For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] Reference is made below to Figure 1 - Figure 2 describe the integrated air conditioner 100 according to an embodiment of the present utility model.

[0028] The integrated air conditioner 100 according to an embodiment of the present utility model is an air conditioning system that does not require separate installation of an indoor unit and an outdoor unit. The integrated air conditioner 100 integrates a compressor 33, a condenser 20, an evaporator 34, a blower, and a control system - all in a single housing, which is convenient for installation and use. The integrated air conditioner 100 is divided into a fixed type and a movable type. The fixed integrated air conditioner can be installed on a window, a wall, or a ceiling, and the fixed integrated air conditioner needs to be connected to an exhaust pipe to discharge hot air outdoors; the bottom of the movable integrated air conditioner 100 is provided with rollers and can be moved in multiple rooms, but it also needs to be connected to an exhaust pipe to discharge hot air outdoors.

[0029] The integrated air conditioner 100 of the present application takes the integrated air conditioner 100 installed on the ceiling as an example.

[0030] The integrated air conditioner 100 includes a condenser 20 and a water impeller 31. The condenser 20 includes a plurality of rows of fin plates 21 arranged in parallel. The plurality of rows of fin plates 21 arranged in parallel can make full use of the internal space of the integrated air conditioner 100. A heat exchange tube is disposed through each fin plate 21, and the plurality of rows of fin plates 21 are arranged along a first direction (for example, referring to the Figure 1 e1 direction in the drawing), and the first direction can be a horizontal direction, and the plurality of rows of fin plates 21 are arranged in sequence along the horizontal direction.

[0031] A part of the fin plates 21 arranged in sequence in the multi-row fin plate 21 is the first fin plate group 22, and another part of the fin plates 21 arranged in sequence is the second fin plate group 23. The first fin plate group 22 and the second fin plate group 23 are spaced apart along the first direction. The water spraying wheel 31 is located between the first fin plate group 22 and the second fin plate group 23. When the water spraying wheel 31 rotates, it breaks the condensed water into small water droplets or water mist and throws them onto the condenser 20, increasing the contact area between the condensed water and the condenser 20, improving the utilization rate of the cooling capacity of the condensed water, thereby enhancing the heat exchange efficiency and bringing a better experience to users. On the other hand, since the water spraying wheel 31 is located between the first fin plate group 22 and the second fin plate group 23, when the water spraying wheel 31 rotates, the water splashed out can be prevented from splashing outside the body, effectively increasing the stability of the system.

[0032] When the refrigerant comes out of the compressor 33, it is in a high-temperature and high-pressure gas state, and then flows into the heat exchange tubes of the condenser 20. When flowing in the heat exchange tubes of the condenser 20, the condenser 20 can conduct heat exchange between the refrigerant and the outside air, so that the temperature of the refrigerant becomes lower and lower during the process of flowing in the heat exchange tubes of the condenser 20. Among them, the temperature of the refrigerant in the first fin plate group 22 is higher than that in the second fin plate group 23, that is, the refrigerant first flows through the first fin plate group 22 and then through the second fin plate group 23. Since the water spraying wheel 31 is located between the first fin plate group 22 and the second fin plate group 23, the position of the water spraying wheel 31 can be reasonably arranged, so that when the water spraying wheel 31 breaks up the condensed water, the contact area between the condensed water and the first fin plate group 22 in the high-temperature section can be increased. The first fin plate group 22 can not only quickly consume the condensed water, but also improve the heat exchange efficiency of the condenser 20.

[0033] The refrigerant used in this application can be azeotropic refrigerant, and the main components are R32, R134a and CO 2 , R32 has a higher volumetric refrigerating capacity, R134a is used to adjust the system pressure and exhaust temperature and is flame retardant, and a small amount of CO 2 is used to adjust the temperature glide. Refer to the attached Figure 2 , Figure 2 The abscissa of is the dry bulb and wet bulb temperatures, the high temperature is the wet bulb temperature, the low temperature is the dry bulb temperature, the ordinate is the energy efficiency ratio, and the red bar chart is the energy efficiency ratio of pure CO 2 refrigerant, and the blue bar chart is the energy efficiency ratio of the azeotropic refrigerant. Refer to Figure 2 It can be seen that compared with the pure CO 2 refrigerant, the azeotropic refrigerant has a higher energy efficiency ratio at the same temperature.

[0034] The refrigerant used in the present application is a non-azeotropic mixed refrigerant. Only one water wheel 31 is used in the integrated air conditioner 100. Due to the characteristics of the non-azeotropic mixed refrigerant, it can not only meet the heat exchange efficiency of the condenser 20, but also save the cost of the integrated air conditioner 100.

[0035] According to the integrated air conditioner 100 of the embodiment of the utility model, the condenser 20 includes a first fin plate group 22 and a second fin plate group 23, the refrigerant temperature in the first fin plate group 22 is greater than the refrigerant temperature in the second fin plate group 23, the water wheel 31 is located between the first fin plate group 22 and the second fin plate group 23, and the position of the water wheel 31 can be reasonably arranged so that when the water wheel 31 disperses the condensed water, the condensed water can be thrown onto the first fin plate group 22 and the second fin plate group 23, so that the contact surface between the condensed water and the condenser 20 is increased, and the cold capacity utilization rate of the condensed water is improved. At the same time, the contact area between the condensed water and the first fin plate group 22 in the high temperature section can be increased. The first fin plate group 22 can not only quickly consume the condensed water, but also improve the heat exchange efficiency of the condenser 20.

[0036] According to some embodiments of the present invention, referring to Figure 1 The integrated air conditioner 100 also includes an exhaust fan 32, which is arranged on the side of the first fin plate group 22 away from the water wheel 31, and the air inlet end of the exhaust fan 32 faces the first fin plate group 22. The exhaust fan 32 is used to discharge the heat dissipated by the condenser 20 outdoors.

[0037] The first fin plate group 22 is located between the water wheel 31 and the exhaust fan 32. When the water wheel 31 rotates, the condensed water is broken up into fine water droplets or water mist. When the exhaust fan 32 is running, the fine water droplets or water mist stirred up by the water wheel 31 will be attracted by the exhaust fan 32. In the process of being attracted by the exhaust fan 32, the fine water droplets or water mist will pass through the first fin plate group 22 and be attracted to the exhaust fan 32, so that the fine water droplets or water mist can better penetrate the first fin plate group 22; wherein, the refrigerant temperature in the first fin plate group 22 is greater than the refrigerant temperature in the second fin plate group 23, the first fin plate group 22 can quickly consume the content of condensed water, and can also improve the heat exchange efficiency of the condenser 20.

[0038] According to some embodiments of the present invention, referring to Figure 1 The integrated air conditioner 100 also includes an evaporator 34 and a water receiving pan. The evaporator 34 and the condenser 20 are spaced apart along a first direction. The water receiving pan is arranged on one side of the evaporator 34 and the condenser 20 in a second direction for receiving condensed water of the evaporator 34, wherein the first direction is perpendicular to the second direction.

[0039] The second direction may be the up-and-down direction. The water receiving tray is arranged below the evaporator 34 and the condenser 20. During the heat exchange process of the evaporator 34, condensed water can be generated, and the condensed water can flow to the water receiving tray. Since the water receiving tray is located below the condenser 20, the condensed water in the water receiving tray can flow to the condenser 20, facilitating the water wheel 31 located between the first fin plate group 22 and the second fin plate group 23 to throw the condensed water in the water receiving tray onto the first fin plate group 22 and the second fin plate group 23.

[0040] According to some embodiments of the present invention, referring to Figure 1 , within the spaced-apart space 24 between the first fin plate group 22 and the second fin plate group 23, the water wheel 31 is located on one side of the spaced-apart space 24 in the third direction (for example, referring to the e3 direction in Figure 1 ), wherein the first direction is perpendicular to the third direction. By arranging the water wheel 31 on one side of the spaced-apart space 24 in the third direction, the flow of air or water can be more effectively utilized to promote heat exchange, reducing resistance and noise: placing the water wheel 31 on a specific side rather than in the exact middle can also reduce the resistance of air flow and lower the noise level.

[0041] Figure 1 According to some embodiments of the present invention, referring to Figure 1 , the number of fin plates 21 is a, satisfying: a≥4. The fin plates 21 can be arranged in four rows, or the fin plates 21 can be arranged in more than four rows, which can improve the heat exchange efficiency of the condenser 20. For example, the fin plates 21 can be arranged in four rows, five rows, six rows, or seven rows, etc.

[0042] When the fin plates 21 are arranged in four rows, the first fin plate group 22 may include two rows of fin plates 21 arranged in sequence, and the second fin plate group 23 may include the remaining two rows of fin plates 21 arranged in sequence. When the fin plates 21 are arranged in five rows, the first fin plate group 22 may include two rows of fin plates 21 arranged in sequence, and the second fin plate group 23 may include the remaining three rows of fin plates 21 arranged in sequence; or, the first fin plate group 22 may include three rows of fin plates 21 arranged in sequence, and the second fin plate group 23 may include the remaining two rows of fin plates 21 arranged in sequence.

[0043] According to some embodiments of the present invention, referring to Figure 1 , the number of fin plates 21 in the first fin plate group 22 is equal to the number of fin plates 21 in the second fin plate group 23, and the water wheel 31 is located at the middle position of the multiple rows of parallel fin plates 21, so that the amount of condensed water consumed by the first fin plate group 22 and the second fin plate group 23 is the same, and the heat exchange efficiency of the refrigerant in the first fin plate group 22 and the second fin plate group 23 is the same.

[0044] Alternatively, the difference in the number of fin plates 21 between the first fin plate group 22 and the second fin plate group 23 is 1. When the number of rows of fin plates 21 arranged in parallel is odd, the number of fin plates 21 in the first fin plate group 22 can be one more than that in the second fin plate group 23, or the number of fin plates 21 in the second fin plate group 23 can be one more than that in the first fin plate group 22, so that the number of fin plates 21 in the first fin plate group 22 and the second fin plate group 23 is closer, avoiding a large difference in the amount of condensed water consumed by the first fin plate group 22 and the second fin plate group 23, and further avoiding a large difference in the heat exchange efficiency between the first fin plate group 22 and the second fin plate group 23.

[0045] According to some embodiments of the present invention, referring to Figure 1 , the integrated air conditioner 100 further includes a housing 10. The housing 10 includes a first housing 11 and a second housing 12 connected to each other. The condenser 20 is located in the first housing 11, and the evaporator 34 is located in the second housing 12. The integrated air conditioner 100 is designed with module partitioning, and the condenser 20 and the evaporator 34 are respectively located in different housings 10. In the first direction, there is an avoidance space 13 between the first housing 11 and the second housing 12. The avoidance space 13 is used to avoid the mounting bracket for mounting the integrated air conditioner 100, so that the integrated air conditioner 100 can avoid the housing 10 during installation, realizing damage-free installation.

[0046] In a specific example, a compressor 33 is further installed in the first housing 11. The compressor 33 is located on one side of the condenser 20 and is connected to the condenser 20. The compressor 33 is used to compress the refrigerant flowing out of the evaporator 34 and transfer the compressed refrigerant into the condenser 20.

[0047] An electric control box 36 and a blower fan 35 are further installed in the second housing 12. The evaporator 34 is bent to form a receiving cavity 341. The blower fan 35 is located in the receiving cavity 341. The blower fan 35 is used to blow the cold or heat of the evaporator 34 into the room. The electric control box 36 is installed on one side of the evaporator 34 for controlling the air conditioning system.

[0048] According to some embodiments of the present invention, referring to Figure 1 , one side of the first housing 11 and the second housing 12 communicates in the second direction to form a communication port, and the other side of the first housing 11 and the second housing 12 in the second direction is the avoidance space 13. The water receiving tray passes through the communication port, so that the condensed water generated by the evaporator 34 can flow to the lower part of the condenser 20 through the water receiving tray, which can not only realize the consumption of condensed water, but also improve the heat exchange efficiency of the condenser 20.

[0049] According to some embodiments of the present invention, referring toFigure 1 The housing 10 has a mounting portion on the side facing away from the water receiving tray. The housing 10 is mounted to the interior through the mounting portion. The mounting portion can be located above the housing 10, and the water receiving tray can be located below the housing 10, facilitating the condensed water generated by the evaporator 34 to flow into the water receiving tray.

[0050] According to some embodiments of the present utility model, with reference to Figure 1 Both the first housing 11 and the second housing 12 are square housings. The square housing can make more effective use of space and reduce waste in installation and layout; and the square housing has higher structural stability and can withstand greater external forces and pressures.
