Embodiment 1

[0033] figure 1 It is a flow chart of the automatic dust removal of the unit according to the embodiment of the present invention, as figure 1 As shown, the method includes the following steps:

[0034] Step S101, monitoring the outdoor temperature and the temperature of the outer tube of the condenser;

[0035] Step S102, judging whether the dust removal condition is met according to the outdoor temperature and the temperature of the outer pipe; if yes, execute step S103, if not, execute step S105;

[0036] Step S103, judging whether the shutdown condition is reached according to the indoor temperature; if yes, execute step S104, if not, execute step S105;

[0037] Step S104, performing dust removal operation;

[0038] Step S105, keeping the unit running normally.

[0039] In this embodiment, various temperature parameters are combined to determine the dust removal condition and shutdown condition in sequence, and the dust removal operation is performed when both conditio...

Embodiment 2

[0049] image 3 It is an automatic dust removal flow chart of an air conditioner external unit according to an embodiment of the present invention, as image 3 As shown, the method of automatic dust removal of the outdoor unit of the air conditioner is: through the outdoor temperature T 外环 and the corresponding outer tube temperature T 外管 To judge whether to meet the dust removal conditions, T 外管 When it is greater than the corresponding preset threshold listed on the right side of Table 1 above, it is judged that the condenser is seriously polluted and the dust removal condition is met. After that, compare T 内环 with T 设定 Whether the temperature-to-temperature shutdown condition is met (also referred to as the shutdown condition for short), if T 内环 -T 设定 ≤T, the range of T value can be determined according to the actual situation, for example, T can be set to (-5~0) ℃, then it is judged that the above temperature-to-temperature shutdown condition is met, and the dust rem...

Embodiment 3

[0051] corresponds to figure 1 Introduced automatic dust removal method for the unit, this embodiment provides an automatic dust removal device for the unit, such as Figure 4 The structural block diagram of the automatic dust removal device of the unit shown, the device includes:

[0052] The outer ring temperature sensor is used to monitor the outdoor temperature;

[0053] Condenser temperature sensor for monitoring the temperature of the outer tube of the condenser;

[0054] The controller is used to judge whether the dust removal condition is reached according to the outdoor temperature and the outer pipe temperature; if it is reached, it further judges whether the shutdown condition is reached according to the indoor temperature, and sends a dust removal command to the unit after the shutdown condition is reached.

[0055] In this embodiment, various temperature parameters are combined to determine the dust removal condition and shutdown condition in sequence, and the d...

Abstract

The invention discloses an automatic unit dust removal method and device and a unit. The method includes the steps of monitoring the outdoor temperature and the temperature of an outer pipe of a condenser, judging whether the dust removal conditions are met or not according to the outdoor temperature and the temperature of the outer pipe, if yes, further judging whether shutdown conditions are metor not according to the indoor temperature, and executing the dust removal operation after the shutdown conditions are met. By combining various temperature parameters, the dust removal conditions and the shutdown conditions are sequentially judged, and the dust removal operation is executed when the two types of conditions are both met. Thus, by combining environment factors, the automatic unitdust removal is realized, the problems of refrigerating capacity attenuation and poor reliability caused by the dust accumulation or dirt blockage of the condenser are avoided, the reliability of theunit is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of unit technology, in particular to a method, device and unit for automatic dust removal of a unit. Background technique [0002] At present, the outdoor unit of the air conditioner has been running outdoors for many years, especially when it is installed in the region with severe sand and dust in the Middle East. The heat exchanger of the outdoor unit is easy to accumulate dust, resulting in a serious decline in heat exchange effect, and the cooling capacity will be lower and lower. At the same time, it is prone to high pressure. Protection, exhaust protection and other reliability issues. And because the air-conditioning external unit is installed on the outer wall of a high-rise building, it is not conducive to the maintenance of after-sales engineers. How to realize the automatic dust removal of the condenser of the external unit without affecting the normal operation of the air conditioner has become a difficul...
