The specific embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is the structural representation of aircondition.Aircondition 1 is connected by pipe arrangement 4,5 with indoor set 3 by off-premises station 2 and constitutes.
The discharge pipe arrangement 11 that is connected in compressor 10 outlets in the off-premises station 2 is connected to the inflow entrance of outdoor heat converter 12.Connecting pipings 4 on the flow export of outdoor heat converter 12, and pipe arrangement 4 is provided with first decompressor 13 on its path, then extend to indoor set 3 sides.
Indoor set 3 has first heat exchanger 21 and second heat exchanger, 22, the first heat exchangers 21 and second heat exchanger 22 and almost is arranged in parallel on the air flow path that is formed by ventilating fan 23 (representing with arrow A in the accompanying drawing) by the order of second heat exchanger 22, first heat exchanger 21.The capacity of first heat exchanger 21 and second heat exchanger 22 much at one.The top of first heat exchanger 21 is provided with cold-producing medium inflow entrance 21A, and this inflow entrance 21A goes up connecting pipings 4.The flow export 21B of first heat exchanger 21 is located at its underpart, and this flow export 21B goes up connecting pipings 24.
In the central authorities of branching portion 25, promptly the extreme higher position connecting pipings 29.Pipe arrangement 29 extends to downside after upside almost prolongs by vertical direction from branching portion 25, second decompressor 30 is set in the way is connected on the pipe arrangement 27 afterwards.Specifically, pipe arrangement 29 is connected to than two-port valve 28 more near pipe arrangement 27 positions of second heat exchanger 22.
In addition, though second decompressor 30 also can be arranged on the air flow path (A), preferably be arranged in and depart from air flow path (A) part.And, as described below since through the path of pipe arrangement 29 always by open-minded, thereby the path of liquid reservoir 26 sides becomes the passage that is used for circuitous pipe arrangement 29 paths.
Cold-producing medium flow export 22B is formed at second heat exchanger, 22 its tops, and at this connecting pipings 5.Pipe arrangement 5 is connected to off-premises station 2, and is inserted into gas-liquid separation device 31 by upside.Extend suction pipe arrangement 32 from gas-liquid separation device 31, this suction pipe arrangement 32 is connected in the suction inlet of compressor 10.Compressor 10, first decompressor 13, two-port valve 28 and second decompressor 30 are by control device 40 controls.
The following describes the effect of present embodiment.
During refrigerating operaton, according to the direction circulating refrigerant shown in arrow B among Fig. 1.That is, control device 40 is set at predetermined aperture with first decompressor 13.And, open two-port valve 28 and open second decompressor 30 fully.When operation compressor 10, the high-pressure gas refrigerant of being discharged by compressor 10 flow into outdoor heat converter 12.Because first decompressor 13 is set to predetermined aperture, thereby gas refrigerant is condensed into liquid refrigerant in outdoor heat converter 12.Thus, the two phase refrigerant that reduces pressure by first decompressor 13 flows into indoor set 3.In the indoor set 3, two phase refrigerant is flowed into by the top of first heat exchanger 21, and carries out heat exchange with air-flow that ventilating fan 23 is discharged and downward side flow when evaporating.This two phase refrigerant is diverted to end 25A side and pipe arrangement 29 by pipe arrangement 24 at branching portion 25.Because branching portion 25 roughly is " U " font, even thereby be two phase refrigerant, also reduce and can pass through smoothly because of flow resistance.
Because two-port valve 28 is opened, thereby the cold-producing medium that flow to liquid reservoir 26 sides can not be trapped in the liquid reservoir 26, but flow into second heat exchanger 22.Because liquid reservoir 26 is arranged in the downstream side of air flow path (A), so liquid reservoir 26 can be used as evaporimeter.That is, the liquid refrigerant that flows through liquid reservoir 26 is by carrying out heat exchange with liquid reservoir 26 moving air on every side, and a part is vaporized and flows out to pipe arrangement 27.In addition, because second decompressor 30 is by open-minded fully, thereby the cold-producing mediums that flow to pipe arrangement 29 do not reduce pressure substantially, and converge with the cold-producing medium that flows through pipe arrangement 27 and flow into second heat exchanger 22.Two phase refrigerant is evaporated by heat exchange and forms saturated cold-producing medium or gas refrigerant in second heat exchanger 22.The air of discharging by ventilating fan 23 through first heat exchanger 21, second heat exchanger 22 is cooled and be discharged to indoor.The cold-producing medium that is flowed out by second heat exchanger 22 flow into off-premises station 2 by pipe arrangement 5, and is inhaled in each compressor 10 through gas-liquid separation device 31.Then, be compressed once more and be discharged on the discharge pipe arrangement 11.
When the heat dehumidifying moves again, according to the direction circulating refrigerant shown in arrow C among Fig. 1.That is, control device 40 is opened first decompressor 13 fully.Then, close two-port valve 28 and second decompressor 30 is set at predetermined aperture.When operation compressor 10, high-pressure gas refrigerant flow into outdoor heat converter 12.Because first decompressor, 13 quilts are open-minded fully, thereby make high-pressure gas refrigerant form liquid refrigerant by the outdoor heat converter 12 and first heat exchanger 21.At this moment, towards first heat exchanger 21 around heat release.The high pressure liquid refrigerant that flow out bottom by first heat exchanger 21 is divided to end 25A side and pipe arrangement 29 flows at branching portion 25.The liquid refrigerant that flows to end 25A flows into liquid reservoir 26, and owing to two-port valve 28 is closed, thereby liquid refrigerant will be trapped in the liquid reservoir 26.The liquid refrigerant that flows to pipe arrangement 29 is reduced pressure by second decompressor 30 and flow into second heat exchanger 22, is vaporized by heat exchange then.The heat-absorbing action ambient air cooling that dehumidified by this moment.By the air of second heat exchanger 22 dehumidifying cooling by ventilating fan 23 deliver to first heat exchanger 21 around, and be heated by the exothermic effects of first heat exchanger 21, be discharged to indoor thus as dehumidified air.The cold-producing medium that flows out from second heat exchanger 22 is inhaled into the compressor 10 of off-premises station 2, discharges through compressing once more then.
Because the part cold-producing medium is trapped in the liquid reservoir 26, thereby the refrigerant amount that causes circulating in aircondition 1 when the heat dehumidifying moves again reduces.The volume of liquid reservoir 26 is set to substantially poor corresponding to the refrigerant amount of the most suitable refrigerating operaton and refrigerant amount that the dehumidifying of the most suitable heat again moves.If be converted to refrigerating operaton from heat dehumidifying operation again, then since two-port valve 28 by open-minded, thereby the liquid refrigerant that is stranded in liquid reservoir 26 is supplied in second outdoor heat converter 22, and the refrigerant amount of circulation in aircondition 1 is increased.
According to above-mentioned embodiment, by the connection liquid reservoir 26 arranged side by side and second decompressor 30, and two-port valve 28 is located at liquid reservoir 26 1 sides forms circuitous channel with respect to second decompressor, 30 passages, thereby make refrigerating operaton and the coolant channel of heat dehumidifying operation is different again, therefore can carry out two heat exchangers 21,22 all as the refrigerating operaton of evaporimeter.And, when operation heat dehumidifying again, can residual refrigerant be collected in the liquid reservoir 26 reducing circulating mass of refrigerant by closing two-port valve 28, thereby can be respectively by the refrigerant amount of the best effectively carry out refrigerating operaton and again the heat dehumidifying move.
Owing to make cold-producing medium flow to second heat exchanger 22 from the bottom of first heat exchanger 21, thereby can be when forming liquid refrigerant in first heat exchanger 21 to second heat exchanger, 22 rapid trickle cold-producing mediums, so can the stagnant liquid cryogen in first heat exchanger 21.In view of the above, can keep the heat exchanger effectiveness of first heat exchanger 21 efficiently.
And, owing to be provided with the branching portion 25 that projects upwards at the pipe arrangement 24 that extends out from first heat exchanger 21, thereby can reduce the circulating resistance of two phase refrigerant to greatest extent, thus rapid divided gas flow cold-producing medium and liquid refrigerant.Can promptly reclaim the remaining liq cold-producing medium to liquid reservoir 26 when therefore, the heat dehumidifying moves again.
Because liquid reservoir 26 rows of being exposed to are on indoor air flow path (A), thereby can be with liquid reservoir 26 as evaporimeter during refrigerating operaton, thereby refrigerating efficiency can further be improved.In addition, because two-port valve 28 is arranged in the position of departing from air flow path (A), thereby two-port valve 28 can be exposed in the dripping of producing in first heat exchanger 21 and second heat exchanger 22.
The variation of branching portion shown in Fig. 2.Branching portion 50 shown in Fig. 2 roughly is " T " font, and the pipe arrangement 24 that prolongs from first heat exchanger 21 almost vertically is connected on branch's pipe arrangement 51.Branch's pipe arrangement 51 slight inclination, the end 51A that prolongs goes up and connects liquid reservoir 26 downwards.Upwards the end 51B that prolongs connects second decompressor 30.If flow into two phase refrigerant, then, thereby be easy to separating liquid cold-producing medium and gas refrigerant because the two phase refrigerant that flows through pipe arrangement 24 is impacted mutually with the inwall of branch pipe arrangement 51 to this branching portion 50.After refrigerating operaton was transformed into heat dehumidifying operation again, two phase refrigerant flowed in branch's pipe arrangement 51 till normal operation.At this moment, liquid refrigerant separates with gas refrigerant in branch's pipe arrangement 51, and liquid refrigerant will be stranded in the liquid reservoir 26.And gas refrigerant is supplied to second heat exchanger 22 by second decompressor 30.In view of the above, not participating in directly again, the residual refrigerant of the liquid refrigerant of heat dehumidifying operation is recycled in the liquid reservoir 26.That is, after the conversion operation, because rapidly to liquid reservoir 26 storaging liquid cold-producing mediums, thereby can shorten the excessive time that employed refrigerant amount is fit to the running status of hot dehumidifying operation again that arrives.
In addition, the present invention is not limited to above-mentioned embodiment and can be extensive use of.For example, liquid reservoir 26 can also be arranged on the air flow path (A) between second heat exchanger 22 and first heat exchanger 21.And the formation of off-premises station 2 and quantity are not limited to the content shown in the accompanying drawing.
