Description

Technical Field

[0001] This invention relates to the field of fresh air conditioning technology, specifically to an outdoor building-integrated fresh air conditioning system. Background Technology

[0002] A fresh air conditioning system is a device that combines a fresh air system and an air conditioning system. It can exchange indoor and outdoor air and purify indoor air. The use of fresh air conditioning systems can improve indoor air quality and enhance the comfort of residents. However, fresh air conditioning systems require structural modifications to match the shape and style of various buildings, making mass production difficult and costly. Furthermore, many existing fresh air conditioning systems require additional independent channels and fans to draw in fresh air, further increasing costs. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an outdoor building-integrated fresh air conditioning system, which solves the problems mentioned in the background section.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an outdoor building-integrated fresh air air conditioner, comprising a building body and an air conditioner housing. A partition is installed inside the air conditioner housing, dividing the interior into an indoor cavity and an outdoor cavity. An indoor return air filter inlet is located at the lower part of the indoor cavity near the building body, and a fresh air intake filter inlet is located at the upper part of the indoor cavity near the building body. An indoor air supply vent is located at the top of the indoor cavity. Outdoor air inlets are located on both sides of the outdoor cavity, and an outdoor air outlet is located on the side of the outdoor cavity furthest from the building body. An evaporator is installed inside the return air filter inlet, and a sliding fresh air control plate is installed outside the fresh air intake filter inlet. A fan is installed below the indoor air supply outlet. An air supply grille is installed above the indoor air supply outlet on the main building. A condenser is installed inside the outdoor air intake filter inlet. An outdoor fan is installed inside the outdoor air outlet. A compressor is installed on one side inside the outdoor cavity. A contoured fresh air sleeve is installed between the main building and the air conditioning casing. Fresh air inlets are opened on both sides of the contoured fresh air sleeve. An air baffle is installed inside the contoured fresh air sleeve. An air supply sleeve is installed between the air supply grille and the indoor air supply outlet.

[0005] Preferably, one end of the fresh air control panel is equipped with an electric cylinder. The telescopic rod of the electric cylinder is connected to the fresh air control panel. When the electric cylinder is working, it can push the fresh air control panel to slide left and right. The fresh air control panel and the air conditioner housing behind it are both provided with through holes of the same shape. When the through holes of the two are aligned, air can pass through the fresh air control panel and enter the indoor cavity. Conversely, when the through holes of the two are completely misaligned, the fresh air control panel can block air from entering the indoor cavity.

[0006] Preferably, the building body has mesh openings near both the indoor return air filter inlet and the indoor air supply outlet, allowing the interior of the building body to be connected to the indoor cavity through the two mesh openings.

[0007] Preferably, both the evaporator and the condenser are connected to the compressor via copper pipes. A four-way valve and an electronic expansion valve are installed on the copper pipes. When the compressor is working, the evaporator can be heated and the condenser can be cooled, or the evaporator can be cooled and the condenser can be heated, by adjusting the four-way valve and the electronic expansion valve.

[0008] Preferably, when the fan is working, it draws air from inside the building into the indoor cavity through the indoor return air filter and discharges it back into the building through the indoor air supply outlet, forming an air circulation. During this process, if the evaporator is at a high temperature, the air temperature inside the building will rise; if the evaporator is at a low temperature, the air temperature inside the building will decrease. At the same time, outdoor air is also drawn into the indoor cavity by the fan from the fresh air inlet, adding to the air circulation and achieving the effect of replacing indoor air.

[0009] Preferably, when the outdoor fan is working, it draws outdoor air into the outdoor cavity from the outdoor air inlet filter and discharges it from the outdoor air outlet. At this time, the circulating air passes through the condenser. During this process, the heat or cold energy of the condenser is carried away by the circulating air, so that the compressor can carry out effective energy conversion continuously.

[0010] Preferably, the connection between the contoured fresh air sleeve and the building body and the air conditioner casing is sealed and airtight, the connection between the air supply sleeve and the air supply grille and the indoor air supply outlet is sealed and airtight, and the air-insulating sleeve divides the interior of the contoured fresh air sleeve into two layers of air ducts that do not communicate with each other. The outer air duct is used for fresh air intake, and the inner air duct is used for indoor air circulation.

[0011] (III) Beneficial Effects This invention provides an outdoor building-integrated fresh air air conditioner, which has the following beneficial effects: 1. This outdoor building integrated fresh air air conditioner, through the combined setting of the contoured fresh air sleeve and the air supply sleeve, not only can it be easily matched with various types of buildings, but it can also be mass-produced to reduce costs. The air duct between the building and the air conditioner is connected by the simple contoured fresh air sleeve and the air supply sleeve. Therefore, no matter how the appearance shape of the building changes, the structure of the air conditioner can remain unchanged. Only the contoured fresh air sleeve and the air supply sleeve need to be changed, which makes the air conditioner easy to mass-produce and reduce costs.

[0012] 2. This outdoor integrated building fresh air conditioner, through the coordinated design of the air conditioner casing, fresh air control panel, and contoured fresh air sleeve, achieves low manufacturing cost for its fresh air intake control structure and significant indoor temperature and humidity regulation. The indoor return air filter and the fresh air intake filter are placed close together and near the same impeller. An electric cylinder drives the fresh air control panel to change the opening and closing size of the fresh air intake filter. This allows for simultaneous extraction of indoor and outdoor air into the air conditioner and control of the fresh air intake volume using only one impeller and one electric cylinder. The contoured fresh air sleeve not only serves as a connecting structure but also functions as two air ducts, making it highly cost-effective. Since no separate air duct is required, costs are reduced, and the airflow between the fresh air intake channel and the indoor return air circulation channel is excellent. This allows for rapid response to temperature and humidity adjustments with minimal energy loss, resulting in significant indoor temperature and humidity regulation. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] Please see Figures 1 to 5This invention provides a technical solution: an outdoor building integrated fresh air air conditioner, including a building body 1 and an air conditioner housing 2. A partition 201 is installed inside the air conditioner housing 2, dividing the interior of the housing 2 into an indoor cavity 202 and an outdoor cavity 203. An indoor return air filter 204 is provided on the lower part of the indoor cavity 202 near the building body 1, and a fresh air intake filter 205 is provided on the upper part of the indoor cavity 202 near the building body 1. An indoor air supply vent 206 is provided at the top of the indoor cavity 202. Outdoor air intake filter vents 207 are provided on both sides of the outdoor cavity 203, and an outdoor air outlet vent 208 is provided on the side of the outdoor cavity 203 away from the building body 1. The building body 1 is located near the indoor return air filter 204 and... The indoor air supply vents 206 are all perforated, allowing the interior of the main building 1 to connect with the indoor cavity 202 through two perforations. An evaporator 3 is installed inside the indoor return air filter vent 204, and a sliding fresh air control plate 4 is installed outside the fresh air intake filter vent 205. An electric cylinder 12 is installed at one end of the fresh air control plate 4, and the extension rod of the electric cylinder 12 is connected to the fresh air control plate 4. When the electric cylinder 12 is working, it can push the fresh air control plate 4 to slide left and right. The fresh air control plate 4 and the air conditioning housing 2 behind it both have through holes of the same shape. When the through holes are aligned, air can pass through the fresh air control plate 4 into the indoor cavity 202; conversely, when the through holes are completely misaligned, the fresh air control plate 4 can block air from entering the indoor cavity 202. A fan wheel 5 is installed below the air vent 206. An air supply grille 6 is installed above the indoor air supply vent 206 on the main building 1. A condenser 7 is installed inside the outdoor air inlet filter 207. An outdoor fan 8 is installed inside the outdoor air outlet 208. A compressor 9 is installed on one side inside the outdoor cavity 203. The evaporator 3 and the condenser 7 are both connected to the compressor 9 through copper pipes. A four-way valve 13 and an electronic expansion valve 14 are installed on the copper pipes. When the compressor 9 is working, the evaporator 3 can be heated and the condenser 7 can be cooled or cooled and heated respectively by adjusting the four-way valve 13 and the electronic expansion valve 14. When the outdoor fan 8 is working, outdoor air is drawn into the outdoor cavity 203 from the outdoor air inlet filter 207 and discharged from the outdoor air outlet 208. At this time, the circulating air passes through the condenser 7. During this process, the heat or cold energy of the condenser 7 is carried away by the circulating air, allowing the compressor 9 to continuously and effectively perform energy conversion. A contoured fresh air sleeve 10 is installed between the building body 1 and the air conditioner casing 2. Fresh air inlets 1001 are opened on both sides of the contoured fresh air sleeve 10. An air-insulating sleeve 1002 is installed inside the contoured fresh air sleeve 10. When the fan wheel 5 is working, it draws the air inside the building body 1 from the indoor return air filter port 204 into the indoor cavity 202 and discharges it back to the building body 1 from the indoor air supply port 206, forming an air circulation. During this process, if the evaporator 3 is in a high-temperature state, the air temperature inside the building body 1 will rise; if the evaporator 3 is in a low-temperature state, the air temperature inside the building body 1 will decrease.In this fresh air conditioner, the evaporator and condenser exchange their outer surface temperatures during cooling and heating, thus alternating their respective effects. Simultaneously, outdoor air is drawn from the fresh air inlet 1001 into the indoor cavity 202 by the fan wheel 5, incorporating air circulation to replace indoor air. An air supply sleeve 11 is installed between the air supply grille 6 and the indoor air supply outlet 206. The connection between the contoured fresh air sleeve 10 and the building structure 1 and the air conditioner casing 2 is airtight. The air supply sleeve 11, the air supply grille 6, and the indoor air supply outlet 206 are also airtight. The air-insulating sleeve 1002 divides the interior of the contoured fresh air sleeve 10 into two non-interconnected air ducts: the outer duct for fresh air intake and the inner duct for indoor air circulation.

[0017] When in use, the air conditioner manufacturer does not need to consider the installation conditions proposed by the customer. The air conditioner and the air supply grille 6 can be mass-produced and stored in the warehouse. Due to mass production, the production cost can be greatly reduced. When a customer places an order for the air conditioner, the contoured fresh air sleeve 10 and air supply sleeve 11 are made according to the appearance shape of the main building 1 and the air inlet and outlet. The air conditioner is then connected to the building through the contoured fresh air sleeve 10 and air supply sleeve 11. Therefore, even if the appearance shape of the building changes, the structure of the air conditioner does not need to be changed. Because the structure of the contoured fresh air sleeve 10 and air supply sleeve 11 is very simple, the production speed is very fast and the appearance can be easily changed to perfectly connect with the building. For example, if the shape of the starry sky house is curved, one side of the contoured fresh air sleeve 10 can be made to be curved like the starry sky house, making the installation of the air conditioner more aesthetically pleasing. During operation, the fresh air control plate is pushed by the electric cylinder 12 to control the amount of fresh air drawn in. Specifically, the fresh air control plate and the air conditioner housing 2 behind it both have through holes of the same shape. When the through holes of the two are aligned, air can pass through the fresh air control plate and enter the indoor cavity 202. Conversely, when the through holes of the two are completely misaligned, the fresh air control plate can block air from entering the indoor cavity 202. In ventilation mode, the fresh air control plate and the through holes of the air conditioner housing 2 behind it are completely aligned. Then, the fan wheel 5 rotates to draw outdoor air into the room from the fresh air inlet 1001. In heating or cooling mode, the distance that the fresh air control plate slides is pushed by the electric cylinder 12 to change the alignment of the fresh air control plate and the through holes of the air conditioner housing 2 behind it, thereby changing the flow rate of fresh air drawn in to participate in indoor air circulation when the air conditioner is heating or cooling, so as to realize indoor air exchange while the air conditioner is heating or cooling.

[0018] In summary, this outdoor building-integrated fresh air conditioning system connects the building and the air conditioner through a simple contoured fresh air sleeve 10 and air supply sleeve 11. Therefore, even if the building's exterior shape changes, the air conditioner's structure remains unchanged; only the contoured fresh air sleeve 10 and air supply sleeve 11 need to be modified. This facilitates mass production and reduces costs. The indoor return air filter 204 and the fresh air intake filter are placed close together and near the same impeller 5. An electric cylinder 12 drives a fresh air control plate to change the opening and closing of the fresh air intake filter. This allows for simultaneous extraction of indoor and outdoor air into the air conditioner and control of the fresh air intake volume using only one impeller 5 and one electric cylinder 12. The contoured fresh air sleeve 10 serves not only as a connecting structure but also as two air ducts, making it highly cost-effective. Since a separate air duct is not required, costs are reduced. It also ensures good airflow between the fresh air intake channel and the indoor return air circulation channel, enabling rapid response to temperature and humidity adjustments with minimal energy loss, thus achieving significant indoor temperature and humidity control.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
