Description

Technical Field

[0001] The present application relates to the technical field of chilled beams, and in particular to a double-circuit chilled beam. Background Art

[0002] There are different ways to classify chilled beams. According to different installation methods, they can be divided into two types: exposed and embedded. Exposed chilled beams have high thermal efficiency, but are limited by the building. Embedded chilled beams are beautiful, but they will reduce the amount of cooling obtained indoors.

[0003] At present, the patent publication number CN111076280A on the market discloses a chilled beam terminal and a chilled beam system. The chilled beam terminal includes a shell, in which a plurality of injection nozzles are arranged for injecting and mixing indoor return air through the injection airflow flowing out of the shell, and also includes a water receiving member, which is located in the lower area of ​​the injection nozzle to collect condensed water generated by the outer peripheral wall of the injection nozzle.

[0004] With respect to the above-mentioned related technologies, the inventors found that the return air outlets of the chilled beams on the market are at the bottom or on the side walls as in the above-mentioned patents. Therefore, during installation, the user's cabinet or side wall can easily block the return air outlet, resulting in poor return air effect. Therefore, it is necessary to select chilled beams with different return air designs according to the customer's actual installation environment, which leads to the defect of poor applicability. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a double-circuit chilled beam, which has the advantage of being able to adapt to the needs of different installation environments.

[0006] In order to achieve the above object, the technical solution of the utility model is as follows:

[0007] A double-circuit chilled beam comprises a box body, the side walls of the box body are provided with air outlets, and an air supply chamber and a refrigeration element are sequentially arranged in the box body along the direction close to the air outlet; a return air chamber is arranged below the air supply chamber, an L-shaped return air plate is arranged on the return air chamber, and the return air plate comprises a horizontal plate and a vertical plate, and a plurality of return air outlets are arranged on the horizontal plate and the vertical plate.

[0008] By implementing the above technical scheme, the indoor cold air can enter the return air cavity from the return air inlet of the vertical plate (the back side of the box body) and then enter the refrigeration element, or enter the return air cavity from the return air inlet of the horizontal plate (the bottom of the box body) of the return air plate to enter the refrigeration element. That is, at this time, even if the return air inlet of the horizontal plate is blocked due to the installation of the cabinet, the indoor cold air can still enter the return air cavity from the return air inlet of the vertical plate; the cold beam can also be installed as a whole against the wall, relying on the return air inlet of the horizontal plate to enter, thereby improving the overall adaptability of the cold beam.

[0009] As a preferred solution of the present application, the return air plate is detachably connected to the box body.

[0010] Implementing the above technical solution can reduce the occurrence of bending of the return air plate due to the sheet metal during transportation.

[0011] As a preferred solution of the present application, air supply outlets are provided at both ends of the air supply cavity in the length direction.

[0012] The implementation of the above technical solution, that is, the realization of double-sided air inlet, can enable multiple chilled beams to be interconnected, thereby ensuring the air supply effect and improving the convenience of on-site installation.

[0013] As a preferred solution of the present application, a water receiving pan is provided below the refrigeration element, a drain port is provided on the water receiving pan, and the width of the water receiving pan is greater than the width of the refrigeration element.

[0014] By implementing the above technical solution, the water receiving pan is fully enclosed and can fully cover the refrigeration element. Because the L-shaped return air plate shortens the return air area of ​​the horizontal plate, a fully enclosed water receiving pan can be arranged below.

[0015] As a preferred solution of the present application, the air outlet is arranged obliquely below the air supply cavity, and the refrigeration element is arranged obliquely along the air supply cavity to the air outlet.

[0016] By implementing the above technical solution, the inclined refrigeration element can be lengthened in a limited box space, thereby ensuring the heat exchange effect of the refrigeration element, and the wind will blow out from the air outlet at an angle downward, and the cold air will sink, thereby reducing the air outlet resistance.

[0017] As a preferred solution of the present application, the air outlet is detachably provided with an air supply member, the side wall of the air supply member is provided with an air inlet for connecting with the air outlet, and the bottom wall of the air supply member is provided with an air exhaust port.

[0018] To implement the above technical solution, the provision of the air supply element increases the flexibility of the air outlet angle, and the air can be supplied vertically or horizontally, so as to be more flexible to adapt to the ceiling form of the home. For example, if the ceiling is horizontal, the air supply element can be installed to realize vertical downward air supply; if the ceiling is stepped, the air supply element can be omitted to realize horizontal forward air supply.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The indoor cold air can enter the return air cavity from the return air inlet of the vertical plate (back side of the box), and then enter the refrigeration element. It can also enter the return air cavity from the return air inlet of the horizontal plate of the return air plate (bottom of the box) to enter the refrigeration element. That is, at this time, even if the return air inlet of the horizontal plate is blocked due to cabinet installation, the indoor cold air can still enter the return air cavity from the return air inlet of the vertical plate; the cold beam can also be installed as a whole against the wall, relying on the return air inlet of the horizontal plate to enter, thereby improving the overall adaptability of the cold beam.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-4 This application is described in further detail.

A return air chamber 5 is arranged below the air supply chamber 3, and an L-shaped return air plate 6 is arranged on the return air chamber 5. The return air plate 6 includes a horizontal plate 61 and a vertical plate 62. Both the horizontal plate 61 and the vertical plate 62 are provided with a plurality of return air ports 63, so that indoor cold air can enter the return air chamber 5 from the return air ports 63 of the vertical plate 62 (the back side of the box body 1), and then enter the refrigeration element 4, or can enter the return air chamber 5 from the return air ports 63 of the horizontal plate 61 (the bottom of the box body 1) of the return air plate 6 to enter the refrigeration element 4, that is, at this time, even if the return air ports 63 of the horizontal plate 61 are blocked due to cabinet installation, the indoor cold air can still enter the return air chamber 5 from the return air ports 63 of the vertical plate 62; the cold beam as a whole can also be installed in a wall-mounted position, relying on the return air ports 63 of the horizontal plate 61 to enter, thereby improving the overall adaptability of the cold beam.

[0029] Reference Figure 2 and Figure 3 The return air plate 6 is fixed to the box body 1 by screwing, thereby realizing a detachable connection, that is, it is detachably connected to the box body 1 to reduce the occurrence of bending of the return air plate 6 due to the sheet metal during transportation.

[0030] Reference Figure 2 and Figure 3 The air outlet 2 is arranged obliquely below the air supply cavity 3, and the refrigeration element 4 is arranged obliquely along the air supply cavity 3 to the air outlet 2, so that the obliquely arranged refrigeration element 4 can be lengthened in the limited space of the box body 1, thereby ensuring the heat exchange effect of the refrigeration element 4, and the wind flow will be blown out obliquely downward from the air outlet 2, and the cold air flow will sink, thereby reducing the wind outlet resistance.

[0031] Air supply ports 7 are provided at both ends of the air supply cavity 3 in the length direction, so that double-sided air inlet can be achieved, enabling multiple chilled beams to be interconnected, thereby ensuring the air supply effect and improving the convenience of on-site installation.

[0032] A water receiving pan 8 is provided below the refrigeration element 4, and a drain port is provided on the water receiving pan 8. The width of the water receiving pan 8 is greater than the width of the refrigeration element 4, so that the water receiving pan 8 forms a full-cover type and can "fully cover" the refrigeration element 4. Because the L-shaped return air plate 6 shortens the return air area of ​​the horizontal plate 61, a full-cover type water receiving pan 8 can be provided below, and the condensed water in the water receiving pan 8 can be uniformly discharged from the drain port.

[0033] Reference Figure 1 and Figure 4, the air outlet is detachably provided with an air supply member, that is, the air supply member 21 can be directly screwed and fixed on the air outlet, or it can be connected through a pipe to adjust the installation position of the air supply member 21. An air inlet for connecting to the air outlet is provided on the side wall of the air supply member, and an air outlet 22 is provided on the bottom wall of the air supply member. An inclined guide plate 23 is provided between the air inlet and the air outlet so that the wind can be discharged from the air outlet normally. The provision of the air supply member increases the flexibility of the air outlet angle, and the air can be supplied vertically or horizontally, so as to be more flexibly adapted to the ceiling form of the home. For example, if the ceiling is horizontal, you can choose to install an air supply member to realize vertical downward air supply; if the ceiling is stepped, you can choose not to install an air supply member to realize horizontal forward air supply.

[0034] The implementation principle of a double-circuit chilled beam in an embodiment of the present application is as follows: indoor cold air can enter the return air cavity 5 from the return air outlet 63 of the vertical plate 62 (back side of the box body 1), and then enter the refrigeration element 4, or it can enter the return air cavity 5 from the return air outlet 63 of the horizontal plate 61 (bottom of the box body 1) of the return air plate 6 to enter the refrigeration element 4, that is, at this time, even if the return air outlet 63 of the horizontal plate 61 is blocked due to cabinet installation, etc., the indoor cold air can still enter the return air cavity 5 from the return air outlet 63 of the vertical plate 62; the chilled beam as a whole can also be installed against the wall, relying on the return air outlet 63 of the horizontal plate 61 to enter, thereby improving the overall adaptability of the chilled beam.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
