As shown in Figure 1, the air conditioner of present embodiment is by constituting with inferior part: compressor 1, for switching the cross valve 2 that room cooling running and room add the operating condition of heat run etc., outdoor heat converter 3, when room cooling and room heating, make the main throttling arrangement 4 of flow of refrigerant, the two way selected valve 5 that cold-producing medium is flow through in when running dehumidifying that is set up in parallel with main throttling arrangement 4, indoor heat converter 6a divided into two parts and 6b, the dehumidifying control valve 7 of the conduct dehumidifying throttling arrangement that series connection with it is provided with between indoor heat converter 6a and 6b, prevent reservoir 8 to compressor 1 refluence, outdoor fan 9 to outdoor heat converter 3 air-supplies, indoor fan 10 to indoor heat converter 6a and 6b air-supply.
In Fig. 2, valve body 23 is by constituting with inferior part, have valve port 31 and opening port 30 valve seat 36, be positioned at the valve rod 34 of position in the middle of it, with valve rod 34 integrally formed or be installed on valve body 35 on the valve rod 34, for the solenoid 20 that drives valve body 35, for the attractor 21 that attracts valve body 35, press the spring 22 that is attached to valve port 31 1 sides for making valve body 35.If to solenoid 20 energisings, then produce magnetic force on attractor 21, because the spring force of spring 22 and the attraction equilibrium of forces of attractor 21, the valve body 35 with valve rod 34 moves up and down in valve body 23.Because this valve body 35 moves, valve rod 34 moves up and down between valve seat 36, and amount of restriction changes.At this moment, also can set valve rod 34 transfers to from valve seat 36 and makes main refrigerant path 27 be in open state.
When the dehumidifying running, cold-producing medium flow into the on high-tension side refrigerant flow path 32 from the inlet pipe arrangement 33 of dehumidifying control valve, here by 2 refrigerant passage, flow into the refrigerant flow path 28 of low-pressure side, flows out from outlet pipe arrangement 29.At this, refrigerant passage after shunting, be the main refrigerant path 27 that constitutes of the gap with 36 of valve rod 34 and valve seats and space 24 that in valve body 23, forms by the refrigeration path 25 and the perforation in the space 34 that connects on high-tension side refrigerant flow path 32 and valve body 23 in, forms and low-pressure side refrigerant flow path 28 be set at the secondary refrigerant passage that the refrigerant passage 26 in the valve excellent 34 constitutes.And then, be formed at the space 24 in the valve body 23, even utilize the gap of driving mechanism etc., also can in valve body 23, form stream.
Dehumidifying control valve shown in Figure 3 is identical with the basic comprising of dehumidifying control valve shown in Figure 2, but the inlet 37 of secondary refrigerant passage is set at the upper end of refrigerant flow path 32.Therefore, when cold-producing medium flows under the situation of dehumidifying control valve with gas-liquid two-phase fluid, general except that vertical pipe arrangement, gaseous refrigerant 38 flows on the upper strata, and liquid refrigerant 39 flows in lower floor, thereby, in main refrigerant path 27, the liquid refrigerant 39 that mainly flowing is in secondary refrigerant passage 25, the gaseous refrigerant 38 that mainly flowing can make refrigerant air-liquid flow discretely.At this moment, as the valve port 31 of the inlet of main refrigerant path 27, wish to be arranged at for the inlet 37 of secondary refrigerant passage 25 lower end side at the high-pressure side on its opposite refrigerant flow path 32.In addition, gas-liquid separating function is big with on high-tension side refrigerant flow path 32 effect when horizontal level is provided with at least at inlet pipe arrangement 33.
And then, as shown in Figure 4, in Fig. 2 or dehumidifying control valve shown in Figure 3, be connected the secondary refrigerant passage 25 that is provided with on high-tension side refrigerant flow path 32, also can utilize the gap between valve body 23 and the valve rod 34.Nonetheless constitute, also can with above-mentioned shunting function and the gas-liquid separating function that similarly has refrigerant fluid.
As mentioned above, constitute as shown in Figure 1 by making circulation, the structure that makes the dehumidifying control valve just can be worked as Fig. 2, Fig. 3 or Fig. 4 as described below.
When the room cooling operation, close two way selected valve 5, open dehumidifying throttling arrangement 7.At this moment, do not open as almost having the pressure loss as the valve rod of the dehumidifying control valve of dehumidifying throttling arrangement 7 action and the aperture area of valve seat.Its result, cold-producing medium is such shown in solid arrow among Fig. 1, sequential loop according to compressor 1 → time logical valve 2 → outdoor heat converter 3 → main throttling arrangement 4 → indoor heat converter 6a → dehumidifying throttling arrangement 7 → indoor heat converter 6b → cross valve 2 → reservoir 8 → compressor 1, with outdoor heat converter 3 as condenser, with indoor heat converter 6a and 6b as evaporimeter, in the cool room.
When the room adds heat run, by switching cross valve 2, make cold-producing medium shown in the dotted arrow direction, sequential loop according to compressor 1 → cross valve 2 → indoor heat converter 6b → dehumidifying throttling arrangement 7 → indoor heat converter 6a → main throttling arrangement 4 → outdoor heat converter 3 → cross valve 2 → reservoir 8 → compressor 1, with outdoor heat converter 3 as evaporimeter, with indoor heat converter 6a and 6b as in the condenser heating clamber.
When the dehumidifying running, similarly switch cross valve 2 during with room cooling running, open two-port valve 5, close dehumidifying throttling arrangement 7.At this moment, the valve rod 34 of the dehumidifying control valve that uses as dehumidifying throttling arrangement 7 descends, and is arranged in valve seat 36, constitutes main refrigerant path 27 and secondary refrigerant passage 25, and cold-producing medium is reduced pressure respectively by these 2 paths the time.Its result, cold-producing medium is such shown in single-point line among Fig. 1, sequential loop according to compressor 1 → cross valve 2 → outdoor heat converter 3 → two-port valve 5 → indoor heat converter 6a → dehumidifying throttling arrangement 7 → indoor heat converter 6b → cross valve 2 → reservoir 8 → compressor 1, by the throttling action of dehumidifying control valve as dehumidifying throttling arrangement 7, with the condenser of outdoor heat converter 3 as upstream side, with indoor heat converter 6a as the condenser in downstream, with indoor heat converter 6b as evaporimeter.And, by in indoor heat converter 6b, carrying out the cooling of room air.In the time of dehumidifying, add hot-air in indoor heat converter 6a, just can frontier defense end room temperature decline, running dehumidifies on the limit.
And then, in this case, by changing the condensation ability in outdoor heat converter 3 or the power of compressor 1, just can change the condensation ability among the indoor heat converter 6a, promptly change heat dissipation capacity, thus the air themperature that can blow out by indoor fan 10 in the wide scope inner control that heats to the room of freezing from the room.In addition, indoor heat converter 6a and 6b also can be set up in parallel in front and back, by indoor fan 10 wind are blown to 6a from indoor heat converter 6b, perhaps, are set up in parallel up and down, by indoor fan 10 wind are blowed to indoor heat converter 6a and 6b abreast.
Here, in above-mentioned dehumidifying running, because the operating condition of temperature and humidity conditions, compressor and the fan of indoor and outdoor etc., refrigerant fluid becomes the gas-liquid two-phase state at the inlet of dehumidifying throttling arrangement 7.In addition, according to circumstances, the channeling of shell shape becomes bulk stream and the plug flow that flows intermittently sometimes in this gas-liquid two-phase fluid in fluid liquid.To be called top be gaseous state and also become sometimes, and the bottom is the laminar flow of liquid two-phase and the fluid of wave flow.If cold-producing medium flows into dehumidifying throttling arrangement 7 under this gas-liquid two-phase flow body state, if the position that exists gas-liquid two-phase intermittently to flow in the part of fluid then produces the intermittently mobile sound of shape at this, this sound that intermittently flows becomes ear-piercing sound.And, because dehumidifying throttling arrangement 7 is set at an indoor side, therefore indoor people is felt bad.But, in the air conditioner of present embodiment,,,, the momentum that refrigerant fluid had, the kinetic energy that become exciting force are dissipated so can make refrigerant flow decentralized owing to formed 2 refrigerant passage even gas-liquid two-phase fluid is flowing.In addition, owing to carry out gas-liquid separation, thereby can guarantee the liquid refrigerant stream, prevent the throttling obstruction that causes by gaseous refrigerant.Its result can reduce the flow of refrigerant sound that is produced by gas-liquid two-phase refrigerant fluid.
In dehumidifying control valve shown in Figure 5, secondary refrigerant passage only is set in the valve rod 34.This secondary refrigerant passage is made of cross-drilled hole 40 and vertical hole 41.Refrigerant fluid from cross-drilled hole 40 flows into changes flow direction in vertical direction in valve body 34, flows out to the refrigerant flow path 28 of low-pressure side from vertical hole 41.At this moment, owing to the top that cross-drilled hole 40 is arranged on high-tension side refrigerant flow path, thereby, fashionable when cold-producing medium with biphase gas and liquid flow, also gas-liquid separating function can be arranged.Even under the situation of the dehumidifying control valve that has used this structure, also identical with the above embodiments, can seek to dissipate corresponding to the momentum, the kinetic energy that become the exciting force that the shunting by refrigerant fluid produces of the refrigerant fluid of gas-liquid two-phase, the effect that reduces its mobile sound is arranged.
Another embodiment of present embodiment is described by Fig. 6.Fig. 6 is the figure of formation that shows the freeze cycle of present embodiment.
In the present embodiment, showed the main throttling arrangement and the two-port valve of the freeze cycle that replaces embodiment shown in Figure 1, Fig. 2 has been arrived dehumidifying control valve shown in Figure 5, as shown in Figure 6 as the freeze cycle under expansion valve 12 operating positions.Expansion valve 12 need have been set throttling action for when the room cooling operation, and when the dehumidifying running, need set the state that does not almost have the pressure loss for.As expansion valve 12, no matter to use from Fig. 2 to any dehumidifying control valve shown in Figure 5, the function that can both use the freeze cycle shown in 6 is identical with the function of freeze cycle shown in Figure 1.In addition, using Fig. 2,, also can be reduced in the flow of refrigerant sound that produces in the expansion valve 12 even cold-producing medium flows into expansion valve 12 with the state of gas-liquid two-phase flow body to dehumidifying control valve shown in Figure 5 a certain during as expansion valve 12.
In the present embodiment, showed the example that constitutes with electromagnetic valve coil, attractor, spring as the valve rod drive unit of dehumidifying control valve, but also be suitable for to use motor device, mechanicalness device driven, use temperature sensing tube by pressure controlled device, and, also can be suitable for various formations according to driving method.In addition, the structure of valve is the structure that the valve rod moves in valve seat, as long as main refrigerant path and secondary refrigerant passage are set.And in the present embodiment, the part of secondary refrigerant passage is arranged in the valve rod, but the path (diagram is omitted) of the refrigerant flow path that connects on high-tension side refrigerant flow path and low-pressure side also can be set on valve body, and can reduce the flow of refrigerant sound equally.
Relevant can the refrigeration more than has been described, the kind of refrigeration cycle of heating, 3 operating conditions of dehumidifying, but be not limited in this, also can be suitable for other freeze cycle.For example, in Fig. 1 or freeze cycle shown in Figure 6, even freeze cycle in the room cooling operation that can not establish cross valve 2 and the running of the dehumidifying under the room kind of refrigeration cycle, promptly, indoor heat converter 6b, reservoir 8, compressor 1, outdoor heat converter 3 are under the situation of be connected in series (omitting among the figure), owing to be suitable for the embodiment shown in any one among Fig. 2 to Fig. 5, thereby, in the dehumidifying running, the flow of refrigerant sound that generation produces in dehumidifying throttling arrangement part similarly can fall.
In addition, in Fig. 1 or freeze cycle shown in Figure 6, when the room that cross valve 2 can be set adds heat run and adds in the room under the freeze cycle of the dehumidifying running under the heat run, promptly, outdoor heat converter 3, reservoir 8, compressor 1, indoor heat converter 6b are connected in series under the situation of (diagram omit), be suitable for any embodiment of Fig. 2 to Fig. 5, in the dehumidifying running, can be reduced in the flow of refrigerant sound that produces in the dehumidifying throttling arrangement part equally.
Have again, in the formation of Fig. 1 or freeze cycle shown in Figure 6, reservoir needn't non-ly be arranged, can be according to kind or the kind of main throttling arrangement and the freeze cycle that control method is provided with no reservoir of employed compressor.
And, can use the unitary system cryogen of the general employed HCFC22 of present air conditioner etc., and substitute a kind of mix refrigerant of alternative refrigerant that damages the ozone layer and make the HCFC22 of global warmingization as the kind that is flowing in the cold-producing medium in the kind of refrigeration cycle.If particularly use mix refrigerant, when the gas-liquid two-phase refrigerant fluid flows into throttling place, it is generally acknowledged that intermittence or continuous flow of refrigerant sound are very loud, if but be suitable for the above embodiments as mentioned above like that, just have the effect of seeking to fall the flow of refrigerant sound.
In the various embodiments described above, suppose that room air conditioner is illustrated, but be not limited thereto, on the device of needed other purposes of running that also goes for dehumidifying.In this case, generally do not limit heat exchanger and be used for indoorly or outdoor, this situation claims that indoor heat converter is to use the side heat exchanger, and outdoor heat converter is the heat source side heat exchanger, and indoor fan is for using the crosswind fan, and outdoor fan is the heat source side fan.
As described above in detail, if adopt air conditioner of the present invention, then with indoor heat converter (use side heat exchanger) separated into two parts, the dehumidifying throttling arrangement that uses when being arranged on the dehumidifying running betwixt, when the dehumidifying running, with the side that uses the side heat exchanger as evaporimeter, with the opposing party as condenser, carry out the cooling of air by freeze cycle.In the freeze cycle of dehumidifying and heating, by in the dehumidifying throttling arrangement, forming the main refrigerant path that links valve port and opening port, with 2 paths of secondary refrigerant flow path that high-pressure side refrigerant flow path and low-pressure side refrigerant flow path are communicated with that connect valve rod and valve body, make refrigerant flow path be divided into 2 the tunnel, the kinetic energy and the momentum that just can disperse each stream to have.In addition, by the ingate of the on high-tension side refrigerant flow path of secondary refrigerant passage is set in the stream upper end, just can make it have gas-liquid separating function, when refrigerant fluid is monophasic fluid, even under the situation of gas-liquid two-phase flow body, also can reduce the flow of refrigerant sound that sends by refrigerant fluid certainly by the dehumidifying control valve.In addition, because the above-mentioned heating efficiency that is caused by freeze cycle is bigger, thus can be under quiet state, the comfortable dehumidifying running that room temperature is descended and humidity is descended.
