The invention discloses an electric control box. The electric control box comprises a processor, a heating control module, a heating circuit and a power module; the power module is connected with the processor and the heating control module which is connected with the heating circuit; when an outdoor unit is powered on, the processor acquires the environment temperature in the electric control box, and when the acquired environment temperature is lower than a first preset temperature, a current work mode of the processor is switched into a dormancy mode; and when the environment temperature in the electric control box is lower than a second preset temperature, the heating control module controls the heating circuit to perform heating. The invention further discloses a control method of the electric control box. By means of the electric control box and the control method of the electric control box, when the environment temperature in the electric control box is lower than the second preset temperature, the heating circuit is used for heating the electric control box; and when the environment temperature in the electric control box is lower than the first preset temperature, the processor starts the dormancy mode, and therefore electronic components in the electric control box can be protected, and the service life of an air conditioner is prolonged.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an electric control box and a control method for the electric control box. Background technique [0002] With the rapid development of air-conditioning technology, air-conditioning plays an increasingly important role in people's daily life. [0003] However, the electronic components of the outdoor unit of the air conditioner have a temperature limit during operation. Generally, the lowest working ambient temperature of the electronic components is -20°C. If the ambient temperature is lower than the minimum operating temperature of the electronic components, the electronic components will be damaged. The unstable working state affects the working characteristics of electronic components, which in turn affects the performance of the air conditioner, and even causes the air conditioner to stop working when the temperature exceeds the operating temperature range of the ele...
