Description

Technical Field

[0001] The present invention relates to the field of heat pump technology, and in particular to a central air-conditioning terminal and a central air-conditioning. Background Technology

[0002] The central air conditioner includes a main unit and a central air conditioner terminal. The central air conditioner terminal includes an air conditioner box, a heat exchanger, a fan and a water tray (or a condensed water receiving component). The side of the air conditioner box has an air inlet; the heat exchanger, the fan and the water tray are arranged in the air conditioner box; the heat exchanger is arranged at the air inlet; the water tray is located below the heat exchanger and is used to receive the condensed water from the heat exchanger. The water tray has a drainage hole, which is used to discharge the condensed water to the outside.

[0003] In the prior art, the heat exchanger is covered at the air inlet to facilitate heat exchange; for example, in the cooling mode, the hot air from the outdoor environment is heat-exchanged with the heat exchanger at the air inlet of the air conditioner under the action of the fan, and then flows to the indoor environment, that is, the hot air from the outdoor environment becomes cold air after heat exchange with the heat exchanger.

[0004] However, the heat exchanger is an integral structure. In order to improve the heat exchange performance, the heat exchanger is usually larger in size. A larger heat exchanger is installed at the air inlet on the side (single side) of the air conditioner box, which will "expand" the air conditioner box. In other words, a larger air conditioner box is required to accommodate the heat exchanger, which results in a larger space occupied by the central air conditioner terminal and a heavier weight. In addition, the condensed water received by the water tray is usually directly discharged through the sewer pipe, which leads to the technical problem of not fully utilizing the condensed water.

[0017] By respectively arranging a heat exchanger (the first heat exchanger and the second heat exchanger) on different sides (the first side and the second side) of the air - conditioning box body, rather than only arranging a larger heat exchanger on one side. That is, the present invention installs a smaller heat exchanger on different sides of the air - conditioning box body. Compared with the prior art, the present invention can set the area of one side of the air - conditioning box body to be smaller, without the need to set a larger - sized air - conditioning box body. By setting a relatively smaller - sized air - conditioning box body, the first heat exchanger and the second heat exchanger can be accommodated. Therefore, it can reduce the space occupied by the central air - conditioning terminal and reduce the load on the roof. And, the condensed water received by the condensed - water receiving component will flow through the lamp. Since the temperature of the condensed water is relatively low, after the condensed water flows through the lamp, it will take away the heat of the lamp and dissipate heat for the lamp, so as to make full use of the condensed water. It solves the technical problems of large space occupied by the central air - conditioning terminal and insufficient utilization of condensed water in the prior art. Description of the Drawings

[0030] Figures 1 to 3 The central air-conditioning terminal and the central air-conditioning provided by the present invention are shown. It can be seen from the figure that the central air-conditioning terminal of the present invention includes an air-conditioning box body 100, a first heat exchanger 200, a second heat exchanger 300, a lamp 400 and a condensate receiving member 500; the air-conditioning box body 100 has an inner cavity 150, a first air inlet 111 and a second air inlet 112; the first air inlet 111 and the second air inlet 112 can communicate with the inner cavity 150; the first air inlet 111 is located on the first side 130 of the air-conditioning box body 100; the second air inlet 112 is located on the second side 140 of the air-conditioning box body 100; the first heat exchanger 200 is arranged in the inner cavity 150 and is located at the first air inlet 111; the second heat exchanger 300 is arranged in the inner cavity 150 and is located at the second air inlet 112; the lamp 400 is connected to the air-conditioning box body 100, and the lamp 400 has a liquid cooling channel; the liquid cooling channel has a channel inlet; the condensate receiving member 500 has a water receiving cavity and a drain hole that can communicate with the water receiving cavity; the water receiving cavity is located below the first heat exchanger 200 and / or the second heat exchanger 300; the drain hole communicates with the channel inlet.

[0031] In specific implementation, by respectively arranging a heat exchanger (a first heat exchanger 200 and a second heat exchanger 300) on different sides of the air-conditioning box body 100, rather than arranging a larger heat exchanger on only one side, that is, in the present invention, a smaller heat exchanger is respectively installed on different sides of the air-conditioning box body 100. Compared with the prior art, in the present invention, the area of one side of the air-conditioning box body 100 can be set smaller, and there is no need to set a larger-sized air-conditioning box body 100. By setting a relatively smaller-sized air-conditioning box body 100, the first heat exchanger 200 and the second heat exchanger 300 can be accommodated. Therefore, the space occupied by the end of the central air conditioner can be reduced, and the load on the roof can be alleviated; and, the condensed water received by the condensed water receiving component 500 will flow through the lamp 400. Since the temperature of the condensed water is relatively low, after the condensed water flows through the lamp 400, the heat of the lamp 400 will be taken away, and the lamp 400 is cooled, so as to make full use of the condensed water; the technical problems of large space occupied by the end of the central air conditioner and insufficient utilization of condensed water in the prior art are solved.

[0032] In this embodiment, the air-conditioning box body 100 can be integrally in a "T" shape; the air-conditioning box body 100 can be set as a hollow structure and can be formed by sheet metal fabrication; the first air inlet 111 and the second air inlet 112 can be arranged opposite to each other horizontally, that is, the first side 130 can be the left side of the air-conditioning box body 100, and the second side 140 can be the right side of the air-conditioning box body 100; the air outlet 122 can be located on the two horizontal sides at the bottom of the air-conditioning box body 100; the first heat exchanger 200, the second heat exchanger 300 and the lamp 400 can be of the prior art; the lamp 400 can be a light-emitting diode; the condensed water receiving component 500 can also be called a water receiving tray. The condensed water receiving component 500 is equivalent to a container for receiving condensed water. There can be two condensed water receiving components 500. One condensed water receiving component 500 is located below the first heat exchanger 200 for receiving the condensed water of the first heat exchanger 200; the other condensed water receiving component 500 can be located below the second heat exchanger 300 for receiving the condensed water of the second heat exchanger 300.

[0033] According to an embodiment of the present invention, the air-conditioning box body 100 has at least one air outlet 122, and at least one air outlet 122 is located in the internal space of the building.

[0034] In specific implementation, the air outlet 122 is located in the internal space of the building, that is, the air outlet 122 at the end of the central air conditioner can be located in the indoor environment without the aid of a duct. Therefore, the space occupied by the end of the central air conditioner can be further reduced, and the wind loss caused by setting a duct in the prior art can be reduced.

[0035] It can be understood that in the prior art, air is usually introduced into an indoor environment through an air duct. The first end of the air duct is connected to the air outlet 122 of the central air-conditioning terminal, and the second end of the air duct extends into the indoor environment for air outlet.

[0036] According to an embodiment of the present invention, the air-conditioning box body 100 may include a first sub-box body 110 and a second sub-box body 120; the first sub-box body 110 and the second sub-box body 120 enclose to form an inner cavity 150. The first sub-box body 110 is arranged outside the building and located at the top of the building; a first air inlet 111 and a second air inlet 112 are located on the first sub-box body 110; the second sub-box body 120 is arranged in the internal space and located at the top of the internal space, and is connected to the first sub-box body 110. A through hole 121 for installing the lamp 400 is provided on the side of the second sub-box body 120 facing away from the first sub-box body 110. The lamp 400 is located in the through hole 121, and the edge of the lamp 400 is connected to the edge of the through hole 121; an air outlet 122 is located on the second sub-box body 120; a first heat exchanger 200, a second heat exchanger 300 and a condensate receiving component 500 are arranged in the first sub-box body 110; a water receiving cavity is located below the first heat exchanger 200 and the second heat exchanger 300.

[0037] Specifically, during implementation, air in the external space of the building (or can be called the outdoor environment) (see the dotted arrow in Figure 2 ) flows into the second sub-box body 120 through the first sub-box body 110, and then flows out through the air outlet 122 of the second sub-box body 120; the second sub-box body 120 can provide an installation base for the lamp 400 for installation; and, since a part of the air-conditioning box body 100 (the second sub-box body 120) is located in the internal space of the building (or can be called the indoor environment), only the first sub-box body 110 is located in the external space of the building, that is, only the first sub-box body 110 is exposed outside. Therefore, the external space of the building occupied by the central air-conditioning terminal (the air-conditioning box body 100) is small.

[0038] In this embodiment, the first air inlet 111 and the second air inlet 112 are arranged opposite to each other along a first direction D; the first direction D is perpendicular to the height direction of the air-conditioning box body; the second sub-box body 120 is arranged on the side of the first sub-box body 110 facing the internal space and located at the middle position of the first sub-box body 110; there are two air outlets 122, and the two air outlets 122 are respectively a first air outlet and a second air outlet; the first air outlet and the second air outlet are arranged opposite to each other along the first direction D.

[0039] According to an embodiment of the present invention, the terminal of the central air conditioner of the present invention may further include a heat insulation curtain 600, which is located in the second sub-box 120 and connected to the second sub-box 120. The heat insulation curtain 600 is in a retracted state when the central air conditioner terminal is in the cooling mode, so as to cool the lamp 400 through cold air; the heat insulation curtain 600 is in an unfolded state when the central air conditioner terminal is in the heating mode, so as to separate the hot air and the lamp 400.

[0040] Specifically, when the central air conditioner terminal is in the cooling mode, by retracting the heat insulation curtain 600, the cold air located in the second sub-box 120 and after heat exchange can contact the lamp 400 to dissipate heat from the lamp 400. That is, the present invention can not only cool the lamp 400 by water cooling with condensed water, but also cool the lamp 400 by air cooling with the cold air formed in the cooling mode, improving the heat dissipation capacity of the lamp 400; when the central air conditioner terminal is in the heating mode, by unfolding the heat insulation curtain 600 to cover the upper end of the lamp 400, the hot air is separated from the lamp 400, and the hot air will not exchange heat with the lamp 400, will not cause the lamp 400 to heat up, and will not affect the water cooling heat dissipation performance of the lamp 400, ensuring the heat dissipation capacity of the lamp 400 when the central air conditioner terminal is in the heating mode.

[0041] In this embodiment, the heat insulation curtain 600 can be of the prior art. In the unfolded state of the heat insulation curtain 600, the heat insulation curtain 600 can be arranged in the horizontal direction.

[0042] As Figure 3 shown, according to an embodiment of the present invention, the terminal of the central air conditioner of the present invention may further include a first motor 700, a lead screw 800, a lead nut 900, a mounting shaft 1000 and a second motor 1100. The first motor 700 is located in the second sub-box 120 and connected to one side of the second sub-box 120 along the first direction D. The output end of the first motor 700 is connected to the end of the lead screw 800; the lead screw 800 can be arranged horizontally, and the lead nut 900 is sleeved on the lead screw 800; the mounting shaft 1000 is arranged in the horizontal direction and perpendicular to the lead screw 800. One end of the mounting shaft 1000 rotatably passes through the third side of the second sub-box 120; the second motor 1100 is arranged on the fourth side of the second sub-box 120, and the output end of the second motor 1100 is connected to the other end of the mounting shaft 1000; the first motor 700 and the second motor 1100 can rotate synchronously; the third side and the fourth side are oppositely arranged; one end of the heat insulation curtain 600 is connected to the side wall of the mounting shaft 1000 and can be wound around the mounting shaft 1000, and the other end of the heat insulation curtain 600 is connected to the lead nut 900.

[0043] In specific implementation, when the heat insulation curtain 600 is to be deployed, the first motor 700 and the second motor 1100 can be turned on, and the first motor 700 and the second motor 1100 are rotated clockwise. When the second motor 1100 rotates, the heat insulation curtain 600 will be in a wire-releasing state. At the same time, when the first motor 700 rotates, it will drive the lead screw 800 to rotate. When the lead screw 800 rotates, the lead nut 900 will move linearly along the first direction D. The linear movement of the lead nut 900 will pull the heat insulation curtain 600 to move, making the two ends of the heat insulation curtain 600 gradually move away from each other, thereby deploying the heat insulation curtain 600, as Figure 3 shown; when the heat insulation curtain 600 is to be retracted, the first motor 700 and the second motor 1100 can be turned on, and the first motor 700 and the second motor 1100 are rotated counterclockwise. When the second motor 1100 rotates, the heat insulation curtain 600 will be in a wire-winding state. At the same time, when the first motor 700 rotates, it will drive the lead screw 800 to rotate. When the lead screw 800 rotates, the lead nut 900 will move linearly along the first direction D. The linear movement of the lead nut 900 will pull the heat insulation curtain 600 to move, making the two ends of the heat insulation curtain 600 gradually approach each other, thereby retracting the heat insulation curtain 600.

[0044] According to an embodiment of the present invention, the central air-conditioning terminal of the present invention may further include a first control valve and a second control valve; the first control valve is installed at the first air outlet; the second control valve is installed at the second air outlet; the central air-conditioning terminal has a first state, a second state, and a third state; in the first state, the first control valve and the second control valve are opened to discharge air through the first air outlet and the second air outlet; in the second state, the first control valve is opened and the second control valve is closed to discharge air through the first air outlet; in the third state, the first control valve is closed and the second control valve is opened to discharge air through the second air outlet.

[0045] In specific implementation, in the first state, the first air outlet and the second air outlet discharge air simultaneously, which can maximize the air volume, so as to quickly cool or heat; in the second state, only the first air outlet discharges air to achieve unilateral air discharge in the indoor environment; in the third state, only the second air outlet discharges air to achieve unilateral air discharge in the indoor environment.

[0046] According to an embodiment of the present invention, the central air-conditioning terminal of the present invention may further include an air outlet pipe, the air outlet pipe is located in the indoor environment, and the end of the air outlet pipe is connected to the first air outlet.

[0047] According to an embodiment of the present invention, the central air-conditioning terminal of the present invention may further include an existing spherical adjustable air outlet structure, which is provided at the second air outlet.

[0048] According to an embodiment of the present invention, the central air-conditioning terminal of the present invention may further include an EC (Electrical Commutation) fan. The EC fan can be an existing technology. The EC fan is located in the inner cavity 150 and is connected to the cavity wall of the inner cavity 150.

[0049] In specific implementation, the EC fan can adjust its rotational speed, thereby adjusting the air volume, achieving the effect that although the EC fan is closer to the indoor environment, the noise is reduced.

[0050] According to an embodiment of the present invention, the liquid cooling channel further has a channel outlet, and the channel outlet is communicated with the sewer pipe.

[0051] In specific implementation, the condensed water received by the condensed water receiving member 500 will flow through the liquid cooling channel of the lamp 400. Since the temperature of the condensed water is relatively low, after the condensed water flows through the liquid cooling channel of the lamp 400, it will take away the heat of the lamp 400, dissipate heat from the lamp 400, so as to make full use of the condensed water. After the condensed water completes the heat exchange, it will flow to the sewer pipe.

[0052] The present invention also provides a central air conditioner, including a main unit and a central air conditioner terminal, and the central air conditioner terminal is connected to the main unit. The specific structure, working principle and beneficial effects of the central air conditioner terminal are the same as those of the above embodiments, and will not be elaborated here.

[0053] In summary, the characteristics and advantages of the central air conditioner terminal and the central air conditioner of the present invention are as follows:

[0054] 1. Utilize the low temperature characteristic of the condensed water to cool the lamp 400, which can protect the chip of the lamp 400 and extend the service life of the lamp 400.
