Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air-cooled air conditioning indoor exhaust system. Background Technology

[0002] The working principle of an indoor air conditioner is as follows: the compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser (outdoor unit) to dissipate heat and become a low-temperature, high-pressure liquid refrigerant. After passing through a throttling valve, it enters the evaporator (indoor unit), where the liquid refrigerant vaporizes into a low-temperature gaseous refrigerant, absorbing a large amount of heat during the vaporization process. The indoor unit's fan then blows indoor air across the evaporator, bringing cool air. The gaseous refrigerant then returns to the compressor to be compressed again, entering the next cycle.

[0003] In practical engineering applications, some functional air-conditioned rooms require ventilation. The design often suffers from the problem of "directly exhausting the cooler indoor air to the outside, resulting in a waste of low-temperature cooling resources." Therefore, research can explore how to utilize the lower-temperature exhaust air from indoor air-conditioned rooms, creating conditions for it to be discharged towards the outdoor unit of an air-cooled air conditioner. This mixture of air and air under different operating conditions will influence and lower the condensing temperature of the air conditioning unit, effectively improving its cooling efficiency, saving electricity, and contributing to reducing carbon emissions. Utility Model Content

[0004] In order to improve the cooling efficiency of air conditioning units, save power consumption, and reduce operating costs, this application provides an air-cooled air conditioning indoor exhaust system.

[0005] The air-cooled air conditioning indoor exhaust system provided in this application adopts the following technical solution: A wind-cooled air conditioning indoor exhaust system includes a roof structure, a first outdoor air conditioning unit, a first air conditioning duct, and a first exhaust fan. The first outdoor air conditioning unit is installed on the roof structure, and the first air conditioning duct is laid above the roof structure and is used to supply air to the room. The first exhaust fan is installed on the roof structure and close to the first outdoor air conditioning unit. The first exhaust fan is connected to a public restroom in the room and is used to exhaust the air from the public restroom to the periphery of the first outdoor air conditioning unit.

[0006] By adopting the above technical solution, the core task of the outdoor unit during air conditioning cooling is to dissipate the "high-temperature heat" generated by the refrigerant after compression to the outside through the condenser (the refrigerant condenses from a high-temperature, high-pressure gas into a low-temperature, high-pressure liquid). This heat dissipation process depends on the outside air drawn in by the outdoor unit's fan—the lower the air temperature, the greater the temperature difference between the air and the condenser, and the higher the heat dissipation efficiency; conversely, the higher the air temperature, the more difficult the heat dissipation. The higher the outdoor air temperature, the greater the energy consumption during air conditioning cooling; the lower the temperature, the lower the energy consumption.

[0007] The exhaust air from the indoor public restroom is horizontally discharged to the installation platform of the first outdoor air conditioning unit via the first exhaust fan, mixing with the outdoor intake air of the air conditioner and adjusting the intake air temperature. By recycling and utilizing the indoor exhaust air, the cooling efficiency of the air-cooled air conditioning unit is improved, power consumption is saved, operating costs and carbon emissions are reduced, and low-carbon development is promoted.

[0008] Alternatively, the air from the standard indoor public restroom can be centrally exhausted into the vertical shaft of the roof structure, and then introduced into the air intake environment of the first outdoor air conditioning unit through ducts, so that it mixes with the outdoor air intake of the air conditioning unit and the intake air temperature is adjusted.

[0009] Preferably, it also includes a second outdoor air conditioning unit, a second air conditioning duct, and a second exhaust fan. The second outdoor air conditioning unit is installed on the main roof structure, the second air conditioning duct is laid above the main roof structure and is used to supply air to the room, the first air conditioning duct and the second air conditioning duct are symmetrically distributed on both sides of the main roof structure, and the second exhaust fan is close to the second outdoor air conditioning unit and is used to exhaust the air in the indoor office area to the periphery of the second outdoor air conditioning unit.

[0010] By adopting the above technical solution, the air in the indoor office area is exhausted to the second air conditioner outdoor unit through the second exhaust fan, so that it mixes with the outdoor air intake of the air conditioner and adjusts the intake air temperature. Alternatively, the exhaust air from the total heat exchanger unit in the standard floor indoor office area can be centrally exhausted to a vertical shaft leading to the roof, and then led to the intake air environment of the second air conditioner outdoor unit through air ducts, so that it mixes with the outdoor air intake and adjusts the intake air temperature.

[0011] Preferably, both the inlet and outlet of the first exhaust fan and the second exhaust fan are equipped with steel wire protective nets.

[0012] By adopting the above technical solution, the exhaust fan blades rotate at high speed during operation. If directly exposed, this could lead to accidental entanglement of fingers, clothing, etc., causing cuts, entanglement, and other safety accidents. The steel wire mesh provides physical isolation, preventing direct contact with the rotating parts and reducing safety risks. The steel wire mesh also possesses sufficient strength to protect the exhaust fan's inlet and outlet frames, blades, and other components from external impacts (such as bumps during handling or the impact of wind-blown debris), reducing physical damage to the equipment's casing or core components.

[0013] Preferably, the air outlets of both the first and second air conditioning ducts are exhaust louvered vents.

[0014] By adopting the above technical solutions, the blades of the louvered air vents (which can be arranged horizontally or vertically) can guide the airflow direction through angle design (such as horizontal diffusion, oblique air supply, etc.), preventing the airflow from blowing directly onto the human body and reducing the discomfort of direct cold air. The louvered blades form a grid-like structure, which can effectively block external debris (such as dust, insects, paper scraps, small particles) from entering the air duct, preventing foreign objects from clogging the air duct, contaminating the filter, or damaging the fan, reducing system maintenance costs, and extending equipment life.

[0015] Preferably, it also includes an indoor air supply component, which is disposed on the roof structure and is used to supply air to the room. The indoor air supply component includes an air supply duct and a blower. One end of the air supply duct is connected to the outside air and the other end is connected to the room. The blower is disposed on the end of the air supply duct near the room and is used to supply air to the room.

[0016] Preferably, the indoor air supply assembly is provided in several groups.

[0017] By adopting the above technical solution, the blower (whose core is the impeller) is driven by a motor to rotate at high speed, creating a pressure difference at its inlet and outlet using fluid mechanics principles (the impeller rotation generates centrifugal force or axial thrust). The air duct, as a closed pipe structure, serves as a "channel" for airflow, precisely guiding the airflow generated by the blower to a designated location and preventing disorderly air diffusion. Through the synergistic effect of "power drive + directional delivery," the two achieve orderly airflow within the space.

[0018] Preferably, it also includes an indoor smoke exhaust assembly, which includes a smoke exhaust pipe and a fire-fighting smoke exhaust fan. One end of the smoke exhaust pipe is connected to the outside atmosphere, and the other end is connected to the interior. The fire-fighting smoke exhaust fan is installed on the smoke exhaust pipe and is used for smoke exhaust.

[0019] Preferably, the indoor smoke exhaust components are provided in two sets, and the two indoor smoke exhaust components are symmetrically distributed on both sides of the roof body.

[0020] By adopting the above technical solution, the negative pressure generated by the smoke exhaust fan is transmitted to the smoke exhaust outlet in the fire area through the smoke exhaust pipe, which "draws" high-temperature smoke (including CO, toxic gases, and particulate matter) from the room, corridor and other spaces into the pipe; the smoke exhaust pipe, as a closed channel, directs the smoke to the smoke exhaust fan inlet (negative pressure type) or pushes it directly to the outside (positive pressure type), avoiding the smoke from lingering indoors or spreading to the evacuation route.

[0021] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a first exhaust fan, the exhaust fan will horizontally exhaust the air from the indoor public restroom to the installation platform of the first air conditioner outdoor unit, so that it mixes with the air conditioner outdoor intake air, adjusts the intake air temperature, and improves the cooling efficiency of the air-cooled air conditioning unit, saves power consumption, and reduces operating costs and carbon emissions.

[0022] (2) By setting up a second exhaust fan, the air in the indoor office area is exhausted to the second air conditioner outdoor unit, so as to mix with the air conditioner outdoor intake and lower the intake air temperature.

[0023] (3) By setting up an indoor air supply component, the indoor air supply component can realize the orderly flow of indoor air, realize air supply, and ensure the freshness of indoor air. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this application will now be described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0031] Example 1 This application discloses an indoor exhaust system for an air-cooled air conditioner. (Refer to...) Figure 1 The ventilation system includes a roof structure 1, a first outdoor air conditioning unit 2, a first air conditioning duct 3, and a first exhaust fan 4. The first outdoor air conditioning unit 2 is installed on the roof structure 1, and the first air conditioning duct 3 is laid above the roof structure 1 and is used to supply air to the room from top to bottom. The first exhaust fan 4 is installed on the roof structure 1 and is close to the first outdoor air conditioning unit 2. The first exhaust fan 4 is connected to the indoor public restroom and is used to exhaust the air from the indoor public restroom to the periphery of the first outdoor air conditioning unit 2.

[0032] The exhaust air from the indoor public restroom is horizontally discharged to the mounting platform of the first outdoor air conditioning unit 2 via the first exhaust fan 4, mixing with the outdoor air intake of the air conditioner and adjusting the intake air temperature. By recycling and utilizing the indoor exhaust air, the cooling efficiency of the air-cooled air conditioning unit is improved, power consumption is saved, operating costs and carbon emissions are reduced, contributing to low-carbon development. It should be noted that alternatively, the air from the standard indoor public restroom can be first centrally discharged into the vertical shaft (not shown in the figure) of the main roof structure 1, and then guided through ducts to the intake environment of the first outdoor air conditioning unit 2, mixing with the outdoor air intake and adjusting the intake air temperature. The vertical shaft on the main roof structure 1 is a vertically penetrating channel structure in the building, typically extending from the ground floor to the roof, and can accommodate ventilation ducts.

[0033] Specifically, the ventilation system also includes a second outdoor air conditioning unit 5, a second air conditioning duct 6, and a second exhaust fan 7. The second outdoor air conditioning unit 5 is installed on the roof structure 1, and the second air conditioning duct 6 is laid above the roof structure 1 and is used to supply air to the room from top to bottom. The first air conditioning duct 3 and the second air conditioning duct 6 are symmetrically distributed on both sides of the roof structure 1, and the second exhaust fan 7 is close to the second outdoor air conditioning unit 5 and is used to exhaust the air in the indoor office area to the periphery of the second outdoor air conditioning unit 5.

[0034] The second exhaust fan 7 exhausts air from the indoor office area to the second outdoor air conditioning unit 5, mixing it with the outdoor intake air and adjusting the intake air temperature. Alternatively, the exhaust air from the total heat exchanger unit in the standard floor indoor office area can be centrally exhausted to a vertical shaft leading to the roof, and then led through ducts to the intake environment of the second outdoor air conditioning unit 5, mixing it with the outdoor intake air and adjusting the intake air temperature.

[0035] In this embodiment, the air outlets of both the first air conditioning duct 3 and the second air conditioning duct 6 are louvered exhaust vents. The blades of the louvers (which can be arranged horizontally or vertically) can guide the airflow direction through angle design (such as horizontal diffusion, oblique airflow, etc.), preventing the airflow from blowing directly onto the human body and reducing the discomfort of direct cold air blowing. In this embodiment, steel wire mesh (not shown in the figure) is fixedly installed at the inlet and outlet of both the first exhaust fan 4 and the second exhaust fan 7. The steel wire mesh has a certain strength and can protect the inlet and outlet frames, blades, and other components of the exhaust fan from external impacts; at the same time, the steel wire mesh can form a physical barrier, preventing the human body from directly contacting the rotating parts and reducing safety risks.

[0036] In addition, an indoor air supply assembly 8 and an indoor smoke exhaust assembly 9 are respectively installed on the roof main body 1. The indoor air supply assembly 8 is installed on the roof main body 1 and is used to supply air into the room. The indoor air supply assembly 8 includes an air supply duct 81 and a blower 82. The air supply duct 81 has a circular cross-section, with one end connected to the outside air and the other end connected to the room. The blower 82 is installed on the end of the air supply duct 81 near the room and is used to provide power to supply air into the room. Several sets of indoor air supply assemblies 8 are provided. In this embodiment, there are three sets of indoor air supply assemblies 8. The blower 82 drives the impeller to rotate at high speed through a motor. The rotation of the impeller generates centrifugal force or axial thrust and creates a pressure difference at the inlet and outlet of the blower 82. The airflow generated by the blower 82 is precisely guided to a designated position through the air supply duct 81 to avoid disorderly air diffusion.

[0037] The indoor smoke exhaust assembly 9 includes a smoke exhaust pipe 91 and a fire-fighting smoke exhaust fan 92. One end of the smoke exhaust pipe 91 is connected to the outside atmosphere, and the other end is connected to the interior. The fire-fighting smoke exhaust fan 92 is installed on the smoke exhaust pipe 91 and is used for smoke exhaust. In this embodiment, two sets of indoor smoke exhaust assemblies 9 are provided, and the two indoor smoke exhaust assemblies 9 are symmetrically distributed on both sides of the roof main body 1. When a fire occurs in the indoor building, the indoor smoke detector detects suspended particles in the smoke, transmits the signal to the smoke exhaust fan, and drives the smoke exhaust fan to operate. The negative pressure generated by the smoke exhaust fan is transmitted to the smoke exhaust outlet of the fire area through the smoke exhaust pipe 91, "drawing" the high-temperature smoke from the room, corridor and other spaces into the pipe; the smoke exhaust pipe 91 acts as a closed channel to directionally push the smoke to the outside, preventing the smoke from lingering indoors or spreading to evacuation routes, and ensuring the safety of people's lives.

[0038] The implementation principle of an indoor exhaust system for an air-cooled air conditioner according to an embodiment of this application is as follows: The first exhaust fan 4 horizontally exhausts the air from the indoor public restroom to the mounting platform of the first outdoor air conditioner unit 2, mixing it with the incoming outdoor air and adjusting the incoming air temperature. Similarly, the second exhaust fan 7 exhausts air from the indoor office area to the second outdoor air conditioner unit 5, mixing it with the incoming outdoor air and adjusting the incoming air temperature. By recycling and utilizing the indoor exhaust air, the cooling efficiency of the air-cooled air conditioning unit is improved, power consumption is saved, operating costs and carbon emissions are reduced, contributing to low-carbon development.

[0039] Example 2 Reference Figure 2 The difference between Embodiment 2 and Embodiment 1 lies in the structure of the air supply pipe 81. In this embodiment, the air supply pipe 81 is a square pipe, meaning its cross-section is rectangular. A pair of limiting plates 10 are fixedly installed inside the air supply pipe 81. The two limiting plates 10 are parallel to each other and have a gap. Air holes are provided on the two limiting plates 10 to allow air to pass through. Adsorbent material 11, which is activated carbon, is placed between the two limiting plates 10 to adsorb impurities in the air. A material inlet 12 is provided through the air supply pipe 81 for the adsorbent material to enter or exit, allowing workers to remove or insert the adsorbent material 11 between the two limiting plates 10. A first plate 13 and a second plate 14 are rotatably connected to the air supply pipe 81 via a torsion spring. The rotation axes of the first plate 13 and the second plate 14 are parallel, and they are interlocked together in a figure-eight shape. The first plate 13 and the second plate 14 are used to cover the material inlet 12, providing rain protection. The snap-fitting of the first plate 13 and the second plate 14 can be achieved by setting toothed grooves on the first plate and toothed blocks on the second plate.

[0040] The adsorbent 11 can remove impurities contained in the indoor air and improve the freshness of the air. When the adsorbent 11 needs to be replaced after long-term use, external force can be applied to the first plate 13 and the second plate 14 to remove the obstruction to the feed inlet 12, and then the adsorbent 11 can be replaced.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
