A kind of aircondition that has deflector
Technical field
The utility model relates to room conditioning, relates in particular to a kind of aircondition that has deflector.
Background technology
The modal air conditioner in machine room of data center mostly adopts down the air-out mode; Following air-out air-conditioning is on air current composition; Mainly contain two kinds of implementations: (1) adopt evaporimeter last, indoor circulation blower fan under arrangement, as far as the evaporimeter windward side, be the mode of air draught; (2) adopt evaporimeter down, the indoor circulation blower fan is at last arrangement, as far as the evaporimeter windward side, is the mode of blowing.In order to make evaporimeter windward side air current composition comparatively even, between evaporimeter and indoor circulation blower fan, increase a uniform flow orifice or equal drift net.
Above two kinds of technical schemes all deposit following defective: (1) evaporator coil last, indoor circulation blower fan under arrangement, make that air-out unit and last air-out unit all have a great difference on structural design and air current composition down, design compatibility is bad; (2) adopt evaporimeter down, the indoor circulation blower fan is last; And between evaporimeter and indoor circulation blower fan, increase a uniform flow orifice or equal modes of drift net; Can cause the interior windage of unit to increase greatly, improve the air-out static pressure of blower fan, make power of fan increase greatly; And uniform flow orifice or equal drift net processing technology complicacy, cost is higher.
Summary of the invention
The purpose of the utility model is to solve the problem that exists in the above-mentioned prior art, proposes a kind of aircondition that has deflector.
The air-conditioner that has deflector of the utility model design comprises: with the indoor set and the off-premises station of pipeline connection; Said indoor set slave is disposed with indoor return air inlet, indoor circulation blower fan under the direction cashier's office in a shop; Evaporimeter, compressor and indoor air outlet; Wherein: described evaporimeter is obliquely installed in rack, mounting guiding board in the air path system between said indoor circulation blower fan and the evaporimeter.
Described deflector is one to be fixed on the bending plate on indoor set frame side wall top.Said bending plate and indoor set frame side wall form the triangular support face.
Two acute angle scopes that said deflector and indoor set frame side wall form are in 30-60 degree scopes.
Compared with prior art, the utlity model has following advantage:
With adopt uniform flow orifice or all drift net following air-out unit relatively, what deflector was housed goes out Ventilator Room down
Unit, implementation is simpler, and windage is littler in the unit, and power of fan is littler, moves more energy-conservation;
2. the following air-out unit of deflector is housed, and the compatible topology layout of last air-out unit makes that indoor circulation blower fan, evaporimeter, the pipe-line system of upper and lower air-out unit can be just the same, has realized normalization from designing;
3. the following air-out unit of deflector is housed; Optimized the air current composition of evaporimeter windward side; Make that the heat exchange property of heat exchanger is more efficient; The compressor of having avoided occurring because of certain stream cold-producing medium evaporation imperfection of the evaporimeter that the air current composition inequality causes returns liquid, has improved the security of unit operation;
4. deflector is fixed on the machine frame, has strengthened the structural strength of whole unit, has improved transportation intensity.
Description of drawings
Below in conjunction with accompanying drawing and preferred embodiment the utility model is at length explained, wherein:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model is made up of indoor set 1 and off-premises station 2, is connected through pipeline 3 between indoor set and the off-premises station.The indoor set slave is disposed with indoor return air inlet 8, indoor circulation blower fan 7, evaporimeter 5, compressor 4 and indoor air outlet 11 cashier's office in a shop under the direction.
In the time of the compressor refrigeration system operation, the heat that the evaporimeter 5 in the indoor set 1 absorbs in the machine room, and through the condenser in the off-premises station 2 that heat is diffusing in atmospheric environment.
The utility model adopts air-out mode down, and above the indoor circulation blower fan was arranged on, evaporimeter 5 was obliquely installed in rack, with indoor circulation blower fan 7 formation windward sides.Mounting guiding board 6 in the air path system between indoor circulation blower fan 7 and the evaporimeter 5.
In this embodiment, deflector 6 is one to be fixed on the bending plate of indoor set framework upper.This bending plate and indoor set frame side wall form the triangular support face.
In the Crew Cooling System running; Air in the machine room is through indoor return air inlet 8, air-ducting ring and dividing plate 10, indoor circulation blower fan 7; Carry out flowing to evaporimeter 5 after the air current composition optimization through deflector 6 again; Make that evaporimeter windward side air current composition is more even, thereby improve the Crew Cooling System performance greatly.
In the compressor cooling pattern, during the indoor circulation fan operation, the uniformity through the test evaporator face velocity and the temperature of each refrigerant flow path outlet are confirmed the quality of deflector water conservancy diversion effect, and then the optimum arrangement mode of definite deflector and size.Through the unit performance testing authentication, the size of deflector 6 is unsuitable excessive, and it optimizes the best to the unit air current composition with two acute angles of indoor set frame side wall when 30-60 degree scopes.
The utility model is adopting deflector to optimize air current composition in the air-out aircondition down, and simplicity of design makes that the design of upper and lower air-out unit is compatible fully, has significantly reduced the construction cycle; Deflector processing and easy for installation realizes that cost is very low; The evaporimeter face velocity is even; Each stream heat exchange of evaporimeter is even, and each stream temperature difference is compared with the following air-out unit that does not adopt deflector less than 1 degree; Because the effect of deflector makes evaporimeter top exchange capability of heat improve greatly, the unit refrigeration performance obviously improves.
