In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals or the interaction relationship of two elements.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
First with reference to figure 1 and Fig. 2, the air-supply arrangement 1 according to the air-conditioner 100 of the utility model embodiment is described below.As depicted in figs. 1 and 2, jacket 11 and shell cover 12 is comprised according to the air-supply arrangement 1 of the air-conditioner 100 of the utility model embodiment.
The tubular shell that jacket 11 all opens wide for front-end and back-end, the tubular shell that shell cover 12 all opens wide for front-end and back-end, jacket 11 is set in outside shell cover 12, limit inner chamber between jacket 11 and shell cover 12, this inner chamber can be that the gap between jacket 11 and shell cover 12 limits.
Wherein jacket 11 is connected with the back-end closure of shell cover 12, jacket 11 is provided with the air inlet 111 for being communicated with the inner air channel 21 of air-conditioner 100 and inner chamber, and the front end of jacket 11 and shell cover 12 limits the air outlet 122 for communication with cavity and external environment condition.Wherein, air outlet 122 can be the front opening of above-mentioned inner chamber.
Thus, the air in air-conditioner 100 inside after heat exchanger 22 heat exchange flows to air inlet 111 and enters into inner chamber under the driving of the drive unit (such as driving wind wheel 23) of air-conditioner 100 inside, then blows out through air outlet 122 forward from inner chamber.Wherein from this air outlet 122 blowout wind be through with heat exchanger 22 heat exchange after wind, i.e. cold wind or hot blast.
Jacket 11 and shell cover 12 are tubular shell, and the air outlet 122 that the front end of jacket 11 and the front end of shell cover 12 limit is general toroidal.It should be explained that, due to the tubular shell that shell cover 12 all opens wide for front-end and back-end, therefore after the rear end of shell cover 12 is connected with the back-end closure of jacket 11, the vent passages 121 of this air-supply arrangement 1 through before and after the cavity that the inwall of shell cover 12 limits is formed, and this air outlet 122 is roughly arranged around vent passages 121.
Wherein, be understandable that, " air outlet 122 is general toroidal " described here refers to that air outlet 122 is formed around shell cover 12, and air outlet 122 can be closed ring, also can be non-enclosed construction, and namely air outlet 122 also can be the loop configuration disconnected.
When drying at a high speed forward from air outlet 122, according to Bernoulli effect, the air pressure of the air of contiguous air outlet 122 surrounding reduces, draught head can be formed thus in the front-end and back-end of vent passages 121, therefore vent passages 121 rear end air can under the effect of pressure reduction flow forward, thus can supplemental air flow be formed, after this supplemental air flow mixes with the wind blown out from air outlet 122, continuation is sent forward, to carry out air conditioning to room.
Wherein, the supplemental air flow of supplementing forward from vent passages 121 rear end is the heat exchange of the heat exchanger 22 not through air-conditioner 100 inside, identical with environment temperature, therefore the cold wind blown out from air outlet 122 or after hot blast mixes with supplemental air flow, the temperature difference of cold wind or hot blast and environment temperature can be reduced, the defect that in prior art, air-conditioner 100 leaving air temp is too high or too low can be improved like this.And to a certain extent, the supplemental air flow that vent passages 121 rear end supplements forward can increase the air output of air-conditioner 100, thus can improve the efficiency of air conditioning, and the comfort level of people is improved.
Wherein, be understandable that, supplemental air flow can by rear flow forward in vent passages 121, and certain supplemental air flow can also in the outside of jacket 11 by rear flow forward, and the flow of supplemental air flow can be made thus larger, and air output is more.
To sum up, can improve according to the air-supply arrangement 1 of the air-conditioner 100 of the utility model embodiment the defect that in prior art, air-conditioner 100 leaving air temp is too high or too low, air output is large, and the comfort level of people is improved.
After many experiments, draw, by adopting the air-supply arrangement 1 of the utility model embodiment, following beneficial effect can be had: by arranging the air quantity increment rate >2.0 of the air output after this air-supply arrangement 1 applicant.Vertical air conditioner such as certain model is as follows through actual measurement air output data: be 1190m by the circulating air flow of heat exchanger 22
3/ h is 2512m by the total blast volume of the air-supply of air-supply arrangement 1
3/ h, the air quantity of supplemental air flow is 1322m
3/ h, the air quantity increment rate arranged after this air-supply arrangement 1 is 2.11.Therefore the air quantity by arranging this air-supply arrangement 1 increases Be very effective.
