Abstract
The utility model relates to a multi-partition novel blower fan, which is characterized in that a blower is arranged on the upper stream of cooler (heater) along the flow direction; a side circulation way is arranged between a blower and a cooler (heater); the air doors of multi cold (hot) air outlet and multi side circulation air outlet are reversely interlocked to open and close, and form multi blowing branches. In each branch, the air blow after cooling or heating will be mixed with the side circulation air blow in different proportion; consequently, the mixed wind in each branch will be sent to each air condition sub-area with different temperature to satisfy the requirements of load change of different air condition sub-area.
Description
The utility model relates to the new blower fan of the new structure in a kind of HVAC specialty, is applicable to the multi partition air-conditioning and construction.
At present, known new blower fan all belongs to " the new blower fan of induction type ", and it mainly is to be made of fresh wind port, cooling (heating) device, pressure fan and air outlet.Along airflow direction, pressure fan is positioned at the downstream of cooling (heating) device, so the air-supply that can only produce a kind of temperature, humidity parameter at one time, is applicable to the air-conditioning system in single space.Having in the multicell building of some air conditioning zonings (as the Sector East, South Area, Westbound, North Area), because the maximum load of each subregion does not produce at one time, the air quantity air-supply of deciding of only a kind of temperature, humidity parameter is difficult to satisfy simultaneously the requirement of each subregion.When it satisfied the humiture requirement of least favorable subregion, the humiture of other subregion is inevitable to surpass required standard to some extent, thereby causes waste and discomfort.
The purpose of this utility model provides the new blower fan of a kind of multi partition, and it can meet its new wind of the air supply parameter of needs separately for a plurality of air conditioning zonings in the multicell building provide cost-effectively.
The purpose of this utility model is achieved in that its structure is made up of fresh wind port, roughing efficiency air filter, medium effeciency filter, pressure fan, cooling (heating) device, damping device, water fender, tank, cold (heat) wind plenum chamber, bypass wind plenum chamber and cold (heat) wind air outlet and bypass wind air outlet.Wherein, place the upstream of cooling (heating) device, rather than as " the new blower fan of induction type ", place the downstream of cooling (heating) device along the airflow direction pressure fan; The outlet air end of cold (heat) wind plenum chamber connects cold (heat) wind air outlet that a plurality of sectional areas can be inequality; Export at pressure fan and to establish reduction of fractions to a common denominator road on one side between cooling (heating) device, this bypass is led to the bypass plenum chamber along separate routes, and the outlet air end of bypass plenum chamber connects the bypass wind air outlet that a plurality of sectional areas can be inequality; Cold (heat) wind air outlet is identical with the number of bypass wind air outlet, and corresponding one by one; The air door of each cold (heat) wind air outlet all and the reverse interlock of air door of the bypass wind air outlet corresponding with it rise and close, form a plurality of " air doors to ".The air-supply of drawing from two plenum chambers has different temperature, humidity parameter, and the two can produce different air supply parameters as mixing with different air quantity ratios.Therefore, for multicell building with some air conditioning zonings, can draw an air-supply branch road (pipe) for each subregion by a plurality of " air doors to " of the new blower fan of multi partition, and the air supply parameter of each branch road (pipe) to be load variations (being reflected on the indoor temperature) according to this air conditioning zoning regulate to change by the reverse keying interlock of corresponding " air door to " mixes wind and recently adjust, to adapt to the burden requirement of this air conditioning zoning.For example, when certain air conditioning zoning is prescribed a time limit on the indoor temperature in summer rises to above design temperature, the aperture that interlock is regulated is corresponding " air door to ", the air door of cold wind air outlet is opened greatly, the air door of bypass air outlet turns down, thereby reduced this temperature, promptly reduced the wind pushing temperature of this air conditioning zoning air door mixed downstream wind.Be lower than under the design temperature in limited time when the temperature of certain air conditioning zoning drops to, then the keying direction of above-mentioned air door is reverse, thereby improves the wind pushing temperature of this warm area.
The reverse keying interlock mode of above-mentioned " air door to " is coaxial interlock or discrete adjusting interlock.
Above-mentioned air outlet both can place the top of the new blower fan of multi partition to become to go up air-out (as Fig. 2), also can place the sidewall of the new blower fan of multi partition to become horizontal air-out (as Fig. 3).
Owing to adopted such scheme, can under the condition that each air conditioning zoning load constantly changes, the wind pushing temperature of each air conditioning zoning correspondingly be changed by a new blower fan of multi partition, reduced the load in cold (heat) source, reach the purpose of economical rationality.
The outstanding example that the new blower fan of multi partition is used is the air-conditioning and construction that is used for having outskirt and inner region and two-pipe water system.In the winter time, water system is hot-water supply only, but inner region needs cold wind, and the hot blast that general new blower fan is sent is suitable for outskirt, but is not suitable for inner region, thereby causes the imbalance of inner region temperature.Only the new blower fan of multi partition can be simultaneously provides hot blast and provides cold wind (opening the air door of big its bypass air outlet) for inner region for outskirt.
A lot of buildings have the requirement of air wetting in the winter time.The utility model is for satisfying humidification, and available mode has steam humidification, wet-film humidifying, high-pressure spray humidification and other types, is determined by the designer according to field condition.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the top view of new first embodiment of blower fan of multi partition.
Fig. 2 is the profile of new first embodiment of blower fan of multi partition.
Fig. 3 is the profile of second embodiment of the new blower fan of multi partition.
Among the figure 1.Pressure fan 2.Cooling (heating) device 3.Humidifier 4.Cold (heat) wind plenum chamber 5.Bypass plenum chamber 6.Cold (heat) wind air outlet 6` bypass wind air outlet 7.Damper (leafy control valve) 8.Maintenance wicket 9.Tank 10.Dividing plate 11.First effect, middle effect air cleaner 12.Bellows 13.Fresh wind port 14.Damper 15.Water fender
The extrusion end that cooling (heating) device (2) in the new as seen from the figure blower fan and humidifier (3) all are in pressure fan (1).Enter cold (heat) wind plenum chamber (4) behind air-supply air communication supercooling (heating) device and the humidifier.What be in that pressure fan extrudes end together has bypass plenum chamber (5) in addition.Respectively pick out cold (heat) the wind air outlet (6) and the bypass wind air outlet (6`) of equal number from plenum chamber (4) and plenum chamber (5), its each air outlet is all established a damper (7) (leafy control valve).The air door of the air door of cold (heat) wind air outlet (6) and the bypass wind air outlet (6`) corresponding with it opens and closes that direction is opposite, and interlock is regulated, thereby the temperature of mixing wind that changes air-supply branch road (pipe) is with the needs of suitable this correspondence air conditioning zoning.
Other annexes among the figure: wicket (8) is the usefulness that enters new blower fan for the maintainer, tank (9) is for accumulating the condensed water of following of cooler, dividing plate (10) plays interval action between cold (heat) wind plenum chamber (4) and bypass plenum chamber (5), just effect, middle effect air cleaner (11) are to be the impurity such as dust in the filtered air, and bellows (12) is a damping part.
