Abstract

The invention provides a rotating speed control method and system, equipment and a storage medium. The rotating speed control method and system are applied to a heat pump system. The heat pump system comprises a throttling short pipe and a compressor, and the two sides of the throttling short pipe are each provided with a temperature sensor and a pressure sensor. The rotating speed control method comprises the steps that actual data of the temperature sensors and the pressure sensors are collected, the data are processed to obtain temperature ratio data and pressure ratio data, and the data are matched to corresponding oil content prediction models; according to the temperature ratio data and the pressure ratio data, predicted oil content data are obtained; and the rotating speed of the compressor is controlled according to the predicted oil content data. According to the rotating speed control method, the four oil content prediction models are obtained through a large amount of data training, so that the heat pump system can predict the oil content of the compressor according to the readings of the temperature sensors and the pressure sensors, the rotating speed of the compressor is controlled according to the predicted oil content of the compressor, automatic control over the compressor is achieved, oil shortage of the compressor is prevented, and the safety of the heat pump system is improved.

Description

technical field [0001] The invention relates to the technical field of heat pump system control, in particular to a speed control method, system, equipment and storage medium. Background technique [0002] With the promotion of electric vehicles, people have higher and higher requirements for electric vehicle air-conditioning systems. At present, the common electric vehicle air-conditioning systems mostly use heat pump systems. This causes the viscosity of the refrigerant on the low-pressure side to rise, causing the oil in the compressor in the heat pump system to dissolve in the refrigerant, making it difficult for the compressor to return oil, and may even cause oil shortage or damage to the compressor. [0003] The flow rate of the refrigerant in the heat pump system is a major factor in changing the oil content of the compressor. In the prior art, the staff usually make further judgments on the speed control of the compressor by visually observing the actual oil content...
