Problems solved by technology
This control scheme is prone to a problem, that is, the detection of the start signal of the compressor does not mean that the compressor can start normally; for example, when the ambient temperature in the north is very low, especially the variable frequency compressor may fail to start during the start process; if At this time, the electric auxiliary heater is powered off, and the lubricating oil in the compressor cannot be effectively preheated, which further causes the compressor to fail to start normally, which in turn causes the user to be unable to use the machine, and multiple failures of the compressor will affect the compressor. life and reliability

The invention discloses a control method for a compressor, the compressor and a heat pump system. According to the control method for the compressor provided by the technical scheme, whether the compressor is successfully started or not serves as a judging standard of whether an electric auxiliary heat device is stopped or not to guarantee that after the compressor is successfully started, the electric auxiliary heat device is stopped; the defect that when the compressor is not successfully started, the electric auxiliary heat device is stopped, and thus the compressor cannot be normally started further is overcome; and therefore, according to the technical scheme, the preheating effectiveness of the electric auxiliary heat device is improved, and normal starting of the compressor is guaranteed.
Description
technical field [0001] The invention relates to the technical field of heat pump systems, in particular to a compressor control method, a compressor and a heat pump system. Background technique [0002] Most heat pump systems have a compressor; after the compressor stops, it is necessary to ensure that the lubricating oil inside has a certain degree of superheat to prevent the refrigerant from migrating into the lubricating oil, causing the lubricating oil to be diluted; , The lubricating oil is vaporized rapidly due to the low temperature, resulting in a reduction of the lubricating oil. For this reason, in the prior art, an electric auxiliary heater is arranged at the bottom of the compressor for heating the lubricating oil. When the compressor start signal is detected, the electric auxiliary heater is powered off, and when the compressor stop signal is detected, the electric auxiliary heater is powered on to start heating the lubricating oil. [0003] The control standa...
