Problems solved by technology

These dust and other sundries are generally bad conductors of heat, which will affect the heat dissipation effect of the condenser. In addition, dust and other sundries will also block the air from flowing through the surface of the condenser, reducing the heat transfer effect.

Embodiment Construction

[0057] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] refer to figure 1 , figure 1 It is a schematic flow chart of a preferred embodiment of the dust removal control method for the outdoor unit heat exchanger of the air conditioner according to the present invention, the method comprising:

[0059] S10. Obtain the outside temperature and inside temperature of the heat exchanger of the outdoor unit in real time according to a preset time interval.

[0060] A temperature sensor is respectively arranged on the outside and inside of the outdoor unit heat exchanger 1, which are respectively a first temperature sensor 10 and a second temperature sensor 20, such as Figure 2a and Figure 2b As shown, the heat exchange surface of the outdoor unit heat exchanger 1 is the inner side. In one embodiment, the temperature sensors can be respectively arranged in the middle o...

Abstract

The invention discloses a dust removal control method for a heat exchanger of an outdoor unit of an air conditioner. The method comprises the following steps: acquiring the outer side temperature and the inner side temperature of the heat exchanger of the outdoor unit in real time at a preset time interval; determining whether dust removal start conditions are met according to the outer side temperature and the inner side temperature of the heat exchanger of the outdoor unit; controlling an outdoor fan to rotate reversely to perform dust removal treatment on the heat exchanger of the outdoor unit if the outer side temperature and the inner side temperature of the heat exchanger of the outdoor unit meet the dust removal start conditions. The invention further discloses a dust removal control device for the heat exchanger of the outdoor unit of the air conditioner. With adoption of the method and the device, dust removal can be performed on the heat exchanger of the outdoor unit automatically, and the heat exchange effect of the heat exchanger of the outdoor unit is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a dust removal control method and device for an outdoor heat exchanger of an air conditioner. Background technique [0002] In the field of household air conditioner manufacturing, household air conditioners mainly include: compressors, condensers, throttling devices, and evaporators. At present, household air conditioners are generally of the air-cooled type, and their heat exchangers are generally of the air-cooled fin type, that is, the fin-covered copper tube type. At present, some high-efficiency single-coolers use a parallel-flow all-aluminum condenser for the outdoor unit condenser in order to improve the heat exchange capacity of the condenser, reduce the condensation temperature and improve the energy efficiency ratio of the whole machine. There are several holes inside each flat tube of the parallel flow all-aluminum condenser, and there are ribs on the hole wall, the r...
