Description

Technical Field

[0001] This application relates to the field of air conditioning equipment manufacturing, and more particularly to a modular air conditioner. Background Technology

[0002] An integrated air conditioner, also known as an air conditioner, is a device that uses artificial means to adjust and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, people need cool air in the kitchen. Since the kitchen was not designed with a space reserved for the installation of a complete air conditioner, a single integrated air conditioner is used in the kitchen.

[0004] In the existing technology, due to the limited space in the kitchen, in order to meet the needs of both outputting cold air and producing hot water in daily use, a water tank is installed inside the integrated air conditioner. The addition of the water tank will increase the size of the integrated air conditioner, thus taking up more kitchen space and failing to meet the need for miniaturization. Utility Model Content

[0005] This application discloses an integrated air conditioner that can reduce the size of the integrated air conditioner in the width and length directions while meeting the requirements of outputting cold air and hot water, thus satisfying the miniaturization requirements of integrated air conditioners.

[0006] To achieve the above objectives, some embodiments of this application provide an integrated air conditioner, comprising:

[0007] A housing having a first receiving cavity and a second receiving cavity formed therein;

[0008] A refrigerant heat exchange system, comprising:

[0009] The first heat exchanger is disposed in the first receiving cavity and is used for heat exchange between the refrigerant and the air.

[0010] The compressor is located in the second receiving cavity and is connected to the first heat exchanger. The compressor is used to provide power for the flow of refrigerant.

[0011] A water tank, which is disposed within the second receiving cavity, is used to store hot water;

[0012] The second heat exchanger is disposed in the second receiving cavity and is used for heat exchange between the refrigerant and water. The second heat exchanger includes heat exchange pipelines.

[0013] The heat exchange pipeline includes:

[0014] Refrigerant piping, which is connected to the compressor, is used to circulate refrigerant;

[0015] A water pipe is installed around the refrigerant pipe, with one end of the water pipe connected to an external water source and the other end connected to the water tank.

[0016] The heat exchange piping of the second heat exchanger is arranged around the outer periphery of the compressor.

[0017] The integrated air conditioner of some embodiments of this application has a first receiving cavity and a second receiving cavity formed in its casing. A first heat exchanger is provided in the first receiving cavity for heat exchange between refrigerant and air, so that the integrated air conditioner can blow out cold air. A compressor is provided in the second receiving cavity and is connected to the first heat exchanger to provide power for the flow of refrigerant. A water tank is also provided in the second receiving cavity for storing hot water. A second heat exchanger is also provided in the second receiving cavity for heat exchange between refrigerant and water. The second heat exchanger includes heat exchange pipelines, which include refrigerant pipelines and water pipelines. The refrigerant pipelines are connected to the compressor and are used to circulate refrigerant. One end of the water pipeline is used to connect to an external water source, and the other end is connected to the water tank. The heat exchange pipelines are arranged around the outer periphery of the compressor.

[0018] In this way, the water pipes of the second heat exchanger are connected to the water tank, so that the second heat exchanger can supply water heated by the heat released by the refrigerant to the water tank for user use while exchanging heat. At the same time, the heat exchange pipes of the second heat exchanger are arranged around the outer periphery of the compressor. This compact layout design saves space, so that there is no need to design a separate space for the heat exchange pipes of the second heat exchanger in the second housing cavity. This can reduce the size of the integrated air conditioner in the length and width directions, so that the integrated air conditioner can meet the requirements of miniaturization. Furthermore, the heat exchange pipes are arranged around the outer periphery of the compressor, which also makes it easier for the heat exchange pipes to use the heat generated by the compressor to heat the water in the water pipes, thereby improving the thermal efficiency of the refrigerant heat exchange system.

[0019] In some embodiments of this application, the heat exchange pipeline of the second heat exchanger is spirally coiled around the outer periphery of the compressor.

[0020] In this way, the spirally coiled heat exchange pipes can significantly increase the contact area between the refrigerant and the water, thereby improving the heat exchange efficiency of the heat exchange pipes.

[0021] In some embodiments of this application, the heat exchange pipeline and the compressor have a first preset gap.

[0022] Thus, the existence of the first preset gap can reduce the direct contact between the heat exchange pipeline and the compressor, thereby avoiding heat loss caused by heat conduction between the two. In addition, the compressor will vibrate when it is operating, and the existence of the first preset gap can prevent the heat exchange pipeline and the compressor from resonating, thus preventing damage to the heat exchange pipeline.

[0023] In some embodiments of this application, the first preset gap is 20-25 mm.

[0024] Thus, with a preset gap of 20-25mm, the heat exchange coil can fit more tightly against the compressor's outer perimeter, saving space and reducing the size of the integrated air conditioner. Furthermore, it can reduce the flow resistance of the refrigerant in the heat exchange piping to some extent, lowering the energy consumption of the integrated air conditioner.

[0025] In some embodiments of this application, the heat exchange pipeline is coiled to form multiple heat exchange coils, the multiple heat exchange coils are arranged in a vertical direction and adjacent heat exchange coils are in close contact with each other.

[0026] Thus, on the one hand, the close fit between adjacent heat exchange coils helps to form a continuous heat transfer path, which can reduce heat loss during the transfer process and improve the efficiency and speed of heat transfer; on the other hand, the vertically arranged heat exchange coils can make more effective use of space and improve space utilization.

[0027] In some embodiments of this application, the compressor and the water tank are arranged horizontally, and the heat exchange pipeline and the water tank have a second preset gap.

[0028] Thus, the existence of the second preset gap can reduce the direct contact between the heat exchange pipe and the water tank, which helps to maintain the stable temperature of the refrigerant in the heat exchange pipe, improve the heat exchange efficiency, and avoid potential safety hazards caused by overheating, vibration or leakage, thus helping to improve the safety and reliability of the integrated air conditioner.

[0029] In some embodiments of this application, the second preset gap is 20-25 mm.

[0030] Thus, by setting the second preset gap to 20-25mm, within this range, it can be ensured that the water tank and the heat exchange pipes of the second heat exchanger will not come into direct contact, and the distance between the water tank and the heat exchange pipes can be minimized as much as possible, thereby reducing the size of the integrated air conditioner.

[0031] In some embodiments of this application, the housing includes:

[0032] The lower housing, the second receiving cavity being located within the lower housing;

[0033] The upper housing is located above the lower housing, and the first receiving cavity is located inside the upper housing. The upper housing has an air outlet and an air inlet, and both the air outlet and the air inlet are connected to the first receiving cavity.

[0034] In this way, by setting different housing cavities in the lower and upper housings respectively, space can be utilized more effectively, making the structure of the entire housing more compact. Furthermore, the separate design of the upper and lower housings makes the installation and maintenance process simpler. With both the air outlet and air inlet located in the upper housing and the lower housing having a complete exterior, the overall aesthetic appearance of the integrated housing can be improved.

[0035] In some embodiments of this application, the air outlet and the air inlet are located on the same side of the upper housing.

[0036] In this way, when the air outlet and air inlet are located on the same side, the airflow path inside the casing can be simplified, allowing air to enter and leave the casing more directly, reducing unnecessary turns and eddies, thereby improving ventilation efficiency. Furthermore, having the air outlet and air inlet on the same side can reduce the size of the integrated air conditioner, which is beneficial for miniaturization.

[0037] In some embodiments of this application, the water tank is provided with an overflow port, and the integrated air conditioner further includes:

[0038] A water collection device is located inside the second receiving cavity and is disposed on the lower side of the water tank, and the overflow port is connected to the water collection device.

[0039] In this way, when the water level in the tank exceeds the preset height, the excess water can flow into the water collection device through the overflow port, thereby avoiding damage to the water tank due to overflow or other safety hazards. This helps ensure the normal operation of the integrated air conditioner and prevents potential risks such as short circuits and leakage caused by water tank overflow.

[0040] In some embodiments of this application, a water receiving tray is provided on the lower side of the first heat exchanger, the water receiving tray is connected to the water collecting device, and the water receiving tray is used to collect the condensate flowing out of the first heat exchanger.

[0041] Thus, the drip tray ensures that the condensate flowing from the first heat exchanger is effectively collected, preventing it from dripping directly onto other components or the ground, thus avoiding damage or safety hazards. By connecting the drip tray to the water collection device, the condensate can be smoothly discharged into the device for further treatment or reuse, helping to keep the integrated air conditioner clean and dry, and improving its stability and reliability.

[0042] In some embodiments of this application, the water receiving tray has a first end close to the first heat exchanger and a second end away from the first heat exchanger, with the first end being higher than the second end, so as to guide the condensate from the first heat exchanger into the water collecting device.

[0043] Thus, since the first end of the water receiving tray is higher than the second end, the condensate will naturally flow from the first end to the second end under the action of gravity, ensuring that the condensate can flow smoothly along the inclined surface of the water receiving tray and will not accumulate below the first heat exchanger. The condensate can flow into the water collection device more quickly, thereby avoiding the risk of overflow and leakage.

[0044] In some embodiments of this application, a drain outlet is also provided on the side of the housing, and the integrated air conditioner further includes:

[0045] A drainage pump, wherein the inlet of the drainage pump is connected to the water collection device, and the outlet of the drainage pump is connected to the drain outlet, and the drainage pump is used to discharge water from the water collection device.

[0046] In this way, the drain pump can actively extract water from the water collection device and quickly discharge it into the external environment through the drain outlet, ensuring that too much water does not accumulate in the water collection device, thereby avoiding the risk of performance degradation or failure of the refrigerant heat exchange system due to water accumulation.

[0047] In some embodiments of this application, the integrated air conditioner further includes:

[0048] A water level monitoring module is installed on the water collection device and is electrically connected to the drainage pump. The water level monitoring module is used to monitor the water level of the water collection device.

[0049] In this way, the water level monitoring module can monitor the water level changes in the water collection device in real time. After the water level monitoring module is electrically connected to the drainage pump, intelligent drainage control can be realized. When the water level is too high, the module will automatically start the drainage pump to drain the water, avoiding system problems caused by excessive water accumulation. At the same time, the automated drainage control can adjust the working status of the drainage pump according to actual needs, avoiding unnecessary energy consumption and improving the overall energy efficiency of the system.

[0050] In some embodiments of this application, a cold water inlet is further provided on the side of the housing, the cold water inlet being connected to the water pipe of the second heat exchanger, and the integrated air conditioner further includes:

[0051] A solenoid valve is disposed between the cold water inlet and the second heat exchanger to control the flow rate of cold water.

[0052] Thus, the solenoid valve's regulating function allows the system to adapt to different operating conditions and load changes. Under low load conditions, the chilled water flow rate can be reduced to lower energy consumption; under high load conditions, the chilled water flow rate can be increased to meet cooling demands. The solenoid valve precisely controls the chilled water flow rate entering the second heat exchanger, ensuring optimal energy efficiency under various operating conditions. By adjusting the chilled water flow rate, the system's cooling effect can be optimized, reducing unnecessary energy consumption.

[0053] In some embodiments of this application, the integrated air conditioner further includes:

[0054] A throttling device is provided between the refrigerant pipeline of the second heat exchanger and the first heat exchanger, and the throttling device is used to throttle the refrigerant.

[0055] In this way, by throttling the refrigerant, the throttling device can control the flow rate and pressure of the refrigerant in the system, thereby effectively regulating the pressure and temperature inside the refrigerant heat exchange system and maintaining the stable operation of the refrigerant heat exchange system.

[0056] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0057] This application provides an integrated air conditioner, including a casing and a refrigerant heat exchange system. The casing contains a first cavity and a second cavity. The refrigerant heat exchange system includes a first heat exchanger, a compressor, a water tank, and a second heat exchanger. The first heat exchanger is located in the first cavity and is used for heat exchange between the refrigerant and air. The compressor is located in the second cavity and is connected to the first heat exchanger, providing power for the flow of the refrigerant. The water tank is located in the second cavity and is used to store hot water. The second heat exchanger is located in the second cavity and is used for heat exchange between the refrigerant and water. The second heat exchanger includes heat exchange pipes, including refrigerant pipes and water pipes. The refrigerant pipes are connected to the compressor and are used to circulate the refrigerant. The water pipes are sleeved around the refrigerant pipes, with one end connected to an external water source and the other end connected to the water tank. The heat exchange pipes of the second heat exchanger are arranged around the outer periphery of the compressor. In this way, the heat exchange pipes of the second heat exchanger are arranged around the outer periphery of the compressor, so that there is no need to design a separate space for the heat exchange pipes inside the casing. This allows the integrated air conditioner to be smaller in both width and length, even with a water tank for storing hot water to meet the requirements of simultaneously outputting cold air and hot water. This meets the need for miniaturization of integrated air conditioners. Attached Figure Description

[0077] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0078] Please see Figures 1 to 3 In one embodiment of this application, the integrated air conditioner 100 includes a housing 1, and a first receiving cavity 1a and a second receiving cavity 1b are formed in the housing 1. The first receiving cavity 1a and the second receiving cavity 1b are used to house the functional components of the integrated air conditioner 100.

[0079] The integrated air conditioner 100 also includes a refrigerant heat exchange system 2, which includes a first heat exchanger 21 disposed in a first receiving cavity 1a. The first heat exchanger 21 is used for heat exchange between the refrigerant and the air.

[0080] The refrigerant heat exchange system 2 also includes a compressor 22, which is located in the second receiving cavity 1b. The compressor 22 is connected to the first heat exchanger 21. The compressor 22 is used to draw in low-temperature and low-pressure refrigerant and then compress it into high-temperature and high-pressure refrigerant through mechanical movement, so that the refrigerant can release more heat and provide power for the flow and circulation of the refrigerant.

[0081] The refrigerant heat exchange system 2 also includes a water tank 23, which is located in the second receiving cavity 1b and is used to store hot water.

[0082] The refrigerant heat exchange system 2 also includes a second heat exchanger 24, which is located within the second receiving cavity 1b. The second heat exchanger 24 is used for heat exchange between the refrigerant and water. The second heat exchanger 24 includes a heat exchange pipe 241, which includes a refrigerant pipe 2411 connected to the compressor 22 for refrigerant flow. The heat exchange pipe 241 also includes a water pipe 2412, which is fitted around the refrigerant pipe 2411. One end of the water pipe 2412 is connected to an external water source, and the other end is connected to a water tank 23. The heat exchange pipe 241 of the second heat exchanger 24 is arranged around the outer periphery of the compressor 22.

[0083] In this way, the first heat exchanger 21, compressor 22, water tank 23 and second heat exchanger 24 form a complete refrigerant heat exchange circuit. The high temperature and high pressure refrigerant output from the compressor 22 enters the second heat exchanger 24 through the refrigerant pipeline 2411. Cold water flows in the water pipeline 2412 of the second heat exchanger 24. Through the heat exchange between the cold water and the refrigerant, the refrigerant becomes a low temperature and low pressure state after passing through the second heat exchanger 24. At the same time, the cold water is made into hot water after the heat exchange of the refrigerant, and enters the water tank 23 through the water pipeline 2412 for storage for the user's daily use.

[0084] Because a water tank 23 is installed in the second receiving cavity 1b to store hot water, the integrated air conditioner 100 can provide hot water to users while still being able to output cold air. However, installing a water tank 23 in the second receiving cavity 1b will increase the size of the integrated air conditioner 100, causing it to occupy more kitchen space.

[0085] Therefore, in the integrated air conditioner 100 of this application embodiment, the heat exchange pipe 241 of the second heat exchanger 24 is arranged around the outer periphery of the compressor 22. This compact layout design saves space in the second receiving cavity 1b, so that there is no need to design a separate space for the heat exchange pipe 241 of the second heat exchanger 24 in the second receiving cavity 1b. This can reduce the size of the integrated air conditioner 100 in the length and width directions, so that the integrated air conditioner 100 can meet the requirements of miniaturization. Furthermore, the arrangement of the heat exchange pipe 241 around the outer periphery of the compressor 22 is also beneficial for the heat exchange pipe 241 to use the heat generated when the compressor 22 is operating to heat the water in the water pipe 2412 of the heat exchange pipe 241, which can improve the thermal efficiency of the refrigerant heat exchange system 2.

[0086] In some embodiments, such as Figure 3 As shown, the heat exchange pipe 241 of the second heat exchanger 24 is spirally coiled around the outer periphery of the compressor 22. That is to say, the heat exchange pipe 241 of the second heat exchanger 24 is coiled around the outer periphery of the compressor 22 in a spiral shape.

[0087] In this way, on the one hand, the spirally coiled heat exchange pipe 241 can significantly increase the contact area between the refrigerant and the water, thereby improving the heat exchange efficiency. This allows heat to be transferred more effectively from the refrigerant to the water, or from the water to the refrigerant, achieving efficient heat exchange. On the other hand, the spirally coiled heat exchange pipe 241 causes the fluid to frequently change direction as it flows within the pipe, creating localized turbulence. Turbulence can more effectively disrupt the fluid boundary layer, reduce thermal resistance, and thus improve the heat transfer coefficient.

[0088] Furthermore, such as Figure 4 As shown, there is a first preset gap M between the heat exchange pipe 241 of the second heat exchanger 24 and the compressor 22. That is to say, the heat exchange pipe 241 of the second heat exchanger 24 is coiled around the outer periphery of the compressor 22, and there is a gap between the heat exchange pipe 241 and the compressor 22.

[0089] Since the compressor 22 vibrates during operation, if the heat exchange pipe 241 of the second heat exchanger 24 is placed directly close to the outer periphery of the compressor 22, it will cause resonance between the heat exchange pipe 241 and the compressor 22. Therefore, the existence of the first preset gap M can reduce the direct contact between the heat exchange pipe 241 and the compressor 22, thereby avoiding resonance between the heat exchange pipe 241 and the compressor 22, preventing damage to the heat exchange pipe 241. Furthermore, the existence of the first preset gap M can also avoid heat loss caused by heat conduction between the heat exchange pipe 241 and the compressor 22 due to their close proximity, which helps to reduce thermal resistance and improve heat exchange efficiency.

[0090] Optionally, the first preset gap M between the heat exchange pipe 241 and the compressor 22 is 20-25mm. When the first preset gap M is less than 20mm, the compressor 22 will vibrate during operation. When the first preset gap M is less than 20mm, the compressor 22 and the heat exchange pipe 241 will resonate due to contact, which will generate noise. In severe cases, it will damage the compressor 22 and the heat exchange pipe 241. Furthermore, the first preset gap M of less than 20mm will cause friction and collision between the heat exchange pipe 241 and the compressor 22, which will wear down the compressor 22 and the heat exchange pipe 241, thereby affecting the reliability and operating quality of the integrated air conditioner 100.

[0091] When the first preset gap M is greater than 25mm, the gap between the compressor 22 and the heat exchange pipe 241 is too large, which will cause the pipe connecting the compressor 22 and the heat exchange pipe 241 to grow longer. On the one hand, a first preset gap M greater than 25mm means that the heat conduction path between the heat exchange pipe 241 and the compressor 22 will be longer, which will reduce the heat exchange efficiency. On the other hand, an excessively large gap requires the use of larger-sized components, which will increase the manufacturing cost of the equipment. At the same time, a first preset gap greater than 25mm will occupy more space, restrict the installation position of other components, make the overall layout less compact, and affect the aesthetics of the integrated air conditioner 100.

[0092] Taking a first preset gap M of 20mm as an example, a first preset gap M of 20mm allows the heat exchange pipe 241 to fit more tightly against the outer periphery of the compressor 22, thereby saving space and reducing the size of the integrated air conditioner 100. Furthermore, a first preset gap of 20mm can reduce the flow resistance of the refrigerant in the heat exchange pipe 241 to a certain extent, thus reducing the energy consumption of the integrated air conditioner 100. Taking a first preset gap M of 25mm as an example, a first preset gap M of 25mm provides more support space for the heat exchange pipe 241, helping to reduce deformation or damage to the heat exchange pipe 241 caused by vibration or thermal expansion and contraction. Moreover, during the operation of the compressor 22, its surface temperature may rise. A first preset gap M of 25mm helps to reduce thermal stress caused by temperature differences, thereby extending the service life of the heat exchange pipe 241.

[0093] Furthermore, combined Figure 2 and Figure 3 The heat exchange pipes 241 of the second heat exchanger 24 are coiled to form multiple turns of heat exchange coils arranged in a vertical direction, with adjacent turns of the heat exchange coils being in close contact with each other.

[0094] In this way, on the one hand, the close contact between adjacent heat exchange coils helps to form a continuous heat transfer path, which can reduce heat loss during the transfer process and improve the efficiency and speed of heat transfer; on the other hand, the vertically arranged heat exchange coils can make more effective use of the space of the second receiving cavity 1b, improving the space utilization rate of the second receiving cavity 1b. In addition, by coiling the heat exchange pipe 241 into multiple heat exchange coils, the contact area between the refrigerant pipe 2411 and the water pipe 2412 in the heat exchange pipe 241 can be significantly increased, so that heat can be transferred more effectively from the refrigerant to the cold water, thereby improving the heat exchange efficiency.

[0095] In some embodiments, such as Figure 2 and Figure 4 As shown, the compressor 22 and the water tank 23 are arranged horizontally, and there is a second preset gap N between the heat exchange pipe 241 of the second heat exchanger 24 and the water tank 23. That is to say, there is a gap between the heat exchange pipe 241 of the second heat exchanger 24 surrounding the outer periphery of the compressor 22 and the water tank 23.

[0096] In this way, the existence of the second preset gap N can reduce the direct contact between the heat exchange pipe 241 and the water tank 23, which helps to maintain the stable temperature of the refrigerant in the heat exchange pipe 241, improve the heat exchange efficiency, and avoid potential safety hazards caused by overheating, vibration or leakage due to direct contact between the heat exchange pipe 241 and the side wall of the water tank 23, thus helping to improve the safety and reliability of the integrated air conditioner 100.

[0097] Optionally, the second preset gap N between the heat exchange pipe 241 and the water tank 23 is 20-25mm. When the second preset gap N between the heat exchange pipe 241 and the water tank 23 is less than 20mm, the small gap will restrict airflow, thus affecting heat dissipation performance. This will cause the temperature of the water tank 23 and the heat exchange pipe 241 to rise, affecting the heat exchange efficiency and stability of the refrigerant heat exchange system 2. In addition, a second preset gap N less than 20mm will increase the difficulty of maintenance and inspection of the heat exchange pipe 241 and the water tank 23. When cleaning the water tank 23 or inspecting the heat exchange pipe 241, it may be difficult to operate due to space constraints, thus increasing maintenance costs and time. When the second preset gap N between the heat exchange pipe 241 and the water tank 23 is greater than 25mm, the installation position of the heat exchange pipe 241 and the water tank 23 will occupy more space, reducing space utilization and leading to a further increase in the size of the integrated air conditioner 100, which is not conducive to the need for miniaturization.

[0098] Taking a second preset gap N of 20mm as an example, when the second preset gap N is 20mm, it satisfies the requirement of sufficient airflow space between the heat exchange pipe 241 and the water tank 23, which helps with heat dissipation, and also ensures that the placement of the heat exchange pipe 241 and the water tank 23 makes effective use of space, which can further reduce the size of the integrated air conditioner 100. Taking a second preset gap N of 25mm as an example, when the second preset gap N is 25mm, while ensuring that the size of the integrated air conditioner 100 is small, it provides a larger space for thermal expansion and contraction of the heat exchange pipe 241 and the water tank 23, which can prevent the heat exchange pipe 241 and the water tank 23 from directly contacting each other due to thermal expansion. Under conditions of large temperature changes, it helps to prevent damage or performance degradation caused by thermal expansion and contraction.

[0099] In some embodiments, combined with Figure 1 and Figure 6 The housing 1 includes a lower housing 12, and the second receiving cavity 1b is located inside the lower housing 12.

[0100] The housing 1 also includes an upper housing 11, which is located above the lower housing 12. The first receiving cavity 1a is located inside the upper housing 11. The upper housing 11 has an air outlet 11a and an air inlet 11b, both of which are connected to the first receiving cavity 1a.

[0101] In this way, by placing the first receiving cavity 1a and the second receiving cavity 1b in the lower housing 12 and the upper housing 11 respectively, space can be utilized more effectively, making the overall structure of the housing 1 more compact. Furthermore, the separate design of the upper housing 11 and the lower housing 12 simplifies installation and maintenance. In addition, placing both the air outlet 11a and the air inlet 11b in the upper housing 11 ensures a complete appearance for the lower housing 12, improving the aesthetic appeal of the housing 1 of the integrated air conditioner 100.

[0102] It should be understood that the arrangement of the air outlet 11a and the air inlet 11b is not limited to being located on the upper housing 11 as described in the above embodiment. It can also be that both the air outlet 11a and the air inlet 11b are located on the lower housing 12, or one of the air outlet 11a and the air inlet 11b is located on the upper housing 11 and the other is located on the lower housing 12. This embodiment does not make specific limitations on this.

[0103] Furthermore, such as Figure 1 and Figure 6As shown, the air outlet 11a and the air inlet 11b are located on the same side of the upper housing 11. This simplifies the airflow path within the housing 1, allowing air to enter and exit the housing 1 more directly, reducing unnecessary turns and turbulence, thus improving ventilation efficiency. Furthermore, having the air outlet 11a and air inlet 11b on the same side reduces the size of the integrated air conditioner 100, facilitating miniaturization. Additionally, placing the air outlet 11a and air inlet 11b on the same side makes the housing 1 appear cleaner and neater. This design enhances the overall aesthetics of the integrated air conditioner 100, meeting users' aesthetic requirements.

[0104] It is understandable that the fact that the air outlet 11a and the air inlet 11b are located on the same side of the upper housing 11 means that the air outlet 11a and the air inlet 11b are both located on the left side of the upper housing 11, or that the air outlet 11a and the air inlet 11b are both located on the right side of the upper housing 11, or that the air outlet 11a and the air inlet 11b are both located on the front of the upper housing 11.

[0105] In some embodiments, such as Figure 2 and Figure 3 As shown, the water tank 23 is provided with an overflow port 23a, which is used to allow water to flow out when the water level in the water tank 23 is too high.

[0106] The integrated air conditioner 100 also includes a water collection device 3, which is located in the second receiving cavity 1b and is disposed on the lower side of the water tank 23. The overflow port 23a of the water tank 23 is connected to the water collection device 3.

[0107] That is to say, the integrated air conditioner 100 also includes a water collection device 3 located below the water tank 23, which is connected to the overflow port 23a of the water tank 23.

[0108] In this way, on the one hand, the integrated air conditioner 100 is equipped with a water collection device 3. When the water level in the water tank 23 exceeds the preset height, the excess water can flow into the water collection device 3 through the overflow port 23a of the water tank 23, thereby preventing the water tank 23 from being damaged by overflow or causing other safety hazards. This helps to ensure the normal operation of the integrated air conditioner 100 and prevents potential risks such as short circuits and electric leakage caused by water overflow from the water tank 23. On the other hand, placing the water collection device 3 on the lower side of the water tank 23 makes full use of the space of the second receiving cavity 1b to a certain extent, eliminating the need for a separate space for the water collection device 3, and further reducing the size of the integrated air conditioner 100 to a certain extent.

[0109] Furthermore, such as Figure 5 and Figure 6As shown, a water receiving tray 4 is provided on the lower side of the first heat exchanger 21. The water receiving tray 4 is connected to the water collecting device 3 and is used to collect the condensate flowing out of the first heat exchanger 21.

[0110] In this way, the condensate tray 4 ensures that the condensate flowing from the first heat exchanger 21 is effectively collected, preventing it from dripping directly onto other components or the ground, thus avoiding damage or safety hazards. Furthermore, by connecting the condensate tray 4 to the water collection device 3, the condensate can be smoothly discharged into the water collection device 3 for further treatment or reuse, which helps improve the stability and reliability of the system. Simultaneously, the timely collection and discharge of condensate into the water collection device 3 by the condensate tray 4 prevents condensate from accumulating under the first heat exchanger 21. When the condensate volume is large, the condensate tray 4 can hold a certain amount and discharge it promptly through the connecting pipe to the water collection device 3, helping to prevent condensate from overflowing and causing unnecessary losses or safety hazards.

[0111] Furthermore, combined Figure 5 and Figure 6 The water receiving tray 4 has a first end close to the first heat exchanger 21 and a second end away from the first heat exchanger 21, with the first end higher than the second end, so as to guide the condensate from the first heat exchanger 21 into the water collecting device 3.

[0112] Because the first end of the drip tray 4 is higher than the second end, condensate will naturally flow from the first end to the second end under the influence of gravity. This ensures that the condensate can flow smoothly along the inclined surface of the drip tray 4 without accumulating below the first heat exchanger 21, thereby reducing the risk of system performance degradation or failure due to condensate accumulation. Furthermore, the flow path of the condensate on the drip tray 4 is optimized from high to low, allowing the condensate to flow into the water collection device 3 more quickly, improving drainage efficiency. The inclined drip tray 4 also helps prevent condensate from overflowing. Even in the event of a large amount of condensate production, the condensate can quickly flow to the second end of the drip tray 4 and be discharged into the water collection device 3, thus avoiding the risk of overflow and leakage.

[0113] In some embodiments, combined with Figures 1 to 3 The side of the housing 1 is also provided with a drain outlet 1c, which is used to drain the water inside the integrated air conditioner 100.

[0114] The integrated air conditioner 100 also includes a drain pump 5, the inlet of which is connected to the water collection device 3, and the outlet of which is connected to the drain outlet 1c on the side of the housing 1. The drain pump 5 is used to drain the water in the water collection device 3.

[0115] In this way, the drain pump 5 can actively extract water from the water collection device 3 and quickly discharge it into the external environment through the drain port 1c on the side of the housing 1. Especially when the water volume is large or rapid drainage is required, the drain pump 5 can improve drainage efficiency. Furthermore, the design of the drain pump 5 makes the drainage process more controllable and reliable, reducing safety hazards caused by poor drainage or leakage.

[0116] Furthermore, such as Figure 2 As shown, the integrated air conditioner 100 also includes a water level monitoring module 6, which is installed on the water collection device 3 and is electrically connected to the drainage pump 5. The water level monitoring module 6 is used to monitor the water level of the water collection device 3.

[0117] In this way, by setting up the water level monitoring module 6, the water level changes in the water collection device 3 can be monitored in real time. When the water level reaches a preset threshold, the water level monitoring module 6 will send an electrical signal to cause the drainage pump 5 to start draining water. Through real-time monitoring and automated drainage control, the water level monitoring module 6 can effectively prevent water from overflowing from the water collection device, avoiding damage to the system or causing safety hazards. Furthermore, after the water level monitoring module 6 is electrically connected to the drainage pump 5, this automated drainage control can adjust the working state of the drainage pump 5 according to actual needs, avoiding unnecessary energy consumption and improving the overall energy efficiency of the system.

[0118] It should be noted that the water level monitoring module 6 can be a pressure water level sensor, an optical liquid level sensor, a float liquid level sensor, a resistive liquid level sensor, or a non-contact liquid level sensor. The non-contact liquid level sensor can be a capacitive liquid level sensor or an ultrasonic liquid level sensor. This embodiment does not make specific limitations on this.

[0119] For example, the water level monitoring module 6 is a float-type liquid level sensor. This sensor converts changes in the float's height into changes in an electrical signal, which is then used by relevant demodulation equipment to calculate the liquid level, ensuring the accuracy of the measurement results. Furthermore, the float-type liquid level sensor has a fast response speed, enabling real-time measurement of liquid level changes and timely control and adjustment through the output signal. In addition, the float-type liquid level sensor has a relatively simple structure, mainly composed of a float, a rod, and a sensor, making it easy to manufacture and install. Simultaneously, the float-type liquid level sensor is not easily affected by external factors during use, such as atmospheric temperature, pressure, and humidity, exhibiting high reliability and further ensuring the accuracy of water level monitoring.

[0120] In some embodiments, combined with Figures 1 to 3 The side of the shell 1 is also provided with a cold water inlet 1d, which is connected to the water pipe 2412 of the second heat exchanger 24. The cold water inlet 1d is used to supply cold water to the water pipe 2412 of the second heat exchanger 24.

[0121] The integrated air conditioner 100 also includes a solenoid valve 7, which is located between the chilled water inlet 1d and the water pipe 2412 of the second heat exchanger 24 to control the flow rate of chilled water.

[0122] In this way, the regulating function of solenoid valve 7 allows the refrigerant heat exchange system 2 to adapt to different operating conditions and load changes. Under low load conditions, the chilled water flow rate can be reduced to lower energy consumption; under high load conditions, the chilled water flow rate can be increased to meet cooling demands. Solenoid valve 7 precisely controls the chilled water flow rate entering the second heat exchanger 24, thereby ensuring optimal energy efficiency ratios under different operating conditions. By adjusting the chilled water flow rate, the cooling effect of the refrigerant heat exchange system 2 can be optimized, reducing unnecessary energy consumption.

[0123] It should be noted that, in addition to the above embodiment where a solenoid valve 7 is installed between the cold water inlet 1d and the water pipe 2412 of the second heat exchanger 24 to regulate the cold water flow, a pressure control valve can also be installed to regulate the cold water flow, or other devices capable of regulating the cold water flow can be installed. This embodiment does not specifically limit this.

[0124] It is understood that the solenoid valve 7 in this embodiment can be one or more. The cold water flow rate can be adjusted and the cold water flow can be controlled by connecting multiple solenoid valves 7 in parallel. This embodiment does not make specific limitations in this regard.

[0125] In some embodiments, such as Figure 3 As shown, the integrated air conditioner 100 also includes a throttling device 8, which is disposed between the refrigerant line 2411 of the second heat exchanger 24 and the first heat exchanger 21. The throttling device 8 is used to throttle the refrigerant.

[0126] In this way, the throttling device 8, by throttling the refrigerant, can change the refrigerant to a low-temperature, low-pressure state, controlling the flow rate and pressure of the refrigerant in the refrigerant heat exchange system. This optimizes the cooling effect of the refrigerant heat exchange system, which helps improve the energy efficiency ratio, making the integrated air conditioner 100 more energy-efficient during operation. Furthermore, during the operation of the integrated air conditioner 100, changes in the external environment or fluctuations in the internal load of the system may cause changes in the pressure and temperature within the refrigerant heat exchange system 2. The throttling device 8 can effectively regulate the pressure and temperature inside the refrigerant heat exchange system 2 through its throttling effect, maintaining the stable operation of the refrigerant heat exchange system 2.

[0127] It is understood that the throttling device 8 can be a capillary tube, an electronic expansion valve, or other devices capable of regulating refrigerant pressure; this embodiment does not specifically limit this. For example, when the throttling device 8 is a capillary tube, the refrigerant flow rate and pressure will change accordingly due to the sudden change in the inner diameter of the pipe as the refrigerant passes through it, enabling precise control of the refrigerant flow rate and pressure. Furthermore, the capillary tube has a simple structure and low manufacturing cost, which simplifies the structure of the integrated air conditioner 100 and reduces manufacturing costs.

[0128] Below, we will combine Figure 7 The operating principle of the integrated air conditioner 100 according to the embodiments of this application will be briefly described as follows:

[0129] When the integrated air conditioner 100 is running, the solenoid valve 7 opens, and chilled water enters the water heat exchange system from the chilled water inlet 1d. After passing through the solenoid valve 7, it enters the second heat exchanger 24. The compressor 22 compresses the refrigerant and outputs high-temperature, high-pressure gaseous refrigerant, which enters the second heat exchanger 24 through the refrigerant inlet of the first heat exchanger 21. In the second heat exchanger 24, the heat from the refrigerant is transferred to the water, turning it into liquid refrigerant. The refrigerant, having released its heat, flows out through the refrigerant outlet of the second heat exchanger 24. Then, after being throttled by the throttling device 8, it becomes low-temperature, low-pressure liquid refrigerant and is transported back to the first heat exchanger 21. In the first heat exchanger 21, the refrigerant absorbs heat from the passing air, becoming low-temperature gaseous refrigerant and returning to the compressor 22. In the second heat exchanger 24, the chilled water absorbs heat from the high-temperature refrigerant, becoming hot water. The hot water first enters the water tank 23. When a user uses hot water, the hot water is delivered to the user's water-using device through the hot water outlet and hot water output port of the water tank. When the user is not using hot water, hot water enters the water tank 23 and is stored there. When the water level in the water tank 23 reaches the overflow port 23a, the hot water flows through the overflow port 23a to the water collection device 3, and is subsequently pumped out through the drain pump 5 and discharged from the drain port 1c. By setting up the water tank 23, on the one hand, the condensation waste heat is recovered, achieving the effect of water and energy saving; on the other hand, it enables real-time hot water supply during operation, while storing hot water so that the kitchen hot water needs can be met even when the integrated air conditioner 100 is not running. The solenoid valve 7 can adjust the water flow rate, and in conjunction with the refrigerant heat exchange cycle, it can indirectly adjust the hot water output temperature and the refrigerant outlet temperature. When the user uses hot water, the water flow rate adjustment can keep the hot water output temperature within the human body's comfortable range. When the user does not use hot water, the water flow rate adjustment can enhance the heat exchange efficiency of the second heat exchanger 24, making the refrigerant heat exchange system 2 more efficient and the cold air output stronger.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
