Description

Technical Field

[0001] This utility model relates to the field of fresh air systems, and in particular to a dual-cold-source fresh air conditioning unit. Background Technology

[0002] A fresh air conditioning unit is a device that combines a fresh air system and an air conditioning system, designed to provide fresh air indoors and regulate indoor temperature. It typically consists of a fresh air unit, an air conditioning unit, a blower, and filters. The fresh air system introduces fresh outdoor air into the room through the fresh air unit and removes dust, bacteria, and harmful substances from the air through the filters. This improves indoor air quality, eliminates indoor odors, and increases indoor oxygen levels.

[0003] A search revealed patent publication number CN216953376U, which discloses a combined environmentally friendly air conditioning fresh air unit. This combined unit includes: a housing; and a fresh air unit disposed inside the housing. A fixing component is provided on one side of the fresh air unit for fixing it. The fixing component includes: a fixing box fixedly connected to the housing; and a push rod slidably connected to the fixing box. A sliding groove is fixedly connected to the push rod; and a fixing strip slidably connected to the sliding groove. A fixing plate is rotatably connected to one side of the fixing strip; and a fixing head is fixedly connected to the fixing plate. A return spring is fixedly connected to one side of the push rod. This invention, by setting a limiting component, allows the device to cooperate with the fixing component, thereby ensuring the device's fixing ability while allowing for easy disassembly of the air conditioning fresh air unit, making it more suitable for widespread use.

[0004] A search revealed patent publication number CN220205903U, which discloses a centralized air conditioning fresh air handling unit. This unit includes a supply air duct and an exhaust air duct, as well as a heat exchange filter element for exchanging heat between the supply and exhaust air. The supply air duct contains a heat exchange sub-duct and a bypass sub-duct. The main body of the heat exchange filter element is located in the heat exchange sub-duct, with its inlet and outlet located in the exhaust air duct. A supply air bypass valve is installed in the bypass sub-duct to control its opening and closing. An exhaust air bypass valve is installed in the exhaust air duct, positioned between the inlet and outlet of the heat exchange filter element, allowing direct connection between them when the exhaust air bypass valve is open. This centralized air conditioning fresh air handling unit, by adding fresh air and exhaust air bypass valves and opening the bypass valves during transitional seasons, reduces air resistance and lowers system energy consumption.

[0005] While existing technologies can achieve certain usage modes of fresh air systems, they have drawbacks: existing dual-source fresh air conditioning units lack multi-layer heating and multi-level air conditioning effects, resulting in the inability to effectively regulate the air exchange speed in large indoor spaces, and the air heating effect is unstable, easily leading to large temperature deviations. In view of this, we propose a dual-source fresh air conditioning unit that solves the above problems. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a dual-cold-source fresh air conditioning unit.

[0007] The technical solution of this utility model is as follows: A dual-cold-source fresh air conditioning unit includes a housing. The housing contains a primary filter section, a primary heating section on one side of the primary filter section, a secondary heating section on one side of the primary heating section, a fan assembly on one side of the secondary heating section, and a humidification section on one side of the fan assembly. The humidification section contains an installation groove.

[0008] Working Principle: This device utilizes both the return air inlet and the inlet air outlet for air intake. The incoming air undergoes primary heating, evaporation, water blocking, and secondary heating sequentially. Then, it is rapidly propelled through the humidification section by fans one and two, and finally passes through a medium-efficiency filter before being discharged through the outlet and vent. The discharged air is heated and moistened, not dry, contributing to air exchange and a comfortable, ergonomic feel in large indoor spaces. A key feature of this device is its dual-layer heating system, which achieves uniform and stable air heating. Furthermore, the circling design of fans one and two allows for switching between high-speed and low-speed airflow, enhancing the user experience and making it highly practical.

[0009] Preferably, an evaporation section is provided between the primary heating section and the secondary heating section, and a water-blocking section is provided on one side of the evaporation section. The evaporation section is mainly used for cooling and dehumidifying the air. It absorbs heat from the air through the evaporation of refrigerant, thereby lowering the air temperature. When the air temperature drops below the dew point temperature, the water vapor in it will condense into water droplets, thus achieving the dehumidification effect.

[0010] Preferably, a fan 1 is provided in the center of the fan assembly surface, and a fan 2 is provided in a square array around the fan 1. A motor 1 and a motor 2 are fixed on one side of the fan assembly. The output shaft of the motor 1 is fixedly connected to the rotation center of one side of the fan 1, and the output shaft of the motor 2 is fixedly connected to the rotation center of one side of the fan 2. The fan 1 is larger in size and occupies most of the position.

[0011] Preferably, a fresh air inlet is provided on one side of the outer wall of the box, an air supply inlet is provided on the other side of the outer wall of the box, a return air inlet is provided on one side of the upper end of the box, and an air outlet is provided on the other side of the upper end of the box. The fresh air inlet is the location where fresh air enters. In conjunction with the air supply inlet, the synthesized air can be processed and then discharged from the air outlet or the air supply inlet.

[0012] Preferably, a medium-efficiency filter section is provided on one side of the humidification section, and a humidity sensor is fixed on the outer wall of one side of the humidification section. The medium-efficiency filter section can further filter the air based on the primary filter section. The humidity sensor can detect the humidification effect of the humidification section and provide backend data for effective adjustment.

[0013] Preferably, the mounting groove is equipped with a water tank, and a water pump is installed at the upper end of the water tank. A control circuit is fixed at the upper end of the water pump. The humidification section is mainly a wet film humidifier. The wet film is the core component and is made of plant fiber or glass fiber with added special chemical components. It has excellent water absorption and evaporation characteristics.

[0014] Preferably, the outer walls on both sides of the mounting groove are provided with heat dissipation mesh. The upper end of the heat dissipation mesh is flush with the control circuit, and the lower end is flush with the bottom of the water tank. The heat dissipation mesh can effectively dissipate heat from the water pump and control circuit when the air flows.

[0015] Preferably, a base is fixed at the lower end of the housing, and a temperature-regulating water inlet and outlet pipe is provided at the rear end of the housing. A condensate outlet pipe is provided diagonally below the temperature-regulating water inlet and outlet pipe. The base can increase the stability of the device. The temperature-regulating water inlet and outlet pipe and the condensate outlet pipe are connected to corresponding parts inside the device.

[0016] Preferably, the rear middle of the housing is provided with a pair of outdoor unit inlet / outlet copper pipes and chilled water inlet / outlet pipes, which can be connected to the indoor unit to achieve pipeline access.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] I. This utility model can utilize the design of primary heating and secondary heating in the front and rear bands of air treatment in the middle of the box, respectively. The heating time is short and fixed each time, which makes the heating efficiency uniform and can achieve good air filtration, heating and humidification effect.

[0019] Second, based on the first beneficial effect, this device can utilize the design of fan two surrounding fan one. The airflow speed of fan two is less than that of fan one. When a large airflow is needed, fan one is turned on. When there is normal airflow, fan two is kept on continuously, resulting in a stable air supply effect.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Please see Figures 1-5 As shown, this embodiment is a dual-source fresh air conditioning unit, including a housing 1. The housing 1 has a primary filter section 11 inside, a primary heating section 28 on one side of the primary filter section 11, a secondary heating section 14 on one side of the primary heating section 28, a fan assembly 18 on one side of the secondary heating section 14, a humidification section 17 on one side of the fan assembly 18, and an installation groove 19 inside the humidification section 17.

[0034] Working Principle: This device utilizes the return air inlet 2 and the air inlet for air intake. The incoming air undergoes primary heating, evaporation, water blocking, and secondary heating sequentially. Then, it is rapidly propelled through the humidification section 17 by the accelerated blowing of fans 27 and 26. Finally, it passes through a medium-efficiency filter before being discharged from the outlet 5 and the supply air outlet 6. The discharged air is heated and moistened, contributing to air exchange and a comfortable, ergonomic feel in large indoor spaces. The device features a dual-layer heating effect for uniform and stable air heating. Furthermore, the circling design of fans 27 and 26 allows for switching between high-speed and low-speed airflow, enhancing the user experience and making it highly practical.

[0035] Example 2

[0036] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: an evaporation section 12 between the primary heating section 28 and the secondary heating section 14, and a water-blocking section 13 on one side of the evaporation section 12. The evaporation section 12 is mainly used for cooling and dehumidifying the air. It absorbs heat from the air through the evaporation of refrigerant, thereby lowering the air temperature. When the air temperature drops below the dew point temperature, the water vapor in it will condense into water droplets, thus achieving the dehumidification effect.

[0037] The function of the water-blocking section 13 is to block condensation carried in the air being treated. After the air is cooled by the evaporation section 12, it may carry some condensation. The water-blocking section 13 can prevent these water droplets from being carried into the subsequent air supply ducts and rooms, avoiding adverse effects on the indoor environment, such as wetting the ceiling and walls.

[0038] A fan 27 is located in the center of the surface of the fan assembly 18. Fans 26 arranged in a square array are located around the fan 27.

The output shaft of motor 26 is fixedly connected to the rotation center of one side of fan 26. Fan 27 is large in size and occupies most of the space. As the main power output source, when it is necessary to enhance the internal airflow, fan 27 can be started. When it is not necessary to speed up the flow, fan 26 can simply maintain the normal flow speed.

[0039] A fresh air inlet 3 is provided on one side of the outer wall of the housing 1, and an air supply outlet 6 is provided on the other side of the outer wall of the housing 1. A return air inlet 2 is provided on one side of the upper end of the housing 1, and an air outlet 5 is provided on the other side of the upper end of the housing 1.

The medium-efficiency filter section 20 can further filter the air based on the primary filter section 11. The humidity sensor 25 can detect the humidification effect of the humidification section 17 and provide backend data for effective adjustment.

[0042] The mounting slot 19 contains a water tank 24, and a water pump 21 is mounted on the upper end of the water tank 24. A control circuit 22 is fixed on the upper end of the water pump 21. The humidification section 17 is mainly a wet film humidifier. The wet film is the core component, made of plant fiber or glass fiber with added special chemical components, which has excellent water absorption and evaporation characteristics. The water tank 24 can store water to provide a water source for the wet film. Some sections are equipped with inlets, outlets, overflow outlets, etc. The water pump 21 delivers the water in the water tank 24 to the water sprayer on top of the wet film, so that the water is evenly distributed on the wet film. The control circuit 22 can automatically control the start and stop of the humidifier and the operation of the water pump 21 and other equipment according to the set humidity value.

[0043] Heat dissipation mesh 23 is provided on the outer walls of both sides of the mounting slot 19. The upper end of the heat dissipation mesh 23 is flush with the control circuit 22, and the lower end is flush with the bottom of the water tank 24. The heat dissipation mesh 23 can effectively dissipate heat from the water pump 21 and the control circuit 22 when the air flows.

[0044] A base 4 is fixed at the lower end of the housing 1. A temperature-regulating water inlet and outlet pipe 7 is provided at the rear end of the housing 1. A condensate outlet pipe 10 is provided diagonally below the temperature-regulating water inlet and outlet pipe 7. The base 4 can increase the stability of the device. The temperature-regulating water inlet and outlet pipe 7 and the condensate outlet pipe 10 are connected to the corresponding parts inside the device.
