Abstract
The utility model discloses an installation structure of a non-volute backwards inclined direct connection fan in air-conditioning indoor unit. The installation structure adopts the scheme that the non-volute backwards inclined direct connection fan is mounted at the air outlet; a heat exchanger, which adopts a V-shaped inclined plate structure, is mounted below the non-volute backward inclined direct connection fan; an air return cavity and an air supply cavity of the fan are completely separated by a separating plate therein; and the height of the perpendicular space of a air return port at the lower part of the non-volute backward inclined direct connection fan is half of the diameter of the fan. By adopting the structure, while the wind volume of the unit is remarkably increased, the refrigerating capacity is also considerably improved.
Description
Technical field
The utility model relates to macro-energy special air conditioning for device room indoor units, and particularly unit are refrigerating capacity and air flow rate proportioning require bigger room conditioning unit, specifically are a kind of mounting structures that does not have volute BI direct connection blower fan in this indoor apparatus of air conditioner group.
Background technology
Because the computer room equipment and technology is more and more advanced, its structure is also more and more compacter, but the equipment heating amount in its machine room also is doubled and redoubled, and the unit are thermic load is by 400 original～500w/m
2Rise to 1000 present～1200w/m
2At this variation, air conditioner in machine room also must be closelyed follow trend, accomplish refrigerating capacity big in floor space little, the user can dispose more machinery equipment in effective place like this.
If the air-conditioning unit is accomplished bigger refrigerating capacity, must make the heat exchange area of heat exchanger reach design load, air quantity also must reach GB/T19413-2003 " computer and data processor room unit type air conditioner " design code value.
No volute BI direct connection blower fan is a kind of novel fan that occurred in recent years, is used widely in industries such as HVAC, ventilation, refrigeration.Compare with traditional bel-drivenn centrifugal blower and to have following advantage:
(1) high system effectiveness: high impeller static pressure efficiency
Optimal air inflow and outflow condition
Do not need guiding device
There is not transmission loss
(2) backswept impeller does not transship phenomenon
(3) direct driving motor does not have the wearing and tearing of belt, has avoided secondary pollution
(4) compare with the blower fan of belt drives and reduced bearing load.
To effectively improve the operating efficiency of air-conditioning if it is applied to the special air conditioning for device room indoor units, still, also not have this kind blower fan is applied to the record of special air conditioning for device room indoor units at present in this area.
The utility model content
Technical problem to be solved in the utility model is to adopt a kind of novel mounting means that does not have volute BI direct connection blower fan, makes seamless combination between itself and the air-condition heat exchanger, makes air-conditioning have best performance ratio between unit occupied area and refrigerating capacity.
A kind of mounting structure that does not have volute BI direct connection blower fan in the indoor apparatus of air conditioner group described in the utility model, comprise shell, no volute BI direct connection blower fan and heat exchanger, no volute BI direct connection blower fan and heat exchanger are installed in the enclosure, wherein do not have volute BI direct connection blower fan and be installed in the air outlet place, heat exchanger is installed in no volute BI direct connection blower fan below, described heat exchanger is that the V-type inclination is board-like, and its inside isolates the return air chamber and the wind pushing cavity of blower fan fully with dividing plate.The height of above-mentioned no volute BI direct connection blower fan bottom return air inlet vertical space is 0.5 times of blower fan diameter.
The present invention utilizes common inclination plate type heat exchanger that the type blower fan is installed, have higher requirements for installation dimension,, must reach 0.5 times of blower fan diameter particularly to the size of return air inlet vertical space, if after satisfying the requirement of blower sizes on the structure, and it is too small to leave the effective dimensions of heat exchanger for.Then can cause heat exchange area too small, the bad stability during operation of refrigeration system, the compressor low pressure is lower than 4bar, and heat exchanger surface draws frost to freeze when serious, causes the refrigeration system paralysis not move.
Secondly, the return air sealing of blower fan must be guaranteed, if mainly be that the return air of unit can not all be taken away cold by heat exchanger, then can cause the ducting system short circuit, and cold causes energy waste in air-conditioning unit inner loop.
The utility model is made V-type with heat exchanger, and the return air separate space is made in its heat exchanger inside, with dividing plate the return air chamber and the wind pushing cavity of blower fan is isolated (as shown in Figure 1) fully.Such structure not only can satisfy no volute BI direct connection blower fan to the requirement on the size, and its sealing is strengthened greatly.Use instead after the V-type heat exchanger, its surface wind speed was also even relatively when heat exchange area can significantly be increased, and particularly heat exchanger top area and bottom section wind speed are basic identical, made the actual effective rate of utilization of heat exchanger be not fully exerted like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, no volute BI direct connection blower fan described in the utility model is at the mounting structure of indoor apparatus of air conditioner group, comprise shell 1, no volute BI direct connection blower fan 2 and heat exchanger 3, wherein do not have volute BI direct connection blower fan 2 and be installed in air outlet place in the shell 1, heat exchanger 3 is installed in no volute BI direct connection blower fan 2 belows, heat exchanger 3 is board-like for V-type tilts, and its inner dividing plate 4 of using is isolated the return air chamber 5 and the wind pushing cavity 6 of blower fan fully.The height of no volute BI direct connection blower fan 2 bottom return air inlet vertical spaces must be 0.5 times of blower fan diameter.In addition, heat exchanger has also connected knockout 7, expansion valve 8 and compressor 93 times successively.
The utility model is in after tested contrast, relative prior art, and when air quantity was significantly improved, refrigerating capacity was also significantly improved, and its maximum unit area refrigerating capacity improves about about 30% than other like products, reach 65kw/m2, Reach advanced world standards.
