Step S1012: the actual concentration of fragrance particles in the room is detected. In particular, the particle concentration can be detected by a commonly used particle concentration detection device.
Step S1013: a standard room volume is determined based on the actual fragrance particle concentration. In one embodiment, determining the standard room volume based on the actual fragrance particle concentration comprises: determining the difference between the actual concentration of the fragrance particles and the concentration of each standard fragrance particle in the database; obtaining the standard fragrance particle concentration corresponding to the minimum value of the difference values; and obtaining the standard room volume based on the standard fragrance particle concentration corresponding to the minimum value of the difference.

The room volume is calculated through the actual concentration of the fragrance particles, and the accuracy of the calculation of the room volume is improved.
In one embodiment, the database stores a plurality of standard fragrance particle concentration-to-room volume correspondences, wherein the plurality of standard fragrance particle concentration-to-room volume correspondences are obtained through experimental tests in advance. Specifically, in the process of test, firstly, in the closed standard space, the device is arrangedIs arranged at 10m3、20m3、30m3、40m3And 50m3These five standard room volumes. Specifically, as shown in fig. 2, after the fragrance function is started, the fresh air function is started, and the fresh air function takes 3m3The ventilation volume of/min continuously works for 20min, the fresh air function is closed after the fresh air function works for 20min, meanwhile, the air-conditioning compressor is closed, the inner fan works in a powerful state, the air deflector freely swings air and continuously works for 5min, and the fragrance particles in the space are fully mixed.

Step S102: the temperature difference is determined based on an operation mode of the air conditioner. In one embodiment, the operation mode of the air conditioner includes a heating mode and a cooling mode; determining the temperature difference based on the operation mode of the air conditioner includes: setting an initial temperature corresponding to the operation mode, and setting the wind speed of the indoor fan to be a high wind speed; after the indoor temperature reaches the initial temperature, closing the air conditioner, and acquiring the current temperature after the preset time; and obtaining a temperature difference based on the initial temperature and the current temperature, and specifically taking the difference value between the initial temperature and the current temperature as the temperature difference. The temperature difference is determined through the initial temperature and the current temperature, so that basic support is provided for calculating the loss heat according to the temperature difference.
Step S103: based on the standard room volume and the temperature difference, the heat lost by the room per unit time is determined. In one embodiment, the heat loss per unit time of the room is determined based on the standard room volume and the temperature difference by the calculation formula:
Q＝J|T0-T1|A/30 (1)
in the above formula, Q is the heat loss of the room in unit time, J is the coefficient of variation of heat in unit volume, and T0Is the initial temperature, T1For the current temperature, a is the standard room volume.
Step S104: and determining the current rotating speed of the indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve based on the lost heat. In one embodiment, determining the current indoor fan rotation speed, the compressor frequency and the solenoid valve opening and closing angle based on the heat loss comprises: and determining the current rotating speed of the indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve based on the corresponding relation between the lost heat and the rotating speed of the preset indoor fan, the frequency of the preset compressor and the opening and closing angle of the preset electromagnetic valve. The rotating speed of the indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve are preset in the step and are obtained through measurement.
Step S105: the air conditioner is accurately controlled based on the rotating speed of the current indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve.
Based on the steps S101 to S105, the lost heat of the room in unit time is determined through the standard room volume and the temperature difference, the current rotating speed of the indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve are determined based on the lost heat, and finally the air conditioner is accurately controlled based on the current rotating speed of the indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve, so that the air conditioner is accurately controlled according to the room volume, and the user requirements are met.
Furthermore, the lost heat and the corresponding relation among the rotating speed of presetting the indoor fan, the frequency of presetting the compressor and the opening and closing angle of presetting the solenoid valve in this application are obtained through realizing the measurement in advance, specifically the air conditioner is under corresponding operating mode, through the rotating speed of presetting the indoor fan under the corresponding temperature of measurement, the frequency of presetting the compressor and the opening and closing angle of presetting the solenoid valve to calculate the refrigerating output or the heating output of air conditioner, wherein, the computational formula of refrigerating output and/or heating output is as follows:
in the above formula, QiK is a heat coefficient, V is a preset rotating speed of an indoor fan, f is a preset frequency of a compressor,
the opening and closing angle of the electromagnetic valve is preset.
Illustratively, taking a rated temperature of 23 degrees as an example, the rotation speed of the indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve can be obtained through measurement, and then different heat quantities can be calculated through the formula (2). Finally, the correspondence between the obtained refrigerating capacity and/or heating capacity and the rotation speed of the preset indoor fan, the frequency of the preset compressor and the opening and closing angle of the preset electromagnetic valve is shown in the following table 2.
For example, as shown in fig. 3, in determining the temperature difference based on the operation mode of the air conditioner in step S102, the heating mode may be selected first, and then the initial temperature may be set to 23 °, that is, the initial temperature T0The wind speed of the indoor fan is 23 degrees, and the wind speed of the indoor fan is high wind speed. Shutting down after the indoor temperature reaches 23 degrees, and measuring the indoor temperature after 30min to obtain the indoor current temperature T1. So that the temperature difference T-23-T can be determined1. After the floor area has been obtained in the previous step, the floor area can be obtained by the formula Q ═ J |23-T1The amount of heat lost per unit time of the room is calculated as | a/30. After the heat loss of the room in unit time is obtained, the heating capacity in the meter 2 can be compared, so that the rotating speed of the preset indoor fan, the frequency of the preset compressor and the opening and closing angle of the preset electromagnetic valve corresponding to the nearest heating capacity of the heat loss are used as the rotating speed of the current indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve, and the air conditioner is controlled to work according to the rotating speed of the current indoor fan, the frequency of the compressor and the opening and closing angle of the electromagnetic valve. It should be noted that the principle of determining the current rotational speed of the indoor fan, the current frequency of the compressor, and the current opening and closing angle of the electromagnetic valve in the cooling mode is similar to that of determining the current rotational speed of the indoor fan, the current frequency of the compressor, and the current opening and closing angle of the electromagnetic valve in the heating mode in this embodiment, and details are omitted here.
