Air conditioner

Abstract

The invention provides an air conditioner, and belongs to the technical field of air conditioners. By arranging the branch refrigerant pipeline, a part of refrigerant flowing out of the condenser exchanges heat with the control module, and the control module is cooled by utilizing the low-temperature characteristic of the refrigerant. Meanwhile, condensate water in the water pan exchanges heat with the control module through the first water path, and heat generated by the control module is further absorbed. The dual heat exchange mechanism remarkably improves the heat management efficiency, and ensures that the control module is kept in a proper temperature range in the operation process. Meanwhile, after condensate water collected by the water pan exchanges heat with the control module through the first water path, the temperature rises, then the condensate water can be conveyed into the humidifier through the second water path for humidification, in the process, recycling of the condensate water is achieved, waste of water resources is reduced, energy consumption of the humidifier is further reduced, and the energy consumption of the humidifier is reduced. Due to the high-temperature condensate water, the heating requirement of the humidifier can be reduced.
