Problems solved by technology

However, when the outdoor ambient temperature or the temperature of the outer wall of the air conditioner compressor is very low, the traditional method is to detect the outdoor ambient temperature or the temperature of the outer wall of the compressor through a temperature sensor during the operation of the compressor. Doing work and generating heat, so these two measured temperature values ​​do not represent the temperature of the refrigerant, and cannot strictly correspond to the physical state of the refrigerant in the compressor. There may be cases where it is judged that the refrigerant has a liquid state based on the temperature, but the actual refrigerant does not exist in a liquid state. Misjudgment of the situation, resulting in the waste of electric energy during the operation of the compressor

Abstract

The invention relates to a compressor heating device control method in the operational stage of a compressor. The method includes the steps that S1, a reference database of compressor electric power relative to the outdoor unit environment temperature and compressor operating frequency is established in advance; S2, the real-time values of the outdoor unit environment temperature, compressor winding phase currents and busbar voltages are obtained, and the actual electric power and operating frequency of the compressor are further calculated; and S3, a corresponding compressor electric power consumption reference value is searched for in the reference database according to the outdoor unit environment temperature and the compressor operating frequency, and the compressor electric power reference value is compared with an actual electric power value; and when the deviation value between the actual electric power value and the electric power reference value is greater than a power deviation threshold value, a heating device is started and the electric power of the heating device is adjusted in accordance with the deviation value. According to the compressor heating device control method in the invention, the refrigerant state inside the compressor is judged through real-time power, misjudgment can be effectively avoided, and electric losses are reduced. The invention further provides a computer readable storage medium and air-conditioner for realizing the method.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a compressor heating device control method in the compressor running phase; and also relates to a computer-readable storage medium and an air conditioner for realizing the compressor heating device control method. Background technique [0002] In an ultra-low temperature environment, the current control methods for the heating device of the air conditioner compressor are mostly based on the outdoor ambient temperature or the temperature of the outer wall of the air conditioner compressor. However, when the outdoor ambient temperature or the temperature of the outer wall of the air conditioner compressor is very low, the traditional method is to detect the outdoor ambient temperature or the temperature of the outer wall of the compressor through a temperature sensor during the operation of the compressor. Doing work and generating heat, so these two measured tempe...
