Embodiment Construction

[0011] refer to figure 1 , the present invention is described in detail by the following examples.

[0012] In the air-conditioning system, a set of additional defrosting devices is connected in parallel next to the expansion valve 11 of the four-way valve 5 reversing the defrosting device, which is the present invention, which can increase the amount of refrigerant circulation during the defrosting cycle, so that the heat exchange effect of the fin evaporator 3 can be improved. increase, and finally shorten the defrosting time significantly. The refrigerant stored in the liquid receiver 7 is controlled by the electromagnetic valve 14 and the electromagnetic regulating valve 13, and reaches the flap condenser 2, the four-way valve 5, and the flap evaporator 3 in the pipeline and circulates. The pressure switch A and The pressure switch B is set on the pipelines on both sides of the compressor 6 to adjust the pressure of the refrigerant. The gas component 10 is designed betwee...

Abstract

The invention discloses a defrosting device of an air conditioner, mainly comprising an electromagnetic control valve, a temperature sensor and an electromagnetic valve; in the case that defrosting is carried out, the electromagnetic valve is closed, and the electromagnetic control valve regulates the electromagnetic valve to open through the temperature sensed by the temperature sensor; and when the defrosting is not carried out, the electromagnetic control valve is normally closed. The defrosting device disclosed by the invention is additionally arranged into an air conditioning system, thus the circulating mass of a refrigerant can be increased during defrosting circulation, the heat exchange efficiency of the evaporator is improved, and finally the defrosting time is obviously shortened. Experiments show that when a four-way valve inverts to defrost, defrosting time can be shortened by 3-5 seconds through connecting one defrosting device of the air conditioner beside an expansion valve in parallel, the average operation efficiency of an air conditioner unit is improved by 8% in a low-temperature frosting working condition in winter, the electricity consumption of the air consumption can be saved and the comfortableness of users can be enhanced.

Description

technical field [0001] The invention relates to electronic components in an air-conditioning system, in particular to an air-conditioning defrosting device used in the air-conditioning system. Background technique [0002] The ideal defrosting method in the air-conditioning system is four-way valve reversing defrosting, which is also widely used at present, but this defrosting method generally has the problems of long defrosting cycle and incomplete defrosting. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an air conditioner defrosting device used in an air conditioner system. [0004] The technical solution adopted by the present invention is: in the air conditioning system, a set of additional defrosting devices is connected in parallel next to the expansion valve of the four-way valve reversing defrosting device, which is the present invention, which can increase the refrigerant circulation duri...
