[0042] According to the implementation of the present utility model, a HVAC device 100 is proposed, please refer to Figure 1-Figure 5 The HVAC equipment 100 includes a shell 20, a temperature sensor 50 and two heat exchangers 40. An upper chamber 21 is formed inside the shell 20, an exhaust port communicating with the upper chamber 21 is formed at the top of the shell 20, and a temperature detection hole 2031 communicating with the upper chamber 21 is formed on the side wall of the shell 20. The two heat exchangers 40 are located in the upper chamber 21, and the two heat exchangers 40 are spaced apart along a first direction X, and the first direction X is perpendicular to the height direction Z of the shell 20. The temperature sensor 50 is located in the upper chamber 21, and the temperature sensor 50 is located between the two heat exchangers 40, and is spaced apart from the heat exchangers 40 along the first direction X.

[0043] The number of the temperature detection holes 2031 on the side wall of the housing 20 may be one or more, and the temperature detection holes 2031 include but are not limited to circular holes, rectangular holes, polygonal holes, and the like.

[0044] It should be pointed out that the HVAC equipment 100 can adjust the indoor cooling or heating through the external ambient temperature obtained by the temperature sensor 50. When the obtained external ambient temperature deviates greatly from the actual ambient temperature, the value adjusted by the HVAC equipment 100 will deviate greatly from the preset value, affecting the cooling or heating effect. In this embodiment, a temperature detection hole 2031 is set on the side wall of the shell 20, and the air outside the shell 20 flows into the upper chamber 21. The temperature sensor 50 detects the temperature of the air entering the upper chamber 21. The temperature sensor 50 is set between the two heat exchangers 40 and is spaced apart from the two heat exchangers 40. This can reduce the influence of the two heat exchangers 40 on the heat radiation or cold radiation of the temperature sensor 50, and at the same time reduce the influence of sunlight radiation on the temperature sensor 50, so as to reduce the temperature detection deviation of the temperature sensor 50.

[0045] In some embodiments of the present invention, please refer to Figure 6 Along the height direction Z of the shell 20, the distance between the bottom of the temperature sensor 50 and the bottom of the heat exchanger 40 is L, and the height of the heat exchanger 40 is H, where L≤1 / 3H.

[0046] When the HVAC equipment 100 dissipates heat, the heat generated by the heat exchanger 40 gradually increases from bottom to top. In order to reduce the heat radiation effect of the heat exchanger 40 on the temperature sensor 50, the temperature sensor 50 is set at a position below 1 / 3H of the heat exchanger 40. This can reduce the deviation of the temperature sensor 50 in detecting the external ambient temperature.

[0047] In some embodiments of the present invention, along the height direction Z of the shell 20 , the distance between the bottom of the temperature sensor 50 and the bottom of the heat exchanger 40 is greater than or equal to the minimum distance between the edge of the temperature detection hole 2031 and the bottom of the heat exchanger 40 .

[0048] Wind from the external environment enters from the temperature detection hole 2031 and is discharged upward from the exhaust port. The wind passes through the temperature sensor 50 so that the temperature sensor 50 can obtain the temperature of the external air to reduce the detection deviation.

[0049] In some embodiments of the present invention, along the first direction X, the minimum distances between the two heat exchangers 40 and the edges of the temperature detection hole 2031 are equal.

[0050] Thus, the temperature detection hole 2031 can be placed away from any heat exchanger 40 to reduce the influence of the heat exchanger 40 on the external air temperature, thereby reducing the detection deviation.

[0051] In some embodiments of the present invention, please refer to Figure 4 , along the first direction X, the minimum distance between the temperature sensor 50 and each heat exchanger 40 is greater than or equal to 20 mm.

[0052] like Figure 4 As shown, along the first direction X, the minimum distance between the temperature sensor 50 and one heat exchanger 40 is Wmin1, and the minimum distance between the temperature sensor 50 and another heat exchanger 40 is Wmin2, Wmin≥20 mm, and Wmin2≥20 mm.

[0053] This can prevent the temperature sensor 50 from being too close to the heat exchanger 40, which would cause the temperature sensor 50 to be greatly affected by the heat radiation or cold radiation of the heat exchanger 40, resulting in a large deviation in the external ambient temperature obtained by the temperature sensor 50.

[0054] In some embodiments of the present invention, along the second direction Y, the temperature sensor 50 forms a projection on the side wall having the temperature detection hole, and the projection at least partially overlaps with the temperature detection hole 2031. The second direction Y is perpendicular to the first direction X and the height direction Z of the heat exchanger 40, that is, the temperature sensor 50 can be roughly opposite to the temperature detection hole 2031 along the spacing direction of the two heat exchangers 40.

[0055] Thus, wind can blow directly from the temperature detection hole 2031 to the temperature sensor 50, so as to improve the accuracy of the ambient temperature detection by the temperature sensor 50. In other examples, the temperature sensor 50 can be offset from the temperature detection hole 2031 by a certain distance along the spacing direction of the two heat exchangers 40.

[0056] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the temperature sensor 50 is spaced apart from the side wall having the temperature detection hole 2031 along the second direction Y.

[0057] Exemplarily, the minimum distance between the temperature sensor 50 and the side wall may be, but is not limited to, any value between 10 mm and 20 mm.

[0058] The side wall is easily affected by sunlight radiation, which increases the temperature of the side plate 203. When the temperature sensor 50 is close to the side plate 203, the ambient temperature detected by the temperature sensor 50 deviates greatly from the actual ambient temperature. Therefore, the detection deviation of the temperature sensor 50 can be reduced by setting the side plate 203 and the temperature sensor 50 at a distance.

[0059] In some embodiments of the present invention, please refer to Figure 5 The HVAC equipment 100 further includes a connecting piece 70 , and the temperature sensor 50 is disposed on the connecting piece 70 . The connecting piece 70 is located in the upper chamber 21 and connected to the shell 20 .

[0060] Optionally, the connecting member 70 may be, but not limited to, a connecting plate, and the connecting plate may be, but not limited to, a bent plate.

[0062] In some embodiments of the present invention, please refer to Figure 5 The shell 20 also includes a mounting frame 60, which is located in the upper chamber and connected to the heat exchanger 40. The mounting frame 60 is spaced apart from the side wall having the temperature detection hole 2031, and the connecting plate is connected to the mounting frame 60.

[0063] The temperature of the side wall changes greatly due to the influence of the external environment temperature. Connecting the connector 70 to the mounting bracket 60 can reduce the heat transfer between the connector 70 and the side wall, so that the temperature sensor 50 can detect the ambient temperature more accurately. In other embodiments, the connector can also be connected to the side wall with the temperature detection hole, so that the temperature sensor 50 is closer to the temperature detection hole 2031.

[0064] In some embodiments of the present invention, the connecting member 70 is a plastic member or a heat insulating member.

[0065] When the connecting member 70 is a heat insulating member, the material of the connecting member 70 may be a heat-insulating material, specifically but not limited to glass fiber, asbestos or rock wool.

[0066] Setting the connector 70 as a plastic part or a heat insulating part can reduce the heat exchange between the connector 70 and the side plate 203, so as to reduce the influence of the side plate 203 on the temperature sensor 50, thereby further improving the accuracy of the temperature sensor 50 in detecting the ambient temperature.

[0067] In some embodiments of the present invention, the housing 20 includes a top cover 202, a support member 204, and two side plates 203.
