Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The features of the terms first and second in the description and in the claims of the invention may explicitly or implicitly include one or more of these features. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
The control method, device, electronic equipment and storage medium for adjusting the frequency of the compressor of the air conditioner according to the present invention are described below with reference to fig. 1 to 3.
For the variable frequency air conditioner, the computer board program usually corresponds the outdoor environment temperature and the compressor frequency one to one, when the outdoor environment temperature reaches a certain value, the temperature sensor of the outdoor unit of the air conditioner converts the temperature value into a digital signal and transmits the digital signal to the computer board of the outdoor unit, and the control system locks the compressor frequency. However, the disadvantages of this frequency modulation method are: when two adjacent frequency points are switched with each other, if the ambient temperature at the time is changed drastically, for example, when the ambient temperature heating rate reaches 0.02 ℃/s, the air conditioner should start to reduce the frequency when the ambient temperature exceeds 48 ℃, but in order to prevent the compressor from being influenced by frequent frequency fluctuation, after the program receives the temperature digital signal and calculates, a frequency reduction instruction is sent out after two minutes to control the compressor to reduce the frequency. When the compressor begins to reduce the frequency, the ambient temperature rises to 50.4 ℃, at the moment, the exhaust temperature of the compressor needs to exceed 51 ℃ to realize heat exchange, and the corresponding exhaust pressure reaches 3.2MPa or higher. At high frequencies of the compressor, the compressor input current will rise considerably in order to reach high pressures, often with peaks exceeding the IPM safety current or the power supply safety current, resulting in compressor shutdown.
The compressor can be operated smoothly by reducing the frequency of the compressor, but if the compressor is operated at low frequency all the time, the refrigerating capacity of the air conditioner is correspondingly reduced, so that the indoor temperature cannot be reduced at a later time. Based on this, the invention provides a control method for adjusting the frequency of the compressor of the air conditioner, which is used for solving the above problems.
As shown in fig. 1, in an embodiment of the present invention, a method for controlling frequency adjustment of an air conditioner compressor specifically includes the following steps:
step 101: and acquiring the heating rate of the outdoor environment in real time.
Specifically, the outdoor unit of the air conditioner is provided with a temperature sensor, and the temperature sensor can detect the outdoor environment temperature in real time, so that the actual heating rate of the outdoor environment can be calculated.
Step 102: judging whether the actual temperature rise rate reaches a target temperature rise rate or not; step 103: if the actual heating rate is less than the target heating rate, controlling the running frequency of the compressor according to the outdoor environment temperature; if the actual heating rate is equal to or greater than the target heating rate, controlling the compressor to reduce to the lowest frequency within the adjusting time, and keeping the lowest frequency to operate; wherein the adjustment time is 20-30 s.
Specifically, when the actual heating rate of the outdoor environment is smaller than the target heating rate, the compressor automatically adjusts the frequency of the compressor according to the outdoor environment temperature, so that the compressor is in a stable running state; and when the actual temperature rising rate of the outdoor environment is equal to or greater than the target temperature rising rate, controlling the compressor to be reduced to the lowest frequency in a shorter time and operating at the lowest frequency.
Further, in one embodiment of the present invention, the target heating rate may be 0.01 ℃/s, the adjustment time is a relatively short time, such as 20-30s, and when the heating rate of the outdoor environment is equal to or greater than 0.01 ℃/s, the compressor is controlled to be reduced to the lowest frequency within 20-30s, such as the lowest frequency of the compressor is 35Hz, and the compressor is kept operating at the frequency of 35 Hz. When the compressor runs at the lowest frequency, the temperature sensor of the outdoor unit still detects the outdoor environment temperature, and if the obtained actual heating rate of the outdoor environment is less than 0.01 ℃/s, the compressor automatically adjusts the frequency of the compressor according to the outdoor environment temperature and works according to the frequency corresponding to the outdoor environment temperature.
It can be understood that: when the compressor works according to the frequency corresponding to the outdoor environment temperature, if the outdoor environment temperature changes again, if the obtained actual temperature rising rate is larger than the target temperature rising rate again, the compressor reduces the frequency to the lowest frequency again in the adjustment time, and keeps the lowest frequency to operate.
In the embodiment of the invention, when the acquired outdoor environment temperature rise rate is equal to or more than 0.01 ℃/s, the compressor is reduced to the lowest frequency in a very short time, and because the frequency reduction time is short, the lag time of the compressor exhaust is also short, the exhaust temperature is reduced in a short time, and the exhaust pressure is also reduced, so that the stable operation of the compressor can be ensured without shutdown.
According to the control method for adjusting the frequency of the compressor of the air conditioner, provided by the embodiment of the invention, when the temperature rising rate of the outdoor environment is higher, the compressor is controlled to work at the lowest frequency within a shorter time, the exhaust lag time of the compressor is shortened, and the exhaust temperature of the compressor is reduced within a shorter time, so that the exhaust pressure is reduced, the stable operation of the compressor is ensured, and the shutdown event can not occur.
Further, in an embodiment of the present invention, the step of acquiring the actual temperature rising rate of the outdoor environment in real time further includes: and acquiring the outdoor environment temperature in real time, and determining the actual heating rate of the outdoor environment based on the outdoor environment temperature.
Specifically, a temperature sensor is arranged in the outdoor unit, the temperature sensor can acquire the outdoor environment temperature in real time, and the heating rate of the indoor and outdoor environments in unit time, namely the actual heating rate of the outdoor environment, can be calculated according to the change of the outdoor environment temperature.
Further, in an embodiment of the present invention, before the step of determining whether the actual temperature increase rate reaches the target temperature increase rate, the method further includes: and acquiring a target temperature rise rate, wherein the target temperature rise rate is 0.01 ℃/s.
Specifically, in the present embodiment, in order to reduce the influence of the rapid temperature rise of the outdoor environment on the compressor, the unit of the temperature rise rate is set to be ℃/s, that is, when the external environment changes, the change of the ambient temperature can be detected rapidly. Further, the target temperature increase rate is set to 0.01 ℃/s according to the experimental results, and of course, the target temperature increase rate may be faster for some special environments, such as 0.015 ℃/s.
In one embodiment of the present invention, the control method of the frequency adjustment of the compressor of the air conditioner further comprises: and controlling the outdoor fan to increase the rotating speed in the process of keeping the lowest frequency operation of the compressor.
Specifically, in the process that the compressor operates at the lowest frequency, the rotating speed of the outdoor fan can be increased to enhance heat exchange, so that the temperature of a refrigerant in the condenser is reduced, and the exhaust temperature and the exhaust pressure of the compressor are reduced. Specifically, the rotating speed of the outdoor fan is increased to 960rpm from the normal rotating speed. Generally, the normal rotation speed of the outdoor fan is 840 rpm.
Further, in an embodiment of the present invention, the method for controlling the frequency adjustment of the compressor of the air conditioner further includes: after the rotating speed of the outdoor fan is increased and after the compressor runs stably for a preset time, the rotating speed of the outdoor fan is controlled to be reduced.
Specifically, after the rotating speed of the outdoor fan is increased and the compressor runs stably for a preset time, the rotating speed of the outdoor fan can be reduced, so that the rotating speed of the outdoor fan is reduced to a normal rotating speed, such as 840 rpm. Optionally, in an embodiment of the present invention, the preset time is 1 minute.
