Reference numeral in figure is: 1. cabinet; 2. upper end centrifugal blower; 3. upper end air inlet; 4. lower end air outlet; 5. lower end centrifugal blower; 6. upper end wind pipe; 7. lower end intake stack; 8. heat exchanger core body; 9. LCDs.
The specific embodiment
Referring to Fig. 1,2,3, be main body front view and cutaway view and the side view of the eccentric shape centrifugal blower of the utility model intelligent heat exchange system.Comprise:
One cabinet 1, one upper end centrifugal blower 2, one upper end air inlets 3, bring out air port 4 once, and described air inlet 3 and air outlet 4 are loaded on indoor;
One lower end centrifugal blower 5, one upper end wind pipe 6, one lower end intake stacks 7, described upper end wind pipe 6 and lower end intake stack 7 by wall window be connected to outdoor;
And be positioned at the heat exchanger core body 8 that one of middle part connects upper end centrifugal blower 2 and lower end centrifugal blower 5, for isolated indoor air circulation and outdoor air circulation, and allow room air and outdoor air produce sufficient heat exchange;
Described upper end centrifugal blower 2 one sides are connected with upper end air inlet 3, and a side is connected with described heat exchanger core body 8, and after heat exchange, cooled gas is discharged from lower end air outlet 4;
Described lower end centrifugal blower 5 one sides are connected with described heat exchanger core body 8 with lower end intake stack 7 opposite side that is connected, and upper end wind pipe 6 is connected with described heat exchanger core body 8, outdoor cold air enters lower end centrifugal blower 5 from lower end intake stack 7, be dumped into heat exchanger core body 8, after heat exchange, the gas after heating is from upper end wind pipe 6 discharge chambers.
During work, when the base station indoor temperature is higher and indoor and outdoor temperature difference when larger when above (usually be greater than 5 degree), the temperature sensor of intelligent heat exchange system records when indoor/outdoor temperature-difference surpasses setting value enabling signal is passed to PLC, machine is brought into operation, due to the characteristic of air be hotter atmospheric density than low level in upper strata, a colder atmospheric density high position is in lower floor, thereby the hot-air that is positioned at top in the centrifugal blower suction chamber of upper end, the lower end centrifugal blower sucks and is positioned at the outdoor cold air that is positioned at lower, fully carries out heat exchange.
As shown in Figure 2, this top and bottom centrifugal blower 2 and 5 is eccentric shape centrifugal blower, and described heat exchanging core 8 is for tilting to connect.The benefit of design can reduce the volume of heat exchanging core like this, thereby reduces the volume of overall thermal exchange system, and increases heat exchange length and area, makes heat exchange more abundant.

Be positioned at cabinet front middle part with a LCDs 9 for Current Temperatures inside and outside display room and air quantity, also can set pattern manually or automatically.Can set the opening time during automatic mode, and the temperature difference is enabled or stops using when how much spending.
The area of upper end air inlet 3 can be larger than the area of lower end air outlet 4, more being conducive to hot-air discharges, or by air inlet and air outlet is windowed as three faces cashier's office in a shop or window in four sides, (do not paste when dead with wall is installed when the back side, can do and window) is to increase air intake and air draft area.
The pipe shape that inlet and outlet is connected to centrifugal blower need be made smooth surface or dull and stereotyped along connecing form, should avoid the air inlet/outlet area to increase suddenly or the right-angle bending form that reduces etc., to avoid too much wind loss.
Exist in addition, on the pipeline of inlet and outlet, screen pack can be installed, with the airborne particulate matter of filtering, to play the effect of protection machine, can play the effect purified air simultaneously.This screen pack needs regular dedusting or replacing, to guarantee this machine, keeps good operational effect.
As shown from the above technical solution, the utlity model has following beneficial effect:
1. an indoor and outdoor heat-shift, and exchange of air not, stop dust and moisture to invade and harass;
2. only consume 1/10 electric energy of traditional air-conditioning, compressor-free, without chemical refrigerant for equipment provides continuous, stable running environment, guarantees the energy-efficient operation of unit simultaneously;
3.
Reduce the volume of overall thermal exchange system, and increase heat exchange length and area, make heat exchange more abundant.
