Description

Technical Field

[0001] This utility model relates to the technical field of integrated air conditioners, specifically to an integrated air conditioner with condensate recirculation function. Background Technology

[0002] An all-in-one air conditioner is a device used to regulate temperature. This device is suitable for equipment rooms of various mobile communication operators, research institutes, hospitals, enterprises and other units. With the continuous development of technology, the size of these all-in-one air conditioners is gradually shrinking, so they are no longer limited to commercial use. Some all-in-one air conditioners for home use have also begun to appear on the market.

[0003] The aforementioned integrated household air conditioners are mainly used in smaller spaces such as kitchens and bathrooms. Air conditioners used in kitchens are mainly used for cooling in the summer, and their main usage time is often less than half a year. Therefore, compared with fixed, non-removable wall-mounted air conditioners, integrated air conditioners are more flexible and can be moved according to the user's needs.

[0004] Chinese patent ZL202420881119.3 discloses: "An integrated air conditioner, comprising: a shell, the shell forming an indoor air intake zone and an indoor air supply zone; a fan volute, the fan volute being disposed within the installation space enclosed by the shell, the fan volute forming a receiving space, an air inlet zone, and an air outlet zone, the receiving space for accommodating an indoor fan, the air inlet zone and the air outlet zone being connected through the receiving space so that airflow entering through the indoor air intake zone and the air inlet zone is guided by the fan volute to the air outlet zone and the indoor air supply zone; and a liquid storage container, the liquid storage container for storing humidifying liquid, the liquid storage container being disposed on the bottom side of the fan volute, and the liquid inlet of the liquid storage container being connected to the receiving space so that liquid injected from the indoor air supply zone is guided by the fan volute to the liquid storage container. When it is necessary to replenish water to the liquid storage container, no additional operation of the container is required; water can be added directly from the indoor air supply zone to the shell, greatly facilitating the replenishment operation of the liquid storage container."

[0005] When considering solutions including those in the aforementioned patents, existing integrated air conditioners on the market all share a problem: the evaporator works by using refrigerant to absorb heat from the air, thus cooling the air and creating cool air. During this process, moisture in the air is heated and changes form as it passes through the evaporator, eventually forming condensate on its surface. If this condensate is not drained promptly, it can easily cause frost to form inside the machine. Additionally, the condensate can drip from inside the machine, affecting the user environment. Therefore, existing integrated air conditioners on the market typically include an additional condensate drain structure to drain the condensate separately, but this increases the overall size of the integrated air conditioner. Summary of the Invention

[0006] In order to overcome the shortcomings of existing integrated air conditioners that require a condensate drain structure to discharge condensate separately, which leads to an increase in the overall size of the machine, this utility model provides an integrated air conditioner with a condensate recirculation function.

[0007] The technical solution of this utility model to solve its technical problem is: an integrated air conditioner with condensate recirculation function, comprising:

[0008] The housing has an air inlet and an exhaust outlet.

[0009] A refrigeration assembly disposed within a housing and comprising at least a compressor, a heat exchanger, and an evaporator, wherein the evaporator is located inside the air inlet;

[0010] The refrigeration assembly also includes refrigerant pipelines and liquid pipelines. The compressor, heat exchanger, and evaporator are interconnected through refrigerant pipelines to achieve refrigerant circulation. The heat exchanger is connected to an external liquid source through liquid pipelines to achieve liquid circulation.

[0011] The refrigeration assembly also includes a condensate pipe; one end of the condensate pipe is connected to the evaporator, and the other end is connected to the liquid pipeline, so that the condensate discharged from the evaporator can enter the liquid circulation in the liquid pipeline through the condensate pipe.

[0012] Furthermore, a water receiving base is provided below the evaporator, and a water receiving groove is opened on the upper side of the water receiving base. The lower end of the evaporator is embedded in the water receiving groove. The water outlet is located near the lower end of the evaporator. A connecting pipe hole is also opened at the bottom of the water receiving groove. One end of the condensate pipe is connected to the connecting pipe hole to realize the connection between the condensate pipe and the water receiving groove.

[0013] Furthermore, a guide groove is recessed at the bottom of the water receiving trough, and the connecting pipe hole is opened at the bottom of the guide groove; a guide ramp is also provided at the bottom of the water receiving trough, the guide ramp is connected to one side of the guide groove, and the guide ramp gradually slopes downward towards the connecting pipe hole.

[0014] Furthermore, a connecting post is protruding from the lower side of the water receiving base, and the connecting hole is opened through the connecting post. One end of the condensate pipe is sleeved on the connecting post to achieve connection with the connecting hole.

[0015] Furthermore, several limiting ribs are also provided on the surrounding walls of the water receiving tank. The limiting ribs can abut against the outer surface of the evaporator to prevent the evaporator from moving laterally relative to the water receiving tank. The lower end of the evaporator abuts against the bottom of the water receiving tank, and the upper end of the evaporator abuts against the inner wall of the shell, thereby preventing the evaporator from moving longitudinally relative to the water receiving tank.

[0016] Furthermore, the bottom of the water receiving tank is provided with several supporting protrusions, and the lower end of the evaporator abuts against the supporting protrusions, so that a water passage gap can be formed between the lower end of the evaporator and the bottom of the water receiving tank, and the condensate can flow in the water receiving tank through the water passage gap.

[0017] Furthermore, the refrigeration assembly also includes a condensate pump, and the condensate pipe includes an inlet pipe and an outlet pipe. The inlet pipe is connected between the evaporator and the condensate pump, and the outlet pipe is connected between the heat exchanger and the condensate pump.

[0018] Furthermore, the evaporator includes an evaporator tube and a fin assembly wrapped around the outside of the evaporator tube, and both ends of the evaporator tube are connected to refrigerant piping.

[0019] Furthermore, the heat exchanger includes a plurality of heat exchange tubes, each heat exchange tube being provided with an inlet and an outlet. Both the inlet and outlet of the heat exchange tube are connected to a liquid pipeline, and the other end of the condensate tube is connected to either the inlet or outlet of one of the heat exchange tubes to achieve communication between the condensate tube and the liquid pipeline.

[0020] Furthermore, the heat exchange tube includes a starting heat exchange tube, an intermediate heat exchange tube, and a ending heat exchange tube, wherein the other end of the condensate tube is connected to the liquid outlet of the intermediate heat exchange tube.

[0021] The refrigeration principle of this invention is as follows:

[0022] The refrigerant used to cool the air circulates within the refrigeration unit. First, the gaseous refrigerant is pressurized and heated by the compressor. Then, the gaseous refrigerant enters the heat exchanger through the refrigerant lines. In the heat exchanger, the gaseous refrigerant exchanges heat and releases heat, becoming liquid. Finally, the low-temperature, low-pressure liquid refrigerant enters the evaporator through the refrigerant lines to absorb heat from the air at the air inlet, thus lowering the air temperature at the inlet. The liquid refrigerant, having absorbed heat in the evaporator, reverts to a gaseous state and finally flows back to the compressor through the refrigerant lines. This entire refrigeration process... The heat exchange process of gaseous refrigerant in the intermediate heat exchanger is as follows: external liquid first enters the end heat exchange tube through the liquid pipeline, and exchanges heat with the refrigerant that is about to leave the end heat exchange tube and enter the evaporator. After absorbing heat in the end heat exchange tube, the liquid enters the intermediate heat exchange tube through the liquid pipeline to exchange heat with the refrigerant inside. Then, the refrigerant that has absorbed a lot of heat enters the starting heat exchange tube through the liquid pipeline to absorb heat from the refrigerant that just entered the heat exchanger to achieve pre-cooling. Finally, the liquid leaving the heat exchanger is discharged through the liquid pipeline.

[0023] The condensate recirculation process of this utility model:

[0024] Firstly, during the process of the evaporator absorbing heat from the air through the refrigerant, the water seal in the air adheres to the evaporator and forms condensate. This condensate flows down from the evaporator and into the water collection tank of the water receiving base. The condensate in the water collection tank is then guided by the guide ramp to gather in the guide groove. The condensate in the guide groove is then discharged from the water collection tank through the connecting pipe hole into the condensate pipe. The condensate in the condensate pipe is then transported to the liquid outlet of the intermediate heat exchange tube by the action of the condensate pump, where it merges with the liquid that has just left the intermediate heat exchange tube. The condensate can then enter the initial heat exchange tube along with the liquid to participate in its cooling process of the refrigerant. Finally, after the heat exchange with the refrigerant is completed, the condensate that has been used can be discharged from the liquid pipeline to the outside of the machine along with the liquid.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. The evaporator and liquid pipeline are connected by a condensate pipe, so that the condensate formed on the surface of the evaporator can enter the liquid pipeline through the condensate pipe. This not only allows the condensate to be discharged from the machine with the liquid through the liquid pipeline without the need for a separate condensate discharge pipeline, but also enables the condensate to participate in the heat exchange process of the heat exchanger with the liquid, thus realizing the reuse of the condensate.

[0027] 2. A water collection base is provided to catch the condensate dripping from the surface of the evaporator, and the condensate pipe is also connected to the water collection base, so as to facilitate the collection of dripping condensate and ensure that all condensate can enter the condensate pipe.

[0028] 3. The water receiving base is also provided with limiting ribs and supporting ridges. The limiting ribs can effectively restrict the movement of the evaporator relative to the water receiving base, while the supporting ridges can ensure that there is a gap between the lower end of the evaporator and the bottom of the water receiving base for the flow of condensate.

The evaporator 7 of the refrigeration assembly 4 is located between the air inlet 2 and the air supply assembly 30.

[0053] The cooling principle of this embodiment:

[0054] The refrigerant used for cooling the air circulates within the refrigeration unit 4. First, the gaseous refrigerant is pressurized and heated by the compressor 5. Then, the gaseous refrigerant enters the heat exchanger 6 through the refrigerant pipe 8. In the heat exchanger 6, the gaseous refrigerant exchanges heat and releases heat, becoming liquid. Finally, the low-temperature, low-pressure liquid refrigerant enters the evaporator 7 through the refrigerant pipe 8 to absorb heat from the air at the air inlet 2, thus lowering the air temperature at the inlet 2. The liquid refrigerant, having absorbed heat in the evaporator 7, returns to a gaseous state and finally flows back to the compressor 5 through the refrigerant pipe 8. During this cooling process, heat exchange occurs... The heat exchange process of gaseous refrigerant in heat exchanger 6 is as follows: external liquid first enters the end heat exchange tube 29 through liquid pipe 9, and exchanges heat with the refrigerant that is about to leave the end heat exchange tube 29 and enter the evaporator 7. After absorbing heat in the end heat exchange tube 29, the liquid enters the intermediate heat exchange tube 28 through liquid pipe 9 to exchange heat with the refrigerant therein. Then, the refrigerant that has absorbed a lot of heat enters the starting heat exchange tube 27 through liquid pipe 9 to absorb heat from the refrigerant that just entered the heat exchanger 6 to achieve pre-cooling. Finally, the liquid leaving the heat exchanger 6 is discharged through liquid pipe 9.

[0055] The condensate recirculation process in this embodiment:

[0056] First, during the process of the evaporator 7 absorbing heat from the air through the refrigerant, the water seal in the air will adhere to the evaporator 7 and form condensate. This condensate can flow down from the evaporator 7 and enter the water receiving tank 15 of the water receiving seat 14. The condensate in the water receiving tank 15 can then be guided by the guide ramp 18 to gather in the guide groove 17. The condensate in the guide groove 17 will then be discharged from the water receiving tank 15 through the pipe hole 16 into the condensate pipe 10. The condensate in the condensate pipe 10 is then transported to the liquid outlet 26 of the intermediate heat exchange tube 28 by the action of the condensate pump 22 and merges with the liquid that has just left the intermediate heat exchange tube 28. The condensate can then enter the starting heat exchange tube 27 with the liquid to participate in its cooling process with the refrigerant. Finally, the condensate that has been used after heat exchange with the refrigerant can be discharged from the liquid pipe 9 to the outside of the machine with the liquid.

[0057] The advantages of this embodiment are that it not only achieves the collection and discharge of condensate without the need for a separate condensate drain pipe, but also allows for the reuse of condensate during the discharge process, reducing energy waste.
