Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Shown in Figure 3, according to embodiments of the invention, provide a kind of air-cooled ducted air conditioner, comprise air inlet 11, air outlet 12 and fan part 13, air-cooled ducted air conditioner is also provided with First Heat Exchanger 21 and the second heat exchanger 22, First Heat Exchanger 21 is arranged between air inlet 11 and fan part 13, and the second heat exchanger 22 is arranged between air outlet 12 and fan part 13.
Air-cooled ducted air conditioner adopts heat exchange mode simultaneously, and first air draught through First Heat Exchanger, then blows air onto on the second heat exchanger through fan blade, like this after twice heat exchange, finally by air outlet, is all carrying out heat exchange while air draught blowing.The direction of arrow in Fig. 3 is the flow direction of air, and air is entered by air inlet and first through First Heat Exchanger, then through fan part break-in, then blows to the second heat exchanger, blow out finally by air outlet.This air-cooled ducted air conditioner is made up of two heat exchangers, and is positioned in the middle of two parts heat exchanger by fan part.Air-cooled ducted air conditioner compared to existing technology, have employed brand-new flow field layout, owing to have employed two groups of heat exchangers, adds heat exchanger area, through twice heat exchange, improves exchange capability of heat, thus improve the heat exchange efficiency of air-cooled ducted air conditioner.
It should be noted that, in the present embodiment, increase heat exchanger respectively in the both sides of fan part, this structure is not only increase heat exchange efficiency by heat exchanger quantity, and also has following beyond thought technique effect:
1) under identical exchange capability of heat, can reduce the length of single heat exchanger, thus reduce the length of air-cooled ducted air conditioner complete machine, also can reduce heat exchanger width, what air-cooled ducted air conditioner air-conditioning was done is thinner.Reduce the volume of air-cooled ducted air conditioner like this, more convenient to install.
2) wind is after twice heat exchange, and the wind of air-cooled ducted air conditioner blowout is softer.
3) because fan part is positioned at the centre of two heat exchangers, the noise that fan part produces can absorb between two heat exchangers, makes noise also can reduce like this.
First Heat Exchanger 21 in the present embodiment and the quantity of the second heat exchanger 22 are one, in the unshowned embodiment of one, the quantity of First Heat Exchanger 21 and the second heat exchanger can be multiple, and the quantity of First Heat Exchanger 21 is at least two, and the quantity of the second heat exchanger 22 is at least two.
In order to control separately two heat exchangers, air-cooled ducted air conditioner also comprises controller, and controller is electrically connected with First Heat Exchanger 21, and controller is electrically connected with the second heat exchanger 22.Under the prerequisite that can ensure heat exchange power, can according to actual needs, consumption saved by closedown First Heat Exchanger 21 or the second heat exchanger 22.
See Fig. 3, air-cooled ducted air conditioner has air channel 14, and air channel 14 is that air-cooled ducted air conditioner housing is formed, and the first end in air channel 14 forms air inlet 11, and second end in air channel 14 forms air outlet 12.
First Heat Exchanger 21 and the second heat exchanger 22 are all positioned at air channel 14, and the bearing of trend of First Heat Exchanger 21 and the second heat exchanger 22 is parallel to each other.First Heat Exchanger 21 and the second heat exchanger 22 all extend along air channel 14 radial direction, and two heat exchanger bearing of trends are axial vertical with air channel 14.
First Heat Exchanger 21 is greater than the distance of First Heat Exchanger 21 and air inlet 11 with the distance of fan part 13.That is; First Heat Exchanger 21 from air inlet more close to; space between First Heat Exchanger 21 with fan part 13 is larger; this structure; make wind enter rear direct and First Heat Exchanger 11 contact heat-exchanging from air inlet 11, the time then entered in air channel 14 is longer, and the air intake heat be conducive to like this entering air channel is protected; reduce the temperature of extraneous air and the exchange of Inside Air Temperature, improve heat exchange efficiency.
Second heat exchanger 22 and the distance of air outlet 12 are greater than the distance of the second heat exchanger 22 and fan part 13.That is the second heat exchanger 22 from fan part 13 more close to, such fan part 13 wind out directly can carry out heat exchange at the second heat exchanger, because the second heat exchanger distance air outlet 12 is comparatively far away, decreases the heat exchange of inner air and extraneous air, improve the heat exchange efficiency of air-cooled ducted air conditioner.
In order to prevent the globule of the generation of heat exchanger in heat transfer process from flowing in air channel, so be provided with drip tray 23 in the bottom of First Heat Exchanger 21 and the second heat exchanger 22, in the present embodiment, two heat exchangers can be evaporimeter or condenser.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
