Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning equipment, in particular to a jet air conditioning unit. Background Art

[0002] In the field of modern building environment control, jet air conditioning units, as a highly efficient and flexible air conditioning equipment, are widely used in various large public spaces and industrial facilities to achieve precise temperature control, air flow distribution and indoor air quality optimization.

[0003] However, in actual application, especially in environments with specific humidity conditions and large temperature differences, when the cold air flow delivered by the air-conditioning unit passes through the spherical nozzle, the surface temperature of the spherical nozzle is lower than the dew point temperature of the surrounding air, and condensed water droplets are easily formed on the contact surface between the spherical nozzle surface and the hot and humid air of the environment, which is the so-called "condensation" phenomenon. This condensation not only affects the appearance of the nozzle and causes visual discomfort, but may also drip onto the facilities or personnel below, causing safety hazards. More seriously, long-term condensation accumulation may cause nozzle corrosion, affect its airflow delivery performance, and even cause electrical short circuits and other faults, posing a threat to the stable operation of the air-conditioning system. In addition, the spherical nozzle structure has many cold bridges, which aggravates the heat loss of the cold air flow during transmission, reduces the energy efficiency of the air-conditioning system, and increases energy consumption.

[0051] The jet air conditioning unit in this application generally includes the following main components:

[0052] Casing: As the overall structural support of the unit, it is usually made of aluminum alloy or other lightweight, high-strength materials, providing a stable and durable frame.

[0053] Filter: Installed inside the unit, used to initially purify the air entering the air conditioning system, remove impurities such as dust and particulate matter, protect subsequent equipment and ensure the delivery of clean air.

[0054] Surface cooler (or heater): It is the core heat exchange device in the air conditioning system. It cools (or heats) the air by exchanging heat with cold (hot) medium water to adjust the supply air temperature.

[0055] Fan: Provides power to drive the air to circulate inside the unit and delivers the treated air to a distant target area through a spherical nozzle. Fans are usually equipped with a variable frequency control system to achieve precise adjustment of the air volume.

[0056] Spherical nozzle: As a unique design of air outlet, the spherical nozzle can form a directional, high-speed air jet, realizing long-distance, ductless air supply. Spherical nozzles are usually equipped with an adjustable mechanism, allowing the air supply angle and direction to be adjusted to meet different space layouts and airflow distribution requirements.

[0057] like Figure 1-Figure 10 As shown, some embodiments of the present application provide a jet air conditioning unit, including a shell 100 and a spherical nozzle 200 arranged on the shell 100.

[0058] The spherical spout 200 includes a ball bucket 220 and a spherical spout body 210 .

[0059] The ball bucket 220 is used to be fixedly connected to the housing 100 .

[0060] The spherical nozzle body 210 is movably embedded in the ball bucket 220 , and a portion of the spherical nozzle body 210 extends out of the ball bucket 220 .

[0061] The outer protrusion of the spherical nozzle body 210 is spherical, and a spherical internal space is formed inside the ball bucket 220 . The spherical nozzle body 210 is movably embedded in the internal space of the ball bucket 220 .

[0062] The spherical nozzle body 210 is provided with an air passage A. The airflow inside the housing 100 is ejected from the air passage A, and the spherical nozzle can form a directional and high-speed airflow jet.

[0063] See also Figure 4 and Figure 5 The spherical nozzle body 210 is composed of a spherical inner part 211, a first heat insulating part 212, a spherical outer part 213, and a second heat insulating part 214 which are connected end to end to form a shell structure having an inner ring wall and an outer ring wall, and a first closed cavity B is formed between the inner ring wall and the outer ring wall.

[0064] The ball inner member 211 and the ball outer member 213 are both made of metal materials, such as aluminum alloy, iron alloy, etc.

[0065] The ball inner part 211 is disposed on the inner side, and the ball outer part 213 is disposed on the outer side.

[0066] The first heat insulating member 212 is disposed at the outlet end of the air passage A, that is, the first heat insulating member 212 is located at the frontmost air outlet position of the spherical nozzle body 210 .

[0067] The second heat insulating member 214 is disposed on the outer ring wall of the spherical nozzle body 210 .

[0068] The ball inner member 211 has an inner portion located inside and an outer portion bent outward and forward along its rear end, and a wind path A is formed in the middle of the inner portion of the ball inner member 211 .

[0069] The cold air is blown out through the air path channel A, and the cold air directly contacts the ball inner part 211, so that the temperature of the ball inner part 211 is relatively low. However, since the ball inner part 211 does not directly contact the external hot and humid air, no condensation is generated.

[0070] The outer ball part 213 partially extends out of the ball bucket 220 and contacts the external environment. The first thermal insulation part 212 and the second thermal insulation part 214 separate the outer ball part 213 from the inner ball part 211. It is a heat-insulating design without cold bridges. Therefore, the cold air cannot be transferred from the inner ball part 211 to the outer ball part 213, and the outer ball part 213 is not in direct contact with the cold air. Therefore, the temperature of the outer ball part 213 is not low. Although it is in contact with the external hot and humid air, it does not produce condensation.

[0071] Since the spherical nozzle body 210 can rotate in the ball bucket 220, when the spherical nozzle body 210 rotates to the maximum angle, as shown in FIG. Figure 6 and Figure 7As shown, the second heat insulating member 214 does not extend out of the ball bucket 220, which can ensure that the ball inner member 211 is completely located in the ball bucket 220 and does not come into contact with the external hot and humid air, thereby avoiding condensation. At the same time, the second heat insulating member 214 does not extend out of the ball bucket 220, thereby improving the appearance of the spherical nozzle 200.

[0072] The first thermal insulation member 212 and the second thermal insulation member 214 may be made of plastic, such as ABS plastic.

[0073] The first heat insulating member 212 and the second heat insulating member 214 may be bonded and fixed to the ball inner member 211 and the ball outer member 213 by adhesive.

[0074] The cross-sectional shape of the first heat insulating member 212 is substantially U-shaped, and the inner side thereof is connected to the front end of the spherical inner member 211 , and the outer side thereof is connected to the front end of the spherical outer member 213 .

[0075] In order to facilitate bonding and fixing, overlapping steps are respectively provided on both side end surfaces of the first thermal insulation member 212 for overlapping with the front end edges of the spherical inner member 211 and the spherical outer member 213 .

[0076] The cross-sectional shape of the second heat insulating member 214 is arc-shaped, constituting a part of the spherical arc surface of the outer wall of the spherical nozzle body 210 .

[0077] Similarly, in order to facilitate bonding and fixing, the end faces of both sides of the second thermal insulation member 214 are also provided with overlapping steps for overlapping with the rear end edges of the ball inner member 211 and the ball outer member 213 .

[0078] In other embodiments of the present application, the second thermal insulation member 214 can be arranged at the inlet end of the air path A, that is, it is arranged opposite to the first thermal insulation member 212. The cross-sectional shape of the second thermal insulation member 214 is roughly U-shaped, and its inner side is connected to the rear end of the ball inner member 211, and the outer side is connected to the rear end of the ball outer member 213.

[0079] In the above-mentioned jet air-conditioning unit, the spherical nozzle body 210 in the spherical nozzle 200 uses an insulating component assembly method to cut off the cold bridge, so that the spherical outer part 213 exposed to the external environment has no cold transfer, which solves the serious condensation problem that is easy to occur on the surface of the spherical nozzle 200 due to the characteristics of the metal material, and significantly improves the stability of the operation of the air-conditioning unit.

[0080] In some embodiments of the present application, Figure 4 and Figure 8 As shown, the ball bucket 220 includes a ball bucket front 221 , a ball bucket rear 222 and a first ball bucket heat insulation member 223 .

[0081] The ball bucket rear 222 is located at the rear side of the ball bucket front 221 , and both are made of metal material, and can be made of the same material as the ball inner part 211 and the ball outer part 213 .

[0082] The first ball bucket heat insulation member 223 is located between the front ball bucket 221 and the rear ball bucket 222 , and is fixedly connected to the front ball bucket 221 and the rear ball bucket 222 .

[0083] The front ball bucket 221 , the first ball bucket heat insulation 223 and the rear ball bucket 222 are connected in sequence, and a spherical internal space D is formed inside. The spherical nozzle body 210 is movably embedded in the internal space D of the ball bucket 220 .

[0084] When air is supplied, the rear part 222 of the ball bucket is in direct contact with cold air and has a relatively low temperature. The first ball bucket heat insulation part 223 is used to insulate the air, thereby ensuring that the cold air will not be transferred to the front part 221 of the ball bucket, and the temperature of the front part 221 of the ball bucket will not decrease, so that condensation will not be generated.

[0085] The first bucket heat insulation member 223 may be made of plastic, such as ABS plastic.

[0086] The first ball bucket heat insulation member 223 may be bonded and fixed to the ball bucket front 221 and the ball bucket rear 222 by an adhesive.

[0087] In order to facilitate bonding and fixing, overlapping steps are respectively provided on both side end surfaces of the first ball bucket heat insulation member 223 for overlapping with the edges of the front 221 and the rear 222 of the ball bucket.

[0088] In some embodiments of the present application, the ball bucket 220 further includes a ball bucket exterior 224 .

[0089] The ball bucket outer portion 224 is disposed on the outer sides of the ball bucket front portion 221 and the ball bucket rear portion 222 .

[0090] The front end of the ball bucket outer 224 is fixedly connected to the ball bucket front 221 ; the rear end of the ball bucket outer 224 is fixedly connected to the ball bucket rear 222 .

[0091] A second closed cavity C is formed between the front 221 of the ball bucket, the rear 222 of the ball bucket and the outer 224 of the ball bucket. The second closed cavity C prevents the side walls of the front 221 of the ball bucket and the rear 222 of the ball bucket from directly contacting the outer 224 of the ball bucket, thereby playing a role of heat insulation.

[0092] See also Fig. 9 In some embodiments of the present application, the front end of the ball bucket front 221 has a ball bucket front flange 2211 bent outward, and the ball bucket front flange 2211 is fixedly connected to the front end of the ball bucket outer 224.

[0093] See also Fig.10 The rear end of the ball bucket rear 222 has a ball bucket rear flange 2221 bent outward.

[0094] The rear end of the ball bucket outer 224 has a ball bucket outer flange 2241 bent inwardly, and the ball bucket outer flange 2241 is fixedly connected to the ball bucket rear flange 2221 .

[0095] The outer flange 2241 of the ball bucket and the rear flange 2221 of the ball bucket can be fixedly connected by adhesive, fasteners, welding, etc.

[0096] The outer flange 2241 of the ball bucket and the rear flange 2221 of the ball bucket can be bonded and fixed by a foam double-sided adhesive 226, and the foam double-sided adhesive 226 also has a certain heat insulation effect.

[0097] In some embodiments of the present application, a second ball bucket heat insulator 225 is disposed between the front flange 2211 of the ball bucket and the front end of the ball bucket outer 224 , and the second ball bucket heat insulator 225 is fixedly connected to the front flange 2211 of the ball bucket and the ball bucket outer 224 .

[0098] The second ball bucket heat insulation component 225 serves to connect and assemble the ball bucket outer 224 and the ball bucket front 221 , and can also block the transfer of cold energy from the ball bucket outer 224 to the ball bucket front 221 , further improving the overall anti-condensation performance of the spherical nozzle 200 .

[0099] See also Fig. 9 One end of the second ball bucket heat insulation piece 225 has a slot portion, and the other end has a plug-in portion 2251.

[0100] The slot portion is plugged into and matched with the front end barrel edge of the ball barrel outer 224 .

[0101] The front flange 2211 of the ball bucket has a bending step 2212, and a bending groove is provided on the outer side of the bending step 2212 corresponding to the plug-in portion 2251. The second ball bucket heat insulating member 225 abuts against the outer side of the bending step 2212, and the plug-in portion 2251 is plugged into and matched with the bending groove.

[0102] The second bucket heat insulation member 225 may be made of plastic, such as ABS plastic.

[0103] The second ball bucket heat insulation member 225 can be bonded and fixed to the ball bucket exterior 224 and the ball bucket front 221 by adhesive.

[0104] In some embodiments of the present application, the first closed cavity B of the spherical nozzle body 210 is filled with a heat-insulating material (not shown).

[0105] The spherical nozzle body 210 is filled with heat-insulating material, which not only increases the overall structural strength of the spherical nozzle 200 , but also further improves the heat insulation performance of the spherical nozzle 200 , and further improves the overall anti-condensation performance of the spherical nozzle 200 .

[0106] In some embodiments of the present application, the second closed cavity C of the ball bucket 220 is filled with a heat-insulating material (not shown).

[0107] The ball bucket 220 is filled with heat-insulating material, which not only increases the overall structural strength of the ball bucket 220 , but also further improves the heat insulation performance of the ball bucket 220 , and further improves the overall anti-condensation performance of the spherical nozzle 200 .

[0108] The thermal insulation material may be foam, polyurethane foam, polystyrene foam or other foaming materials.

[0109] In some embodiments of the present application, the spherical spout 200 further includes a decorative piece 230, which is an annular piece and is disposed on the front side of the front flange 2211 of the ball bucket. The decorative piece 230 is disposed on the front side of the ball bucket 220 to improve the overall aesthetics of the spherical spout 200. The decorative piece 230 can be a plastic piece or a metal piece. Since the temperature of the front 221 of the ball bucket is not low, condensation will not be generated on the decorative piece 230.
