[0030] like Figures 1 to 3 As shown, the air conditioning device of the present application includes a gravity cabinet 1, a compressor 2, a first heat exchanger 3 and a second heat exchanger 4. The compressor 2 is connected to the first heat exchanger 3 and the second heat exchanger 4 respectively. The first heat exchanger 3 is located in the gravity cabinet 1, and the first heat exchanger 3 can heat and cool the air flowing through the interior of the gravity cabinet 1. The second heat exchanger 4 is located outside the gravity cabinet 1. The refrigerant of the air conditioning device can circulate between the compressor 2, the first heat exchanger 3 and the second heat exchanger 4.

[0031] In one embodiment, the gravity cabinet 1 is provided with a radiation terminal 11, an inner air outlet group 12, an outer air outlet group 13 and a first accommodating chamber 14. The radiation terminal 11 is located at the front side of the gravity cabinet 1, and the radiation terminal 11 is connected to the second heat exchanger 4. The coolant after heat exchange with the refrigerant in the second heat exchanger 4 can flow into the radiation terminal 11, and then dissipate heat or cold through the radiation terminal 11 to change the indoor ambient temperature and make the indoor environment more comfortable. The radiation terminal 11 assists the gravity cabinet 1 and can change the indoor ambient temperature faster. The second heat exchanger 4 is a plate heat exchanger.

[0032] The inner air vent group 12 and the outer air vent group 13 are respectively located at opposite sides of the gravity cabinet 1, that is, the inner air vent group 12 is located at the front side of the gravity cabinet 1, and the outer air vent group 13 is located at the rear side of the gravity cabinet 1. The inner air vent group 12 and the outer air vent group 13 are both connected to the first accommodating chamber 14, and the external air can enter the first accommodating chamber 14 from the outer air vent group 13 and the inner air vent group 12, and then flow out from the inner air vent group 12.

[0033] The inner air outlet group 12 includes a first inner air outlet 121 and a second inner air outlet 122. The outer air outlet group 13 includes a first outer air outlet 131 and a second outer air outlet 132. The second inner air outlet 122 is located below the first inner air outlet 121 and the first outer air outlet 131, and the second inner air outlet 122 can be respectively connected to the first inner air outlet 121 and the first outer air outlet 131.

The first internal air vent 121, the first external air vent 131 and the second external air vent 132 are all connected to the first accommodating chamber 14, so that the external air enters the first accommodating chamber 14 for heating or cooling, and then flows into the room.

[0036] In the cooling mode of the air conditioner, the first external air vent 131 and the second internal air vent 122 are opened or the first internal air vent 121 and the second internal air vent 122 are opened. Further, when the first external air vent 131 and the second internal air vent 122 are opened, the external air flows through the first heat exchanger 3 from the first external air vent 131, and the external air is cooled and enters the room from the second internal air vent 122, so as to reduce the indoor temperature and perform internal and external air circulation.

[0037] When the first inner air vent 121 and the second inner air vent 122 are opened, the indoor air flows through the first heat exchanger 3 from the first inner air vent 121, and the indoor air is cooled and enters the room again from the second inner air vent 122, thereby accelerating the speed of reducing the indoor temperature and circulating the indoor air.

[0038] In the heating mode of the air conditioning device, the second outer air vent 132 and the first inner air vent 121 are opened or the first inner air vent 121 and the second inner air vent 122 are opened. Further, when the second outer air vent 132 and the first inner air vent 121 are opened, the external air flows through the first heat exchanger 3 from the second outer air vent 132, and the external air is heated and enters the room from the first inner air vent 121, so as to increase the indoor temperature and perform internal and external air circulation.

[0039] When the first inner air vent 121 and the second inner air vent 122 are opened, the indoor air flows through the first heat exchanger 3 from the second inner air vent 122, and the indoor air is heated and enters the room again from the first inner air vent 121, thereby accelerating the indoor temperature increase and performing indoor air circulation.

[0040] When only the radiation terminal 11 is working, the first inner air vent 121 and the second inner air vent 122, the first outer air vent 131 and the second outer air vent 132 can be closed. Specifically, when the air conditioner is in an environment where the air is dry and the air temperature is high or low, the first inner air vent 121, the second inner air vent 122, the first outer air vent 131 and the second outer air vent 132 can be closed, and only the radiation terminal 11 is opened to exchange heat with the environment to further change the ambient temperature.

[0041] The first accommodating chamber 14 is located in the middle area of ​​the gravity cabinet 1 , and the first accommodating chamber 14 is used to accommodate the first heat exchanger 3 .

[0042] In one embodiment, the gravity cabinet 1 is provided with a second accommodating chamber 15, a partition 16 and a third accommodating chamber 17. The air conditioning device includes a third heat exchanger 5, a fourth heat exchanger 6 and an outdoor fan 7. The second accommodating chamber 15 is located below the first accommodating chamber 14 and communicates with the first accommodating chamber 14. The second accommodating chamber 15 is used to accommodate the third heat exchanger 5, and the second accommodating chamber 15 is communicated with the second inner air port 122.

[0043] The partition 16 is located between the first accommodating chamber 14 and the second accommodating chamber 15. Specifically, the partition 16 divides the cavity inside the gravity cabinet 1 into at least the first accommodating chamber 14 and the second accommodating chamber 15. Part of the partition 16 is tilted from top to bottom to guide the liquid condensed in the first accommodating chamber 14 to flow downward, and the partition 16 is also used to guide the gas from the first accommodating chamber 14 to flow to the second accommodating chamber 15.

[0044] The partition 16 includes an upper inclined plate 161 and a lower vertical plate 162. The upper inclined plate 161 is connected to the front side wall of the gravity cabinet 1 and is inclined toward the bottom of the gravity cabinet 1. The lower vertical plate 162 extends from the upper inclined plate 161 to the bottom of the gravity cabinet 1, and the lower vertical plate 162 is spaced apart from the bottom wall of the gravity cabinet 1 so that the first accommodating chamber 14 is connected to the second accommodating chamber 15. The second accommodating chamber 15 is located on the front side of the partition 16, and the first accommodating chamber 14 is located above the partition 16.

[0045] The third accommodating chamber 17 is provided at the front side of the gravity cabinet 1, and the third accommodating chamber 17 is used to accommodate the radiation terminal 11. The third accommodating chamber 17 is recessed backward from the front side wall 101 of the gravity cabinet 1, and the third accommodating chamber 17 is connected to the indoor space to facilitate the radiation terminal 11 to exchange radiation heat or cold. The third accommodating chamber 17 is isolated from the first accommodating chamber 14 to avoid the gas temperature in the third accommodating chamber 17 and the gas temperature in the first accommodating chamber 14 to affect each other.

[0046] The gravity cabinet 1 further includes a water receiving tray 18 and a heat preservation member 19. The water receiving tray 18 is located below the first accommodating chamber 14 and the second accommodating chamber 15, and is provided on the bottom wall of the gravity cabinet 1. The water receiving tray 18 is used to collect the condensed liquid in the first accommodating chamber 14 and the second accommodating chamber 15, and the heat preservation member 19 is located at the rear side of the gravity cabinet 1, and the external air outlet group 13 passes through the heat preservation member 19. Specifically, in the direction from front to back of the gravity cabinet 1, the heat preservation member 19 is located at the rear side of the first accommodating chamber 14.

[0047] The third heat exchanger 5 is located in the second accommodating chamber 15, and the third heat exchanger 5 is in communication with the first heat exchanger 3 and the second heat exchanger 4. The fourth heat exchanger 6 can be in communication with the compressor 2, the first heat exchanger 3, the second heat exchanger 4 and the third heat exchanger 5, respectively. Specifically, in the cooling mode of the air-conditioning device, the fourth heat exchanger 6 is in communication with the third heat exchanger 5. In the heating mode of the air-conditioning device, the fourth heat exchanger 6 can be in communication with the first heat exchanger 3 or the second heat exchanger 4.

[0048] The outdoor fan 7 cooperates with the fourth heat exchanger 6 to assist the fourth heat exchanger 6 in heat exchange.

[0049] In one embodiment, the air conditioning device includes a throttle valve 8, a bypass valve 9, a water pump 10, and a four-way valve 20. The throttle valve 8 can be connected between the first heat exchanger 3 and the third heat exchanger 5, between the first heat exchanger 3 and the fourth heat exchanger 6, or between the second heat exchanger 4 and the fourth heat exchanger 6. Specifically, in the cooling mode of the air conditioning device, the throttle valve 8 is connected between the first heat exchanger 3 and the third heat exchanger 5. In the heating mode of the air conditioning device, the throttle valve 8 is connected between the first heat exchanger 3 and the fourth heat exchanger 6, or between the second heat exchanger 4 and the fourth heat exchanger 6.

[0050] The bypass valve 9 is connected between the fourth heat exchanger 6 and the throttle valve 8. The water pump 10 is connected between the second heat exchanger 4 and the radiation terminal 11 to provide power for the circulation of the secondary coolant. The four-way valve 20 can connect the compressor 2 with the fourth heat exchanger 6, the compressor 2 with the second heat exchanger 4, and the compressor 2 with the first heat exchanger 3.

[0051] The air-conditioning device of the present application is provided with a radiation terminal 11, and the radiation terminal 11 is connected to the second heat exchanger 4, so that when the air-conditioning device is cooling or heating, heat is exchanged with the indoor environment (such as indoor air, human body, furniture, enclosure structure, etc.) through the radiation terminal 11, so that the required ambient temperature can be reached more quickly and the environmental comfort can be improved.

[0052] At the same time, the second inner air vent 122 and the second outer air vent 132 are both located below the first inner air vent 121 and the first outer air vent 131. In the cooling or heating mode of the air conditioning device, the gas flowing through the first accommodating chamber 14 changes its temperature through the first heat exchanger 3, and can circulate by its own characteristics without the need for fan drive (hot gas has a small density and moves upward; cold gas has a high density and moves downward), thereby greatly reducing the noise generated when the gas flows and saving fan energy consumption. At the same time, when the gas circulates, the wind speed is slow and the air is evenly supplied, reducing the feeling of blowing and improving indoor comfort. The gravity cabinet 1 can be set close to the exterior wall, or it can directly replace the exterior wall, reducing the occupation of indoor space and floor height by traditional air conditioning devices and radiant cooling and heating systems.

[0053] In this application, the front-to-back direction of the gravity cabinet 1 is the X-axis direction, and the positive direction of the X-axis points to the front side of the gravity cabinet 1. The up-down direction of the gravity cabinet 1 is the Z-axis direction, and the up-down direction of other components described in this article is also the Z-axis direction. For details, please refer to Figure 2 and Figure 3 .

[0054] The air conditioning device of the present application includes a first cooling mode, a second cooling mode, a first heating mode and a second heating mode. In the first cooling mode, the refrigerant first reaches the fourth heat exchanger 6 from the exhaust port of the compressor 2 through the four-way valve 20 for condensation and heat release. Secondly, the refrigerant enters the third heat exchanger 5 through the one-way valve 30 at the bottom of the gravity cabinet 1 to further release heat to reach a supercooled state, and at the same time heats the air in the second accommodating chamber 15 to prevent the cold air flowing through the second accommodating chamber 15 from condensing or frosting at the second inner air outlet 122, thereby reducing the comfort of personnel when using the air.

[0055] Subsequently, after being throttled by the throttle valve 8, the refrigerant enters the first heat exchanger 3 to evaporate and absorb heat, cooling and dehumidifying the air in the first accommodating chamber 14. Then, the refrigerant enters the second heat exchanger 4 through the three-way valve 40 in the gravity cabinet 1 to continue absorbing heat to an overheated state, while exchanging heat with the coolant in the second heat exchanger 4, thereby reducing the temperature of the coolant in the second heat exchanger 4, and the coolant flows into the radiation terminal 11 to deliver cold air to the room. Finally, the refrigerant flows back to the compressor 2 through the outdoor three-way valve 50 and the four-way valve 20.

[0056] In the second refrigeration mode, the refrigerant first passes through the four-way valve 20 from the exhaust port of the compressor 2 to the fourth heat exchanger 6 for condensation and heat release. Secondly, the refrigerant enters the third heat exchanger 5 through the one-way valve 30 at the bottom of the gravity cabinet 1 to further release heat to reach a supercooled state, and at the same time heats the air in the second accommodating chamber 15 to prevent the cold air flowing through the second accommodating chamber 15 from condensing or frosting at the second inner air outlet 122. Subsequently, after being throttled by the throttle valve 8, the refrigerant enters the first heat exchanger 3 to evaporate and absorb heat, cooling and dehumidifying the air in the first accommodating chamber 14. Finally, the refrigerant returns to the compressor 2 through the three-way valve 40 in the cabinet, the three-way valve 50 outdoors, and the four-way valve 20.

[0057] In the first heating mode, the refrigerant first passes through the four-way valve 20 and the outdoor three-way valve 50 from the exhaust port of the compressor 2 to the second heat exchanger 4 to condense and release heat, and at the same time exchanges heat with the coolant in the second heat exchanger 4, thereby increasing the temperature of the coolant in the second heat exchanger 4, and the coolant flows into the radiation terminal 11 to transport heat to the room. Secondly, the refrigerant enters the first heat exchanger 3 through the three-way valve 40 in the cabinet to further release heat to reach a supercooled state, and at the same time heats the air in the first accommodating chamber 14. Subsequently, after being throttled by the throttle valve 8, the refrigerant enters the fourth heat exchanger 6 from the bypass valve 9 to evaporate and absorb heat to a superheated state. Finally, the refrigerant flows back to the compressor 2 through the four-way valve 20.

[0058] In the second heating mode, the refrigerant first passes through the four-way valve 20 and the outdoor three-way valve 50 from the exhaust port of the compressor 2 to the second heat exchanger 4 to condense and release heat, and at the same time exchanges heat with the secondary coolant in the second heat exchanger 4, thereby increasing the temperature of the secondary coolant in the second heat exchanger 4, and the secondary coolant flows into the radiation terminal 11 to transport heat to the room. Subsequently, the refrigerant enters the throttle valve 8 through the three-way valve 40 in the cabinet, and after throttling by the throttle valve 8, enters the fourth heat exchanger 6 from the bypass valve 9 to evaporate and absorb heat to a superheated state. Finally, the refrigerant flows back to the compressor 2 through the four-way valve 20.

The fifth ventilation mode is a natural wind circulation mode, and is turned on under the condition that the first cooling mode and the second cooling mode, the first heating mode and the second heating mode are all turned off.

[0060] like Figure 4 As shown, in the first ventilation mode, only the second inner air vent 122 and the first outer air vent 131 are opened. Fresh air enters the first accommodating chamber 14 from the first outer air vent 131, and after being cooled and dehumidified by the first heat exchanger 3, it flows into the second accommodating chamber 15 under the action of gravity. Subsequently, the cooled fresh air is reheated by the third heat exchanger 5 and enters the room from the second inner air vent 122.

[0061] like Figure 5 As shown, in the second ventilation mode, only the first inner air vent 121 and the second inner air vent 122 are opened. The indoor air enters the first accommodating chamber 14 through the first inner air vent 121, and after being cooled and dehumidified by the first heat exchanger 3, it flows into the second accommodating chamber 15 under the action of gravity. Subsequently, the cooled fresh air is reheated by the third heat exchanger 5 and enters the room through the second inner air vent 122.

[0063] like Figure 7 As shown, in the fourth ventilation mode, only the first inner air vent 121 and the second inner air vent 122 are opened. Indoor air enters the first accommodating chamber 14 through the second inner air vent 122, and after being heated by the first heat exchanger 3, the high-temperature fresh air flows to the upper part of the first accommodating chamber 14 under the action of gravity, and finally enters the room through the first inner air vent 121.
