The inside of off-premises station body 1 utilizes demarcation strip 3 to be divided into two parts.The front face side ora terminalis of this demarcation strip 3, consistent with the involutory edge of above-mentioned the 1st front panel 1b and the 2nd front panel 1c.The back side portion of demarcation strip 3, near bending obliquely ora terminalis, the back side ora terminalis of this ora terminalis and above-mentioned bending plate 1d and the involutory edge of checker 1a end are consistent.The last ora terminalis of demarcation strip 3 and top board 1e butt, the following ora terminalis of demarcation strip and base plate 1f butt will be separated in the off-premises station body 1.
On the sidepiece of the front of off-premises station body 1, fan guard 2a, 2b are installed side by side up and down.This fan guard 2a, 2b and the pressure fan described later that is configured in the off-premises station body 1 relatively are installed with, with the degree prevention finger of ventilation and the entering of foreign material that does not influence heat exchange air.
One side of the compartment relative with said fans protective plate 2a installation position that will be in off-premises station body 1 is called heat-exchanging chamber 4, and not relative with fan guard 2a the opposing party's space is called Machine Room 5.
Above-mentioned heat-exchanging chamber 4, from position and the external communications that a part is surrounded by checker 1a, the plate body with the 2nd front panel 1c and bending plate 1d etc. around the Machine Room 5 surrounds, and becomes roughly airtight state.
On above-mentioned the 1st front panel 1b, respectively will around carry out opening up and down side by side, and said fans protective plate 2a, 2b be installed with covering these blow-off outlets with the bellmouth 6a of circle, blow-off outlet 7a, the 7b of circle that 6b surrounds.
Again,, compare, be designed to the bellmouth 6b of lower side and the diameter of blow-off outlet 7b less with the bellmouth 6a of upper side and the diameter of blow-off outlet 7a by reason described later.
In above-mentioned heat-exchanging chamber 4, dispose outdoor heat converter 8, and dispose pressure fan supporting mass 9.On this pressure fan supporting mass 9, above-below direction mounting support side by side the 1st pressure fan 10a and the 2nd pressure fan 10b.
Above-mentioned outdoor heat converter 8 is positioned on the base plate 1f, and its height dimension is designed to the 1st front panel 1b roughly the same.And,, see that from overlooking formation is roughly the L font along the left surface that forms body 1 and the above-mentioned checker 1a at the back side.
Above-mentioned pressure fan supporting mass 9, bottom are fixed on the base plate 1f, and the upper end is only hung in the upper surface of outdoor heat converter 8, makes the lengthwise shape.Be bearing in the 1st, the 2nd pressure fan 10a, 10b on this pressure fan supporting mass 9, aerofoil fan 12a, the 12b that is fixed on the rotating shaft of this fan motor by fan motor 11a, 11b and setting-in constitutes respectively.
Under the state after the assembling, the 1st, the 2nd pressure fan 10a, 10b is positioned at the position relative with blow-off outlet 7a, 7b.The part of above-mentioned aerofoil fan 12a, 12b is inserted in bellmouth 6a, the 6b that is installed among blow-off outlet 7a, the 7b, forms the rotation air-supply in this bellmouth.
Here, its 1 characteristic is: the diameter phi Da of the aerofoil fan 12a among the 1st pressure fan 10a is configured to the diameter phi Db big (φ Da>φ Db) than the aerofoil fan 12b among the 2nd pressure fan 10b.
That is to say, the diameter phi Da of the aerofoil fan 12a of the 1st pressure fan 10a, be set as maximum to greatest extent by spatial condition etc., and the diameter phi Db of the aerofoil fan 12b of the 2nd pressure fan 10b is, as the 1st pressure fan 10a with all guarantee to be suppressed under the minimal prerequisite, set minimum diameter for for the air output of above-mentioned outdoor heat converter 8 and with the reduction of cooling effectiveness.
Certainly, with respect to the output of the fan motor 11a of the 1st pressure fan 10a, be chosen to the output of the fan motor 11b of the 2nd pressure fan 10b less.
Same, be installed in upper side in the mounting center position of not changing upper and lower part side pressure fan, with the 1st pressure fan 10a and the 2nd pressure fan 10b be installed in the occasion of lower side, amount according to than the difference of the radius of the aerofoil fan 12b of the 2nd pressure fan 10b of prior art miniaturization enlarges base plate 1f and the interval of holding in aerofoil fan 12b week.
Perhaps, do not change the installation site of the 1st pressure fan 10a of upper side, the aerofoil fan 12a week end of the 1st pressure fan 10a is made necessarily with the interval of holding in the aerofoil fan 12b week of the 2nd pressure fan 10b, as long as, just can further enlarge the interval of aerofoil fan 12b week end with the base plate 1f of the 2nd pressure fan 10b so the installation site of the 2nd pressure fan 10b is moved to upper side.
In any occasion, all be that aerofoil fan 12b diameter phi Db according to the 2nd pressure fan 10b sets than the little amount of aerofoil fan 12a diameter phi Da of the 1st pressure fan 10a, enlarge the interval of aerofoil fan 12b week end with the base plate 1f of the 2nd pressure fan 10b.
On the other hand, in Machine Room 5, dispose compressor 13, and dispose air accumulator 14 side by side with this compressor 13.The position has cross valve 15 above above-mentioned compressor 13, and compressor 13 is connected by not shown refrigerant pipe with cross valve 15 with air accumulator 14.Again, compressor 13 also is connected by not shown refrigerant pipe with above-mentioned outdoor heat converter 8, constitutes the indoor heat converter and the kind of refrigeration cycle of indoor set.
5 the top in the Machine Room is equipped with electric element box 16.This electric element box 16 is by the front case member 16a that the few electrical equipment class of heat dissipation capacities such as converter and terminal class is installed with control is installed constitutes with the side case member 16b of big electrical equipment class such as the heat dissipation capacity of electrical equipment and high power transistor etc.
Above-mentioned side case member 16b is installed on the formed heat-absorbent surface of one side side of electrical equipment with cooler (being also referred to as radiator) 20 that is equipped on above-mentioned demarcation strip 3 tops.Be formed with radiating surface at electrical equipment with the another side side of cooler 20, it exposes to heat-exchanging chamber 4 sides by demarcation strip 3.
As mentioned above, because electric element box 16 is configured in the top of Machine Room 5, so electrical equipment is installed in the top of demarcation strip 3 with cooler 20, from the extremely near position of the 1st pressure fan 10a on the top that is configured in heat-exchanging chamber 4.
Again, though not shown here, outer conductance hand-hole is located at the rear side top of above-mentioned bending plate 1d, and the conducting that Machine Room 5 is communicated with heat-exchanging chamber 4 is located near the position of the electrical equipment usefulness cooler 20 of demarcation strip 3 with the hole.
As the off-premises station of the air conditioner of such formation, when making the instruction of kind of refrigeration cycle running beginning, compressor 13 is driven, and the 1st, the 2nd pressure fan 10a, 10b driven.
Outer gas sucks to off-premises station body 1 in by checker 1a, circulates in outdoor heat converter 8 and plays heat exchange action.And, be directed to bellmouth 6a, 6b, blow out to the outside from blow-off outlet 7a, 7b.
When making warm running, must frost be attached on the outdoor heat converter 8, so the warm defrosting running of turning round and defrosting of interim suitably interruption system.Along with this defrosting running, the sluicing after dissolving is dripped and is accumulated on the base plate 1f from outdoor heat converter 8.
Especially, because low at the outer temperature degree of cold district, the sluicing that accumulates on the base plate 1f was often build-up ice before discharging.When defrosting running repeatedly, the ice after the sluicing on the base plate 1f is freezed is constantly grown up, and it highly little by little increases.
; in this off-premises station; the diameter phi Db of aerofoil fan 12b among the 2nd pressure fan 10b of lower side is set for littler than the diameter phi Da of the aerofoil fan 12a among the 1st pressure fan 10a of upper side, so can fully guarantee the interval of aerofoil fan 12b week end and base plate 1f.
Therefore, even dissolve the such occasion of degree to ice not making that the temperature rises, the ice of forming that sluices can not grow to the aerofoil fan 12b week end that reaches lower side pressure fan 10b basically.
Therefore, the constraint that aerofoil fan 12b can not be iced is in rotatable state all the time, the overcurrent that in fan motor 11b, can not flow or because of aerofoil fan 12b with ice contact cause the distortion or the breakage, can guarantee reliability.
As previously mentioned, all make less with diameter and can not to obtain the situation of required air output different with the aerofoil fan of 2 pressure fans, owing to can guarantee the air output of the 1st pressure fan 10a as wide as possible, required minimally is guaranteed the air output of the 2nd pressure fan 10b, so be unlikely to cause the such state of affairs of reduction of the heat exchanger effectiveness of outdoor heat converter 8.
And because the electric output of the fan motor 11b of the 2nd pressure fan 10b is littler than the electric output of the fan motor 11a of the 1st pressure fan 10a, the electric output of pretending to total amount has the tendency of minimizing, and can obtain the reduction of operating cost.
Again, because conductance hand-hole outside on above-mentioned bending plate 1d, being provided with, the electrical equipment of demarcation strip 3 with cooler 20 near the position be provided with conducting and use the hole, so air-supply effect along with each pressure fan 10a, 10b, outer gas imports in Machine Room 5 from outer conductance hand-hole, and imports to heat-exchanging chamber 4 with the hole by conducting.
In above-mentioned Machine Room 5, along with the running of compressor 13 drives and has heat release, the electrical equipment of the high power transistor from electric element box 16 etc. to produce heating greatly.
The outer gas that the conductance hand-hole is directed in the Machine Room 5 outside above-mentioned is discharged to heat-exchanging chamber 4 with the hole by conducting with the hot gas of emitting in the Machine Room, therefore, can carry out the cooling in the Machine Room 5.
On the other hand, above-mentioned electrical equipment is with cooler 20, absorbed heat by the heat-absorbent surface of the Machine Room 5 sides big electrical equipment of caloric value from high power transistor etc., dispels the heat from the radiating surface of heat-exchanging chamber 4 sides, and electrical equipment is cooled off.
Since this electrical equipment with cooler 20 near the position be provided with conducting and use the hole, so, just electrical equipment is being cooled off with cooler 20 during from conducting usefulness hole to heat-exchanging chamber 4 importings to the outer gas of Machine Room 5 importings.
Again, electrical equipment exposes to heat-exchanging chamber 4 sides by demarcation strip 3 with the radiating surface of cooler 20, and is in the i.e. extremely near position of the 1st pressure fan 10a of upper side.That is to say that electrical equipment increases with near the wind speed of the aerofoil fan 12a of the 1st pressure fan 10a of cooler 20 relatively, can improve radiating efficiency.
Utilizability on the industry
Adopt the present invention, can obtain to suppress as far as possible the reduction of air output, the wind of minimizing lower side pressure fan Fan the off-premises station that quilt ice retrains the air conditioner of the radiating efficiency reduction that also can stop electrical equipment to use cooler.
