Referring to fig. 3, the utility model also provides an adopt the air conditioner of gradual change combined type throttle capillary, the solid arrow indicates refrigerant flow direction when refrigerating in the picture, and the dotted arrow indicates refrigerant flow direction when heating to 3HP decides the frequency machine as an example, and this air conditioner includes indoor set and off-premises station, the indoor set includes indoor heat exchanger 3, gradual change combined type throttle capillary 4, filter 5, the first capillary of gradual change combined type throttle capillary 4 and the heat exchange card union coupling of indoor set, the second capillary is connected with the liquid pipe distributor 18 of indoor set, filter 5 passes through pipeline and 4 intercommunications of gradual change combined type throttle capillary. As can be seen from fig. 3, the tapered compound throttling capillary 4 of the present embodiment has six paths. The outdoor unit comprises a compressor 6, a liquid storage device 7, a four-way valve 8, a first filter 9, an upper outdoor heat exchanger 10, a lower outdoor heat exchanger 11, a supercooling coil pipe 12, a throttling assembly and a second filter 13, the compressor 6 is communicated with the liquid storage device 7 and the four-way valve 8, the first filter 9 and the liquid storage device 7 are also communicated with the four-way valve 8, the upper outdoor heat exchanger 10 and the lower outdoor heat exchanger 11 are respectively communicated with the four-way valve 8, the supercooling coil pipe 12 is respectively connected with the upper outdoor heat exchanger 10 and the lower outdoor heat exchanger 11, the throttling assembly is respectively connected with the supercooling coil pipe 12 and the second filter 13, the throttling assembly comprises a cold room capillary tube 14, a warm room capillary tube 15 and a one-way valve 16, the cold room capillary tube 14 is connected with the one-way valve 16 in series, and.

The pipes between the indoor and outdoor units are connected by an operation valve 17.
Taking refrigeration as an example, the following working principle is explained: the refrigerant discharged from the compressor 6 is cooled by the outdoor heat exchanger, is primarily throttled by the cooling capillary tube 14 of the outdoor unit, enters the indoor unit through the liquid pipe stop valve 17, has small pressure change, and then is throttled by the gradual change composite throttling capillary tube 4 to rapidly flow into the indoor heat exchanger 3. The pressure is sharply reduced after the throttling of the thin capillary tube, the flow speed is rapidly increased, then the flow speed is properly reduced after the flow speed enters the thick capillary tube, the flow speed is buffered and then enters the indoor heat exchanger 3, the tube diameter is suddenly increased, the pressure is continuously reduced, then the liquid refrigerant is changed into a gaseous refrigerant due to the reduction of the pressure, and the refrigerant is evaporated after absorbing heat, so that the indoor temperature is rapidly reduced. When the refrigerant enters the coarse capillary tube from the fine capillary tube, the volume change is relatively small, the flow speed of the refrigerant is slowed down, and compared with the refrigerant directly entering the indoor heat exchanger 3 from the common capillary tube, the refrigerant flowing sound caused by the sudden change of the state of the refrigerant caused by the sudden change of the refrigerant directly entering the indoor heat exchanger 3 from the common capillary tube can be effectively eliminated, so that the noise caused by the sudden change of the state of the refrigerant can be effectively eliminated.
