[0027] Example: A non-stop defrosting method for an intelligent air conditioner

[0028] See attached Figure 1-2 , pre-build a non-stop defrosting air conditioner, the air conditioner includes a compressor, a four-way valve, a condenser, a throttling device and an evaporator that sequentially form a cycle connection. The condenser includes radiating fins and heat exchange tubes, and the radiating fins are spaced and distributed on the heat exchange tubes.

[0029] It also includes a first temperature sensor, a second temperature sensor, a controller, a defrosting pipeline and a driving circuit. The first temperature sensor ring is arranged on the heat exchange tube of the condenser for detecting the tube temperature of the condenser, and the second temperature sensor ring is arranged outside the outdoor heat exchanger for detecting the outdoor ambient temperature. The defrosting pipeline is a pipeline structure, one end of the pipeline structure is connected to the inlet en...

Abstract

The invention relates to a non-stop defrosting method for an intelligent air conditioner. The air conditioner a compressor, a four-way valve, a condenser, a throttle device and an evaporator, whereinthe compressor, the four-way valve, the condenser, the throttle device and the evaporator are sequentially and circularly connected. The air conditioner further comprises a first temperature sensor, asecond temperature sensor, a controller, a defrosting pipe and a driving circuit. The method comprises the steps that the temperature of a conveying pipe of the condenser is detected through the first temperature sensor every other N, and the detected current pipe temperature is sent to the controller; at the same time, outdoor environment temperature is detected through the second temperature sensor every other N, and the detected current environment temperature is sent to the controller; the current pipe temperature is compared with the current environment temperature through a judging module; if the absolute value of a temperature difference between the current pipe temperature and the current environment temperature is larger than 17 DEG C, and the current pipe temperature is lower than -7 DEG C, a control module sends a signal to the driving circuit so as to control the driving circuit to drive a solenoid valve to open the defrosting pipe, so that a part of refrigerants with heatare sent into the condenser for defrosting of the condenser; otherwise, the solenoid valve is switched off, and normal heating of the intelligent air conditioner is carried out.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to a non-stop defrosting method for an intelligent air conditioner. Background technique [0002] In the existing air conditioner, when the outdoor unit is frozen during the heating process, it usually needs to be shut down before defrosting. In this way, the heating cannot be performed during the shutdown process. Will cause discomfort to users. [0003] In view of this, a non-stop defrosting method for an intelligent air conditioner is proposed, which is the research subject of the present invention. Contents of the invention [0004] In view of the above problems, the object of the present invention is to provide a non-stop defrosting method for an intelligent air conditioner to solve the problem that the existing air conditioner needs to be shut down during the defrosting process. [0005] In order to achieve the above object, the present invention adopts the foll...
