Description
Technical Field
The invention relates to the technical field of air conditioner pipeline cleaning, in particular to a cleaning method for a pipeline of a central air conditioner air system.
Background
With the increasing awareness of people on cleaning air conditioners, the market for cleaning central air conditioners is also expanding continuously. In the cleaning of central air conditioners in large-scale venues, factories and public places, the cleaning of air ducts is an unavoidable item. According to the trunk and the branch of wind channel, the pipe diameter of wind channel has very big difference. The air outlets and branches on the air duct are numerous. Cleaning the duct is a very large project. The cleaning period of the air duct in a large-scale public place is often 1 month, and the whole project is time-consuming and labor-consuming. The cleaning effect is unstable, and the operation rules have no industrial standards. The existing cleaning method is summarized as follows:
1. the air duct cleaning robot can enter an air duct to scrub and collect dust aiming at a main air duct or an air duct with a larger pipe diameter. However, the robot cannot clean dust in the air duct at one time, the dust must be cleaned repeatedly, the efficiency is low, and the cleaning effect is directly related to the operation of the robot for several times.
2. The flexible shaft brush is used for limiting the air duct robot aiming at the branch air duct or the air duct with smaller pipe diameter. But the cross section of the path left by the flexible shaft brush during rotation is circular. The air duct is mostly square in cross-section so there will be some remaining debris in the corners. The efficiency is low.
3. When the cleaning agent touches the air duct with larger pipe diameter, constructors prefer to directly climb in, and the cleaning effect is better. But it is not feasible to do so with a relatively thin air duct. And people climb into the air duct, which belongs to the operation in a limited space, the danger coefficient is large, and dust and bacteria in the air duct also have great threat to the health of constructors.
4. When the air cleaner touches a thinner air duct, a self-made mop is used for stretching into the air duct from the air opening for scrubbing. The cleaning effect is unstable, and the cleaning of the mop is time-consuming and labor-consuming.
The cleaning method is a representative air duct method at the present stage. The efficiency is low, the cost is high, a large amount of manpower is required to be invested, and some potential safety hazards exist. The cleaning effect has a direct relationship with the number of cleaning repetitions of the constructor. The cleaning effect is good when the number of times of cleaning is large, and the effect is poor when the number of times of cleaning is small. The national sanitation standard of the centralized air-conditioning ventilation system in the public place is only a normative file, and has no mandatory execution reason, one reason is that the current cleaning industry has no unified operation standard, the cleaning cost is high, and many enterprises are difficult to bear if the mandatory execution is carried out. If a cleaning method which is simple to operate, low in cost and capable of realizing standardization is provided, the public health environment can be improved better.
In the existing cleaning methods of the air systems of the central air conditioners, the air pipe cleaning robot is still utilized at the front edge. After reviewing the existing patent documents, the devices or equipment for cleaning the inner wall of the pipe by using hydrodynamics and cleaning balls are only suitable for cleaning a circular pipe or a liquid pipeline with a smooth inner wall, and the air system pipeline of the central air conditioner has the following characteristics: the cross section is generally rectangular; are all non-standard pipes; the air pipe is provided with a plurality of air ports and air leakage places, so that the air pipe cannot be cleaned by injecting water like a common pipeline; the inner diameter of the air pipe is decreased progressively (so-called reducing) along with the increase of the air opening; the wind pipe is provided with a plurality of uneven parts which can be provided with screws, and the air outlet is provided with an opening iron prick; the iron sheet which is not completely cut off at the air outlet is possibly bent and rolled into the air pipe, so that the air pipe cleaning robot is blocked.
In summary, the existing cleaning method has low cleaning efficiency, poor safety and higher cleaning cost, the internal working condition of the central air-conditioning air system is very complicated, and the existing pipeline cleaning technology has low applicability to the field of cleaning of central air-conditioners.
