Description

Technical Field

[0001] This utility model relates to an air conditioning device, and more particularly to a small air conditioning device that is small in size and suitable for small areas. Background Technology

[0002] Air conditioning plays an indispensable role in modern life. Whether in the sweltering summer or humid environments, it effectively regulates indoor temperature and humidity, providing a comfortable living and working environment. Whether in homes, offices, shopping malls, or cars, air conditioning significantly improves people's quality of life, especially in high-temperature regions where it is crucial for maintaining physical and mental health. Furthermore, many industrial and medical environments rely on air conditioning systems to ensure equipment operation or maintain specific temperature conditions, demonstrating that air conditioning has become an indispensable electrical appliance in modern society.

[0003] like Figure 1 As shown, a typical air conditioning unit 1 mainly consists of a compressor 11, a condenser 12, an expansion valve 13 (or a throttling device), an evaporator 14, and refrigerant (not shown in the figure). Its operating principle involves absorbing and releasing heat through the phase change process of the refrigerant. First, the compressor 11 compresses the low-pressure gaseous refrigerant into a high-pressure, high-temperature gas, which is then sent to the condenser 12 for heat dissipation, causing the refrigerant to transform into a high-pressure liquid. Next, the liquid refrigerant passes through the expansion valve 13 to reduce its pressure, enters the evaporator 14, and rapidly evaporates, absorbing heat from the room and thus lowering the air temperature. Finally, the gaseous refrigerant returns to the compressor 11 for recirculation, continuously circulating to maintain a cool indoor environment.

[0004] As mentioned above, air conditioning technology is already widespread and mature. However, with the changing lifestyles in recent years, the number of single-person or small family households is increasing, leading to a trend towards smaller residential buildings. Furthermore, with the rise of outdoor camping, more and more people are converting their cars into campervans. However, whether it's a small residential apartment or a campervan, the area is mostly less than 10 pings (approximately 3.3 square meters), especially for campervans, which are mostly less than 3 pings (approximately 1.3 square meters).

[0005] As mentioned above, for small spaces, especially for air conditioning in campervans, the commonly known sizes of air conditioning units are simply unsuitable. In other words, traditional air conditioning units are too large for the limited space, making installation impossible. Therefore, providing a compact air conditioning system suitable for small spaces is an important issue. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a small air conditioning device that can be used in small spaces.

[0007] To achieve the above objectives, this utility model provides a cooling device comprising a compressor, a condenser, an expansion valve, and an evaporator. The compressor outputs high-pressure gaseous refrigerant. The condenser includes a heat dissipation refrigerant pipe, through which the high-pressure gaseous refrigerant output from the compressor is dissipated, becoming high-pressure liquid refrigerant. The expansion valve is connected to the heat dissipation refrigerant pipe of the condenser and depressurizes the high-pressure liquid refrigerant into low-pressure refrigerant. The evaporator at least includes a refrigeration refrigerant pipe, through which the low-pressure refrigerant output from the expansion valve is input. The volume of refrigerant contained in the refrigeration refrigerant pipe is 300 cm³. 3 Up to 1000cm 3 .

[0008] In one embodiment, the air conditioning device of this invention further includes a high-pressure refrigerant pipe, one end of which is connected to the compressor and the other end of which is connected to the heat dissipation refrigerant pipe, so that high-pressure gaseous refrigerant is input into the heat dissipation refrigerant pipe.

[0009] In one embodiment, the air conditioning device of the present invention further includes a first throttling pipe, one end of which is connected to the heat dissipation refrigerant pipe of the condenser, and the other end of which is connected to an expansion valve, so as to allow the high-pressure liquid refrigerant to be input into the expansion valve.

[0010] In one embodiment, the volume of the heat dissipation refrigerant pipe is 1.2 to 1.5 times the volume of the cooling refrigerant pipe.

[0011] In one embodiment, the diameter of the cooling refrigerant pipe is 1 cm to 2.5 cm, while the diameter of the heat dissipation refrigerant pipe is 0.5 cm to 1.5 cm.

[0012] Furthermore, to achieve the above objectives, this utility model provides a cooling device, which includes a compressor, a condenser, an expansion valve, and an evaporator; the compressor outputs high-pressure gaseous refrigerant; the condenser includes a heat dissipation refrigerant pipe, through which the high-pressure gaseous refrigerant output from the compressor is input to dissipate heat, thus becoming high-pressure liquid refrigerant; the expansion valve is connected to the heat dissipation refrigerant pipe of the condenser and reduces the pressure of the high-pressure liquid refrigerant to low-pressure refrigerant; and the evaporator includes a first refrigeration refrigerant pipe and a second refrigeration refrigerant pipe, through which the low-pressure refrigerant output from the expansion valve is respectively input to the first refrigeration refrigerant pipe and the second refrigeration refrigerant pipe.

[0013] In one embodiment, the evaporator further includes a refrigerant inlet pipe and a refrigerant outlet pipe. One end of the first refrigerant pipe and one end of the second refrigerant pipe are respectively connected to the refrigerant inlet pipe; while the other ends of the first refrigerant pipe and the second refrigerant pipe are respectively connected to the refrigerant outlet pipe.

[0014] In one embodiment, the air conditioning device of this invention further includes a high-pressure refrigerant pipe, one end of which is connected to the compressor and the other end of which is connected to the heat dissipation refrigerant pipe, so that high-pressure gaseous refrigerant is input into the heat dissipation refrigerant pipe.

[0015] In one embodiment, the air conditioning device of this utility model further includes a first throttling pipe, one end of which is connected to the heat dissipation refrigerant pipe of the condenser, and the other end of which is connected to an expansion valve, so as to allow high-pressure liquid refrigerant to be input into the expansion valve.

[0016] In one embodiment, the volume of the refrigerant contained in the first or second refrigerant pipe is 300 cm³. 3 Up to 500cm 3 .

[0017] In one embodiment, the volume of the heat dissipation refrigerant pipe is 1.2 to 1.5 times the sum of the volumes of the first and second refrigerant pipes.

[0018] In one embodiment, the diameter of the first or second cooling refrigerant pipe is 1 cm to 2.5 cm; while the diameter of the heat dissipation refrigerant pipe is 0.5 cm to 1.5 cm.

[0019] In summary, since the refrigerant volume contained in the first or second refrigerant pipe of the air conditioning equipment of this utility model is 300 cm³, 3 Up to 500cm 3 Furthermore, the diameter of the first or second refrigerant pipe is 1cm to 2.5cm; therefore, the length of the first or second refrigerant pipe in this invention is limited to a certain length, and considering its circuitous arrangement, the size of the evaporator in this invention can be very small. In addition, because the volume of the heat dissipation refrigerant pipe in this invention is 1.2 to 1.5 times the combined volume of the first and second refrigerant pipes, the condenser in this invention is also relatively smaller. Since both the condenser and evaporator in this invention are very small, the overall air conditioning system can be very small and is suitable for installation and use in small areas.

[0020] Furthermore, since the evaporator of the air conditioning equipment of this invention includes a first refrigerant pipe and a second refrigerant pipe, low-pressure refrigerant can be quickly introduced and discharged from the two refrigerant pipes, thereby quickly exchanging heat and achieving a rapid cooling effect.

[0024] Figure 4 This is another schematic diagram illustrating the components of the air conditioning device of this utility model. Detailed Implementation

[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 2 As shown, the air conditioning device 2 of this utility model includes a compressor 21, a condenser 22, an expansion valve 23, and an evaporator 24.

[0027] The compressor 21 outputs high-pressure gaseous refrigerant via high-pressure refrigerant pipe 211. The condenser 22 includes a heat dissipation refrigerant pipe 221 and multiple heat dissipation fins 222. The high-pressure gaseous refrigerant output from the compressor 21 is input into the heat dissipation refrigerant pipe 221 and dissipated through these heat dissipation fins 222, turning it into high-pressure liquid refrigerant. The expansion valve 23 is connected to the heat dissipation refrigerant pipe 221 of the condenser 22 via a first throttling pipe 231, and reduces the pressure of the high-pressure liquid refrigerant to low-pressure refrigerant.

[0028] Please refer to this again. Figure 2 and Figure 3 As shown, the evaporator 24 includes a first refrigerant pipe 241, a second refrigerant pipe 242, and multiple heat exchange fins 243. The low-pressure refrigerant output from the expansion valve 23 flows through the second throttling pipe 232 and is then introduced into the first refrigerant pipe 241 and the second refrigerant pipe 242 via the refrigerant inlet pipe 244. It is worth noting that, in another embodiment, the first refrigerant pipe 241 and the second refrigerant pipe 242 can also be interconnected to form a single refrigerant pipe. In this case, the refrigerant inlet pipe 244 is directly connected to one end of the refrigerant pipe (not shown in the figure).

[0029] Please refer to this again. Figure 2 and Figure 3 As shown, the low-pressure refrigerant flows through the second expansion tube 232 and is then introduced into the first refrigeration refrigerant pipe 241 and the second refrigeration refrigerant pipe 242 via the refrigerant inlet pipe 244. After heat exchange, the refrigerant is then discharged through the refrigerant outlet pipe 245 and enters the compressor 21 via the low-pressure refrigerant pipe 212. It is worth mentioning that, in another embodiment, the first refrigeration refrigerant pipe 241 and the second refrigeration refrigerant pipe 242 can also be interconnected to form a single refrigeration refrigerant pipe. In this case, the refrigerant outlet pipe 245 is directly connected to the other end of the refrigeration refrigerant pipe (not shown in the figure).

[0030] As stated above, although the evaporator 24 of this utility model includes a first refrigeration refrigerant pipe 241 and a second refrigeration refrigerant pipe 242, it can also be constructed using a single refrigeration refrigerant pipe in another embodiment. However, regardless of whether it consists of two refrigeration refrigerant pipes or a single refrigeration refrigerant pipe, the refrigerant volume contained in the single refrigeration refrigerant pipe can be limited to 300 cm³. 3 Up to 1000cm 3 However, when using two refrigerant pipes, the volume of refrigerant contained in either pipe can be limited to 300 cm³. 3 Up to 500cm 3 .

[0031] Furthermore, to accelerate heat dissipation, the volume of the heat dissipation refrigerant pipe 221 in the condenser 22 of this invention can be 1.2 to 1.5 times the total volume of the refrigeration refrigerant pipes 241 and 242. Moreover, the diameter of the refrigeration refrigerant pipes 241 and 242 can be 1 cm to 2.5 cm; while the diameter of the heat dissipation refrigerant pipe 221 is 0.5 cm to 1.5 cm.

[0032] It is worth mentioning that, such as Figure 4 As shown, in practical applications, the low-pressure refrigerant pipe 212 and the second throttling pipe 232 of this utility model can be extended and lengthened, so that the air conditioning equipment 2 of this utility model has an indoor unit and an outdoor unit application mode. In other words, the condenser 22 and the compressor 21 can be placed outdoors, while the evaporator 24 is placed indoors.

[0033] In summary, since the refrigerant volume contained in the first refrigerant pipe 241 or the second refrigerant pipe 242 of the air conditioning equipment of this utility model is 300 cm³, 3 Up to 500cm 3 Furthermore, the diameters of the first and second refrigerant pipes 241 and 242 are 1 cm to 2.5 cm. Therefore, the length of the first refrigerant pipe 241 or the second refrigerant pipe 242 is limited to a certain length, and considering its meandering arrangement, the size of the evaporator can be very small. Additionally, because the volume of the heat dissipation refrigerant pipe 221 is 1.2 to 1.5 times the combined volume of the first and second refrigerant pipes 241 and 242, the condenser is also relatively smaller. Since both the condenser 22 and the evaporator 24 are small, the overall air conditioning system can be very small and suitable for installation and use in small spaces.

[0034] Furthermore, since the evaporator 24 of the air conditioning device 2 of this utility model includes a first refrigerant pipe 241 and a second refrigerant pipe 242, the low-pressure refrigerant can be quickly introduced and discharged from the two refrigerant pipes, thereby quickly exchanging heat and achieving a rapid cooling effect.
