The quantity of blower 7 is consistent with the quantity of heat exchanger 6, and the underface that axial flow blower 7 is located at heat exchanger 6 is correspondingly arranged, as machine group leader
For 3.8m, total air-conditioning amount is 5m3When/s, use 1 power of motor for 5.5 kilowatts of blower；The a length of 3.8m of unit, it is total empty
Tune air output is 10m3When/s, use 1 power of motor for 11 kilowatts of blower；The a length of 6.3m of unit, total air-conditioning amount are
15m3When/s, use 2 powers of motor for 7.5 kilowatts of blower；The a length of 6.3m of unit, total air-conditioning amount are 20m3When/s, adopt
The blower for being 11 kilowatts with 2 powers of motor.The blower of different number different capacity is used in the present invention to reach different and send
Wind requires, and blower arrangement corresponding with heat exchanger in the present invention, blower can uniformly blow out the thermal current that heat exchanger generates, and is
Working region provides uniform and stable air-supply air-flow, and uses the set-up mode of three Fans in the prior art, air-supply region weight
It is folded, cause thermal current uneven, so that the heat that causes to blow to working region is uneven, and unit interior air-flow is unstable will lead to
Noise increases to a certain extent.In alternative dispensing means of the present invention, two 6 lower parts of heat exchanger be respectively set four power≤
The blower of 1.5kW, totally eight.Be arranged in the present invention more small-sized fans can make air-conditioner set meet total pressure, it is air-cooled and
Under the requirement of noise reduction, reach the air-supply more uniform stabilization of air-flow, exchange heat the more uniform sufficient effect of degree.
In a kind of preferred embodiment, axial flow blower 7, leaf are set in the middle part of the cavity of wall type Fresh air handing unit lower box 2
Piece inclination angle is about 15 °.Compared with prior art, the axial flow blower of use makes full use of unit to the axial flow blower used in the present invention
The space of inner horizontal, blower fan volume is larger, under the premise of meeting identical air quantity requirement, can use the lesser blower in inclination angle
Blade, while lesser blade tilt can reduce the generation of noise, and the power of required axial flow blower is smaller, effectively improves
Unit efficiency.
In a kind of preferred embodiment, the size of wall type Fresh air handing unit is length >=6m, height >=8m, wide≤1.2m, length and width
Than >=5, depth-width ratio >=6.33 belong to ultra-thin unit, and silencer 8 makes full use of space in ultra-thin unit, using galvanized steel plain sheet
Shell, zinc-plated porous plate and mineral wool are as quieter material.Make full use of unit space that silencer is set in the present invention, use is porous
Quieter material can make noise be reduced to 80dB (A) hereinafter, effectively dropping while reducing units' installation space from 105dB (A)
Low noise is conducive to human health.
In a kind of preferred embodiment, 6 internal coil of wall type Fresh air handing unit heat exchanger and fin use full copper material.
Copper heating tube plasticity is high, and welding process requirement is low, and heating conduction is good, can effectively improve heat exchange in unit and imitate
Rate.In alternative dispensing means, 6 internal coil of set heat exchange device is combined using copper pipe and aluminium foil fin, and aluminium foil is hydrophilic aluminium
Foil, aluminium flake is with a thickness of 0.5mm or more, spacing of fin 4-4.5mm.Condensed water can dissipate rapidly on hydrophilic aluminium foil in the present invention
It opens without condensing into droplet, increases heat exchange area, can effectively avoid noise of the condensed water because hindering air flowing generation, and
And under the operating condition of not water flowing, the hydrophilic film on aluminium foil can effectively reduce indoor alkalescent gas and contact with aluminium flake and to aluminium flake
It causes to corrode, has the effect of anticorrosion, mould proof, through testing, under same environmental conditions, the fin for not covering hydrophilic film is only capable of
Using 12 months, cover hydrophilic film 0.1mm aluminum fin-stock can use about 36 months, and cover hydrophilic film 0.5mm aluminum fin-stock use when
Between can reach 60 months or more.
In a kind of preferred embodiment, 3 top of wall type Fresh air handing unit air compartment be located at right above air compartment 3 be arranged it is horizontal fixed
Blow slot 10, blow slot 10 after volume damper is set, pass through air quantity adjustment sheet continuous transformation angle adjust air quantity, control stream
Speed.The part air quantity of total blast volume 9% is guided into air-supply slot using adjustable plate, and air-supply slot level sends out high speed winds, and wind speed is approximately less than
Orifice plate air-supply region and upper space is isolated in 7m/s, is conducive to carry out machine into working region with blowing high efficiency air flow scattered
Heat treatment.In alternative dispensing means, heretofore described air-supply slot uses adjustable apparatus, makes to blow by continuous rotation
Angle changes (horizontal direction is 0 °) within the scope of -75 °~75 °.When winter send hot wind, thermal current actively rises, by angle of blowing
Degree is lowered；When summer send cold wind, wind direction is raised.Air-supply air-flow group is advantageously implemented by adjusting air-supply slot wind direction
It knits uniform and stable.
In a kind of preferred embodiment, 3 front setting orifice plate air outlet 9 of wall type Fresh air handing unit air compartment, punching rate is
15%, it is about 3.4m/s that orifice plate, which goes out wind velocity,.The present invention use orifice feeding, wind speed is smaller, air-supply uniformly, space temperature variation compared with
It is small, Room air distribution design can be stablized, be conducive to office work regional gas stream and uniformly and stably machine is handled.It is another
In optinal plan, 3 front setting ball-shape air outlet of wall type Fresh air handing unit air compartment.It can using ball-shape air outlet in the present invention
Meet the needs of larger air output in large area workshop, it can be to carrying out specially treated at hot localised points.In alternative dispensing means,
3 front setting orifice plate air outlet 9 of wall type Fresh air handing unit air compartment and ball-shape air outlet.In the present invention using orifice plate air outlet with
