Description

Technical Field

[0001] The invention belongs to the field of air conditioning, and in particular relates to an integrated communication room high-efficiency self-evaporating backflow prevention air conditioner. Background Art

[0002] Traditional air conditioners use a split design, with the condenser and compressor installed outside the room, and the evaporator and expansion valve installed in the computer room to cool the room. This arrangement may cause condensed water on the evaporator to flow into the room. If the computer room uses this split air conditioner, the outdoor unit mounting bracket will be arranged outside the computer room. This is not suitable for situations where space is limited and the computer room is far away. There is also a risk of condensed water backflow damaging the communication equipment in the computer room.

[0003] In addition to split air conditioners, integrated air conditioners are also commonly used in communication rooms. Compared with split air conditioners, integrated air conditioners do not require external wall mounting brackets and are more convenient to install. However, integrated air conditioners may also cause condensed water to be unable to be automatically discharged to the outside. Usually, a collection box is set up next to the air conditioner to collect the condensed water of the air conditioner. When the collection box is full, someone needs to be sent to pour out the water in the collection box. This type of integrated air conditioner requires personnel to regularly check and drain the water, which requires a certain amount of manpower investment and is not conducive to the efficient operation of production and life. There is also a risk of condensed water overflowing and backflowing into the computer room, causing equipment damage.

[0004] Therefore, there is a need in the art for an integrated air conditioner with low manpower input and in which condensed water can evaporate automatically. Summary of the invention

[0018] (III) Beneficial effects

[0019] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0020] In the present invention, the condensed water generated by the evaporator is collected by the first water collecting tank, and then heated by the condensation heat exchange device and enters the second water collecting tank. The evaporating cotton in the second water collecting tank absorbs and evaporates the condensed water. When the evaporation rate in the second water collecting tank is insufficient and the condensed water is large, the condensed water level in the second water collecting tank will rise. When the liquid level in the second water collecting tank is higher than the set value, the liquid level detection device arranged in the second water collecting tank sends an alarm to the control system, and the control system sends an instruction to control the compressor to stop working.

[0021] The second water collecting tank is connected to the third water collecting tank. When the evaporation speed of the evaporating cotton decreases, the electric heating device in the third water collecting tank heats the condensed water. The condensed water boils and evaporates under the action of the electric heating device. At this time, the condensed water enters the dehumidification pipe in the form of steam. The centrifugal fan is turned on to send the condensed water vapor into the steam exhaust pipe, and then discharged through the hot air outlet. In the process of steam discharge, due to the temperature difference between the inner and outer walls of the steam exhaust pipe, a small amount of condensed water vapor condenses and refluxes on the inner wall of the steam exhaust pipe. The refluxed condensed water will flow from the inner wall of the steam exhaust pipe into the condensed water reflux device, and then flow from the condensed water reflux device into the third water collecting tank. Finally, it boils and evaporates again under the action of the electric heating device and is discharged through the hot air outlet. The present invention quickly evaporates the condensed water through the evaporating cotton and the electric heating device, and uses the added anti-backflow pipeline and the centrifugal fan to convert the condensed water into high-temperature steam to discharge the air conditioner. The condenser waste heat is used to generate heat while preventing the condensed water from backflow. BRIEF DESCRIPTION OF THE DRAWINGS
