Compressor frequency regulation method, control apparatus, heat exchange device and electronic device

A heat exchange device, comprising:

• a heat exchange assembly, including a compressor, a condenser and an evaporator connected to form a heat exchange cycle;
• and
• a controller, used to control the compressor to perform a method for adjusting a frequency of the compressor, including:
• determining a first operating frequency based on an ambient temperature;
• operating the compressor at the first operating frequency;
• acquiring a first exhaust temperature of the compressor operating at the first operating frequency;
• and
• in accordance with a determination that the first exhaust temperature is equal to or greater than a first preset temperature:
• controlling the compressor to perform frequency reduction processing to reduce the first operating frequency to a second operating frequency, and making a second exhaust temperature of the compressor operating at the second operating frequency be lower than the first preset temperature, wherein controlling the compressor to perform frequency reduction processing to reduce the first operating frequency to a second operating frequency comprises controlling the compressor to operate at the second operating frequency, and wherein the first preset temperature is associated with a maximum exhaust temperature of the compressor, the heat exchange assembly is arranged inside a housing of a heat exchange device, and the method includes:
• in accordance with a determination that the first exhaust temperature of the compressor reaches the maximum exhaust temperature of the compressor, sounding an alarm or shutting down the compressor.
