Fig. 4 is refrigerant stream of the air conditioner room unit according to an embodiment of the invention under common and heating clothes-drying mode
Road schematic diagram.
Referring to Fig. 4, air conditioner has the outdoor unit being connected with indoor set 1.Compressor, outdoor four are provided with outdoor unit
Port valve 54, outdoor heat exchanger, exoelectron expansion valve 52 and exogenous wind machine composition outdoor unit heat-exchange system.When indoor set 1 works in
When heating mode, common clothes-drying mode in heat exchange pattern and heating clothes-drying mode, outdoor four-way valve 54 is configured to make refrigerant
The heat-exchange system of machine 1 is got in from the refrigerant pipeline for being now placed in the upstream of First Heat Exchanger 101, is now placed in the second heat exchanger certainly
The refrigerant pipeline outflow heat-exchange system of indoor set 1 in 201 downstreams.
As shown in figure 4, the First Heat Exchanger 101 in indoor set 1 can be connected with the second heat exchanger 201 by refrigerant pipeline,
Further, interior electric expansion valve 51 is may be provided with refrigerant pipeline to control cold medium flux and adjust its temperature.
In some embodiments of the invention, First Heat Exchanger 101 is configured to the controlled heating under any clothes-drying mode, with
The air for flowing through it is heated.Further, indoor set is by being arranged between First Heat Exchanger and the second heat exchanger
Interior electric expansion valve, adjust the cold medium flux that the second heat exchanger is flowed to from First Heat Exchanger.Interior electric expansion valve is configured in room
When interior machine works in common clothes-drying mode, default less first aperture of aperture is kept, so that the second heat exchanger 201 is general
Controlled refrigeration under logical clothes-drying mode, to be cooled down to the air for flowing through it.
It that is to say, when indoor set 1 is in common clothes-drying mode, interior electronic expansion valve opening is smaller, with to being changed from first
The refrigerant that hot device 101 flows to the second heat exchanger 201 carries out decompression throttling, refrigerant is evaporated rapidly after entering the second heat exchanger 201
Heat absorption, fast cooling and dehumidifying thus are carried out to the damp-heat air for flowing through the second heat exchanger 201.
Specifically, surrounding air can be sucked into casing in the presence of the first blower fan 100 and enter in first chamber 10, and
Heat exchange forms the high-temperature gas of relatively dry in the presence of First Heat Exchanger 101.Then, the high-temperature gas is by the first blower fan
100 blow in the 3rd chamber 30 and flowing through storage and have the drying module of wet clothes.High-temperature gas is taken away in wet clothes
Moisture forms high-temperature high-humidity air-flow, and is sucked into the presence of the second blower fan 200 in second chamber 20.Into the second chamber
Second heat exchanger 201 of the damp and hot air flow contacts refrigerating operaton in room 20 condenses, and forms the dry air of temperature reduction
Casing is blown from out to return in surrounding environment.
The indoor set 1 of the present invention has what can be sequentially communicated to be used to be formed the first chamber 10 of drying air-flow, for placing
3rd chamber 30 of wet clothes and the second chamber 20 for cooling and dehumidifying, its connect wind path in form lasting drying gas
Stream, to continue relatively dry in first chamber 10 and the higher drying air-flow of temperature being blown into the 3rd chamber 30, and by the 3rd chamber
Moisture in the larger air of relative humidity in the drying module of room 30 is taken away, and forms damp-heat air, and by the damp and hot sky
Gas is sucked into second chamber 20, and is made by the second heat exchanger 201 of operation refrigeration in it in the larger air of the humidity
Condensate moisture, to carry out cool-down dehumidification to the damp-heat air, then dried blow air is returned in indoor environment.
Thus, indoor set 1 of the invention can avoid damp-heat air caused by drying from being flowed directly out from indoor set 1 to indoor ring
Border, make to have an impact the temperature and humidity of indoor environment in the air conditioner for carrying out drying, effectively prevent indoor set 1
Made troubles under clothes-drying mode to indoor user or uncomfortable sensation, and sustainably providing and dry comfortable air
Promote indoor air circulation.
Further, outdoor four-way valve 54 and indoor four-way valve 53 can be configured to：Machine works in heating drying mould indoors
During formula, refrigerant is set to flow through First Heat Exchanger, electric expansion valve, the second heat exchanger and outdoor heat exchanger successively from after compressor outflow
After flow back to compressor so that First Heat Exchanger is heated with the first temperature, the second heat exchanger is heated with second temperature.Now, it is interior
The aperture of electric expansion valve may be configured as maximum opening or be arranged to the larger default aperture of an aperture.
Specifically, because the refrigerant for entering the second heat exchanger carried out a heat exchange in First Heat Exchanger, with
And the metering function due to interior electric expansion valve, second temperature can be less than the first temperature, to flow through the cooling of its damp-heat air
Condensation, so as to realize dehumidifying.It that is to say, indoor set 1 can realize system by heating clothes-drying mode while clothes drying function is run
Heat.Heating clothes-drying mode has identical wind path and refrigerant flow with common clothes-drying mode.First Heat Exchanger 101 and second exchanges heat
Device 201 can run heating simultaneously, but the heating temperature of the second heat exchanger 201 is less than First Heat Exchanger 101, so that with the 3rd
The damp atmosphere formed in chamber 30 temperature when entering second chamber 20 and slightly lower the second heat exchanger 201 of Contact Temperature drops
It is low, and blowed again via the second air outlet 22 into surrounding environment after its interior moisture separates out and realizes dehumidifying.
Further, in some embodiments of the invention, interior electric expansion valve 51 can be configured to machine indoors and work in
Heat clothes-drying mode in the case of, when ambient humidity is more than default humidity threshold, in reduction electronic expansion valve opening to preset
The second aperture so that the second heat exchanger it is controlled refrigeration until ambient humidity be down to humidity threshold.
Alternatively, interior electric expansion valve 51 can be further configured to when ambient humidity is more than default top limit of humidity threshold value
When, reduce aperture to default second aperture so that the controlled refrigeration of the second heat exchanger is until ambient humidity reaches under default humidity
Limit threshold value.
It that is to say, when indoor set 1 works in heating clothes-drying mode, if indoor environment humidity is less than or equal to humidity threshold,
Then interior electric expansion valve 51 may be configured as maximum opening or larger opening, so that the second heat exchanger heats, if indoor environment humidity
More than humidity threshold, then interior electric expansion valve 51 reduces the aperture under aperture to common clothes-drying mode, so that the second heat exchanger system
It is cold.
Thus, when air conditioner runs heating clothes-drying mode, First Heat Exchanger and the second heat exchanger heat simultaneously first, this
When the second heat exchanger temperature be slightly below First Heat Exchanger, the condensation to damp-heat air is relatively weak, that is to say one
The air more moistened is divided directly to flow back to interior.Now, the sustainable monitoring air-conditioning of humidity sensor set on air conditioner is attached
The ambient humidity of nearly room air, when ambient humidity is more than default top limit of humidity threshold value, the second heat exchanger 201 is controlled
It is cold.Until when ambient humidity is decreased below equal to default humidity lower threshold, the 201 controlled heating of the second heat exchanger.Environment
Humidity is the relative humidity of now surrounding environment, and the upper limit threshold of humidity can be arranged to 60% according to environment temperature and user's request
Moisture value between to 80%, such as top limit of humidity threshold value can be 80%, 70% or 60% etc..The lower threshold of humidity
50%, 40% or 30% etc. can be provided accordingly to.
It that is to say, the operation heating clothes-drying mode of indoor set 1 can increase indoor humidity.When indoor environment is more dried, on
Lower heat exchanger heats, and dries the partial moisture retained in air-flow and is blown from back outdoor environment.When indoor environment more moistens,
The second heat exchanger 201 positioned at downstream controlled can switch to operation to freeze, and thus, the most of moisture dried in air-flow is contacting
Condensed precipitation during the second heat exchanger 201, thus indoor set 1 more comfortable dry air-flow can be blowed to interior.
Fig. 5 is refrigerant flow signal of the air conditioner room unit according to an embodiment of the invention under the clothes-drying mode that freezes
Figure.
Referring to Fig. 5, when the refrigeration mode and refrigeration clothes-drying mode that indoor set 1 is worked in heat exchange pattern, outdoor four
Port valve 54, which configures switching state and refrigerant is got in machine 1 from the refrigerant pipeline for being now placed in the upstream of the second heat exchanger 201, to exchange heat
System, the refrigerant pipeline outflow heat-exchange system of indoor set 1 in the downstream of First Heat Exchanger 101 is now placed in certainly.
It that is to say, in some embodiments of the invention, outdoor four-way valve 54 and indoor four-way valve 53 are configured to：Indoors
When machine works in refrigeration clothes-drying mode, refrigerant is set to flow through outdoor heat exchanger, First Heat Exchanger, electronics successively from after compressor outflow
Compressor is flowed back to after expansion valve and the second heat exchanger, so that First Heat Exchanger is heated with the 3rd temperature, makes the second heat exchanger with
Four temperature refrigerations.Further, when indoor set 1 work in refrigeration clothes-drying mode when, interior electric expansion valve 51 be arranged to one compared with
Small aperture.Such as can be identical with the aperture of the interior electric expansion valve 51 when indoor set 1 works in common clothes-drying mode.
It that is to say, under the clothes-drying mode that freezes, the outdoor four-way valve 54 of outdoor unit and the indoor four-way valve 53 of indoor set are equal
Commutation, the HTHP refrigerant from compressor outflow is set first to flow through outdoor heat exchanger, temperature reduces but still relatively hot slightly
Refrigerant then flows into First Heat Exchanger via indoor four-way valve 53, makes First Heat Exchanger have the 3rd slightly lower temperature of temperature (should
Temperature remains above room temperature), now refrigerant is exchanged heat with flowing through the air of First Heat Exchanger, to cause the partial air to be heated shape
