Description

Technical Field

[0001] This application relates to the field of horizontal fan coil technology, and more particularly to a ceiling-mounted horizontal fan coil. Background Technology

[0002] In modern building environmental control systems, ceiling-mounted horizontal fan coil units, as core terminal equipment of HVAC systems, are widely used in diverse building spaces such as commercial office buildings, hotel rooms, and high-end residences due to their advantages such as high-efficiency heat exchange and space saving. They achieve indoor temperature regulation through heat exchange between circulating air and refrigerant, playing a crucial role in creating a comfortable indoor environment.

[0003] However, existing traditional ceiling-mounted horizontal fan coil units still face many technical bottlenecks that urgently need to be addressed in their design and application.

[0004] 1. In terms of appearance design, its assembly structure mostly uses exposed screws for fixing, which not only destroys the overall aesthetics of the building space, but also makes the screws prone to oxidation and corrosion during long-term use, affecting the stability of the equipment.

[0005] 2. In terms of inspection and maintenance, the unreasonable placement of the inspection port restricts the operating space for maintenance personnel when replacing filters and repairing components, significantly increasing the difficulty and time cost of maintenance.

[0006] 3. In terms of heat exchange performance, the design flaws of the condenser 300 heat dissipation channel result in poor air circulation, low heat dissipation efficiency, and energy waste.

[0007] 4. In terms of airflow organization, the unreasonable structure of the air outlet and the layout of the air duct result in uneven distribution of indoor airflow, causing problems such as large local temperature differences and strong blowing sensation, which seriously affects the user's thermal comfort experience.

[0008] The aforementioned problems not only hinder the performance improvement and market promotion of ceiling-mounted horizontal fan coil units, but also result in high maintenance costs throughout the equipment's life cycle.

[0009] Therefore, there is an urgent need to design a new type of ceiling-mounted horizontal fan coil unit. Through structural optimization and technological innovation, it is possible to effectively solve the technical problems of traditional equipment, such as appearance, maintenance, heat dissipation, and airflow distribution, so as to meet the urgent needs of modern buildings for efficient, comfortable, and convenient air handling equipment.

[0066] Please see Figures 1 to 10 This utility model discloses a ceiling-mounted horizontal fan coil unit, including a fan coil unit body 100, a fresh air inlet 200, a condenser 300, an inspection port 104, and a baffle plate 500.

[0067] The fan coil unit 100 is used to connect to the ceiling. The fan coil unit 100 adopts a screwless assembly structure to ensure that there are no exposed external screws on the appearance of the fan coil unit 100, thereby improving the aesthetics of the device.

[0068] Specifically, the fan body 100 may include a top panel 110 and a side panel 120 disposed around the periphery of the top panel 110. The side panel 120 and the top panel 110 are integrally formed and / or connected by snap-fit.

[0069] In one embodiment, the side panel 120 may include a left panel 121, a right panel 122, a front panel 123, and a rear panel 124. Along the airflow direction, the front panel 123 is positioned in front of the airflow, and the rear panel is positioned behind the airflow. The left panel 121 and right panel 122 are located on opposite sides of the airflow direction, and their ends are connected to the front panel 123 and rear panel 124, respectively.

[0070] Specifically, the left panel 121 and the right panel 122 can be integrally formed with the top panel 110, and the front panel 123 and the rear panel 124 can be snapped together with the top panel 110, the left panel 121, and the right panel 122.

[0071] Furthermore, injection molding technology can be used in the one-piece molding process of the left panel 121, right panel 122, and top panel 110. This effectively eliminates seams and screw holes, giving the fan coil unit a smooth, seamless visual effect, greatly enhancing the product's aesthetics and texture. Simultaneously, the one-piece molding structure also strengthens the overall rigidity of the fan coil unit 100, reducing noise caused by vibration.

[0072] Furthermore, the snap-fit ​​connection between the front panel 123 and the rear panel 124 and the top panel 110, left panel 121, and right panel 122, respectively, can be achieved using a snap-fit ​​connection method. Specifically, an inwardly recessed groove can be provided on the edge of the top panel 110, and outwardly protruding blocks can be designed on the corresponding positions of the front panel 123 and the rear panel 124, allowing the blocks to engage tightly with the groove. During installation, aligning the blocks of the side panel 120 with the grooves of the top panel 110 and applying moderate pressure completes the installation, making the operation simple and quick. In addition, the snap-fit ​​structure can also adopt a multi-snap-fit ​​combination, distributing multiple snap-fit ​​points at different positions on the side panel 120 to evenly distribute the force and ensure the reliability of the connection.

[0073] In one embodiment, the fresh air inlet 200 is integrated into the side of the fan coil unit 100, and an airflow regulating valve for adjusting the air volume is connected to the fresh air inlet 200. Through the airflow regulating valve, the airflow rate entering the fan coil unit 100 can be flexibly adjusted according to actual needs, meeting the ventilation and air handling requirements under different environments and operating conditions, significantly improving the applicability and flexibility of the device.

[0074] It should be noted that an air inlet 101 and an air outlet 102 are provided on the side panel 120, and the air inlet 101 and air outlet 102 are arranged opposite each other. The fresh air inlet 200 is located on the same side of the side panel 120 as the air inlet 101. Therefore, it is possible for fresh air to enter the fan coil unit 100 efficiently, be processed internally, and then be discharged in an orderly manner, ensuring smooth air circulation and improving air handling efficiency and effect.

[0075] In one embodiment, the fresh air inlet 200 and the air intake 101 are located on the rear panel 124, and the air outlet 102 is located on the front panel 123. Therefore, after the fresh airflow enters the interior of the fan coil body 100 through the air intake 101 and / or the fresh air inlet 200, it is processed inside the fan coil body 100 and then discharged through the air outlet 102.

[0076] In one embodiment, an access port 104 is provided at the bottom of the fan coil body 100, and an access plate 103 for covering the access port 104 is pivotally connected to the fan coil body 100 at the access port 104. Specifically, one side of the access plate 103 is pivotally connected to the fan coil body 100 via a hinge, and the other side of the access plate 103 is detachably fixedly connected to the fan coil body 100 via a snap-fit ​​mechanism 105.

[0077] The snap-fit ​​mechanism 105 can be determined according to actual needs. For example, in one embodiment, the snap-fit ​​mechanism 105 may include a snap-fit ​​connector 1051 disposed on the edge of the inspection plate 103 and a snap-fit ​​hole 1052 formed on the side surface of the fan body 100. When the inspection plate 103 is rotated by the hinge and covers the inspection port 104, the snap-fit ​​connector 1051 can snap onto the snap-fit ​​hole 1052.

[0078] Therefore, by opening an inspection port 104 at the bottom of the fan coil unit 100, it is easy to quickly locate and solve problems, such as replacing the filter and checking the circuit, which greatly reduces the difficulty and cost of maintenance. At the same time, the inspection plate 103 is connected by a movable hinge, ensuring that the opening and closing process is smooth and stable, and it can be easily operated without tools, which facilitates daily inspection and emergency maintenance.

[0079] In one embodiment, a mounting bracket 130 may also be provided inside the fan coil body 100, which is detachably connected to the fan coil body 100. The mounting bracket 130 is provided with a connecting panel 1301, and a fan 131, a baffle plate 132, a guide plate 500, and a condenser 300 are arranged sequentially on the connecting panel 1301. The baffle plate 132 has a first opening 1320, and the air outlet 102 of the fan 131 is connected to the first opening 1320.

[0080] Furthermore, a mounting strip 106 can be fixedly connected to the top of the fan body 100, and a snap-fit ​​interface 1061 is provided on the mounting strip 106. A snap-fit ​​block 1602 corresponding to the snap-fit ​​interface 1061 is provided on the mounting bracket 130, and the snap-fit ​​block 1602 and the snap-fit ​​interface 1061 snap together. By adopting a detachable connection method for the mounting bracket 130, the ease and flexibility of equipment maintenance are greatly improved, making it convenient for users to inspect, replace, or upgrade components such as the fan 131 and the baffle 132, reducing maintenance costs while extending the service life of the equipment.

[0081] Furthermore, the wind deflector 132 includes a main body 1321 and extensions 1322 located on both sides of the main body 1321. The extensions 1322 are set at an angle to the main body 1321, and the extensions 1322 extend and connect to the mounting bracket 130. The angled structure between the main body 1321 and the extensions 1322 of the wind deflector 132 effectively enhances structural stability, thereby reducing vibration and noise during equipment operation.

[0082] The baffle 132 and the guide plate 500 are spaced apart. Together with the connection between the air outlet 102 of the fan 131 and the first opening 1320 of the baffle 132, they form an airflow guiding path, so that the airflow accelerated by the fan 131 can pass through the gap in an orderly manner, thereby improving the airflow efficiency.

[0083] Furthermore, the guide vane 500 is located in the airflow channel within the fan body 100, and the surface of the guide vane 500 has multiple through holes 501, the distribution density of which varies gradually along the airflow direction. This gradient design of the density of through holes 501 on the surface of the guide vane 500 along the airflow direction enables precise control of airflow speed and flow distribution, achieving efficient air processing and optimizing air output quality.

[0084] It is important to note that the condenser 300 is located within the positive pressure zone inside the fan coil unit 100. The positive pressure zone represents the area of ​​relatively high pressure formed after the airflow is pressurized by the fan 131. The high-speed airflow in the positive pressure zone enhances heat transfer between the condenser 300 and the air, allowing the refrigerant within the condenser 300 to complete heat exchange more quickly and efficiently, thereby improving cooling performance. Simultaneously, the stable airflow environment in the positive pressure zone effectively reduces vibrations in the condenser 300 caused by airflow fluctuations, reducing mechanical wear, extending the service life of the condenser 300, reducing equipment failure rates, ensuring long-term stable operation of the equipment, and lowering subsequent maintenance costs.

[0085] Furthermore, the airflow characteristics of the positive pressure zone also help to quickly remove the heat generated by the condenser 300 during operation, preventing it from getting too hot, maintaining the efficient heat exchange performance of the condenser 300, and preventing performance degradation due to overheating.

[0086] Based on this, the coordinated operation of the condenser 300 with the fan 131, the baffle 132, and the guide plate 500 can effectively optimize the airflow circulation path within the entire fan coil unit 100.

[0087] In one embodiment, the ceiling-mounted horizontal fan coil unit disclosed in this utility model further includes a processor mounting box 600, which is slidably connected to the mounting bracket 130. Specifically, a second opening 1302 is allowed to be formed on the connecting panel 1301, and the processor mounting box 600 is located within the opening area of ​​the second opening 1302. Therefore, in actual maintenance, it is permissible to remove the processor mounting box 600 from the mounting bracket 130 without disassembling the mounting bracket 130.

[0088] In one embodiment, the ceiling-mounted horizontal fan coil unit disclosed in this utility model further includes a cleaning component 700. The cleaning component 700 is located in the airflow path, disposed between the fresh air inlet 200 and the fan 131, and connected to the fan coil unit body 100. The cleaning component 700 can clean the gas entering the fan coil unit body 100.

[0089] Specifically, the cleaning assembly 700 includes a first filter plate 710, a second filter plate 720, and a disinfection lamp 730 arranged sequentially along the airflow direction. The first filter plate 710 performs primary filtration of the gas, and the second filter plate 720 performs advanced filtration. Finally, the gas is disinfected by the disinfection lamp 730, which can greatly improve the safety performance of the gas.

[0090] In summary, this utility model provides a ceiling-mounted horizontal fan coil unit. The fan coil body 100 utilizes a screwless assembly structure, combining integrated molding and snap-fit ​​connection technology to eliminate external screws and seams, effectively improving product aesthetics, enhancing overall rigidity, and reducing operating noise. Secondly, by constructing an efficient airflow circulation path, air handling efficiency is ensured. An inspection port 104 located at the bottom of the fan coil unit, along with hinges and a snap-fit ​​mechanism 105, facilitates convenient and efficient maintenance operations such as filter replacement and circuit checks, reducing maintenance costs and difficulty.

[0091] By designing the through holes 501 of the guide plate 500 with a gradient distribution, airflow guidance can be effectively optimized, and airflow speed and flow rate can be precisely controlled to achieve efficient air handling. Furthermore, by placing the condenser 300 in a positive pressure zone, high-speed and stable airflow is used to enhance heat exchange, improve cooling (heating) performance, reduce vibration and wear, and extend equipment life.

[0092] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
