Problems solved by technology
Fin heat dissipation requires a large reserved space for fins, and the wind field of the air conditioner has a great influence on the heat dissipation effect
Although the cooling effect of the refrigerant pipe is better, if the temperature of the refrigerant pipe is too low, it may cause condensed water in the electric control box, and there is a risk of short circuit.

The invention discloses an air conditioner and a cooling control method thereof. The air conditioner includes: a compressor, a control valve assembly, an outdoor heat exchanger, a first throttling element, an auxiliary heat exchanger, an electric control box, an electric control heat exchanger, and first to third temperature detection devices. The first refrigerant passage of the auxiliary heat exchanger is connected with the first throttling element, and the second refrigerant passage of the auxiliary heat exchanger is connected with the first throttling element through the second throttling element. The first to third temperature detection devices are respectively connected to the electric control module, the first temperature detection device is used to detect the electric control temperature of the electric control module, the second temperature detection device and the third temperature detection device are respectively used to detect the temperature inside the electric control box The dry bulb temperature and wet bulb temperature of the environment, wherein the electronic control module controls the opening degree of the second throttling element according to the detection results of the first to third temperature detection devices. According to the air conditioner in the embodiment of the present invention, it is ensured that the electric control module is prevented from short-circuiting due to condensed water in the electric control box while cooling the electric control module.
Description
technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to an air conditioner and a cooling control method thereof. Background technique [0002] Nowadays, frequency conversion air conditioners are more and more widely used, and the electronic control module corresponding to the frequency conversion compressor is relatively complicated. The heat dissipation of the electronic control module has always been a concern in the industry. Generally, fins are used to dissipate heat, and there is also a way to force cooling by bonding refrigerant tubes and electronic control modules. Fin heat dissipation requires a large reserved space for the fins, and the air field of the air conditioner has a great influence on the heat dissipation effect. Although the cooling effect of the refrigerant pipe is better, if the temperature of the refrigerant pipe is too low, condensed water may be generated in the electric control box, a...
