fig. 2, the energy-saving control method for the air conditioner main unit comprises the following steps:
s201, obtaining target temperature and environmental parameter information preset by a user.
The preset target temperature is set by a user according to requirements, and the target temperature can be bought for a specific numerical value or can be a temperature range. The environmental parameter information at least comprises indoor air temperature, indoor air humidity, current outlet water temperature, return water temperature, the number of the people in the room and indoor area. In some embodiments, the air conditioner is installed in a building such as a school, a mall, a hospital, and the like, the environmental parameter information of the location where the air conditioner is located is obtained, for example, the environmental parameter information in each room is collected, the number of the rooms is 100, the point locations of the collected environmental parameter information may be determined to be 100, and the indoor air temperature and the indoor air humidity of each point location are obtained.
S202, preprocessing the environmental parameter information to obtain the corrected temperature.
And (4) preprocessing the environmental parameter information, namely cleaning the collected indoor air temperature and indoor air humidity. For example, the abnormal values such as the maximum value and the minimum value in the indoor temperature and humidity are screened out to be removed, the missing values are supplemented by selecting similar values, after data cleaning, the indoor air temperature is corrected and compensated based on the humidity correction theory, the specific compensation mode is to obtain the indoor air humidity and the indoor air temperature, the indoor air humidity is substituted into a formula to correct the indoor air temperature by using a humidity compensation coefficient, the humidity compensation coefficient can be between 0.5 and 1, a corrected temperature is obtained after calculation, and the obtained corrected temperature is the indoor air temperature under the condition that a user feels comfortable. As an example, the current indoor air temperature is obtained to be 26 ℃ and the indoor air humidity is 80%, the temperature is corrected, and the corrected compensation value is added to the current indoor air temperature to obtain the corrected temperature.
And S203, calculating by using a real-time comfort compensation model based on the target temperature and the corrected temperature to obtain a target outlet water temperature set value.
And comparing the corrected temperature obtained by calculating each point location with a target temperature preset by a user, wherein the target temperature set at each point location is different, and the obtained statistical comparison result is also different. And after comparison, determining the corresponding comfort level of each point position one by one according to a thermal comfort level model PMM-PPD.
Specifically, based on a thermal comfort model PMM-PPD, a PMV value and a PPD value can be obtained, the PMV value is an evaluation index for representing a human thermal response, the value represents an average value of the cold and hot feelings of most people in the same environment, and there are 7-level feelings: cold (-3), cold (-2), slightly cold (-1), neutral (0), slightly warm (1), warm (2), and hot (3). The PMV value is related to factors such as temperature, humidity, wind speed, average radiation temperature, clothing thermal resistance and human metabolism, and the PPD value represents the average number of votes which are uncomfortable to a hot environment, and reflects the comfort dissatisfaction of a user.
The corresponding relation between PPD and PMV is as follows:
PPD＝100-95exp(-0.03353PMV4-0.2179PMV2)
when the corrected temperature is equal to the target temperature and the PMV is equal to 0, the user feels most comfortable, the dissatisfaction is the lowest, and the PPD is about 5%, the comfort level corresponding to the point location is determined to be the most comfortable, when the corrected temperature is higher than the target temperature and the PMV value is higher than 0, the discomfort level is increased, the PPD value is increased, the maximum value is 100%, and the user comfort level corresponding to the point location is the heat bias; when the corrected temperature is lower than the target temperature and the PMV value is lower than 0, the discomfort degree is increased, the PPD value is increased to be 100% at most, and the comfort degree of the user corresponding to the point location is cold
Each point location corresponds to a comfort level, after the corrected temperatures of all the point locations are compared with the target temperature, the comfort level of each point location is counted to obtain a comfort satisfaction degree distribution graph, the calculated ratio of the partial cold and the partial hot of the comfort level is a comfort feedback result, the obtained conclusion is that the user feels the partial hot or the partial cold as a whole, the comfort feedback result is counted, and when the ratio of the partial cold or the partial hot in the comfort feedback result exceeds the preset threshold value in the comfort level model, the preset threshold value of the user is a numerical value preset by the user and can be adjusted according to actual conditions. When the comfort feedback result exceeds a preset threshold value in the comfort model, the outlet water temperature is determined to be required to be adjusted, and the outlet water temperature is adjusted up or down according to the comfort feedback result of the user, so that the aim of matching the user demand with the load rate of the air conditioner host is fulfilled. As an example, when the proportion of the heat bias in the user comfort feedback result is 85% and exceeds the preset maximum threshold value of 80%, the comfort feedback result and the target temperature are input into the real-time comfort compensation model for calculation to obtain a target outlet water temperature set value, and an adjustment mechanism is started to enable the user comfort to achieve the best effect.

In some embodiments, the target outlet water temperature setting value is adjusted according to actual conditions, such as season influence, and the outlet water temperature in winter is higher than the outlet water temperature in summer, which is not limited herein.
And S205, controlling the air conditioner host to adjust the load rate based on the control instruction.
