Description

Technical Field

[0001] The present application relates to the technical field of central air-conditioning systems, and in particular to a fan coil unit connection soft connection structure. Background Art

[0002] The fan coil unit is referred to as a fan coil. It is one of the terminal devices of the air conditioning system, which consists of a small fan, a motor and a coil (air heat exchanger). When chilled water or hot water flows through the coil tube, it exchanges heat with the air outside the tube, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. It is a commonly used cooling and heating terminal device.

[0003] At present, horizontal installation units are mostly hidden on the ceiling, and there are two air supply methods: upper side supply and ceiling downward air supply. If the side supply method is adopted, a low static pressure fan coil unit can be selected, and the unit outlet is directly connected to the double-layer louver air outlet; if the ceiling is used for downward air supply, a high static pressure fan coil unit should be selected, and the unit air outlet is directly connected to the air outlet, and several diffusers are connected on it to supply air downward.

[0004] However, for fan coil units that supply air, when the fan coil units are directly connected to the air outlets, the air outlets are fixed to the fan coil units by means of rivets or screws. This traditional installation method mainly has the following problems:

[0005] 1) The installation speed is slow and the labor cost is high;

[0006] 2) When the fan coil unit is installed on the ceiling, there is no space on the top of the fan coil unit where the air outlet is connected to the air outlet, so the electric drill cannot be used to fix it, which may cause vibration and noise in the later stage;

[0007] 3) Cleaning the heat exchange fins of the fan coil requires removing the screws, which is troublesome and inconvenient.

[0008] Therefore, exploring an efficient, fast and quality-assured connection method can better meet market demand. Utility Model Content

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0037] The fan coil unit used in the present application is a prior art structure, and the fan coil unit has an air inlet and an air outlet connected to the air outlet.

[0038] Embodiment 1:

[0039] like Figure 1 As shown, the present application provides a fan coil unit connection soft connection structure, which includes a soft connection 4 and a rotating handle 2. The soft connection 4 is a machine soft connection. The soft connection 4 includes a hose and a thin steel plate. The thin steel plate is circle-shaped. The two ends of the hose are engaged with the thin steel plate by a machine to form a sealing structure. One end of the soft connection 4 is connected to the air outlet duct, and the other end of the soft connection 4 is sleeved on the air inlet and outlet of the fan coil unit and contacts therewith. The rotating handle 2 is installed in this thin steel plate. The rotating handle 2 cannot move and can only rotate at a certain angle.

[0040] During actual use, the rotating handle 2 does not extend out of the outside of the flexible connection 4, so that the thin steel plate on the flexible connection 4 is sleeved on the end of the air inlet and outlet of the fan coil unit and contacts the outside of the air inlet and outlet of the fan coil unit. By rotating the rotating handle 2 in the flexible connection 4, the upper end of the rotating handle 2 is screwed into the inner side of the steel plate around the air supply outlet of the fan coil unit.

[0048] In order to avoid damage to the fixing plate 1 , the fixing plate 1 is made of a galvanized steel plate.

[0049] In a possible embodiment, the fixing plate 1 is fixed to the flexible connection 4 by means of rivets 3 .

[0050] In a possible embodiment, the end of the thin steel plate connected to the fan coil unit by the flexible connection 4 is provided with an outer flange. A pad made of a sealing strip is installed at the air inlet and outlet ends of the fan coil unit to contact with the flange structure of the thin steel plate, thereby ensuring the sealing of the connection and preventing air leakage.

[0051] In addition, the thin steel plate at the other end of the flexible connection 4 can be made into a flange to connect the air outlet duct.

[0052] In a possible embodiment, the soft connection 4 is made of polyurethane-coated glass fiber cloth or other soft connection materials, such as aluminum foil cloth.

[0053] The use of this application is:

[0054] First, measure the size of the air inlet and outlet of the fan coil unit, and select the appropriate soft connector 4 according to the size of the air inlet and outlet of the fan coil unit;

[0055] Next, fix the fixing plate 1 to a suitable position inside the thin steel plate on the flexible connection by means of rivets 3;

[0056] Finally, the flexible connection 4 is put on the fan coil unit, and the rotating handle 2 inside the flexible connection 4 is turned. The flexible connection 4 is put on the outside of the air inlet and outlet of the fan coil unit and clamped on the fan coil unit to achieve rapid installation of the flexible connection 4 and the fan coil unit.

[0057] Similarly, the flexible connection 4 and the fan coil unit can be quickly disassembled.

[0058] In summary, under the premise of ensuring the connection quality, the connection structure of the present application greatly improves the connection speed between the fan coil unit and the upper end of the soft connection 4, reduces the interference of other types of work during the rush construction stage, and is convenient for practical use.

[0059] Embodiment 2:

[0060] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that, in this embodiment, a flange structure is provided at the end of the thin steel plate connected to the fan coil unit by the flexible connection 4. The flange structure increases the contact area with the sealing strip, effectively avoids damage to the sealing strip, ensures the sealing of the connection, and prevents air leakage.
