Rotation speed control method and system, device, and storage medium

A rotation speed control system, characterized in that, applied to a heat pump system, wherein the system comprises an electronic flow regulating valve and a compressor, both sides of the electronic flow regulating valve are provided with a temperature sensor and a pressure sensor, and the rotation speed control system comprises:

• a ratio data collection module, configured to collect actual data of the temperature sensors and the pressure sensors, and process to obtain temperature ratio data and pressure ratio data;
• an oil content prediction model obtaining module, configured to obtain a corresponding oil content prediction model through matching according to the temperature ratio data and the pressure ratio data;
• a predicted oil content data obtaining module, configured to input the temperature ratio data and the pressure ratio data into the oil content prediction model obtained through matching, and obtain predicted oil content data;
• and
• a rotation speed control module, configured to control a rotation speed of the compressor according to the predicted oil content data.
