Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and the present invention will be described in detail in conjunction with the embodiments.
The air conditioner of embodiment one includes housing and the upper air outlet being arranged on housing and lower air outlet, wherein, on
Air outlet and lower air outlet are oppositely arranged, air conditioner have make air outlet upper outlet air state, make lower air outlet
Lower outlet air state and make the outlet air state up and down of air outlet and lower air outlet outlet air at the same time.As shown in Figure 1, air conditioner is also
Including the heat exchanger 10 being arranged in housing, under heat exchanger 10 has the upper heat exchanging part 20 for corresponding to upper air outlet and corresponds to
The lower heat exchanging part 30 of air outlet.Wherein, upper heat exchanging part 20 includes upper heat exchanger tube 21, and lower heat exchanging part 30 includes lower heat exchanger tube 31, on
The entrance of heat exchanger tube 21 and the entrance of lower heat exchanger tube 31 are provided with throttling arrangement 40, and throttling arrangement includes being arranged on lower heat exchange
First throttling device 41 on pipe 31 and the second throttling device 42 being arranged on heat exchanger tube 21.
Using the technical solution of the present embodiment one, by setting first throttling device 41 and second throttling device 42, or
The coolant quantity of upper heat exchanging part 20 and lower heat exchanging part 30 is adjusted at the same time according to the heat exchange amount of air conditioner, so that refrigerant can be more
Flow into the region that heat exchange amount is big in heat exchanger 10.The adjustment of above-mentioned refrigerant can cause heat exchanger tube 21 and lower heat exchanger tube 31
Temperature is uniform, and the thermal efficiency improves a lot, while reduces the generation of condensation water.Therefore the technical solution of the present embodiment solves existing
It is unbalanced with the presence of the heat exchanger flow path temperature of air conditioner in technology, the problem of condensation water is more.
Specifically, the control method of the air conditioner of embodiment one is：When air conditioner is in upper outlet air state, upper heat exchanging part
20 heat exchange amount is big.Reduce the aperture of first throttling device 41 at this time, and reduce the flow of the refrigerant of heat exchanger tube 31 under inflow,
The flow increase of the refrigerant of heat exchanger tube 21 in inflow, so that refrigerant is more flowed into the big upper heat exchanging part 20 of heat exchange amount,
Increase by 10 heat exchange efficiency of heat exchanger.The distribution of above-mentioned coolant quantity is so that the temperature of upper heat exchanger tube 21 and lower heat exchanger tube 31 is equal at the same time
It is even, reduce the generation of condensation water.And preferably, when air conditioner is in upper outlet air state, the aperture of second throttling device 42
It is constant.
Similarly, when air conditioner is in lower outlet air state, the heat exchange amount of lower heat exchanging part 30 is big.Reduce the second throttling dress at this time
42 aperture is put, and reduces the flow of the refrigerant of heat exchanger tube 21 in inflow, flows into the flow increase of the refrigerant of lower heat exchanger tube 31,
So that refrigerant is more flowed into the big lower heat exchanging part 30 of heat exchange amount.And preferably, when air conditioner is in lower outlet air shape
During state, the aperture of first throttling device 41 is constant.
When air conditioner is in upper and lower outlet air state, upper heat exchanging part 20 is identical with the heat exchange amount of lower heat exchanging part 30, makes at this time
First throttling device 41 is identical with the aperture of second throttling device 42, and then makes heat exchanging part 20 and lower heat exchanging part 30 in inflow
Coolant quantity it is identical.
It should be noted that being defaulted as outlet air during the air conditioner refrigeration of embodiment one, heating is defaulted as lower outlet air.Specifically
Ground, cold wind density is larger because gravity meeting nature declines, and hot wind density is smaller to be ramped up, and above-mentioned air-out mode can make
Air-conditioner wind not blow-through human body is obtained, and then improves human body comfort.Certainly, in order to increase the intensity of refrigeration or heating, refrigeration and
Heating can use upper and lower outlet air state to run.Upper air outlet and lower air outlet equal outlet air when freezing, upper air outlet during heating
With the lower equal outlet air of air outlet.
As shown in Figure 1, in the technical solution of embodiment one, the area equation of upper heat exchanging part 20 and lower heat exchanging part 30, into
And ensure the heating of air conditioner and the stability of refrigeration.
Preferably, throttling arrangement 40 is solenoid valve or is expansion valve.
As shown in Figure 1, air conditioner further includes refrigerant manifold 50, the first refrigerant branch pipe 60 and the second refrigerant branch pipe 70.Wherein,
The first end of first refrigerant branch pipe 60 and the second refrigerant branch pipe 70 is connected with refrigerant manifold 50, and the second of the first refrigerant branch pipe 60
End is connected with the entrance of upper heat exchanger tube 21, and the second end of the second refrigerant branch pipe 70 is connected with the entrance of lower heat exchanger tube 31.The
One throttling arrangement 41 is arranged on the second refrigerant branch pipe 70, and second throttling device 42 is arranged on the first refrigerant branch pipe 60.
As shown in Fig. 2, difference lies in only in lower heat exchange with embodiment one according to the embodiment two of the air conditioner of the application
The inlet of pipe 31 is provided with throttling arrangement 40.If heat exchanger inner space is limited, it is preferable to the technology of selection example two
Scheme.More serious due to occurring the situation of condensation water during upper outlet air refrigerated medium, throttling arrangement 40 is alternatively provided at lower heat exchanger tube
31 inlet.Specifically, the control method of air conditioner is：When air conditioner is in upper outlet air state, reduce throttling arrangement 40
Aperture.
As feasible embodiment, throttling arrangement 40 can also be set only on upper heat exchanger tube 21, at this time air conditioner
Control method is, when air conditioner is in lower outlet air state, reduces the aperture of throttling arrangement 40.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
