Embodiment Construction

[0058] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0059] figure 1 Shown is a schematic flowchart of a control method for delaying frosting of an air conditioner according to an embodiment of the present invention, including the following steps S100-S300.

[0060] In step S100, the temperature of the external coil of the air conditioner is continuously sampled. During the heat exchange process between the outdoor heat exchanger (evaporator) and the outdoor air, since the temperature of the outdoor heat exchanger is low (often around 0°C), and the air humidity on the outdoor side is high, it passes through the low temperature heat exchanger After heat exchange, part of the water in the ambient air will be condensed and left in the outdoor heat exchanger. Due to the low surface temperature...

Abstract

The invention provides a control method and device for air conditioner frosting delay and an air conditioner, and relates to the technical field of air conditioners. The control method comprises the steps that the outer coil pipe temperature of the air conditioner is continuously sampled; according to the situation of changing of the air conditioner outer coil pipe temperature along with the time, whether the frosting delay condition is met or not is judged; and when the frosting delay condition is met, a heating element is controlled to heat a heat exchanger, and frosting delay operation is conducted. The first-order derivative is solved for the outer coil pipe temperature to judge the changing tendency of the outer coil pipe temperature, the inflection point where a frost layer enters the worsening period is found according to the judgment condition, and the frosting delay operation is started. The heating element is used for eliminating the frost layer and condensate water, the air conditioner frosting time is prolonged, accordingly, the time when the air conditioner enters the automatic defrosting mode is prolonged, and the heating effect and the air conditioner usage comfort are guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method and device for delaying frosting of an air conditioner and an air conditioner. Background technique [0002] With the development of air-conditioning technology and the gradual improvement of people's living standards, more and more users will choose to use air-conditioning for heating in winter. A very serious problem encountered by existing air conditioners using air as a heat source during heating operation in winter is the problem of frosting on the surface of the evaporator (outdoor heat exchanger). [0003] During the heating process of the air conditioner in winter, the evaporator exchanges heat with the outdoor ambient temperature and brings the outdoor heat into the room, thereby achieving the room heating effect. When the surface temperature of the evaporator is lower than the dew point temperature of the surrounding air, condensation will occ...
