[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

"Multiple" generally includes at least two, but does not exclude the case of including at least one.

[0037] It should be understood that the term "and / or" used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0038] It should also be noted that the term "comprises", "comprising", or any other variation thereof is intended to cover a non-exclusive inclusion, such that a commodity or system including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such commodity or system. Without further limitations, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the commodity or system including the said element.

[0039] Currently, due to the complex internal structure of the existing all-in-one air conditioner, the overall size of the outdoor side is relatively large, occupying a large space. After improving the structure of the air conditioner, this application provides an integrated air conditioner without an outdoor fan structure, which fully utilizes the cold energy of the evaporator condensate to cool the inlet of the condensation side through a gravity heat pipe, increasing the temperature difference between the condenser and the inlet; and adding an optional air guide cover to increase the height difference between the inlet and outlet of the condensation side of the unit, making full use of the principle of the chimney effect. Without reducing the heat exchange effect, the overall energy efficiency of the unit can be improved by eliminating the energy consumption of the external fan.

[0040] To further elaborate on the technical solutions in this application, now in combination with Figures 1 - 3 as shown, the following specific embodiments are provided.

[0041] As Figure 1As shown in the figure, in this embodiment, an integrated air conditioner is provided. Part of the integrated air conditioner is located indoors 1, and the other part is located outdoors 2. The air conditioner includes:

[0042] An indoor heat exchanger 8 and an outdoor heat exchanger 7;

[0043] A water receiving tray 13 located below the indoor heat exchanger 8;

[0044] A heat pipe, the heat pipe includes an evaporation part and a condensation part that communicate with each other. The condensation part extends into the water receiving tray 13; the evaporation part extends to the windward side of the outdoor heat exchanger 7.

[0045] In this embodiment, based on the heat pipe, the condensed water can be further utilized, and the outdoor fan is also omitted, solving the problems of many components and inconvenient maintenance of the integrated air conditioner; solving the problems of high energy consumption and low waste cold utilization rate of the condensed water of the integrated air conditioner.

[0046] It should be noted that the heat pipe in this embodiment can also be replaced with a solid structure or not filled with a flowing heat exchange medium. Although the heat exchange effect is slightly worse at this time, it can also realize the pre-cooling treatment of the air on the windward side of the outdoor heat exchanger 7.

[0047] In some alternative ways, the air conditioner further includes:

[0048] A housing, the housing forms an installation space;

[0049] A middle partition 15, the middle partition 15 is arranged in the housing, and the middle partition 15 divides the installation space into an indoor side space and an outdoor side space;

[0050] Wherein the indoor heat exchanger 8 and the water receiving tray 13 are both arranged in the indoor side space; the outdoor heat exchanger 7 is arranged in the housing and located in the outdoor side space; the evaporation part of the heat pipe 14 is located in the outdoor side space, the condensation part of the heat pipe 14 is located in the indoor side space, and the heat pipe connection part connecting the evaporation part and the condensation part penetrates through the middle partition 15.

[0051] Preferably, the heat pipe 14 adopts a return pipe. The return pipe includes: an evaporation pipe section located in the outdoor side space, a condensation pipe section located in the indoor side space, a first communication pipe connecting the first end of the evaporation pipe section and the first end of the condensation pipe section, and a second communication pipe connecting the second end of the evaporation pipe section and the second end of the condensation pipe section. That is, at this time, the first communication pipe and the second communication pipe can be used as the heat pipe connection part, wherein the first communication pipe penetrates through the middle partition 15, and the second communication pipe penetrates through the middle partition 15. The arrangement height of the evaporation pipe section is lower than the arrangement height of the condensation pipe section.

[0052] In some optional ways, an indoor air inlet and an indoor air outlet that are respectively communicated with the indoor-side space are provided on the housing. The indoor air inlet is located at the lower part of the housing, and the indoor air outlet is located at the upper part of the housing. It should be noted that the housing includes an indoor-side panel 12. The indoor air inlet can be provided on the indoor-side panel 12 of the housing, and the indoor air outlet can also be provided at the top of the housing. An outdoor air inlet 3 and an outdoor air outlet 4 that are respectively communicated with the outdoor-side space are provided on the housing. The outdoor air inlet 3 is located at the lower part of the housing, and the outdoor air outlet 4 is located at the upper part or the top of the housing.

[0053] The heat pipe in this embodiment can be provided in an air conditioner with an outdoor fan or can also be used in an air conditioner without an outdoor fan. Since the cooling effect of the heat pipe may not meet the cooling requirements of the outdoor side when the air conditioner does not have an external fan, other cooling components can be used to cool the outdoor-side heat exchanger 7 at this time. The other cooling components can be an air guiding cover 19 or the like.

[0054] Specifically, the air conditioner further includes: an air guiding cover 19. The air guiding cover 19 forms an air guiding channel. The first end of the air guiding channel is communicated with the outdoor air outlet 4, and the second end of the air guiding channel is communicated with the outside atmosphere; wherein the inner diameter of the channel at the first end of the air guiding channel is larger than the inner diameter of the channel at the second end of the air guiding channel. The addition of the air guiding cover 19 can make full use of the chimney effect principle to strengthen the heat transfer on the condensation side without forced convection (fan). Preferably, the air guiding cover 19 is a telescopic multi-section sleeve. The multi-section sleeve includes: n sub-sleeves that are sequentially connected end to end to form the air guiding channel, where n is a positive integer greater than 1. The inner diameter of the (n - 1)th sub-sleeve is larger than the inner diameter of the nth sub-sleeve. The inlet end of the first sub-sleeve is used as the first end of the air guiding channel, and the outlet end of the nth sub-sleeve is used as the second end of the air guiding channel. The cancellation of the outdoor fan and related accessories of the air conditioner facilitates installation and maintenance; at the same time, the air conditioner is equipped with a telescopic air guiding cover 19, which can take into account the installation size and the operating energy consumption of the unit. Without affecting the installation, the height difference between the inlet and outlet of the condensation side is maximized to enhance the heat transfer efficiency.

[0055] It should be noted that the sleeve in this embodiment can be designed in shapes such as flat tubes and round tubes. However, to reduce the friction between the upper and lower layers of metal during telescoping, the air guiding cover 19 can also be preferably designed into a concentric circle structure. At this time, the sleeve is a round tube, that is, when finally exhausting air, it is discharged through the smallest circle in the middle, and the other concentric circles are only for tightly connecting with the surrounding upper and lower layers. As an optional accessory, the air guiding cover 19 can be stretched and adjusted in height at will according to the specific installation situation, with the advantages of strong flexibility and adaptability.

[0056] In this embodiment, the air conditioner further includes an exhaust component. The exhaust component includes an exhaust passage, the first end of the exhaust passage is communicated with the interior, and the second end of the exhaust passage is communicated with the outdoor air inlet 3; an exhaust fan 16 is disposed in the exhaust passage or at the first end of the exhaust passage. The addition of this exhaust component enables the air conditioner to make full use of the indoor exhaust cold energy to cool the unit condenser, and make full use of the power of the exhaust fan and the exhaust cold energy to strengthen the heat exchange on the condensing side.

[0057] Preferably, the outdoor air inlet 3 includes a first air inlet and a second air inlet. The exhaust component further includes a diffuser hood 17, the diffuser hood 17 adopts a cylindrical structure with a gradually expanding outlet, wherein the inlet of the diffuser hood 17 is communicated with the second end of the exhaust passage, and the outlet of the diffuser hood 17 is communicated with the second air inlet; a wind valve 18 is disposed at the second end of the exhaust passage. When there is fresh air and exhaust in the indoor use occasion, this air conditioner can make full use of the cold energy of the exhaust to cool the outdoor heat exchanger 7 and improve the utilization efficiency of waste cold.

[0058] In some alternative ways, the air conditioner further includes a spraying component. Based on the spraying component, the condensed water collected on the indoor side is sprayed onto the outdoor heat exchanger 7 for cooling to further improve the heat exchange effect. This air conditioner can make full use of the high-quality exhaust on the indoor side and the cold energy of the evaporator condensed water to improve the heat exchange efficiency on the condensing side; while canceling the outdoor fan, it also reduces the overall power consumption of the system; and a draft hood 19 with adjustable size is given as an optional accessory, which can be lengthened or telescoped according to the actual engineering installation situation, fully taking into account the size of the actual installation position and the energy consumption of the unit operation. Preferably, the spraying component includes a spray head arranged towards the outdoor heat exchanger 7; a water delivery pipeline 6, one end of the water delivery pipeline 6 is communicated with the water receiving tray 13, and the other end is communicated with the spray head; a water pump and an electromagnetic water valve 11 arranged on the water delivery pipeline 6.

[0059] The integrated air conditioner in this embodiment cancels the outdoor fan without affecting the overall heat exchange efficiency of the unit. This integrated air conditioner can make good use of the indoor exhaust and make full use of the waste cold energy; when there is no fresh air introduced, it can also use the cold energy of the condensed water on the evaporation side of the unit to pre-cool the incoming air on the condensing side in the form of a gravity heat pipe 14. At the same time, this application further increases the height difference between the incoming and outgoing air on the condensing side to better exert the chimney effect. Through the reasonable switching of the above embodiments, while not reducing the overall energy efficiency of the unit, it can also reduce the shell size, reduce the use of important components of the air conditioner, and make maintenance more convenient and other advantages. Through the above method, while facilitating the installation and maintenance of the unit, the shell size of the unit itself is reduced.

[0060] The design and a specific working process of the air conditioner will be described below in combination with other relevant components of the air conditioner.

[0061] Such as Figure 1As shown in the figure, the integrated air conditioner without a blower on the outer side in this embodiment is composed of a compressor, an outdoor heat exchanger 7 (condenser), a throttling mechanism, an indoor blower 9, an indoor heat exchanger 8 (evaporator), a water receiving tray 13, a water pipe 6, a heat pipe 14, an electromagnetic water valve 11, a liquid level gauge, and its supporting sheet metal and pipelines. The part arranged in the outdoor space of the air conditioner mainly consists of a compressor, a condenser, a throttling mechanism, an evaporation part (as the evaporation side part of the heat pipe), a part of the water pipe 6 (extending from the drain outlet of the water receiving tray, the part on the outdoor side), and a part of the supporting sheet metal and pipeline components; while the part located in the indoor space of the air conditioner mainly consists of an evaporator, an indoor blower 9, a water receiving tray 13, an electromagnetic water valve 11 and a liquid level gauge, a condensation part (as the condensation side part of the heat pipe), a part of the water pipe 6 (extending from the drain outlet of the water receiving tray, the part on the indoor side), and an electric control box.

[0062] There is a sheet metal for sealing and partitioning in the middle of the indoor and outdoor sides to ensure that the cooling capacity and air flow on the inside and outside are not affected. There are also a few pipe holes in the middle of the sheet metal for connecting the refrigerant flow paths between the evaporator and the condenser, the flow paths of the evaporation side and the condensation side of the heat pipe, and the pipe hole positions of the water pipe 6 connecting the water receiving tray 13. Considering that these pipe holes need to have good sealing performance, strict caulking treatment must be carried out during installation.

[0063] The indoor evaporator 8 is arranged at the middle height position, and the centrifugal blower on the evaporation side is arranged higher, so the overall indoor air direction is from bottom to top. Because it is considered that the vertical air inlet of the evaporator has relatively high heat exchange efficiency and the air inlet mode of the centrifugal blower. Therefore, the indoor side of the air conditioner generally adopts the form of front upper side air inlet and front lower side air outlet. The water receiving tray 13 is arranged at the lower part of the indoor evaporator, and the condensation side of the heat pipe is arranged at the bottom of the water receiving tray 13 to ensure that the cooling capacity of the condensed water can be used to pre-cool the air input from the outdoor air inlet 3 in the first time. Because the water receiving tray 13 cannot always hold the condensed water, when the condensed water reaches a certain height in the water receiving tray 13 (the upper liquid level gauge above), the electromagnetic water valve on the water pipe 6 connecting the water receiving tray 13 is opened, and the condensed water is directly led to the top of the air conditioner condenser for spraying. In this case, the heat transfer on the condensation side becomes a heat dissipation form similar to spraying water on the heat exchanger, and the heat exchange efficiency is greatly improved. In order not to affect the continuous cooling effect of the heat pipe on pre-cooling the condenser, we must give a lower liquid level gauge height to the water receiving tray 13, that is, when the condensed water in the water receiving tray 13 just passes over the condensation side of the heat pipe, this height generally depends on the diameter of the heat pipe, usually about 10 mm. The water receiving tray 13 drains water until the lower side liquid level gauge, and the electromagnetic water valve 11 closes to stop the drainage process. The water receiving tray 13 continues to collect condensed water until it reaches the upper side liquid level gauge again, then the electromagnetic water valve 11 is opened to start the drainage process, and so on.

[0064] It should be noted that there are two reasons why the above-mentioned condensed water is not directly sprayed onto the condenser of the air conditioner. There is a process of collecting the condensed water of the air conditioner. When the air conditioner is just started, the amount of water directly sprayed is very small, so the heat exchange effect on the condensation side is very poor. More importantly, the water sprayed onto the condenser will quickly evaporate after hitting the surface of the condenser at about 60 °C, generating phase change heat absorption. After evaporation, the water vapor will quickly rise and flow out of the outer top air outlet along with the chimney effect. This results in a very low utilization efficiency of the cold energy of this part of the low-temperature condensed water. In addition, a large part of the water drops to the outside of the outdoor air inlet 3 (including the first air inlet and the second air inlet) immediately after spraying. Therefore, in this embodiment, the heat pipe method is used to fully utilize this part of the temperature difference heat and then spray the condensed water with slightly higher temperature and slightly lower quality to achieve the purpose of fully utilizing the cold energy of the condensed water. At the same time, after the condensed water is discharged through the condenser, it can be seen from the structure that it is directly adjacent to the two outdoor air inlets, so the drainage is relatively smooth; at the same time, if some water droplets adhere to the two air inlets, they will further evaporate after being heated by the temperature difference of the outdoor environment and rise through the condenser, further enhancing the heat exchange effect of the condenser.

[0065] The outdoor condenser is arranged at a lower position, and the evaporation side of the heat pipe is arranged obliquely below the condenser. The outdoor air inlet 3 is located at a lower position on the outdoor side of the air conditioner housing, and through sheet metal diversion, it is ensured that the final air inlet direction is perpendicular to the surface of the condenser. In this embodiment, it is preferably designed with two air inlets on the outdoor side. One air inlet is at the bottom of the housing and is used to suck air by the chimney effect for normal outdoor air utilization. One air inlet (the second air inlet) is opened at a lower position of the outdoor side panel 10 of the housing itself, and this air inlet is the air suction port on the outdoor side when the indoor side turns on the exhaust function. First, the second air inlet opened on the outdoor side panel 10 is directly perpendicular to the air inlet of the condenser, and the second air inlet will only have air entering the outdoor part of the air conditioner when there is exhaust on the indoor side. Therefore, a wind valve 18 structure is provided here. When the indoor exhaust fan starts, the wind valve 18 opens, and the outdoor air inlet is mainly the indoor exhaust. When the indoor fan 9 is closed, the wind valve 18 closes, and at this time, the wind valve 18 is a sealed structure. The air entering from the outdoor bottom will pass through the cavity and be blocked by the top sheet metal and the wind valve 18. All the air will first be pre-cooled by the evaporation side of the heat pipe and then enter the condenser for heat exchange. Because the condenser has a temperature of about 60 °C, plus the incoming air is pre-cooled by the heat pipe, this temperature difference may reach 30 - 40 degrees Celsius. The incoming air is heated by the condenser and then rises to generate a driving force. Coupled with the fact that the air conditioner itself is provided with an air guiding cover 19 to increase the height difference between the outdoor air inlet and outlet of the air conditioner, it is easy to generate the driving force of the chimney effect and change the natural convection into forced convection with a certain driving force. However, considering the vertical position of the evaporator here must be higher than the vertical position of the condenser. Because of the principle of the gravity heat pipe we adopted, the evaporation side of the gravity heat pipe is only at the bottom, and after absorbing heat, it can float to the condensation side of the heat pipe (exchange heat with the condensate water in the water receiving tray) to release heat and then condense and flow down to complete a whole set of cycles. The outdoor air outlet 4 is arranged at the top of the air conditioner, and the purpose is to use it simultaneously with the selected air guiding cover 19 to increase the height difference between the outdoor air inlet and outlet.

[0066] The air guiding cover 19 on the outdoor side is connected to the outdoor part of the air conditioner by means of snap-fasteners or slides. The cross-sectional dimension of the first end of the air guiding channel formed by the air guiding cover 19 is equivalent to the dimension of the outdoor air outlet 4 of the air conditioner. At the same time, the second end of the air guiding channel formed by the air guiding cover is used as the air outlet. The air guiding cover 19 is arranged in a stretchable and retractable structural layout, fully considering whether there is enough space in the actual installation environment of the air conditioner. At the same time, when the space is sufficient, the stretchable air guiding cover 19 accessory is stretched to the longest, which can greatly improve the effect of the chimney effect. Ensure that under the condition of actual installation feasibility, the heat exchange efficiency on the outdoor side is greatly improved. At the same time, because the outdoor fan of the air conditioner is not installed, the actual power consumption of the air conditioner can be reduced, and the operating energy consumption can be further reduced.

[0067] When the independent fresh air system on the indoor side of the air conditioner is working, in order to maintain the pressure balance on the indoor side, a corresponding exhaust fan 16 will lead a part of the wind away. The indoor exhaust pipe can be led to the bottom of the outdoor side of the air conditioner to make full use of the cold air discharged from the indoor side. At the same time, the exhaust fan 16 can just provide the conditions for forced convection heat exchange on the outdoor side of our air conditioner, that is, when the fan is not installed on the outdoor side of the air conditioner, the driving force of the exhaust fan 16 is fully utilized to make the outdoor heat exchanger 7 in a state of forced convection heat exchange, thereby improving the energy consumption of the air conditioner. At this time, the condensed water of the refrigeration system is still being collected, and this part of the condensed water still needs to be discharged. Considering that the air conditioner has an exhaust fan 16 to lead the indoor air flow to the outdoor fan for forced heat exchange, the pre-cooling of the evaporation part of the heat pipe is already negligible. Therefore, at this time, we often open the electromagnetic water valve 11 on the water supply pipeline 6 to directly pass the generated condensed water to the top of the air conditioner condenser to strengthen the heat exchange on the condensation side of the air conditioner.

[0068] In this embodiment, the control logic between some components of the air conditioner is also described.

[0069] 1) When the exhaust fan 16 is started, the outdoor air inlet valve 18 is opened. At this time, the outdoor air intake is mainly provided by the indoor exhaust air, that is, the air is mainly taken in from the air inlet 2. At this time, the electromagnetic water valve 11 remains in a normally open state.

[0070] 2) When the exhaust fan 16 is turned off, the outdoor air inlet valve 18 is closed, and the outdoor air can only enter through the air inlet 1.

[0071] The switch of the electromagnetic water valve is controlled according to the water level of the water receiving tray 13 as follows:

[0072] 1) When the water level in the water tray 13 rises to the height of the upper liquid level gauge, the electromagnetic water valve opens;

[0073] 2) When the water level in the water tray 13 drops to the height of the lower level gauge, the electromagnetic water valve closes.

[0074] Based on the above control logic, the actual water level in the water receiving pan 13 can be controlled between the height of the upper liquid level gauge and the height of the lower liquid level gauge, thereby ensuring that the condensed water will neither overflow the water receiving pan 13 nor be completely discharged to affect the heat exchange of the heat pipe.

[0075] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
