Description
Technical field
The utility model relates to a kind of aircondition.
Background technology
Modernization high-rise building substantially all adopts steel construction to add the form of glass curtain wall, as the Shanghai Center Building of PVG, Jin Mao Tower, Global Finance center.General glass curtain wall have employed and combined by two-way mirror and simple glass, and interlayer is filled with the double glazing of dry air or inert gas.Double glazing have two-layer and three layers point, two-layer double glazing adds seal frame by layer glass, forms a mezzanine space; Triplex glass is then form two mezzanine spaces by triplex glass.Double glazing has the advantages such as sound insulation, heat insulation, antifrost, protection against the tide, wind pressure resistant strength be large.According to measurement, when outdoor temperature is-10 DEG C, the temperature before layer glass window is-2 DEG C, and uses the indoor temperature of three layers of double glazing to be 10 DEG C.And at hot summer, double layer glass can block the solar radiant heat of 90%.Sunlight still can through glass curtain wall, but shines and scarcely can feel hot with it.Use the room of hollow glass curtain wall can accomplish cool in summer and warm in winter, significantly improve living environment.
Current air-conditioning system winter indoor temperature at 21 ~ 22 DEG C, at this temperature, if indoor relative humidity is in 50%, dew-point temperature is at 10.2 ~ 11.1 DEG C, and glass curtain wall just likely produces water smoke.Curtain wall produces the aesthetics that water smoke not only have impact on skyscraper, and affects the light transmittance etc. of working environment.
The demist of current employing glass curtain wall is mainly tandem fin or radiator coil tube.This demister pattern, often because its series connection stroke is very large, reaches more than 100m sometimes, and cause water system resistance very large, energy consumption is high; On the other hand due to the equipment of radiator coil tube not with hot-air compulsory circulation, heat radiation area is less, often needs very high laying density just can reach desirable effect.
The fan coil of our routine has certain air conveying function, can increase the heat radiation area of coil pipe, but its thickness is left back at 250mm, and its physical dimension is mainly limited to the size of blower fan and the efficiency of coil heat exchange.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, the ultrathin low noise efficient demist fan coil units that efficiency is high, noise is low.
Technical solution of the present utility model is:
A kind of ultrathin low noise efficient demist fan coil units, comprise housing, on in housing, return air inlet is set, it is characterized in that: the cross flow fan that DC brushless motor drives is set after return air inlet, broken line type heat exchanger is set above cross flow fan, arrange one-way type air outlet above heat exchanger, arrange condensate drain pan below heat exchanger, condensate drain pan is connected with the condensate pipe of hull outside with dress.
Housing is arranged detachable decoration panel.
Housing outer diameter is 110mm, and unit width is 150mm.
The utility model is rational in infrastructure, and has following advantages:
1, unit blower fan adopts narrow cartridge type cross flow fan, and cylindrical shell outside dimension is 110mm, fan passage size 130mm, and unit width can be controlled in 150mm, comparable conventional rack thin 40%.
2, fan blade adopts percolation blade, and air channel is eddy flow pattern, and efficiency is high, noise is low, can reduce noise 5 decibels.
3, heat exchanger adopts broken line type structure, and arrange the disturbance improving heat transfer area and air-flow, augmentation of heat transfer by the oblique broken line of coil pipe fin, heat transfer area can increase by 25%, and efficiency improves about 20%.
4, adopt DC brushless motor, efficiency is higher, noise is lower, can according to outdoor operating mode stepless time adjustment, and operation energy consumption is low;
5, air-intaking box is can resonant silencing chamber, and the Middle and low frequency noise for blower fan carries out resonant silencing, reduces the sense of discomfort that low-frequency noise causes human body;
6, unidirectional air outlet can adjust wind direction according to air output, is normally off when unit is not blown, and dust can be avoided to fall into unit inside;
7, heat exchange coil can be lower resistance design, can reduce water system resistance in series connection uses;
8, decoration panel is detachable type, is convenient to unit maintenance; Simultaneously can according to decoration demand adjust structure and color, aesthetics is excellent.
