Embodiment approach
[0072] In one embodiment, the method also includes:
[0073] When the variable frequency air conditioner is in the oil return mode for a preset oil return period, the oil return mode is exited, and the variable frequency air conditioner is controlled to operate in a state before entering the oil return mode.
[0074] The aforementioned preset oil return duration can be adjusted and set as required, which is not limited in this embodiment of the present application. During the preset oil return time in the oil return mode, the room temperature and humidity requirements and the inverter air conditioner’s air temperature and humidity requirements can be calculated periodically and the opening of the heating element, humidification element and other components can be controlled to adjust the temperature and humidity. Real-time compensation realizes ultra-high precision temperature and humidity control during the oil return process.
[0075] The oil return control method of the in...

The invention discloses a variable frequency air conditioner oil return control method and device, electronic equipment and a medium. The method comprises the steps that under the condition that the variable frequency air conditioner enters an oil return mode, the current frequency of a compressor is adjusted to the preset oil return frequency for work; the room temperature and humidity requirement is obtained, the air outlet temperature and humidity requirement of the variable frequency air conditioner is obtained, and the room temperature and humidity requirement is used for representing the first adjusting force needed by the deviation between the current temperature and humidity and the expected temperature and humidity of a room corresponding to the variable frequency air conditioner; the air outlet temperature and humidity requirement is used for representing the second adjusting force required by the deviation condition between the current air outlet temperature and humidity of the variable frequency air conditioner and the air outlet temperature and humidity of the variable frequency air conditioner before oil return; and when the variable frequency air conditioner is in the oil return mode, temperature and humidity compensation operation is controlled according to the room temperature and humidity requirements and the air outlet temperature and humidity requirements of the variable frequency air conditioner.
Description
technical field [0001] The invention relates to the technical field of frequency conversion air conditioners, in particular to an oil return control method, device, electronic equipment and medium for frequency conversion air conditioners. Background technique [0002] The air conditioning system used in some occasions has very high requirements on the accuracy and stability of temperature and humidity. For example, the frequency conversion air conditioner of the ultra-high precision laboratory strictly requires the allowable fluctuation range of temperature and relative humidity. [0003] At present, the air conditioner in the laboratory generally adopts the frequency conversion compressor to achieve the purpose of energy saving, environmental protection and linear control. When the variable frequency compressor operates in the low frequency band for a long time, there will be risks of poor oil return and poor lubrication, which will lead to wear and failure of the moving ...
