[0025] Clearly and completely describe the technical scheme in the embodiments of the present application in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0026] Before describing the specific embodiments of the present application in detail, first introduce the working principle of the glycol heat recovery system in the prior art (as shown in Figure 1

[0027] The glycol heat recovery system mainly includes a fresh air side heat recovery coil 13 arranged in the fresh air air conditioning box 11 and a exhaust air side heat recovery coil 17 arranged in the exhaust air air conditioning box 16. The fresh air side heat recovery coil 13 and the exhaust air side heat recovery coil 17 are connected in series through a circulating pump 19 and a connecting pipe to form a heat exchange loop, and a mixed solution of glycol and water is added in the loop as a heat exchange agent. The fresh air filter 12 is arranged at the air inlet end of the fresh air air conditioning box 11 for filtering dust and impurities in the fresh air. The fresh air side fan 11 is arranged in the fresh air air conditioning box 11 for guiding the indoor air. The exhaust air side fan 18 is arranged in the exhaust air air conditioning box 16 for guiding the outdoor air.

[0028] In summer working condition, the air in the room exchanges heat with the surface of the exhaust air side heat recovery coil 17, thereby reducing the temperature of the glycol solution as the heat exchange medium in the exhaust air side heat recovery coil 17. The circulating pump 19 pressurizes and delivers the heat exchange agent to the fresh air side heat recovery coil 13. At this time, the fresh air exchanges heat with the surface of the fresh air side heat recovery coil 13, thereby reducing the temperature of the fresh air and increasing the temperature of the heat exchange agent in the fresh air side heat recovery coil 13. The heat exchange agent with increased temperature flows into the exhaust air side heat recovery coil 17 again under the action of the circulating pump 19 and exchanges heat with the indoor exhaust air, thereby completing a cold recovery cycle.

[0029] By spraying water to cool the exhaust air side heat recovery coil 17, the temperature of the glycol solution in the exhaust air side heat recovery coil 17 can be effectively reduced, and the heat exchange efficiency of the glycol heat recovery system can be increased. Generally, atomized water is used for cooling, which can further increase the cooling effect. The atomized water continuously condenses on the exhaust air side heat recovery coil 17 and the fins to form water droplets flowing down.

[0030] As shown in Figures 2 to 5 A glycol heat recovery system exhaust air side atomization cooling condensate collecting device, including a mounting box 2 for containing and fixing the exhaust air side heat recovery coil 17, the fins 110 on the surface of the exhaust air side heat recovery coil 17 are also located in the mounting box 2, the two sides of the mounting box 2 are adaptively opened according to the arrangement of the fins 110, for the airflow to pass through the gap between the fins 110 and exchange heat with the exhaust air side heat recovery coil 17.​

[0031] The installation box 2 is provided with a water collecting groove on each side, which is formed by the box wall of the installation box 2 and a plurality of combination plates arranged outside the installation box 2.

[0032] As a specific embodiment, the plurality of combination plates respectively include a bottom plate 31 arranged at the bottom of one side of the installation box 2, preferably at the side of the air inlet and air outlet of the fin 110, an extension plate 32 arranged at the overhanging end of the bottom plate 31 extending upward, and a first side plate 33 and a second side plate 34 arranged at the two ends of the bottom plate 31 between the installation box 2 and the extension plate 32. The installation box 2, the bottom plate 31, the extension plate 32, the first side plate 33 and the second side plate 34 jointly form a water collecting groove, and the box wall of the installation box 2 is further provided with a water outlet (not shown in the figure) communicating with the water collecting groove, and a filter screen 23 is embedded in the water outlet.

[0033] In use, after the atomized water condenses on the exhaust side heat recovery coil 17 and the fin to form water droplets flowing down, the water flow is concentrated at the bottom of the installation box 2, and the concentrated water is filtered by the filter screen 23 and then enters the water collecting groove. At this time, the water inside the water collecting groove plays a role of increasing the specific heat capacity. Compared with the state without water accumulation, the water in the water grooves on both sides of the installation box 2 will absorb part of the heat, reduce the temperature of the surrounding air, further effectively reduce the temperature of the ethylene glycol solution in the exhaust side heat recovery coil 17, and increase the cold recovery effect.

[0034] Further, the top of the water collecting groove is provided with a mesh plate 4, which plays a protective role at the top of the water collecting groove and prevents large-volume impurities from entering the water collecting groove. At the same time, the mesh structure of the mesh plate 4 ensures that the water inside the water collecting groove is in a non-insulated state with the outside air, so as to ensure that the water inside the water collecting groove normally exchanges heat with the surrounding air.

[0035] As a specific embodiment, the inner sides of the first side plate 33 and the second side plate 34 are provided with a support plate 37, and the mesh plate 4 is erected on the top of the water collecting groove through the support plate 37.

[0036] Further, the first side plate 33 and the second side plate 34 extend upward to approach the top of the installation box 2, and the top ends of the first side plate 33 and the second side plate 34 are transitionally connected by a top plate 35. The purpose of this design is to first increase the overall rigidity of the water collecting groove, secondly to enclose the fin 110 to play a protective role, and finally to increase the overall aesthetics of the device.

[0037] Further, the bottom side of the installation box 2 is provided with a cleaning port 21, which is sealed by a detachable sealing cover 24. The impurities filtered by the filter screen 23 in the installation box 2 can be cleaned out through the cleaning port 21. A sealing gasket 22 is arranged between the sealing cover 24 and the cleaning port 21 to ensure the sealing strength of the cleaning port 21 and prevent water leakage when the cleaning port 21 is used to clean the impurities.

[0038] Specifically, in the embodiment, the sealing cover 24 is fixed on the installation box 2 by wing bolts, which is convenient for disassembly and assembly.

[0039] Further, the first side plate 33 or the second side plate 34 is provided with a water overflow hole 36, which is connected to an external drainage system, such as an external sewer pipe, and the excess water is directed to the water collecting groove to prevent the excess water from overflowing and affecting the living environment.

[0040] Preferably, the exhaust side heat recovery coil pipe 17 and the fin 110 have a gap with the inner bottom surface of the installation box 2, and the gap height is greater than the water collecting groove height, so as to prevent the exhaust side heat recovery coil pipe 17 and the fin 110 from being soaked in water.

[0041] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.
