Description only actually at least one exemplary embodiment be it is illustrative, never as to the present invention and its application or make
Any restrictions.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Fig. 1 shows the schematic illustration of the air conditioner indoor unit of the present embodiment.As shown in Figure 1, the air conditioning chamber of the present embodiment
Interior machine includes evaporator 1, the throttle part being connected to evaporator 13 and the heat exchanging part 2 being connected to throttle part 3.
When air conditioner is in cooling condition, condensed refrigerant is within the condenser followed by heat exchanging part 2, throttle part
3 and evaporator 1.Optionally, throttle part 3 is electric expansion valve.
When air conditioner is in cooling condition, the refrigerant after compressor compresses enters the condensation in air-conditioner outdoor unit
It is condensed in device, condensed refrigerant is conveyed to air conditioner indoor unit.Condensed refrigerant is when flowing through heat exchanging part 2 and evaporator
1 heat exchange, refrigerant further cool down in heat exchanging part 2.Refrigerant after cooling down in heat exchanging part 2 is after the throttling of throttle part 3
Into in evaporator 1, refrigerant evaporation endothermic in evaporator 1.
Since refrigerant cools down in heat exchanging part 2 before flowing through throttle part 3, the refrigeration of throttle part 3 is flowed to
Gaseous refrigerant in agent is reduced or is disappeared, and the refrigerant for improving gas-liquid two-phase existing in the prior art flows through throttle part
Lead to the problem of loud noise.
Air conditioner indoor unit further includes shell and the air outlet that is arranged in shell.Evaporator 1 and heat exchanging part 2 are arranged at
In shell.Wherein, heat exchanging part 2 is arranged at air outlet.
Air conditioner indoor unit further includes being located at the intracorporal blower of shell, and blower is for driving air to flow through evaporator 1 and heat exchanging part
2, so that evaporator 1 and heat exchanging part 2 sufficiently exchange heat.Blower is also used to that the air to exchange heat with evaporator 1 is discharged through air outlet, passes through
Air after exchanging heat with evaporator 1 exchanges heat during flowing to air outlet with heat exchanging part 2, to flow through the refrigerant of heat exchanging part 2
Cooling.It can be seen that heat exchanging part 2 and evaporator 1 are exchanged heat by the air as medium in the present embodiment.
In order to further decrease the content of the gaseous refrigerant in the refrigerant for flowing to throttle part 3, air conditioner indoor unit is also
Plenum 4 including the pressure for increasing refrigerant, plenum 4 are located at heat exchanging part 2 and throttling along the flow direction of refrigerant
Between component 3.
The elevation of boiling point of pressurized refrigerant, the content of gaseous refrigerant reduces in refrigerant, to reduce refrigeration
The mass dryness fraction of agent, and then the content of the gaseous refrigerant in the refrigerant for flowing to throttle part 3 is created a further reduction, be conducive to protect
The refrigerant that card flows to throttle part 3 is liquid.
As shown in Figure 1, in the present embodiment, evaporator 1 includes the first pipeline 11 being connected to throttle part 3 and is connected to
The first fin 12 on one pipeline 11, heat exchanging part 2 include the second pipeline 21 being connected to throttle part 3 and are connected to the second pipeline

It sets.
In further embodiments, evaporator 1 includes the first pipeline 11 being connected to throttle part 3 and is connected to the first pipe
The first fin 12 on road 11, heat exchanging part 2 include the second pipeline 21 being connected to throttle part 3, the second pipeline 21 and the first wing
Piece 12 connects.
In further embodiments, heat exchanging part 2 is arranged below evaporator 1, in order to produce in heat exchanging part 2 and evaporator 1
Raw condensed water heat exchange, so that evaporator 1 and heat exchanging part 2 exchange heat using condensed water as heat exchange medium.
Optionally, air conditioner indoor unit further includes the condensation water collection component that the lower section of evaporator 1 is arranged in, and heat exchanging part 2 is set
In condensation water collection component.
Discharge outlet is provided on condensation water collection component, discharge outlet is higher than the bottom surface of condensation water collection component, so that condensation
Water collecting part has condensed water, and heat exchanging part 2 is at least partly lower than discharge outlet, so that at least part of heat exchanging part 2 is soaked
In condensed water.
According to the flow direction of air conditioner refrigerant in cooling mode, the heat exchanging part 2 of air conditioner indoor unit is located at air conditioner indoor unit
Refrigerant inlet downstream and be located at throttle part 3 upstream.The principle of the work of air conditioner are as follows: passed through by compressed refrigerant
The refrigerant that becomes medium temperature high pressure is crossed in the condenser in air-conditioner outdoor unit after condensing, and then the refrigerant is by air conditioning chamber
The heat exchanging part 2 of interior machine is cooled down by the cold wind of the cold pipe of evaporator 1, blowout, is carried out to the refrigerant of medium temperature high pressure
It is cold, the temperature of refrigerant is reduced, the content of gaseous refrigerant in the refrigerant for flowing through throttle part 3 is reduced, to reduce system
Cryogen flows through the noise generated when throttle part 3.
According to another aspect of the present invention, the present embodiment additionally provides a kind of air conditioner, which includes above-mentioned sky
