Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
Embodiment one.
As shown in figure, a kind of air-conditioning system that can adjust heat exchange amount, including by compressor 1, four-way reversing valve 2, room
The refrigerant circulation circuit that external heat exchanger 3, indoor heat exchanger 8 and gas-liquid separator 9 are constituted.Wherein, the indoor heat exchanger 8 includes
The multiple groups being connected in parallel, every group is equipped with indoor electronic expansion valve 7, conveniently controls and uses.The outdoor heat exchanger 3 and interior
It is equipped with outdoor electrical expansion valve 6 between heat exchanger 7, can throttle to the refrigerant flowed through.
The outdoor heat exchanger 3 includes 48 refrigerant pipes 31, lines up 16 rows three column.6 refrigerant pipes 31 per adjacent 2 row
One group of refrigerant flow mutually is formed after concatenation, shares 7 groups.The connection type of every group of refrigerant flow is two refrigerant pipes 31 of each column
It is connected, then the adjacent refrigerant pipe 31 of each row is sequentially connected, enables refrigerant followed by every refrigerant pipe 31.Alternatively, can also
With using other connection types, the needs of to meet production or installation.7 groups of refrigerant flows are divided into first part and second
Part.Wherein, which includes 6 groups of refrigerant flows from top to bottom, and second part includes nethermost one group of refrigerant stream
Road.The arrival end of each group refrigerant flow in the first part is separately connected the four-way reversing valve 2, and outlet end is through liquid separation
Pipe 4 is connected after converging with the indoor heat exchanger 7；The arrival end of the refrigerant flow of the second part after orifice union 5 with
The output end of the separating tube 4 is connected, and outlet end is connected to the gas-liquid separator 9 after the four-way reversing valve 2.It is described
Orifice union 5 is the solenoid valve 51 and capillary 52 being serially connected.Wherein, the solenoid valve 51 can be used for the logical of control piper
Disconnected, the capillary 52 can throttle to refrigerant.
Embodiment two.
As shown in Figure 2.The present embodiment and the structure of embodiment one are essentially identical, and the main distinction is, first part removes
It further include the 7th group that 4 refrigerant pipes being originally in second part are constituted outside 6 groups of original refrigerant flows.Correspondingly,
Second part refrigerant flow in the present embodiment only includes 2 refrigerant pipes, to meet the needs of different user.
Embodiment three.
As shown in Figure 3.The present embodiment and the structure of embodiment one are essentially identical, and the main distinction is in section in this present embodiment
Stream component is an electric expansion valve 53, because it is provided simultaneously with control piper on-off and realizes the function of throttling, can make structure more
Add succinctly, and is easily installed and safeguards.
Operational process of the invention are as follows:
1. when refrigerating operaton, compressor absorbs low-temp low-pressure gaseous coolant in gas-liquid separator, and compresses it into high temperature and pressure
Gaseous coolant, then after four-way reversing valve point multichannel respectively enter in first part's refrigerant flow in outdoor heat exchanger into
Row heat exchange, is cooled to the liquid refrigerants of medium temperature high pressure, then after merging into all the way by liquid-dividing head, then through outdoor electrical expansion valve
With heat exchanger is entered the room after indoor electronic expansion valve, and absorb indoor environment heat and be gasificated into low-temp low-pressure gaseous coolant,
Then enter gas-liquid separator after again flowing through four-way reversing valve, eventually pass back to compressor, complete a refrigerant circulation.
When the load of indoor unit is smaller, the liquid refrigerants of the medium temperature high pressure come out from outdoor heat exchanger converges through liquid-dividing head
It is most of that indoor heat exchanger is flowed into after outdoor electrical expansion valve after stream, separately there is fraction to throttle through orifice union low at low temperature
The gas-liquid two-phase state refrigerant of pressure is directly entered tracheae after then flowing through second part refrigerant flow.At this point, the outdoor heat exchange
The first part of device generally condenser, second part are evaporator, can make up interior heat exchange caused by due to indoor demand is small
Device and the unmatched situation of outdoor heat exchanger load, make system stable operation.
2. when heating operation, compressor absorbs low-temp low-pressure gaseous coolant in gas-liquid separator, and compresses it into high temperature
The gaseous coolant of high pressure, then flows to indoor heat exchanger after four-way reversing valve, and release heat to indoor environment, is liquefied as
The liquid refrigerants of warm high pressure, then flows through indoor electronic expansion valve and the throttling of outdoor electrical expansion valve is cold at the liquid of low-temp low-pressure
After matchmaker, and it is divided into after liquid-dividing head the refrigerant flow that multichannel enters outdoor heat exchanger first part, keeps the liquid of low-temp low-pressure cold
Matchmaker absorbs the heat in external environment and is gasificated into the gaseous coolant of low-temp low-pressure, after passing through four-way reversing valve after then converging
Into gas-liquid separator, compressor is eventually passed back to, completes a refrigerant circulation.
When indoor unit operation at part load, indoor unit demand is smaller.At this point, orifice union is opened, compressor discharge
The gaseous coolant of high temperature and pressure largely flows to indoor heat exchanger after four-way reversing valve, and fraction flows to outdoor heat exchanger
Second part refrigerant flow exchanges heat, then through orifice union reducing pressure by regulating flow, becomes two phase refrigerants of low-temp low-pressure, then,
Converge with through the condensed main road refrigerant of indoor heat exchanger, flows to liquid-dividing head, thus, caused by compensating for due to indoor demand is small
Indoor heat exchanger and the unmatched situation of outdoor heat exchanger load, make system stable operation.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
