Description
Technical field
The present invention relates to a kind of air-conditioner tail end equipment capable, especially relate to a kind of pipe curtain formula radiation furred ceiling air-conditioner tail end equipment capable.
Background technology
Along with the progressively improvement of living standards of the people, and the developing rapidly of modern building technology, people also improve constantly attractive in appearance and requirement correlation function equipment of building interior trim.
Along with the aesthstic transition of building decoration, the pattern of indoor furred ceiling is also changing thereupon, and attractive in appearance with practical requirement is also improved constantly.Occurred like lacing film formula, square tube or flexible formula smallpox furred ceiling at some large-scale public places such as airport, railway station, subway station, supermarket or market etc. in recent years; Its characteristics are succinctly and not dull and stereotyped, make overall space seem more penetrating open, have directionality; Third dimension is strong; Arris fillet is clear bright and clear, and human body no longer produces narrow sense or sense of depression because of distance, and is attractive in appearance novel unique.But when the terminal layout of air-conditioning system, there are some problems or contradiction.As, to traditional air-conditioning system, send back to the air port must concealed installation above this type of furred ceiling, the one, influence the diffusing stream effect in air port, the 2nd, because this type of furred ceiling light weight, the simple and easy snapping mode of general employing is blown off easily during installation, can send the sound simultaneously; The 3rd,, this type of furred ceiling has been installed, can't adopt the board-like furred ceiling air conditioning terminal of radiation system, especially to large space, sacrificed preferable air conditioning terminal mode, can't reach attractive in appearance with practical doulbe-sides' victory.
At present, to the end equipment of central air conditioner system, more requirement has been proposed also.For example, should reduce air conditioner end equipment taking to the building practical space as far as possible; Should reduce the operation noise of air conditioning terminal etc., so that more comfortable indoor life, working environment to be provided as far as possible; The arrangement form of air conditioning terminal should be flexible as much as possible or the like.Existing radiant type central air conditioner system end equipment can satisfy these requirements preferably: taking of space height asked less; Movement-less part during operation can not produce noise, can not cause the blowing feeling of human body; And the indoor temperature field distribution is more even, and arrangement is flexible and changeable.For the bigger space of span, this type end equipment advantage is more obvious.
But also there are problems in existing radiant type central air conditioner system end equipment.Like the board-like end equipment of common radiation; Contact also heat conduction by tubing (copper pipe or other) and sheet material (aluminium sheet or other) are linear, cold and hot medium is by the tubing transmission & distribution, then by sheet material with cold or heat to external radiation; It is excessive to contact thermal resistance between tubing and sheet material, and the backward radiation heat loss is bigger.Its modified is in tubing and space, sheet material contact wire both sides, to fill other Heat Conduction Materials to increase the heat transfer area between tubing and the sheet material with this, and a card pair heat preserving and insulating material reduces heat loss overleaf simultaneously.But still have following two problems: 1, the storeroom heat conduction efficiency is low, and cold and hot amount need be delivered on the sheet material from tube material and tube wall and filling Heat Conduction Material, has increased the transmission medium and has just inevitably increased heat loss, and overall thermal efficient is still lower; When 2, freezing, the dewfall phenomenon appears in radiating surface easily, and the field distribution of plate surface temperature is uneven; Temperature is minimum on tubing and sheet material contact wire; Dewfall very easily occurs, the requirement radiant panel water inlet water temperature of having to is higher than indoor dew-point temperature, like this; Reduce the temperature difference between supply water temperature and the indoor design temperature, thereby reduced the amount of radiation of radiant panel unit are; 3, radiant panel is produced by factory's modularization, and directly install in the building site, and specific dimensions is arranged, and this helps guaranteeing its performance, but also causes some spaces, corner or irregular space to install, and need take modes such as customization.
Summary of the invention
The technical problem that the present invention will solve is; Overcome some problems that exist when existing lacing film formula, square tube formula or flexible formula furred ceiling and air-conditioning system are terminal arranges; And the above-mentioned defective of existing radiant type central air conditioner system end equipment existence, provide a kind of thermal efficiency high, the anti-condensation ability is strong; On-the-spot simple installation, and the guaranteed pipe curtain of cold and hot radiance formula radiation furred ceiling air-conditioner tail end equipment capable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pipe curtain formula radiation furred ceiling air-conditioner tail end equipment capable, and it comprises at least two tubulose section bars, separate through lower floor's partition and upper strata partition the inner space of tubulose section bar direct-axis bearing of trend; Cavity between lower floor's partition and the tubulose section bar bottom was a water chamber, and the cavity between lower floor's partition and the upper strata partition is the insulation air space, and the cavity between upper strata partition and the tubulose section bar top is open draw-in groove; Be positioned on lower floor's partition of end, tubulose section bar two ends and have connecting hole; On the partition of upper strata, have the vertical resigning hole of direction, connector screws with being connected flexible pipe after from bottom to top passing connecting hole, and fastening through locking nut; Closure plug and tubulose section bar are affixed; Said connection flexible pipe comprises and connects the flexible pipe I and be connected the flexible pipe II that the connector that connects on flexible pipe I end and the feed pipe spins, and the connector that connects on flexible pipe II and the return pipe spins; Tubulose section bar, closure plug, connector, connection flexible pipe, feed pipe, return pipe connect and compose closed hot and cold water runner; Buckle on linking up with the middle part and opening draw-in groove is connected, and hook top is provided with the height adjustment hole, is respectively equipped with locating hole and hole for hoist on the keel both wings; Hook top is connected through height adjustment hole and locating hole and keel, and suspension rod is connected through hole for hoist and keel.
Further, said feed pipe and return pipe can be positioned at the same end of tubulose section bar.When feed pipe and return pipe are positioned at the same end of tubulose section bar, connect through connecting the flexible pipe III between each tubulose section bar other end end.
Further, said feed pipe and return pipe also can lay respectively at tubulose section bar right ends.
Further, said closure plug is affixed through welding or hot melt and tubulose section bar.
Further, said tubulose section bar is plastic-steel section bar or aluminium section bar.
Further, said tubulose section bar cross-sectional profiles can be circle, ellipse or polygon (as: square, rectangle, triangle etc.).
Further, the length of pipe section of said tubulose section bar can be confirmed by design drawing or job site specific requirement or demand.
Further, arrangement pitch can be through being confirmed by the locating hole spacing that is positioned on the keel by design drawing or job site specific requirement between said tubulose section bar.
