Description

Technical Field

[0001] This utility model relates to an air conditioning system, specifically, to a multi-functional independent micro air conditioning system. Background Technology

[0002] Currently, buses and coaches are common forms of public transportation. For safe driving, the driver's driving environment is a crucial factor affecting driving safety. As people's demands for buses and driving environments continue to increase, bus air conditioning systems also need to be upgraded. In particular, the driver's seat needs to be equipped with an independent air conditioning system capable of cooling, heating, and fresh air exchange. In addition, many special vehicles, such as military vehicles and blood donation vehicles, also have independent driver's cabins and require air conditioning systems to regulate the driving environment.

[0003] To meet the above requirements, existing technology adds a single cooler interface to the traditional bus air conditioner, which, together with the air duct, delivers cold and hot air to the driver's compartment. However, it has a single function, cannot achieve same-side air intake and exhaust, and does not have a fresh air function. Utility Model Content

[0004] The technical problem this invention aims to solve is: how to design a multifunctional independent small air conditioning system that can not only achieve air conditioning cooling and heating functions, but also achieve same-side air intake and exhaust. Simultaneously, the addition of a fresh air function can improve ventilation efficiency and enhance the air quality inside the vehicle.

[0005] To solve the above problems, this utility model is achieved through the following technical solution: A multifunctional independent micro air conditioning system includes an air conditioning shell, and a cold core assembly and a warm core assembly are arranged inside the air conditioning shell. The cold core assembly is connected to a cold core air inlet and liquid outlet pipeline assembly, and the warm core assembly is connected to a warm core water inlet and outlet pipeline assembly. The interfaces of the cold core air inlet and liquid outlet pipeline assembly and the warm core water inlet and outlet pipeline assembly are all located on the same side. There are two sets of through holes on the outer side of the air conditioner casing, namely the air outlet and the air inlet, which are located on the same side of the air conditioner casing. Inside the air conditioner casing, there is also a fan assembly, which is fixed between the cooling core assembly and the heating core assembly by a fan mounting bracket.

[0006] The through-hole structure of the air outlet and air inlet is rectangular or circular.

[0007] Multiple mounting brackets are installed around the air conditioner casing, and the mounting brackets are fixedly connected to the air conditioner casing.

[0008] Add a deflector plate to the air inlet of the fan assembly.

[0009] A water box assembly is provided at the bottom of the cold core assembly and the warm core assembly. The water box assembly is fixed to the air conditioner casing and is connected to the water pipe.

[0010] A fresh air inlet is added to the side panel on the other side of the air conditioner casing. A fresh air actuator assembly is provided at the rear end of the air duct of the fresh air inlet. The fresh air actuator assembly includes a fresh air actuator. The output shaft of the fresh air actuator is connected to the left fixed shaft and the right fixed shaft through a coupling. A fresh air baffle is fixed between the left fixed shaft and the right fixed shaft by bolts.

[0011] The right fixed shaft is also connected to a rotating handle.

[0012] An upper water-blocking plate and a lower water-blocking plate are fixed on the housing of the fresh air actuator assembly. The upper water-blocking plate and the lower water-blocking plate are used to fix the filter screen.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model integrates multiple functions such as cooling, heating, fresh air, and same-side air intake and exhaust into one system. The entire system is designed as an independent, miniaturized integrated air conditioning system, which not only has multiple functions, but also improves the air quality inside the vehicle and increases the ventilation efficiency inside the vehicle. 2. This utility model can utilize fixing devices at different positions to achieve various fixing methods, making it highly practical; 3.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, a multifunctional independent micro air conditioning system includes an air conditioning housing 1, which is a cavity housing assembly that includes a front side panel, a rear side panel, a top panel, a bottom panel, and two side panels 11 on the left and right.

[0018] A cold core assembly 13 and a warm core assembly 12 are provided inside the air conditioner casing 1. The cold core assembly 13 is connected to the cold core air inlet and liquid outlet pipeline assembly 6, and the warm core assembly 12 is connected to the warm core water inlet and outlet pipeline assembly 5. In order to facilitate the connection of refrigerant, water, etc., the interfaces of the cold core air inlet and liquid outlet pipeline assembly 6 and the warm core water inlet and outlet pipeline assembly 5 are all located on the same side, that is, on one of the side plates 11, thereby improving the pipeline connection efficiency.

[0019] Two sets of through holes are added to the outer facade of the air conditioner housing 1. The structure of the through holes is not unique; they can be rectangular, circular, or other shapes. The upper through hole assembly serves as the air outlet 2, and the lower through hole assembly serves as the air inlet 3. The air outlet 2 and the air inlet 3 are located on the same side of the air conditioner housing 1, such as on the front panel, thus achieving the function of air inlet and outlet on the same side.

[0020] To enable various installation methods for the air conditioner, multiple mounting brackets 4 can be added around the air conditioner casing 1. The mounting brackets 4 can be connected to the air conditioner casing 1 by welding, riveting, bolting, or other methods. The mounting brackets 4 are provided with mounting holes, which can be used to achieve hanging, seated, side-mounted, and other installations of the entire air conditioner, making it highly versatile.

[0021] like Figure 2 As shown, a cold core assembly 13, a warm core assembly 12, and a fan assembly 14 are installed inside the air conditioner casing 1. The fan assembly 14 is fixed between the cold core assembly 13 and the warm core assembly 12 by a fan mounting bracket 15. On the one hand, the fan mounting bracket 15 can achieve better installation and fixation of the fan assembly 14; on the other hand, it can isolate the cold air space from the warm air space, preventing cold air and warm air from flowing together and affecting the cooling and heating effects.

[0022] Meanwhile, to better ensure airflow through the cold core assembly 13 during cooling, a guide vane 16 is added to the air inlet of the fan assembly 14, such as... Figure 5 , Figure 6 As shown, on the one hand, it can guide the airflow, allowing it to be drawn into the air conditioner casing from the fan inlet and pass entirely through the cold core assembly 13, thus improving cooling performance. On the other hand, it can further isolate the cold and warm spaces between the cold core assembly 13 and the warm core assembly 12, preventing crossflow.

[0023] Better still, a water box assembly 24 is provided at the lower part of the cold core assembly 13 and the warm core assembly 12. The water box assembly 24 is fixed on the air conditioner housing 1 and is connected to the water pipe 25.

[0024] To further improve the air exchange efficiency inside the vehicle, a fresh air inlet 8 is added to the side panel 11 on the other side of the air conditioner casing 1. The fan assembly 14 inside the air conditioner draws outside air into the air conditioner, cools it through the cooling core assembly 13, and then blows it into the vehicle, achieving rapid fresh air exchange. A fresh air actuator assembly 10 is installed at the rear end of the air duct of the fresh air inlet 8, such as... Figure 4 As shown, the fresh air actuator assembly 10 includes a fresh air actuator 17, which serves as the power source for the assembly. The output shaft of the fresh air actuator is connected to the left fixed shaft 18 and the right fixed shaft 22 via a coupling. A fresh air baffle 20 is bolted between the left fixed shaft 18 and the right fixed shaft 22. During assembly, the left fixed shaft 18 is mounted on the left side plate via bearings, and the right fixed shaft 22 is mounted on the right side plate via bearings. When the fresh air actuator 17 is working, the fresh air baffle 20 can rotate in a circular motion following the actuator 17, facilitating the opening and closing of the fresh air function. When fresh air exchange is not required, the fresh air actuator 17 is in its initial state, with the fresh air baffle 20 blocking the fresh air inlet 8 to prevent air leakage. When fresh air needs to be turned on, the fresh air actuator 17 drives the fresh air baffle 20 to rotate, opening the fresh air inlet 8 for ventilation.

[0025] Even better, the right fixed shaft 22 is also connected to a rotating handle 23, which allows the fresh air baffle 20 to be opened manually.

[0026] Meanwhile, an upper water-blocking plate 21 and a lower water-blocking plate 19 are fixed on the housing of the fresh air actuator assembly to fix the filter screen, so that the outside air can play a filtering function when it enters the air conditioner.

[0027] The working principle of this utility model is as follows: For the fresh air cooling (heating) function, the fresh air damper 20 can be opened and closed by the fresh air actuator, thereby using the fan assembly 14 to draw outside air from the fresh air inlet 8 into the air conditioner and pass through the cold (heating) core to improve the cooling (heating) effect. Then, the cold air is blown out to the air outlet by the fan assembly 14 to realize the cabin cooling function.

[0028] For heating, the cold core stops working, and the warm core begins heating. The fan blows the hot air directly to air outlet 2, thus achieving the heating function of the cockpit.

[0029] For cooling, the cold core starts working while the warm core stops heating. The fan blows the cold air directly to outlet 2, achieving the cooling function of the cockpit.

[0030] The beneficial effects of this utility model are as follows: 1. This small air conditioner can work independently. Compared with large bus air conditioners, it is small in size and light in weight, and can achieve cooling, heating and fresh air exchange functions in an independent chamber.

[0031] 2. These small air conditioners are all modular in structure, with few parts, making them easy to process and assemble. They are also easy to disassemble and reassemble.

[0032] 3. The air conditioner is designed with a cold chamber, a warm chamber, and a fresh air chamber. Each chamber can work independently without affecting the others.

[0033] 4. Eight fresh air inlets have been equipped with filter screens, and the fresh air inlets are designed with independent and detachable mechanisms for easy filter screen replacement.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
