Problems solved by technology
[0003] By running the cooling mode, part of the heat in the room is used to melt the ice on the fins of the outdoor unit, and the compressor is frequently switched on and off, which consumes a lot of electric energy. At the same time, the indoor temperature drops greatly during defrosting, which brings discomfort to people. sense

The invention provides a rapid defrosting device of an air conditioner. The rapid defrosting device of the air conditioner comprises an air conditioner external unit shell, an expansion valve, a copper pipe, a compressor and fins, wherein the copper pipe is inserted into the fins arranged in parallel in the manner of U shape to form a heat exchanger of an air conditioner external unit; both ends of the copper pipe are respectively connected with one end of the compressor and one end of the expansion valve; the copper pipe at the other end of the expansion valve passes through the interior of a heat-storage thermal-insulation tank; a working medium is filled in the heat-storage thermal-insulation tank; a heat conduction pipe is also inserted into the fins; the heat conduction pipe forms an independent loop in the fins; a pump body is arranged in the loop; the pump body is electrically connected with an air conditioner defrosting control circuit; heat conduction oil is filled in the heat conduction pipe; and the heat conduction pipe passes through the interior of the heat-storage thermal-insulation tank. According to the rapid defrosting device of the air conditioner, rapid defrosting can be realized on the air conditioner without switching operating modes, thereby, a great amount of electric energy is saved.
Description
Technical field [0001] The invention relates to the field of air-conditioning auxiliary equipment, in particular to a fast defrosting device for air-conditioning. Background technique [0002] In the heating mode, the external unit of the air conditioner blows cold air, and the temperature of the heat exchanger is several degrees below zero or 10 degrees. At this time, the water vapor in the outside air will condense on the fins of the external unit, and then be frozen into ice cubes. If there is no defrosting, the external unit will be blocked by ice cubes, unable to dissipate heat, and the ice will become thicker and thicker. Eventually, the refrigerant in the external unit will not be able to evaporate, and the pressure will be too low. The system will trip the low-voltage protection and shut down. When a certain condition is reached (each air conditioner has been set before leaving the factory: for example, the fin temperature is lower than the ambient temperature by X° ...
