Embodiment 1
[0020] figure 1 It is a flow chart of a compressor adjustment method provided by Embodiment 1 of the present invention. This method is applicable to the temperature control of inverter air conditioners. The method is executed by the compressor adjustment device provided by the embodiment of the present invention. The device can use software and / or hardware, the device can be integrated into refrigeration equipment, such as an air conditioner. like figure 1 shown, including:
[0021] S101. Obtain an outlet air temperature when the compressor is working normally, and calculate an ideal output power of the frequency converter when the outlet air temperature is in a normal range.
[0022] An air conditioner is a device that can regulate and control parameters such as temperature, humidity, cleanliness, and circulation velocity of the air in an indoor environment. In this embodiment, the normal operation of the compressor refers to the working state of the compressor after the s...

[0038] figure 2 It is a flowchart of a compressor adjustment method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments, and provides a preferred specific method for calculating the ideal output power of the frequency converter, specifically: real-time Detecting the input current value and voltage value of the frequency converter, calculating the power value of the frequency converter; calculating the ideal output power of the frequency converter according to the relationship between the ideal working efficiency ratio and the power value.
[0039] like figure 2 As shown, correspondingly, the method of the embodiment of the present invention includes:
[0040] S201. Acquire the outlet air temperature when the compressor is working normally.
[0041] S202. When the outlet air temperature is within the normal temperature range, detect the input current value and voltage value of the frequency converter in real ...
Embodiment 3
[0054] image 3 It is a flowchart of a compressor adjustment method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments, and provides a preferred process of initializing the frequency of the compressor before obtaining the outlet air temperature , specifically: determining the initial frequency of the compressor by comparing the current ambient temperature value with the preset temperature value, and maintaining the initial frequency until the outlet air temperature meets the preset condition. like image 3 As shown, the corresponding method of this embodiment includes:
[0055] S301. Determine an initial frequency of the compressor by comparing a current ambient temperature value with a preset temperature value, and maintain the initial frequency until the outlet air temperature meets a preset condition.
[0056] Specifically, in refrigeration equipment, the output temperature has a positive correlation with ...
