Energy-saving defrosting structure of air conditioner

Abstract

The invention provides an energy-saving defrosting structure of an air conditioner. The energy-saving defrosting structure of the air conditioner comprises an air conditioner external unit shell, a fan, a copper pipe, a compressor and fins, wherein the fins are vertically distributed in the external unit shell in the manner of shutter; the fins and spaces formed by the fins incline relative to the horizontal position; the copper pipe is connected with the compressor after vertically passing through one higher ends of the fins; and the fan is arranged at one side of the fins. According to the energy-saving defrosting structure of the air conditioner, the copper pipe is concentrated at one side of the fins, and by adopting such a structure, a nearby ice cake is melted firstly when the copper pipe emits heat, and the copper pipe is not bound after the ice cake is melted; subsequently, the surface of the ice cake, which is contacted with the fins, is melted into a layer of water, and the ice cake glides under the action of gravity by the water to achieve the goal that the ice cake can be removed without completely melting the ice cake, thereby, electric energy is saved.

Description

Technical field [0001] The invention relates to the field of air-conditioning auxiliary equipment, in particular to an air-conditioning energy-saving defrosting structure. Background technique [0002] In 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 b...

AI Technical Summary

Problems solved by technology

[0003] By running the cooling mode, part of the indoor heat is used to melt the ice cubes on the fins of the outdoor unit. Due to the structure of the fins and copper tubes, the ice cubes are firmly entangled with the fins Together, the air conditioner must be run for a period of time to completely melt the ice before completing the defrosting process, which consumes a lot of electricity
