Abstract

The invention relates to an efficient air conditioner and a method for improving defrosting efficiency of a condenser of the air conditioner. The air conditioner comprises a compressor, a four-way reversing valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger, which are connected in turn; a heating defrosting loop is arranged between the compressor and the outdoor heat exchanger, and consists of a defrosting tube, a control valve and a current limit device; one end of the defrosting tube is connected with an output end of the compressor; the defrosting tube is connected with the control valve and the current limit device in turn along an outlet of the compressor; and one end of the current limit device is connected with an inlet of a heating cyclic working condition of the outdoor heat exchanger to form a circulation loop with the compressor. The efficient air conditioner has the advantages that the air conditioner has high energy efficiency ratio compared with the prior electric heating wire to defrost; and length and inner diameter of a capillary tube are adjusted according to the used environmental temperature, so as to achieve optimal defrosting effect.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a high-efficiency air conditioner equipped with a heating device on a condenser. Background technique [0002] At present, the air conditioners used in the alpine environment are mainly for heating. They are used for air conditioners in the alpine environment. When the surface temperature of the evaporator is lower than 0°C, the moisture in the air will condense into frost on the surface of the evaporator. The frost layer covers the surface of the evaporator, which hinders the contact between the coil and the fins and the air, greatly reducing the heat transfer efficiency of the heat exchanger. With the increase of the thickness of the frost layer, the cross section of the air duct becomes smaller, the air volume decreases, the heat exchange conditions become increasingly severe, and the surface temperature of the evaporator decreases continuously, so that the evaporating temperature also de...
