Embodiment Construction
[0039] The present invention firstly provides a control method for preventing the temperature of the power module of the outdoor unit of the air conditioner from being too high. figure 1 It is a schematic flowchart of a control method for preventing an overheating of a power module of an outdoor unit of an air conditioner according to an embodiment of the present invention.
[0040] see figure 1 , the control method of the present invention includes: obtaining the temperature of the power module; controlling the shutdown of the air conditioner when the temperature of the power module exceeds a preset safety threshold; And continue to detect the temperature of the power module. That is to say, the control method of the present invention controls the start and stop of the air conditioner according to the temperature of the power module, and controls the short stop of the air conditioner when the temperature of the power module exceeds the preset safety threshold, which can effe...

The invention relates to an air conditioner and a control method for preventing the temperature of a power module of an outdoor unit of the air conditioner from being too high. The control method comprises the steps that the temperature of the power module is acquired; when the temperature of the power module exceeds a preset safety threshold, the air conditioner is controlled to stop; and when the time of the air conditioner is stopped for a first preset duration, the air conditioner is started again, and the temperature of the power module is continuously detected. The air conditioner comprises a temperature acquisition module and a controller, wherein the temperature acquisition module is used for acquiring the temperature of the power module, and the controller is configured to controlthe air conditioner to stop when the temperature of the power module exceeds the preset safety threshold, and start the air conditioner again after the time of the air conditioner stopping lasts forthe first preset duration. According to the air conditioner and the control method, when the temperature of the power module exceeds the preset safety threshold, the air conditioner is controlled briefly to stop, and the situation that the refrigeration effect of the air conditioner is influenced due to the temperature of the power module is too high can be effectively avoided.
Description
technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner and a control method for preventing the temperature of a power module of an outdoor unit thereof from being too high. Background technique [0002] When the existing heat pump air conditioner is running in high temperature cooling state, there may be problems such as the power module of the outdoor unit running at too high temperature, and the heat dissipation is not timely, which affects the normal operation of the air conditioner. [0003] In the prior art, a radiator is usually added near the power module, and the operation of the radiator is controlled according to the temperature of the power module, so as to dissipate heat from the power module. However, this method increases the cost and energy consumption of the air conditioner, and also makes the structure of the air conditioner more complicated. Contents of the invention [0004] An object of the first aspect ...
