In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Fig. 1 is a schematic structural view of a combined air conditioner according to an embodiment of the present invention, as shown in fig. 1, and referring to fig. 2 and 3, an embodiment of the present invention provides a combined air conditioner, which is an end device of a central air conditioning system, including a housing 100, a filter 200 and a surface cooler 300 located in the housing 100, and a spray device 400, which are sequentially arranged along a flow direction of an air flow. The filter 200 is used to filter the air flow, thereby improving the quality of the circulating air flow. The surface air cooler 300 is used for heat exchange with air flowing through itself. The spray device 400 is used for simultaneously spraying and washing the filter 200 and the surface cooler 300. Specifically, when the filter 200 is clogged and the surface cooler 300 drops dust, the filter 200 and the surface cooler 300 may be simultaneously subjected to spray rinsing. Therefore, the combined air conditioner does not need to be turned on, the spraying device 400 can be controlled to conveniently spray and flush the filter 200 and the surface cooler 300 at any time, time and labor are saved, and working efficiency is improved. The simultaneous cleaning process significantly saves cleaning time compared with the simultaneous cleaning of the filter 200 and the surface air cooler 300, so that the working time of the combined air conditioner is prolonged.
In some embodiments of the present invention, the combined air conditioner further includes a pressure difference detecting device 500, and the pressure difference detecting device 500 is used for monitoring the pressure difference between the air inlet side of the filter 200 and the air outlet side of the surface air cooler 300. The filter 200 absorbs contaminants during operation, and the filter 200 is easily clogged. The surface air cooler 300 is liable to fall dust during operation, thereby reducing the ventilation gap of the surface air cooler 300. When the filter 200 is blocked or the surface air cooler 300 has too much dust, a large pressure difference is formed between the air inlet side of the filter 200 and the air outlet side of the surface air cooler 300, and the pressure difference value between the front of the filtering section and the rear of the surface cooling section is monitored in real time. Through comparing differential pressure with the pressure difference value that sets for, if the pressure difference value is greater than the design pressure difference value, pressure difference detection device 500 can judge that filter 200 blocks up or surface cooler 300 falls dirt too much, and filter 200 and surface cooler 300 need wash, opens spray set 400, sprays and washes filter 200 and surface cooler 300.
Further, the rinsing time period was 5 minutes. After the washing is completed, the combined air conditioner is operated for one hour to blow water on the filter 200 and the surface air cooler 300. The magnitude of the differential pressure value is determined again, and if the differential pressure value is smaller than the designed differential pressure value, the spraying device 400 does not work. If the differential pressure value is greater than the design differential pressure value, the spray device 400 works again, the previous washing process is repeated, the combined air conditioner runs for one hour after washing is completed to blow dry the water on the filter 200 and the surface air cooler 300, the magnitude of the differential pressure value is judged again, and the spray device 400 does not work again until the differential pressure value is less than the design differential pressure value.
Certainly, in other embodiments, the pressure difference detection device 500 may also be configured to monitor a pressure difference between the air inlet side and the air outlet side of the filter 200, when the filter 200 is gradually blocked after operating for a period of time, the pressure difference between the air inlet side and the air outlet side of the filter 200 is compared with a set pressure difference value, when the pressure difference is greater than the set pressure difference value, the pressure difference detection device 500 may determine that the filter 200 is blocked, the filter 200 needs to be cleaned, and the surface cooler 300 may be cleaned while the filter 200 is cleaned. Since the filter 200 is more easily clogged, the filter 200 and the surface cooler 300 can be timely cleaned by detecting the pressure difference across the filter 200.
The arrangement is convenient for monitoring the conditions of the filter 200 and the surface air cooler 300 at any time, so that the judgment that the filter 200 and the surface air cooler 300 need to be cleaned is made in time, and the problem that the combined air conditioner is not smooth in ventilation and influences air circulation due to blockage of the filter 200 and the surface air cooler 300 is avoided.
In some embodiments of the present invention, the pressure difference detecting device 500 includes two pressure sampling pipes 510, and the pressure sampling ports of the two pressure sampling pipes 510 are respectively communicated with the air inlet side of the filter 200 and the air outlet side of the surface air cooler 300.
In some embodiments of the present invention, the spraying device 400 includes a water storage device and a spraying part, and the spraying part utilizes the water in the water storage device to spray and flush the filter 200 and the surface air cooler 300 simultaneously. The spray part may spray the filter 200 and the surface cooler 300 at the same time. For example, the spray part may include a plurality of spray headers which are uniformly distributed on the corresponding planes of the inlet and outlet surfaces of the filter 200 and the surface air cooler 300, and clean both the inlet and outlet surfaces of the filter 200 and the surface air cooler 300.

The humidifier 700 also saves water resources by humidifying with water in the water storage device, and the humidifier 700 works in a controlled manner, saving manpower. And the structure is simple, and a plurality of water storage devices are not needed.
