Description
Technical field
The present invention relates to a kind of wind-proof type air-conditioner outdoor unit, belong to air-conditioning equipment field.
Background technology
Traditional air conditioner for both cooling and heating is in heating operations; if external environment more clammy (winter as the north); then often there will be the phenomenon of air-conditioner outdoor unit frosting; if can not defrost in time; then directly can affect the heat transfer effect of heat exchanger in off-premises station, the final heating efficiency reducing air-conditioning.The manufacturer of tradition air conditioner for both cooling and heating, when designing air-conditioning, contemplates the problem of outdoor unit heat exchanger windward side frosting, and propose the technical scheme of defrost, in air-conditioning, devise defrost function, but in actual use, defrosting effect is also bad.Our company analyzes the air conditioner structure on sale in market according to present circumstances; find following problem: traditional air-conditioner outdoor unit adopts horizontal type structure (namely the length of casing is greater than its height); on the rear board that the air inlet of off-premises station is positioned at casing and side panel, suction opeing is positioned on the front panel of casing; the lateral surface (i.e. windward side) of heat exchanger is directly relative with air inlet; under clammy environment, air-conditioning carries out in heating operations; heat exchanger is easy to frosting; therefore, in normal use procedure, the windward side of heat exchanger can produce a large amount of frostings usually.When starting the defrost function of air-conditioning, although blower fan quits work, wind still can blow to commutator face, takes away amount of heat, and simultaneously because air inlet is relative with heat exchanger, therefore wind also can blow to heat exchanger from air inlet, thus has a strong impact on defrosting effect.Good mode is not also had to solve the problem of traditional air conditioner frosting at present.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of and be applicable to air-conditioning heating under clammy environment and the good wind-proof type air-conditioner outdoor unit of windproof defrosting effect.
Wind-proof type air-conditioner outdoor unit of the present invention, comprise casing, blower fan and carry out the heat exchanger of heat exchange with outdoor air, the bottom of the front panel of casing arranges suction opeing, and the top of its rear board or the top of side panel or top panel arrange passive air inlet; Blower fan and heat exchanger are arranged in chassis cavity, and the position of blower fan is corresponding with suction opeing; Blower fan and suction opeing are positioned at the side of heat exchanger, and passive air inlet is positioned at the opposite side of heat exchanger; Have air channel in casing, the passive air inlet on casing is the import in air channel, and the outlet in air channel is corresponding with the lateral surface of heat exchanger.
In the present invention, the air inlet of off-premises station is passive air inlet (can install shutter in passive air inlet), therefore only under the prerequisite of blower fan work, wind could suck from passive air inlet, and flow to heat exchanger along the direction in air channel, being equivalent to heat exchanger is hidden in casing, is namely effectively protected by casing heat exchanger, thus can play protection effect; After blower fan quits work, extraneous wind can not enter into casing internal or blow to the surface of heat exchanger, is conducive to the defrosting of outdoor unit heat exchanger; And passive air inlet upper, suction opeing under, the cold air of discharging from suction opeing is to air-conditioner outdoor unit flowing underneath, and the air that external heat is relatively high sucks heat exchanger from passive air inlet, constantly carries out heat exchange, is conducive to air-conditioning heating.
In the present invention, the fin that heat exchanger comprises some parallel longitudinal arrangements and the heat exchanger tube be applied in fin.Preferably, on the windward side of heat exchanger, the outward flange of fin is 0 ~ 5mm with the distance being positioned at outermost heat exchanger tube.Fin outward flange in the heat exchanger of traditional air conditioner off-premises station is 6 ~ 9mm with the distance being positioned at outermost heat exchanger tube, under clammy environment, because outside air temperature is low, therefore, the outward flange distance heat exchanger tube of fin is far away, and the more difficult thawing of frost, is namely more not easy defrosting.Therefore the method for the spacing reducing fin outward flange and outermost heat exchanger tube is adopted to improve defrost effect in the present invention.
In traditional air conditioner off-premises station, the spacing of fin of heat exchanger is equidistant; be generally 2.2mm; when under clammy environment, (winter as northern China) heats with air-conditioning; easily frosting on fin; and the easy frosting in the outside of fin, inner side not easily frosting; because spacing of fin is less; in the lasting heating operations of air-conditioning; often there will be fin large area by the phenomenon of frost layer shutoff and not easily defrost; sometimes also can freeze; affect heat exchanger heat exchange, the final heating efficiency reducing air-conditioning.In order to address this problem, the present invention adopts following preferred version: in described heat exchanger, and fin ecto-entad at least arranges two groups; Ecto-entad (namely from the windward side of heat exchanger to its lee face), the spacing of fin of each group fin reduces gradually; The spacing of fin being positioned at outermost one group of fin is 2.4mm ~ 4.0mm, considers other factors such as production cost, and the spacing of fin being positioned at one group of fin of inner side can not be too small, the preferred 1.4mm ~ 2.2mm of the present invention.Like this, on the one hand, the spacing of fin of outermost fin is relatively large, even if frosting, also can not easily by the wide arc gap shutoff between fin, on the other hand, the frosting when flowing through the fin in intermediate layer or internal layer of part outside air, effectively prevent the problem of frosting outside fin completely, make frosting even, be conducive to evenly defrost in time simultaneously.
When traditional air conditioner heats in clammy environment, because the water after defrost can not be discharged in time, water therefore often can be caused to build-up ice and accumulate in the situation of heat exchanger the latter half, equally also can affect heat exchanger heat exchange, the final heating efficiency reducing air-conditioning.Present invention employs for this reason and heat exchanger be divided into the technical scheme that upper and lower many group heat exchange units carry out separately draining, concrete preferred following two schemes:
Scheme one:
Described heat exchanger at least comprises two groups of heat exchange units, from top to bottom each heat exchange unit longitudinal direction or inside oblique arrangement; Separated by space bar between upper and lower two groups of adjacent heat exchange units, space bar tilts from inside to outside obliquely.In this programme, each heat exchange unit can not stagger, and also can partly stagger, and also can stagger completely.In order to prevent the hydropexis after defrost, water fender is set in the inner side of space bar.For the ease of being drawn in time fast by the water after defrost, make draining more thorough, at the arranged outside Diversion Plate of space bar, the angle of inclination of Diversion Plate is not less than the angle of inclination of space bar.Consider safety factor, the end downward bending of Diversion Plate is formed safety guard.Between above-mentioned upper water fender and space bar, between space bar and Diversion Plate and between Diversion Plate and safety guard, can arc transition be adopted, to reduce the resistance to water, be conducive to water and discharge in time.
Scheme two:
Described heat exchanger at least comprises two groups of heat exchange units, from top to bottom each heat exchange unit longitudinal direction or inside oblique arrangement, staggers completely between each group heat exchange unit.In order to the water changed into by frost in defrost process being discharged in time, in the bottom of the heat exchange unit of bottom, water collection sheet is set, water collection sheet tilts from inside to outside obliquely, the water of each heat exchange unit is dropped on water collection sheet at any time, and by discharging in drainpipe or the timely machine outdoor of other drainage arrangements.
Except above-mentioned points, due to the limitation of conventional outdoor unit height, the air inlet of usual air-conditioner outdoor unit and the distance of air outlet very near, easily like this cause short-circuit of air, the very large wind of air of not only discharging from air outlet but also can enter off-premises station by air inlet, make operation of air conditioner unstable, therefore the present invention can also adopt following preferred version, the height of outdoor set cabinet is made to be greater than its length, thus the distance greatly increased between passive air inlet and suction opeing, guarantee that operation of air conditioner is stablized, and there is energy-saving effect.
The beneficial effect that the present invention is compared with prior art had is:
The present invention breaches the design concept of traditional air conditioner off-premises station, is particularly useful for the air-conditioning heating under clammy environment, and heat exchanger is hidden in casing, is namely effectively protected by casing heat exchanger, thus can play protection effect; After blower fan quits work, extraneous wind can not enter into casing internal or blow to the surface of heat exchanger, is conducive to the defrosting of outdoor unit heat exchanger; And passive air inlet upper, suction opeing under, the cold air of discharging from suction opeing is to air-conditioner outdoor unit flowing underneath, and the air that external heat is relatively high sucks heat exchanger from passive air inlet, constantly carries out heat exchange, is conducive to air-conditioning heating.
