Background technology
In large-scale data processing and storage center machine room, electronic equipment is intensive, can produce amount of heat, usually can set between fixing best effort ambient zone for electronic equipment.Because the machine room nothing whole year is stopped, accurate air conditioner in machine room needs whole year operation, for this reason the annual a large amount of electric power of consumption that needs of air conditioner in machine room.For energy savings, environmental contamination reduction reduces operating cost simultaneously, and increasing client tends to use the accurate air conditioner in machine room of high energy efficiency.
At present, the accurate air conditioner in machine room unit of common upper air-out, normal operation FC blower fan, the return air inlet of FC blower fan is arranged on the positive below of air-conditioning unit, because the air-conditioning unit only has the return air inlet in front, cause by the air quantity of former and later two evaporimeters of air-conditioning unit inconsistent, air quantity by front evaporator is on the high side, and it is on the low side by the air quantity of finisher, and the air-flow by finisher is inhomogeneous, and the heat exchange property of finisher can't normally be brought into play, and causes the refrigerating capacity of air-conditioning unit to descend, Energy Efficiency Ratio is not high, and sensible heat ratio is on the low side.
For this reason, some air conditioner in machine room installs deep bead additional reaching the purpose of mean allocation air-flow at return air inlet or finisher, but the actual poor operability of this method, can't determine the optimum position of deep bead.
The utility model content
The accurate machine room air conditioner that main purpose of the present utility model is to provide a kind of indoor apparatus of air conditioner group and has this indoor apparatus of air conditioner group is intended to improve the Energy Efficiency Ratio of air conditioner in machine room, reduces indoor units consumed power and operating cost.
In order to achieve the above object, the utility model proposes a kind of indoor apparatus of air conditioner group, comprise indoor unit casing, the front of described indoor unit casing is provided with front return air inlet, and the back of described indoor unit casing is provided with the rear return air inlet relative with described front return air inlet.
Preferably, described front return air inlet and rear return air inlet are separately positioned on the lower end of described indoor unit casing.
Preferably, described front return air inlet is provided with front return air screen pack; Described rear return air inlet is provided with rear return air screen pack.
Preferably, described indoor units also comprises: compressor, front evaporator and finisher; Described compressor is installed in the bottom of described indoor unit casing; Described front evaporator and finisher are installed in the top of compressor, and front and back are symmetrically formed V-type.
Preferably, described indoor units also comprises: electric-controlled box, described electric-controlled box is installed in the described indoor unit casing, and is positioned at the front side of described front evaporator and the top of described front return air screen pack.
Preferably, described indoor units also comprises: EC blower fan, described EC assembling and are positioned at the top of described front evaporator and finisher in described indoor unit casing; The air inlet of described EC blower fan vertically downward.
The utility model also proposes a kind of accurate machine room air conditioner, comprises aforesaid indoor apparatus of air conditioner group.
A kind of indoor apparatus of air conditioner group that the utility model proposes and the accurate machine room air conditioner with this indoor apparatus of air conditioner group, because indoor units has adopted front return air inlet and rear return air inlet, by two return air inlets while return air, therefore, the back wind resistance of indoor units front evaporator and finisher is identical, so that identical by the air mass flow of front evaporator and finisher, air-flow is evenly distributed, and has fundamentally solved by front and back evaporator air flow and has not waited gentle stream problem pockety.In addition, said structure also so that the heat exchange property of finisher given full play to, thereby the refrigerating capacity of indoor units is increased, promoted Energy Efficiency Ratio and the sensible heat ratio of indoor units, reduced indoor units consumed power and operating cost.
Description of drawings
Fig. 1 is the structural representation of the utility model indoor apparatus of air conditioner group preferred embodiment.
In order to make the technical solution of the utility model clearer, clear, be described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model indoor apparatus of air conditioner group preferred embodiment.
As shown in Figure 1, a kind of indoor apparatus of air conditioner group that present embodiment proposes, comprise indoor unit casing 8, be arranged on compressor 1, front evaporator 3, finisher 4, electric-controlled box 5 and EC blower fan 2 in the indoor unit casing 8, the front of described indoor unit casing 8 is provided with front return air inlet 60, and the back of described indoor unit casing 8 is provided with the rear return air inlet 70 relative with described front return air inlet 60.
Particularly, described front return air inlet 60 and rear return air inlet 70 are separately positioned on the lower end side position of described indoor unit casing 8, simultaneously, and return air screen pack 6 before described front return air inlet 60 is provided with, return air screen pack 7 after described rear return air inlet 70 is provided with.
In the indoor units of present embodiment, described compressor 1 is installed in the bottom of indoor unit casing 8, and described front evaporator 3 and finisher 4 are installed in the top of compressor 1, and front and back are symmetrically formed a V-shape.
Described electric-controlled box 5 is installed in the described indoor unit casing 8, and is positioned at the front side of described front evaporator 3 and the top of described front return air screen pack 6.
Described EC blower fan 2 is installed in the described indoor unit casing 8, and is positioned at the top of described front evaporator 3 and finisher 4, and the air inlet of this EC blower fan 2 arranges vertically downward.
Present embodiment indoor apparatus of air conditioner group is owing to adopted front return air inlet 60 and rear return air inlet 70, two return air inlet while return air, therefore the back wind resistance of front evaporator 3 and finisher 4 is identical, so that identical by the air mass flow of front evaporator 3 and finisher 4, and the air-flow by front evaporator 3 and finisher 4 is evenly distributed, and has fundamentally solved by front evaporator 3 and finisher 4 air mass flows and has not waited gentle stream problem pockety.
