Cold and heating effect.
Under the refrigeration mode less than -5 DEG C of critical-temperature of refrigeration, room temperature is lower, then the outdoor heat exchanger ratio used is got over
Small, rotation speed of fan is also smaller.Because outdoor temperature is less than refrigeration critical-temperature, it is only necessary to less condenser area, and it is cold
The fan wind speed of condenser is also under minimum speed.When outdoor temperature continues to reduce, it is critical that condensation temperature can be less than refrigeration
Temperature.In order to keep a stable condensing pressure, it is necessary to which heat exchanger area diminishes or with abat-vent according to outdoor temperature
Shield portions heat exchanger either increases air intake resistance., also can be lower by the air quantity of condenser by this measure, than blower fan most
Air quantity under small wind speed is also low.When ambient temperature further reduces, the ventilation of heat exchanger needs further to reduce.And work as
If now outer machine high pressure can not also set up, hot blast of the outdoor unit by condenser discharge can be entered being recycled back to condenser
Wind side, condenser so is circulated through by the way that waste air is constantly interior, can be gradually heated up by condenser, and the height of condenser
Pressure can also be gradually built up, and in the case of reaching outdoor low temperature, the high pressure of outdoor unit can also normally freeze.This measure can be with
Guarantee system is freezed at outdoor -25 DEG C.If the load increase of indoor, outdoor heat exchanger just need big air quantity to go stabilization
Condensing pressure.So, rotation speed of fan can become big, it is necessary to make more air pass through heat exchanger.For varying load condition, Ke Yitong
Cross the stable condensing pressure of change rotation speed of fan.This requires the first fan housing 2 and the second fan housing 3 to be adjusted with the change of outer machine temperature
Heat exchanger incoming air area is saved to adapt to load variations.
For windy air conditioner, just there are multiple snow defences and the first fan housing 2 and the second fan housing 3 of cryogenic refrigeration.First fan housing 2
It is fully wrapped around that heat exchanger exposed into aerial part with the second fan housing 3.
First fan housing 2 and the second fan housing 3 can pass through the spinning movement of multiple wind deflectors 33 of first wind deflector 23 and second
Heat exchanger air-admitting surface and resistance are adjusted, changes the effect of intake volume, while snow shed resistance heavy snow pair can also be used as
The covering of air-conditioning heat exchanger.
Wherein, the first fan housing 2 and the second fan housing 3 have the outdoor temperature sensor of oneself, and its power supply passes through relay
With system four-way valve electric signal UNICOM.
When under cooling system pattern：
(1) as shown in figure 1, working as outdoor temperature T >=-5 DEG C, the second wind deflector 33 is fixed on maximum angle direction clockwise,
The the first sub- standard-sized sheet of air outlet 321 of left end of the second fan housing 3 is kept, the sub- air outlet 322 of right-hand member second is closed.First wind deflector 23 is all protected
Vertical state is held, allows two openings up and down of the first fan housing 2 to keep standard-sized sheet.
(2) as shown in Fig. 2 working as ＜ -5 DEG C of outdoor temperature T, the second wind deflector 33 rotates counterclockwise to maximum angle, keeps
The the second sub- standard-sized sheet of air outlet 322 of right-hand member of second fan housing 3, the sub- air outlet 321 of left end first are closed.Positioned at the top of the first fan housing 2
First wind deflector 23 rotates counterclockwise to maximum angle, second air inlet 21 at the top of the first fan housing of closing 2.Positioned at the first fan housing
First wind deflector 23 of 2 bottoms, being turned clockwise certain angle with the change of outdoor temperature T temperature, outdoor temperature T is lower,
Then the anglec of rotation is bigger, and the aperture of the second air inlet 21 positioned at the bottom of the first fan housing 2 is then smaller.
When system heating four-way valve commutation, action and the refrigeration of the first fan housing 2 and the second fan housing 3 lose middle outdoor
Action during temperature T >=-5 DEG C is identical, ensures heating effect.
When detecting heavy snow signal, the first wind deflector 23 positioned at the top of the first fan housing 2 enters snow defence and acted, and arrives counterclockwise
Maximum angle, close the second air inlet 21 positioned at the top of the first fan housing 2.
When system defrosts, really in cooling mode, the second air inlet 21 of the first fan housing 2 is closed, and first
Sub- air outlet 321 is closed, and heat exchanger and blower fan closing are more conducive to defrost.
The problem of can not freezing when outside air temperature is low instant invention overcomes common air-conditioning in the prior art, the present invention are logical
Cross the combination of structure and control, it is possible to achieve system is freezed at outdoor -25 DEG C.So as to which air-conditioner outdoor unit had both had regulation heat exchange
Device air-admitting surface and resistance, change the effect of intake volume, adapt to different burden requirements, while also there is small windage snow defence
Air intake is designed, and covering of the heavy snow to air-conditioning heat exchanger can be resisted as snow shed.
Air-conditioner outdoor unit according to embodiments of the present invention, include the housing unit of above-mentioned air-conditioner outdoor unit, according to the present invention
The air-conditioner outdoor unit of embodiment, by adjust the second air inlet 21 aperture and the 3rd air outlet 32 and the first air inlet 11 and
Extraneous connected state, the incoming air area and resistance of the first air inlet 11 can be adjusted, and change the effect of intake volume, fitted
Answer different burden requirements, air-conditioning can be made to freeze at low temperature, and can reduce to greatest extent under normal temperature refrigeration and
The influence of heating effect.
Air conditioner according to embodiments of the present invention, including above-mentioned air-conditioner outdoor unit, air conditioner according to embodiments of the present invention,
, can be with by adjusting the aperture and the 3rd air outlet 32 and the first air inlet 11 and the connected state in the external world of the second air inlet 21
The incoming air area and resistance of the first air inlet 11 are adjusted, and changes the effect of intake volume, adapts to different burden requirements, can
So that air-conditioning freezes at low temperature, and the influence to refrigeration and heating effect under normal temperature can be reduced to greatest extent.
