In addition, above-mentioned indoor heat exchanger 5 has first heat exchanger 13 and second heat exchanger 14 of arranged in series, and above-mentioned first heat exchanger 13 is connected with the main channel 16 that second heat exchanger, 14 usefulness have switch valve 15.In addition, above-mentioned switch valve 15 apparatus have the throttling passage 18 of capillary 17 to make its bypass.In this case, be provided with rectification part 19,19 in the centre of throttling passage 18.
Promptly, as shown in Figure 2, on main channel 16, side (inlet side) and downstream (outlet side) are respectively equipped with forked section 20,21 at its upstream, the upstream side bifurcated pipe 22 that comes out from forked section 20 bifurcateds of upstream side is connected the upstream extremity of capillary 17, and is connected the downstream of capillary 17 from the downstream bifurcated pipe 23 that forked section 21 bifurcateds in downstream come out.And above-mentioned rectification part 19 inserts in each bifurcated pipe 22,23.As shown in Figure 3, this rectification part 19 is that the rolling piece 25 that forms with laminal mesh (so-called screen cloth) is wound into the roller shutter shape constitutes.In addition, the rolling piece 25 of the drum that so the forms direction that is arranged to its axial line is crossed the flow direction of throttling passage 18 along cryogen flow.In addition, when forming rolling piece 25, can be to the left or to the right, reel to any one direction, in addition, the density degree of employed screen cloth can have various selections, but, formed rolling piece 25 must as hereinafter said, can reach and make flowing refrigerant mobile equably, and can eliminate the purpose of its sound.
Carry out the refrigeration running according to the air-conditioning function of above such structure, warming operation and heated drying running again.When refrigeration running and warming operation, the switch valve 15 of main channel 16 is in full-gear, and expansion valve 4 is controlled under the predetermined aperture state simultaneously, and drives each fan F1, F2.Then, when refrigeration is turned round, four-way change-over valve 2 is transformed into the state shown in the solid line, drive compression machine 1.Like this, refrigerant just flows according to following flow process: compressor 1 → four-way change-over valve 2 → outdoor heat exchanger 3 → expansion valve 4 → indoor heat exchanger 5 (the one the second heat exchanger 13,14) → four-way change-over valve 2 → air accumulator 12, outdoor heat exchanger 3 plays condenser, and indoor heat exchanger 5 (first, second heat exchanger 13,14) plays evaporimeter, carries out the refrigeration running.
In addition, when warming operation, four-way change-over valve 2 is transformed into the state shown in the dotted line, drive compression machine 1.Like this, refrigerant just flows according to following flow process: compressor 1 → four-way change-over valve 2 → indoor heat exchanger 5 (first, second heat exchanger 13,14) → expansion valve 4 → outdoor heat exchanger 3 → four-way change-over valve 2 → air accumulator 12, indoor heat exchanger 5 (the one the second heat exchanger 13,14) plays condenser, and outdoor heat exchanger 3 plays evaporimeter, carries out warming operation.
Secondly, when heated drying turns round again, make expansion valve 4 be in full-gear, and make the switch valve 15 of main channel be in closed condition, four-way change-over valve 2 is transformed into the state shown in the solid line, stop outdoor fan F1, the internal fan F2 of drive chamber, drive compression machine 1. is when drive compression machine 1 in this state then, refrigerant flows in throttling passage 18, first heat exchanger 13 of indoor heat exchanger 5 plays condenser, and second heat exchanger 14 plays evaporimeter. like this, just can be after second heat exchanger 14 of having used the evaporimeter effect be with room air cooling and dehumidifying, used first heat exchanger 13 of condenser effect to be heated again, make it in the return chamber. promptly, can mix the air after cooling and the reduction humidity with utilizing the air after reheater (first heat exchanger 13) heats, make the suitable salubrious air of temperature. in addition, in this running of heated drying again, though also can allow outdoor heat exchanger 3 play condenser, but, as mentioned above, because fan F1 is in halted state, outdoor heat exchanger 3 ambient airs have not circulated, so be very limited by 3 heat exchanges that can carry out of outdoor heat exchanger.
As mentioned above, in this case,, can bring into play the effect that suppresses vibration owing in the middle of throttling passage 18, be provided with rectification part 19,19.This is because the refrigerant (gas-liquid two-phase fluid) that flows through above-mentioned throttling passage 18 homogenising in this rectification part 19,19 has reduced the pulsation and the Analysis of Pipe Vibrations of refrigerant.Particularly, by means of the rectification part 19 that is arranged in capillary 17 upstream sides, gas-liquid two-phase fluid by before the capillary 17 with regard to homogenising, under this homogenising state by behind the capillary 17, pressure has reduced.Like this, just reduce discontinuous sound, can obtain the effect of good inhibition vibration.In addition,, can make post-decompression refrigerant rectification (homogenising), also help to suppress vibration by means of the rectification part 19 that is arranged in capillary 17 downstreams.Like this, when rectification part 19,19 all is set in the upstream side of capillary 17 and downstream, just can reach the effect that suppresses vibration more effectively, can make indoor space become the suitable and space with fresh air of temperature than only rectification part being set in a side.

Like this,, outside the effect of pulsing, can also play the liquid homogenising, can make indoor quiet more by rectification part 19 by means of the inhibition of silencer 27 according to the throttling passage 18 shown in Fig. 7, Fig. 9, Figure 10 and Figure 11.
Secondly, in Figure 12, such the throttling passage 18 shown in upstream side bifurcated pipe 22 image patterns 6, be arranged on the position of the refrigerant flow priority that is rich in gas, and, the silencer 27. of having arranged the rectification part 19 of packing in this root upstream side bifurcated pipe 22 in addition, in Figure 13, upstream side bifurcated pipe 22 is arranged to protrude to vertical direction from forked section 20, and then the silencer 27. that has inserted the rectification part 19 of packing in upstream side bifurcated pipe 22 and downstream bifurcated pipe 23 like this, in these cryogen circuits, the same with the cryogen circuit shown in Fig. 6, can pulse seldom stable running (refrigerant cycle).
In addition, in Figure 14, instead of the rectification part 19 that is made of rolling piece 25 shown in Fig. 3, in this case, refrigerant also is to flow along its direction of axis line with the rectification part 19 of the disc shaped object among Fig. 7 28.Like this, outside the effect that the inhibition of silencer 27 is pulsed, also added the effect that makes the liquid homogenising that is produced by rectification part 19, can make indoor quiet more.
Specific embodiment of the present invention more than has been described, but the present invention only limits to the foregoing description, can implement the embodiment of various variations within the scope of the invention.For example, as rectification part 19, also can be the parts of alveolate texture, perhaps metalwork of punching press etc.In addition, in the throttling passage 18 as shown in Fig. 2, Fig. 4, Fig. 5 and Fig. 6, be to use the disc-shaped part 28 shown in Fig. 8 as rectification part 19, but, in the throttling passage shown in Fig. 7, Fig. 9, Figure 10, Figure 11, Figure 12 and Figure 13 18, then can use the such rectification part of rolling piece 25 as shown in Figure 3.Also have, in bifurcated pipe 22,23, arrange under the situation of rectification part 19, can use disc-shaped part 28 a side, and use rolling piece 25 the opposing party.In addition, being arranged on the quantity of the rectification part 19 in each bifurcated pipe 22,23, being not limited to one or two, also can be more than three.In addition,, must after the rectification function and the pressure loss of considering it, determine the density degree and the coiling number of turns (under the situation of rolling piece 25) of screen cloth for rectification part 19, and gauge (under the situation of disc-shaped part 28) or the like.In addition, in the figure of Fig. 2 etc., rectification part 19 is to be arranged near the gateway of throttling passage 18, promptly near the upstream extremity of bifurcated pipe 22 and near the downstream of bifurcated pipe 23, but, as the position of arranging rectification part 19, also can be near capillary 17, perhaps at the middle body of bifurcated pipe 22,23.Shown in the figure of Fig. 7 etc., under situation,, also can be arranged in it near the upstream extremity or near the downstream except silencer 27 being arranged in the middle body of bifurcated pipe 22,23 with silencer 27.
