Further, the flushing port 22 is of a fixed shape structure, and the cross-sectional area of the flushing port is smaller than that of the pipe body 21, so that the air speed blown out from the flushing port 22 is increased, and the cleaning effect on the filter screen 121 and the standby filter screen 122 is ensured.
In the present embodiment, as shown in fig. 3, the flushing pipe 2 also adopts a guide rail form to freely move, wherein one end of the pipe body of the flushing pipe 2 is communicated with the air outlet pipe 132, a strip-shaped third guide rail 15 is arranged on the top of the unit body 1, the third guide rail 15 extends from the air outlet 131 to the filter screen 121, and a sliding block is arranged on the flushing pipe 2, and is correspondingly arranged on the third guide rail 15 so as to be capable of freely sliding between the air outlet 131 and the filter screen 121.
The first switch valve 221 is arranged on the flushing pipe 2, the first switch valve 221 controls the on-off of the flushing pipe 2, the second switch valve 222 is arranged on the air outlet pipe 132 to control the on-off of the air outlet pipe 132, and when the filter screen 121 needs to be cleaned, the second switch valve 222 is turned off and the first switch valve 221 is opened, so that air at the air outlet 131 flows out of the flushing pipe 2, and the air volume is guaranteed.
Preferably, the filter cleaning device may also comprise a second drive means for driving the flushing pipe 2 in a sliding manner, the specific drive means being referred to the first drive means, and other alternatives may be found in the prior art.
The application also provides a set of air conditioning unit, and the air conditioning unit comprises the filter screen cleaning device provided in the application.
The application also provides a cleaning method of the group of air conditioning units, which specifically comprises the following steps: when filter screen 121 satisfies clean condition, first drive arrangement drive filter screen 121 stretches out unit body 1, second drive arrangement drive flushing pipe 2 removes to the leeward side of filter screen 121, turn-off second ooff valve 222 and open first ooff valve 221, make the air-out only blow off from flushing pipe 2, and simultaneously, the new trend is filtered by reserve filter screen 122, for the process that washes filter screen 121 provides clean air, after the clearance, filter screen 121 automatic re-setting.
Similarly, when reserve filter screen 122 satisfies the clean condition, reserve filter screen 122 of first drive arrangement drive stretches out unit body 1, second drive arrangement drive flushing pipe 2 removes the leeward side to reserve filter screen 122, turn-off second ooff valve 222 and open first ooff valve 221, make the air-out only blow off from flushing pipe 2, and simultaneously, the new trend is filtered by reserve filter screen 122, for the process that washes reserve filter screen 122 provides clean air, after the clearance, reserve filter screen 122 automatic re-setting.
Meanwhile, the outlet air passing through the surface cooling section is blown to the external unit system from the flushing pipe 2, the hot water in the external unit system is greatly cooled, and the cooling tower and the dry cooler simultaneously play a cooling role at the moment, so that the condensation effect of the condenser is improved.
It should be noted that, the method for determining whether the filter screen 121 and the standby filter screen 122 meet the cleaning condition may be to detect whether the pressure difference between the two sides of the filter screen 121 and the standby filter screen 122 meets a preset value through a pressure difference table, and when the detected pressure difference between the filter screen 121 and the standby filter screen 122 has reached the preset value, the filter screen 121 and the standby filter screen 122 are cleaned.
This application has still set up dry cooler 3 on flushing pipe 2, and dry cooler 3 can carry out the temperature that heat recovery reduced the inside water of cold ware 3 to the cold wind in flushing pipe 2, and condenser heat transfer is continued to be got back to inside water to play energy-conserving effect.
The working form of the air conditioning unit adopting the application can be as follows:
(1) and (5) normal working conditions.
After entering the unit from the fresh air section, the fresh air is firstly filtered through the filter screen 121 and then passes through the standby filter screen 122, because the fresh air is filtered, the pollution degree of the filter screen of the standby filter screen 122 can be almost ignored, the fresh air is refrigerated by the surface cooling section 13 and then is sent into the room through the air outlet pipe 132 by the air feeder, and the first switch valve 221 is closed. In the external unit system, high-temperature and high-pressure gas from the compressor enters a condenser, and exchanges heat with the condenser through a cold water source, namely a cooling tower and a dry cooler, wherein only the cooling tower plays a role in cooling.
(2) And cleaning the filter screen.
The unit operation a period, because the pollutant piles up in the windward side of filter screen 121, the filter screen efficiency of worrying reduces, and the pressure differential in both sides exceeds the setting value, and flush pipe department blast gate is opened this moment, and the play tuber pipe 132 is closed, and flush pipe 2 removes to the top of reserve filter screen 122, and filter screen 121 rises. Meanwhile, fresh air is filtered by the standby filter screen 122 to provide clean air for the backwashing process. Because the area that dams in the wind gap diminishes, clean air flow rate increases, blows off filter screen new trend side pollutant, and filter screen 121 and flushing pipe 2 reset after the cleanness. In the outer unit system, clean air refrigerated by the surface cooler in the unit is blown through the dry cooler, so that hot water in the surface cooler is greatly cooled, and the cooling tower and the dry cooler play a cooling role at the same time, so that the condensation effect of the condenser is improved.
(3) Cleaning the standby filter screen.
After the unit is back washed for several times, the pollution degree of the filter screen of the standby filter screen 122 reaches a set value, the principle is basically the same as that of the standby filter screen, fresh air is filtered by the primary filter screen 121, and a cleaning air port is positioned at the initial position (the top of the surface cooling section) for cleaning. At the moment, the dry cooler and the dry cooler in the outer machine system play a cooling role at the same time.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
