Through the mode, when the controller in the constant-speed air conditioner receives the indoor temperature data sent by the indoor temperature sensor, whether the operation mode of the constant-speed air conditioner is the refrigeration mode or the heating mode is determined according to the change trend of the indoor temperature, then the indoor temperature change rate is calculated according to the indoor temperature data and compared with the preset threshold value, and the liquid storage tank between the first electromagnetic valve and the second electromagnetic valve is enabled to store or release the refrigerant by controlling the first electromagnetic valve and the second electromagnetic valve according to the comparison result and the operation mode where the air conditioner is located, so that the refrigerant circulation quantity in the constant-speed air conditioner is adjusted, the refrigeration or heating capacity of the air conditioner is controlled, the indoor temperature change rate is controlled, the large indoor temperature fluctuation is avoided, and the comfort degree of the air conditioner in use can be improved. Compared with the prior art, the constant-speed air conditioner is more frequent in starting and stopping, and the starting and stopping frequency of the air conditioner can be reduced, so that the service life of an air conditioner compressor is prolonged.
Referring to fig. 4, when the constant speed air conditioner is in a cooling mode, fig. 4 is a first detailed schematic flow chart illustrating that the temperature change rate is compared with a preset threshold value, and the first electromagnetic valve and the second electromagnetic valve are controlled according to a comparison result and the operation mode, so as to adjust the refrigerant circulation amount in the constant speed air conditioner. Step S20 includes:
step S21, comparing the temperature change rate with the first threshold and the second threshold;
step S22, when the temperature change rate is greater than or equal to the second threshold, opening the first electromagnetic valve and closing the second electromagnetic valve, thereby reducing the refrigerant circulation amount in the constant speed air conditioner;
step S23, when the temperature change rate is greater than the first threshold and less than the second threshold, closing the first solenoid valve and the second solenoid valve, thereby maintaining the refrigerant circulation amount in the constant speed air conditioner;
and step S24, when the temperature change rate is less than or equal to the first threshold, closing the first electromagnetic valve and opening the second electromagnetic valve, thereby increasing the refrigerant circulation amount in the constant speed air conditioner.
In the embodiment of the present invention, the preset threshold includes a first threshold and a second threshold, and the first threshold is smaller than the second threshold. When the constant speed air conditioner is in a refrigeration mode, comparing the temperature change rate obtained by calculating according to the indoor temperature data with the first threshold and the second threshold, and controlling the first electromagnetic valve and the second electromagnetic valve correspondingly according to the comparison result, thereby adjusting the refrigerant circulation volume in the constant speed air conditioner. Wherein the range between the first threshold and the second threshold is a temperature variation range which is comfortable for a user. For example, a user generally feels comfortable when the ambient temperature rises or falls by 1 ℃ within 3-5min, i.e., the temperature change rate is 0.2-0.33 ℃/min, so the first threshold value can be set to 0.2 ℃/min, and the second threshold value can be set to 0.33 ℃/min. Of course, the first threshold and the second threshold may be set according to user preferences in different countries and different regions. For convenience of description, in the embodiment of the present invention, the first threshold value is 0.2 ℃/min, and the second threshold value is 0.33 ℃/min.
When the temperature change rate is greater than or equal to a second threshold value, namely s is greater than or equal to 0.33 ℃/min, the indoor temperature change is too fast, and because the air conditioner is in a refrigeration mode, the refrigerant in the air conditioner flows into the indoor unit from the outdoor unit through the throttle valve, at the moment, the first electromagnetic valve is opened, the second electromagnetic valve is closed, so that part of the refrigerant enters the liquid storage tank, the refrigerant circulation quantity in the constant-speed air conditioner is reduced, at the moment, the refrigeration capacity of the air conditioner can be reduced, and the temperature reduction rate is reduced;
when the temperature change rate is greater than the first threshold value and less than the second threshold value, namely s is greater than 0.2 and less than 0.33 ℃/min, indicating that the indoor temperature change rate is proper at the moment, closing the first electromagnetic valve and the second electromagnetic valve so as to maintain the refrigerant circulation volume in the constant-speed air conditioner at the moment;
when the temperature change rate is less than or equal to the first threshold value, namely s is less than or equal to 0.2 ℃/min, the indoor temperature change is too slow, at the moment, the first electromagnetic valve is closed, the second electromagnetic valve is opened, so that the refrigerant in the liquid storage tank enters the air conditioner again for circulation, the refrigerant circulation quantity in the constant-speed air conditioner is increased, at the moment, the refrigerating capacity of the air conditioner can be improved, and the temperature reduction rate is accelerated.
Referring to fig. 5, when the constant speed air conditioner is in a heating mode, fig. 5 is a second detailed flow diagram illustrating that the temperature change rate is compared with a preset threshold value, and the first electromagnetic valve and the second electromagnetic valve are controlled according to the comparison result and the operation mode, so as to adjust the refrigerant circulation volume in the constant speed air conditioner. Step S20 further includes:
step S21, comparing the temperature change rate with the first threshold and the second threshold;
step S26, when the temperature change rate is greater than or equal to the second threshold, closing the first electromagnetic valve and opening the second electromagnetic valve, thereby reducing the refrigerant circulation amount in the constant speed air conditioner;
step S27, when the temperature change rate is greater than the first threshold and less than the second threshold, closing the first solenoid valve and the second solenoid valve, thereby maintaining the refrigerant circulation amount in the constant speed air conditioner;
step S28, when the temperature change rate is smaller than or equal to the first threshold, the first electromagnetic valve is opened, and the second electromagnetic valve is closed, so as to increase the refrigerant circulation amount in the constant speed air conditioner.
In the embodiment of the invention, when the constant speed air conditioner is in a heating mode, the temperature change rate calculated according to indoor temperature data is compared with the first threshold and the second threshold, and the first electromagnetic valve and the second electromagnetic valve are correspondingly controlled according to the comparison result, so that the refrigerant circulation quantity in the constant speed air conditioner is adjusted.
When the temperature change rate is greater than or equal to a second threshold value, namely s is greater than or equal to 0.33 ℃/min, the indoor temperature change is over fast, and because the air conditioner is in a heating mode, the refrigerant in the air conditioner flows into the outdoor unit from the indoor unit through the throttle valve, the first electromagnetic valve is closed at the moment, the second electromagnetic valve is opened, so that part of the refrigerant enters the liquid storage tank, the refrigerant circulation quantity in the constant-speed air conditioner is reduced, the heating capacity of the air conditioner is reduced at the moment, and the temperature rise rate is reduced;
when the temperature change rate is greater than the first threshold value and less than the second threshold value, namely s is greater than 0.2 and less than 0.33 ℃/min, indicating that the indoor temperature change rate is proper at the moment, closing the first electromagnetic valve and the second electromagnetic valve so as to maintain the refrigerant circulation volume in the constant-speed air conditioner at the moment;
when the temperature change rate is less than or equal to the first threshold value, namely s is less than or equal to 0.2 ℃/min, the indoor temperature change is too slow, at the moment, the first electromagnetic valve is opened, the second electromagnetic valve is closed, and the refrigerant in the liquid storage tank enters the air conditioner again for circulation, so that the circulation quantity of the refrigerant in the constant-speed air conditioner is increased, at the moment, the heating capacity of the air conditioner can be improved, and the temperature rise rate is accelerated.
In addition, in a specific embodiment, the range of the temperature change rate at which the human body may feel comfortable in the temperature rising environment and the temperature falling environment is not consistent, and therefore, the preset threshold may include a plurality of values, and when the air conditioner is in different operation modes, the comparison may be performed with different preset thresholds.

In the embodiment of the present invention, steps S30 and S40 are located between steps S10 and S20, and in a specific embodiment, steps S30 and S40 may also be located before step S10. Considering that when a user turns on the air conditioner, the indoor temperature may be overheated or overcooled, and it is urgently needed to adjust the indoor temperature to reach the target temperature set by the user, at this time, in order to improve user experience, when the difference between the indoor temperature and the target temperature is large, and when the difference between the indoor temperature and the target temperature is large, the indoor temperature change rate may be larger, therefore, a third threshold may be set in the preset threshold, and the third threshold is larger than the second threshold.
