Refrigerant leakage detection method and device, electronic equipment and computer storage medium

The invention discloses a refrigerant leakage detection method and device, electronic equipment and a computer storage medium, and the method comprises the steps that in the refrigeration process of refrigeration equipment, refrigerant charge in a compressor, a condenser, an evaporator and an expansion valve is obtained; summing the refrigerant charge in the compressor, the condenser, the evaporator and the expansion valve to obtain the current refrigerant charge; and in response to the situation that the refrigerant charging amount difference value between the obtained actual refrigerant charging amount and the current refrigerant charging amount is larger than the actual refrigerant charging amount of the first preset multiple, it is determined that refrigerant leakage happens to the refrigeration equipment. Therefore, whether refrigerant leakage occurs in the refrigeration equipment or not is judged according to the current refrigerant charge determined by calculating the refrigerant charge of the compress
