The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Air-conditioning unit and noise elimination dc fan in the energy-conservation operating room wind treatment system of the present invention are arranged in the double wall of operating room, have so just formed no pipe-line system, make designs simplification, and it is little to take up room, easy for installation, and energy-conservation.Unlike existing wind treatment system need more than 2 floors the space just can, and pipeline is complicated, waste energy and cost too high.Blower fan among the present invention is selected the noise elimination dc fan, and adopts more than 2, and is so not only energy-conservation but also reduce noise, makes that other blower fan can also normally move when a typhoon machine was out of order.The present invention has cancelled many equipment on the basis of existing clean operating room, make the whole construction work simplification, and construction work shortens, and installs simple and convenient.
With reference to shown in Figure 1, a kind of energy-conservation operating room wind treatment system comprises, air-conditioning unit and noise elimination dc fan unit.
Air-conditioning unit and noise elimination dc fan unit are arranged in the double wall 3 of operating room, and said air-conditioning unit is made up of the constant temperature and humidity formula air-conditioning of directly splashing, i.e. first air-conditioning 11 and second air-conditioning 12.
Noise elimination dc fan unit is made up of noise elimination dc fan 2.
Be provided with aseptic isolation body of wall 31 in the double wall 3 of operating room.
Wind treatment system in the present embodiment adopts two-way to advance the mode of new wind, and wherein new wind is self-priming entering system.The wind treatment system adopts the secondary return air technology, reduces the eddy current dead angle area, makes clean-up effect better.
The first via: first air-conditioning 11 sucks new wind in the double wall 3; 400 cubic meters/hours, before new wind gets into double wall 3, contain removable junior middle school through first earlier and imitate the fence mouth 4 of filter, getting into the circulatory system after filtering; After new wind passes through first air-conditioning 11; Getting in the operating rooms through 4 noise elimination dc fans 2, contain the fence mouth 5 of imitating filter in removable junior middle school through second again and get in the double walls 3, so is primary retirn air; Be provided with the 3rd on the top of operating room and contain removable junior middle school and imitate the fence mouth of filter 6, carry out secondary return air, reduce the dead angle in stream swirl district, just clean-up effect is better.
The second the tunnel, the circulation through second air-conditioning 12 is identical with the first via.
The wind of above-mentioned two-way is finally discharged through exhaust outlet 7.
For highly aseptic (cleanliness factor) zone, supply air temperature difference is little because air output is very big, and strengthening return air, reducing heat loss again is effective energy-saving means.Condition is suitable should to adopt secondary return air system as far as possible, but concrete condition need be made a concrete analysis of (seeing table 1) when using.Sterilized space is different from industrial clean rooms, and indoor comparatively speaking wet amount is big, caloric value is less, and secondary return air makes apparatus dew point descend, and often reaches 7 ℃ like the supply water temperature of hospital's chilled water system in summer, often makes each chamber humidity superelevation.For the large-scale diagnostic equipment chamber that needs the high accuracy Temperature and Humidity Control, depend merely on the secondary return air valve regulation and be difficult to the control room internal state.Normal first and second return air that adopts fixed proportion is aided with reheater and finely tunes, and control is stable, and effect is also good.
The comparison of table 1 primary retirn air and secondary return air mode
Referring to Fig. 3, Fig. 4, shown in Figure 5; Said noise elimination dc fan 2 comprises housing 21; In said housing 21, be disposed with blower fan 211, silencer 212, pocket type medium effeciency filter G4 213, high efficiency particulate air filter H4 217 and diffusing discharge orifice plate 214 from top to bottom, wherein, said blower fan 211 is fixed in the top of said housing 21 through blower fan half suspension holdfast 215; Said silencer 212 is fixed on the below of said blower fan 2 through silencer half suspension holdfast 216; Said silencer half suspension holdfast 216 is provided with first cushion pad 218 with housing 21 contact positions, and to reduce resonance and noise, said diffusing discharge orifice plate 214 is arranged at the bottom of said housing 21.Said blower fan 21 hangs on the top of said housing 21 through magnetic levitation system 8; Said magnetic levitation system 8 comprises first permanent magnet 81 that is arranged on said blower fan half suspension holdfast 216; And be arranged on the said housing 21 and said first permanent magnet, 81 corresponding second permanent magnets 82; Said first permanent magnet 41 is identical with second permanent magnet, 42 corresponding magnetic poles, to produce the magnetic force of mutual repulsion.
The another kind of scheme that blower fan half suspension holdfast 216 is fixed; Be that blower fan half suspension holdfast 216 is fixedly connected with housing 21 through the pin nail; The place that the pin nail contacts with housing 21 tilts 45 °, can reduce the contact area of pin nail and housing 21 so as far as possible, further reduces resonance; Be provided with second cushion pad 219 at said blower fan half suspension holdfast 216 with housing 21 contact positions, to reduce resonance and noise.
Wind treatment system of the present invention uses at least 2 noise elimination dc fans 2 as power; Present embodiment selects 4 noise elimination dc fans 2 as power.When a typhoon machine other blower fan that is out of order can also normally move, make operating room can also guarantee that operation normally carries out.Blower fan adopts the dc fan of band high-medium efficient filter; The motor operate power is reduced relatively; The air-line system of whole system is simplified, and the air-supply overbottom pressure of blower fan reduces principle, makes the operate power of blower fan carry out the secondary reduction; In 30 square meter rice operating rooms, fan noise can be reduced to below the 48FB at last like this.Guarantee the quiet environment of operating room, met the national regulation requirement.And the 8000m that always blows
3/ h concentrates on the blower fan of blowing on the furred ceiling, and generally so the high-power blower running noises generally can be at 70FB.
