Description

Technical Field

[0001] The present application relates to the field of air-conditioning equipment, and in particular to a refrigeration and dehumidification air-conditioning device. Background Art

[0002] In existing technology, comfort air conditioning systems are categorized by structure into split and integrated units. Integrated units are further divided into portable and fixed units. Fixed units can be further categorized as indoor integrated units, outdoor integrated units, and window units. All three types are primarily used to control ambient temperature and cleanliness, with dehumidification being a secondary function, resulting in limited dehumidification effectiveness. Furthermore, dehumidification lowers the ambient temperature, limiting their practical applications.

[0003] In the prior art, household dehumidifiers are relatively popular and have a significant dehumidification effect under low temperature and high humidity conditions, but they generally cannot be used for refrigeration purposes. Utility Model Content

[0004] In view of this, the present application provides a refrigeration and dehumidification air conditioner, which takes into account the functions of comfort air conditioning and special dehumidifier, and specifically includes: a first shell, wherein the end face of one side of the first shell includes a first air exchange port, a first fan is provided in the first shell corresponding to the first air exchange port, and the upper end face of the first shell includes a second air exchange port; a second shell, one side of the lower end face of the second shell is hinged to one side of the upper end face of the first shell, the upper end face of the second shell includes a third air exchange port, a second fan is provided in the second shell corresponding to the third air exchange port, the lower end face of the second shell includes a fourth air exchange port, the second shell includes at least a first fixed position and a second fixed position relative to the first shell, and the second shell When the body is in the first fixed position, the second air exchange port is fitted with the fourth air exchange port, and when the second shell is in the second fixed position, the second shell is fixed at a certain angle to the first shell; the refrigeration and dehumidification system includes a compressor, the compressor is arranged in the first shell, the compressor is connected to a condenser through a first connecting pipe, the condenser is arranged in the second shell corresponding to the third air exchange port, the condenser is connected to an expansion valve through a second connecting pipe, the expansion valve is arranged in the first shell, the expansion valve is connected to an evaporator through a pipeline, the evaporator is arranged in the first shell corresponding to the second air exchange port, and the evaporator is connected to the compressor through a pipeline.

[0005] With the above-described specific structure, the second housing is hingedly connected to the first housing. When the air conditioner is in the first fixed position, it enters dehumidification mode: the second fan is activated, and air is drawn into the first housing through the first air exchange port due to negative pressure, activating the cooling and dehumidification system. The air passes through the evaporator, where the evaporator coil temperature is lower than the air's dew point, causing water vapor in the air to condense on the evaporator coil, thereby achieving a dehumidification effect. After passing through the evaporator, the air again exchanges heat with the condenser to increase its temperature before being discharged through the third air exchange port. This allows the air conditioner to achieve a dehumidification effect without lowering the ambient temperature. When the air conditioner is in the second fixed position, it enters cooling mode: the second fan is activated, causing air to enter the second housing through the fourth air exchange port and exit through the third air exchange port. The first fan is activated, causing air to enter the first housing through the second air exchange port and exit through the first air exchange port, activating the cooling and dehumidification system. The air passing through the first housing is cooled by the evaporator, while the air passing through the second housing removes heat from the condenser, thereby achieving a cooling effect.

[0006] As a possible implementation, the first shell is a rectangular parallelepiped structure, the second shell is a rectangular parallelepiped structure, and the cross-sections of the first shell and the second shell are the same.

[0007] With the above possible implementation, the cross-sections of the first shell and the second shell are the same, so that when in the first fixed position, the first shell and the second shell can completely overlap, saving placement space.

[0008] As a possible implementation, when the second shell is in the second fixed connection position, the lower end surface of the second shell is fixed at 90 degrees to the upper end surface of the first shell.

[0009] As a possible implementation, a control panel is provided on the side surface of the first shell, and a switch is provided on the control panel. The switch is used to control the compressor, the first fan and the second fan.

[0010] As a possible implementation, a water receiving tray is provided below the evaporator, the water receiving tray is connected to a water storage tank via a water collecting pipe, and the water storage tank is provided in the first shell.

[0022] Below, the specific implementation methods of the present application are described in detail with reference to the accompanying drawings.

[0023] This application provides a refrigeration and dehumidification air conditioner, such as Figure 2As shown, the air conditioner includes a first housing 10 and a second housing 20. The second housing 20 is connected to the upper portion of the first housing 10 via a connecting hinge 30. Furthermore, the refrigeration and dehumidification air conditioner according to the embodiments of the present application also includes a refrigeration and dehumidification system. The refrigeration and dehumidification system is integrated into the first housing 10 and the second housing 20.

[0024] Among them, such as Figure 2 As shown, the first housing 10 includes a first air exchange port 11 at one end surface, and a second air exchange port 12 at the upper end surface. An air filter 800 is provided at the second air exchange port 12 to filter impurities in the air and improve air quality. A first fan 100 is provided in the first housing 10 corresponding to the first air exchange port 11.

[0025] Among them, such as Figure 2 As shown, one side of the lower end surface of the second housing 20 is hingedly connected to one side of the upper end surface of the first housing 10. The upper end surface of the second housing 20 includes a third air exchange port 21, and the lower end surface of the second housing 20 includes a fourth air exchange port 22. A second fan 200 is provided in the second housing 20 corresponding to the third air exchange port 21.

[0026] Among them, such as Figure 3 and 4 As shown, the second housing 20 includes at least a first fixed position and a second fixed position relative to the first housing 10. Figure 3 As shown, when the second housing 20 is in the first fixed position, the second air exchange opening 12 and the fourth air exchange opening 22 are in contact with each other. Figure 4 As shown, when the second shell 20 is in the second fixed position, the second shell 20 and the first shell 10 are fixed at a certain angle.

[0027] In this embodiment, the first housing 10 and the second housing 20 are rectangular parallelepiped structures, with the same cross-section. In the first fixed position, the upper end surface of the first housing 10 is tightly fitted against the lower end surface of the second housing 20. Preferably, a sealing device that is easily removable can be used to seal the joint between the first and second housings 10, 20, thereby preventing air blown out of the second air exchange port 12 from escaping through the gap.

[0028] In this embodiment, if Figure 4 As shown, when the second housing 20 is in the second fixed connection position, the lower end surface of the second housing 20 is fixed at 90 degrees to the upper end surface of the first housing 10. In addition, in other embodiments, the angle between the second housing 20 and the first housing 10 in the second fixed connection position can be adjusted as needed. For example, it can be 60 degrees, 120 degrees, etc.

[0029] In this embodiment, the second housing 20 is connected to the first housing 10 by a hinge. Alternatively, in other embodiments, other connection methods may be used. For example, the first housing 10 and the second housing 20 may be separated by a short distance and connected by a hose, or may be pivotally connected.

[0030] Among them, such as Figure 2 As shown, the refrigeration and dehumidification system includes a compressor 300, which is disposed in a first housing 10. The compressor 300 is connected to a condenser 500 via a first connecting pipe. The condenser 500 is disposed in the second housing 20 at a location corresponding to the third air exchange port 21 and is connected to an expansion valve 400 via a second connecting pipe. The expansion valve 400 is disposed in the first housing 10 and is connected to an evaporator 600 via a pipeline. The evaporator 600 is disposed in the first housing 10 at a location corresponding to the second air exchange port 12 and is connected to the compressor 300 via a pipeline. A water collection pan 610 is disposed below the evaporator 600 and is connected to a water storage tank 700 via a water collection pipe 611. The water collection pan 610 collects condensed water from the evaporator 600, which then flows through the water collection pipe 611 into the water storage tank 700 for storage.

[0031] In this embodiment, a thermal expansion valve is used as the throttling device of the refrigeration and dehumidification system. In addition, in other embodiments, other throttling devices, such as a capillary tube, an electronic expansion valve, etc., may also be used.

[0032] In this embodiment, the compressor 300 is not limited to variable capacity or fixed capacity compressors on the market, and other types of compressors may also be used.

[0033] In this embodiment, if Figure 1 As shown, a control panel 13 is provided on the side surface of the first housing 10 , and switches are provided on the control panel 13 . The switches are used to control the compressor 300 , the first fan 100 and the second fan 200 .

[0034] In this embodiment, the first connecting pipe and the second connecting pipe are both hoses and are integrated into a connecting hose 900. In addition, in other embodiments, other connection methods can be used, for example, a hinged pipe joint structure.

[0035] Among them, such as Figure 2 As shown, the water tank 700 is provided in the first housing 10. A water level switch 710 is provided in the water tank 700, and the water level switch 710 can control the compressor 300, the first blower 100 and the second blower 200. Figure 1As shown, a water tank door 14 is provided on the surface of the first housing 10 at a position corresponding to the water tank 700. A drain outlet 15 is provided on the water tank door 14, and a pipe connects the water tank 700 to the drain outlet 15. When the water level in the water tank 700 reaches a certain height, a water level switch 710 is triggered, which controls the cooling and dehumidifying air conditioner to shut down and sound an alarm, reminding the user to clear the accumulated water.

[0036] In this embodiment, a handle 16 is provided on the water tank door 14, and the water tank 700 is a pull-out design and is arranged in the first housing 10 through a track. In addition, the water tank 700 is made of transparent material, which is convenient for users to observe the water level in the water tank 700.

[0037] In this embodiment, the compressor 300, the first blower 100, and the second blower 200 are powered by a power supply. In addition, in other embodiments, other power supply methods may be used, such as battery power supply, solar power supply, etc.

[0038] In this embodiment, a grille is provided at the first air exchange port 11. A grille is provided at the third air exchange port 21. The grille is used to prevent external objects from contacting the first fan 100 and the second fan 200, thereby protecting the fans and preventing injuries to operators.

[0039] In this embodiment, a plurality of feet are distributed on the lower end of the first housing 10. In addition, in other embodiments, wheels or the like can be used instead of the feet.

[0040] The refrigeration and dehumidification air conditioner involved in the embodiment of the present application includes a dehumidification mode and a refrigeration mode. The refrigeration and dehumidification air conditioner enters the dehumidification mode when it is in the first fixed position. The specific working steps are as follows: the second fan 200 is started, and the air is drawn into the first shell 10 from the first air exchange port 11 due to negative pressure, and the refrigeration and dehumidification system is started; the air passes through the evaporator 600. At this time, the evaporator coil temperature is lower than the dew point temperature of the air, and the water vapor in the air condenses and precipitates on the evaporator coil, thereby achieving the dehumidification effect; after passing through the evaporator 600, the air exchanges heat with the condenser 500 again to increase the temperature, and then is discharged through the third air exchange port 21. In this way, the dehumidification effect can be achieved without lowering the ambient temperature, and the dehumidification needs in an environment with low temperature and high relative humidity can be met.

[0041] The cooling and dehumidifying air conditioner enters cooling mode when in the second fixed position. The specific operating steps are as follows: the first fan 100 starts, air enters the second shell 20 through the fourth air exchange port 22 and is blown out through the third air exchange port 21. The second fan 200 starts, air enters the first shell 10 through the second air exchange port 12 and is blown out through the first air exchange port 11, and the cooling and dehumidifying system is activated. The air passing through the first shell 10 is cooled by the evaporator 600, and the air passing through the second shell 20 removes heat from the condenser 500, thereby achieving a cooling effect. In cooling mode, air enters the first shell 10 and the second shell 20 simultaneously from two directions, increasing the return air area, and the two shells do not interfere with each other during return air.

[0042] In addition, under normal circumstances, the refrigeration and dehumidification air conditioner needs to add an isolation device in the cooling mode to prevent the hot air blown out from the condenser side from flowing back and causing poor cooling effect. For example, in outdoor tents and room windows, isolating the second shell 20 to the outdoors can achieve a temperature drop in the indoor environment, and the cooling effect on the first shell 10 side is better. At the same time, the refrigeration and dehumidification air conditioner can be used directly without additional isolation devices in some scenarios, such as in hot outdoor conditions. At this time, the first fan 100 and the second fan 200 are started, and the compressor 300 is started at the same time. The return air at the first shell 10 is at ambient temperature, and the outlet air is cold air cooled by the evaporator 600. The return air at the second shell 20 is at ambient temperature, and the outlet air is hot air that has passed through the condenser 500. The outlet directions of the cold air and the hot air are opposite to each other, which minimizes the short circuit of the hot air and makes the cooling effect better.

[0043] In summary, the refrigeration and dehumidification air conditioner involved in the embodiment of the present application takes into account both refrigeration and dehumidification functions, and does not cause the ambient temperature to drop during the dehumidification process. In addition, the second shell 20 and the first shell 10 can rotate relative to each other or be used separately, which can make the return air smoother in the cooling mode, improve the heat exchange effect, and thus improve the cooling effect. At the same time, the first fan 100 does not need to be started in the dehumidification mode, making the entire machine more energy-efficient. Finally, the refrigeration and dehumidification air conditioner has an integrated structure, which is easy to install, transport, and use.
