Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Air-conditioning system according to embodiments of the present invention is described with reference to the accompanying drawings.
Fig. 1 is the block diagram of air-conditioning system according to embodiments of the present invention, as shown in figure 1, the air-conditioning system 100 includes outdoor
Machine 10, indoor set 20 and controller (not indicated in figure).
Wherein, outdoor unit 10 includes compressor 11, four-way valve 12 and outdoor heat exchanger 13, can also include other pipes certainly
Road or part such as gas-liquid separator, wherein, the air outlet of the first valve port A connections compressor 11 of four-way valve 12, four-way valve 12
The second valve port D connections outdoor heat exchanger 13 one end, the gas returning port of the 3rd valve port C connections compressor 11 of four-way valve 12.
Indoor set 20 includes indoor main heat exchanger 21, indoor auxiliary heat exchanger 22, controlling switch 23 and throttling arrangement 24, its
In, one end of indoor auxiliary heat exchanger 22 is connected with the other end of outdoor heat exchanger 13, the other end and section of indoor auxiliary heat exchanger 22
One end of stream device 24 is connected, and the other end of throttling arrangement 24 is connected with one end of indoor main heat exchanger 21, indoor main heat exchanger
21 other end is connected with the 4th valve port B of four-way valve 12, one end of controlling switch 23 and one end phase of indoor auxiliary heat exchanger 22
Even, the other end of controlling switch 23 is connected with the other end of indoor auxiliary heat exchanger 22.
Controller 30 is controlled according to operational mode to controlling switch 23, wherein, in dehumidification mode, control control is opened
23 are closed to close.
Specifically, when running dehumidification mode, compressor 11 exports the refrigerant of HTHP, and refrigerant passes through four-way valve 12
Export to outdoor heat exchanger 13 to carry out condensation heat release, and then, the refrigerant of cryogenic high pressure gets in machine 20, and controlling switch 23 is closed
Closing, then refrigerant carries out condensation heat release again by indoor auxiliary heat exchanger 22, and by the throttling of throttling arrangement 24 as low-temp low-pressure
Refrigerant, refrigeration is evaporated by indoor main heat exchanger 21, and compressor 11 is being back to finally by four-way valve, so circulation.
As can be seen that the structure of the indoor set 20 based on the embodiment of the present invention, when running dehumidification mode, indoors when, pass through interior
Auxiliary heat exchanger 22 carries out condensation heat release, then by the indoor sweat cooling of main heat exchanger 21, it is thus possible to balance indoor temperature not
Become, meet the requirement that dehumidifying does not cool, indoor temperature when running that avoids dehumidifying is more and more lower and influences indoor comfort.
Mode for indoor heat exchanger to be divided into a part of evaporation another aspect condensation in correlation technique,
The problem of effect declines in normal refrigeration or heating, the air-conditioning system 100 of the embodiment of the present invention, based on interior above-mentioned
The structure of machine 20, wherein, indoor auxiliary heat exchanger 22 has capillary module, controller 30 in refrigeration mode or heating mode,
Control controlling switch 23 is opened, and is bypassed to be freezed or be heated, it is ensured that refrigeration or heating effect.
Specifically, under normal refrigerating mode, controller 30 controls controlling switch 23 to open, and indoor auxiliary heat exchanger 22 has
Capillary module, refrigerant flow resistance is larger, thus, when controlling switch 23 is opened, auxiliary heat exchanger 22 will not pass through substantially in room
Refrigerant, then refrigerant get in machine 20, flow through the pipeline of controlling switch 23, and enter by such as electric expansion valve of throttling arrangement 24
Row reducing pressure by regulating flow, then absorbing and cooling temperature is evaporated by indoor main heat exchanger 21, realize refrigeration.As can be seen that freezing
Under pattern, indoor auxiliary heat exchanger 22 does not work, similar with now air-conditioned process of refrigerastion, does not interfere with refrigeration.
Similarly, under normal heating mode, controller 30 controls controlling switch 23 to open, due to indoor auxiliary heat exchanger 22
With capillary module, cold-producing medium stream dynamic resistance is larger, in the case where controlling switch 23 is opened, base in indoor auxiliary heat exchanger 22
This does not pass through refrigerant.The refrigerant for the HTHP that compressor 11 exports gets in machine 20, flows through indoor main heat exchanger 21 and carries out
Heat release is condensed, then reducing pressure by regulating flow is carried out by throttling arrangement 24 and is changed into the refrigerant of low-temp low-pressure, while distributes each indoor set
Coolant quantity, then the pipeline by controlling switch 23 export to outdoor heat exchanger 13 be evaporated heat absorption, finally by four-way
Valve 12 is back to compressor 11, and heating is realized in so circulation.As can be seen that in cooling mode, indoor auxiliary heat exchanger 22 does not rise
Effect, it is similar with now air-conditioned heating operations, do not interfere with heating effect.
In addition, in some correlation techniques, it is now indoor if need defrosting for heating operation outdoor heat exchanger 13
Heat exchanger is also the heat in absorption chamber as evaporator, thus, cause indoor temperature to decline during defrosting, influence comfortable
Property.And in an embodiment of the present invention, can be with based on the indoor set 20 for setting indoor main heat exchanger 21 and indoor auxiliary heat exchanger 22
When ensureing operation defrosting, the indoor temperature of the indoor set 20 of running status is constant, ensures comfortableness.
In some embodiments of the invention, for multiple on-line system, in heating and defrosting pattern, at the acquisition of controller 30
The ratio of total indoor set capacity is accounted in the capacity sum of the indoor set of running status, and the capacity sum of the indoor set in operation accounts for
When the ratio of total indoor set capacity is less than preset ratio such as 50%, the controlling switch of indoor set 20 of the control in running status
23 close, and now, condensing exotherm in the indoor existing auxiliary heat exchanger 22 in interior of the indoor set 20 in running status also has
The indoor evaporation endothermic of main heat exchanger 21 cooling, can stablize indoor temperature as much as possible, can realize outdoor heat exchanger 11 again
Defrosting, and, the controlling switch of indoor set of the control in non-operating state is opened, that is, is sayed, is not needing the room of air-conditioning effect
Interior to carry out normal heating and defrosting, now, refrigerant bypasses by the pipeline of controlling switch 23, even if indoor main heat exchanger 21
As heat in evaporator absorption chamber, the problem of influenceing comfortableness is there will not be, indoor auxiliary heat exchanger 22 does not act on；Or
When the ratio that the capacity sum of the indoor set of operation accounts for total indoor set capacity is more than or equal to preset ratio, all interiors are controlled
The controlling switch 23 of machine is opened, and is bypassed by the pipeline of controlling switch 23, then is cooled by the indoor evaporation endothermic of main heat exchanger 21,
Realize outdoor defrosting function.
