Road A, valve road B, valve road C, valve road D.The electric expansion valve 4 includes electric expansion valve 4a and electric expansion valve 4b.The gas-liquid
Separator 7 has two mouths, respectively air inlet and gas outlet.The valve of the exhaust outlet of the compressor 1 and the four-way reversing valve 2
Road A is connected, and the air entry of the compressor 1 is connected with the gas outlet of gas-liquid separator 7；The valve road B of the four-way reversing valve 2
It is connected with one end of user terminal water source heat exchanger 3, the valve road C of the four-way reversing valve 2 and entering for the gas-liquid separator
Gas port is connected, and the valve road D of the four-way reversing valve is connected with one end of source water source heat exchanger 6；The user terminal water source
The other end of heat exchanger 3 is divided into two, and is connected respectively with one end of the electric expansion valve 4a and electric expansion valve 4b one end；
The other end of the electric expansion valve 4a is connected with one end of the source air source heat exchanger 5；The source air-source heat exchange
The other end of device 5 is divided into two, and is connected respectively with the other end of the electric expansion valve 4b and another with source water source heat exchanger 6
One end is connected.
The course of work of the present utility model is as follows：
During heating, electric on four-way reversing valve 2, now, the valve road A and valve road B of four-way reversing valve are communicated；Valve road C and valve road D
Communicate.Refrigerant is discharged by the exhaust outlet of compressor 1 after the compression of compressor 1, flows through 2 valve road A of four-way reversing valve, after
User terminal water source heat exchanger 3 is flowed through by valve road B and carries out heat release, produces hot water needed for user, now user terminal water source heat exchanger 3
For condenser；Afterwards, refrigerant flow direction is divided into two, and respectively enters electric expansion valve 4a and electric expansion valve 4b and carries out bivalve section
Stream；Cold-producing medium stream after electric expansion valve 4a throttlings is absorbed heat through source air source heat exchanger 5, now source air-source
Heat exchanger 5 is air-source evaporator；By electric expansion valve 4b throttling after refrigerant with by air source heat exchanger 5 heat absorption after
Refrigerant merge together, flow into source water source heat exchanger 6 and absorbed heat, now source water source heat exchanger 6 is water source evaporation
Device；The air entry that compressor 1 is returned to after gas-liquid separator 7 is flowed through afterwards, completes heating working medium circulation.Due to electric expansion valve 4a
It is adjustable with 4b apertures, therefore, flow through source air source heat exchanger 5 and flow through source water source heat exchanger 6 refrigerant flow it is adjustable,
So that the new unit can automatically adjust according to origin of heat difference flows through the refrigerant flow of different evaporators, enter
And making the new unit heat absorption fully, adaptive capacity to environment is stronger, and Energy Efficiency Ratio is higher.
During refrigeration, four-way reversing valve 2 is powered off, and now, the valve road A and valve road D of four-way reversing valve are communicated；Valve road B and valve road C
Communicate.Refrigerant is discharged by the exhaust outlet of compressor 1 after the compression of compressor 1, flows through 2 valve road A of four-way reversing valve, after
Source water source heat exchanger is flowed through by valve road D and carries out heat release, and now source water source heat exchanger 6 is condenser；Afterwards, cold-producing medium stream
To being divided into two, the one end for respectively enteing electric expansion valve 4b is throttled and carries out heat release into source air source heat exchanger 5,
Now source air source heat exchanger 5 is condenser；Flow through the refrigerant after the heat release of source air source heat exchanger 5 and flow into electronic expansion
Valve 4a throttled after and flow through electronic expansion 4b throttling after refrigerant merge together, flow to user terminal water source heat exchanger 3
Absorbed heat, produce the cold water needed for user, now user terminal water source heat exchanger 3 is evaporator；Refrigerant is changed by four-way afterwards
Valve road C is flowed to after to the valve road B of valve 2, the air entry of compressor is finally flowed back to after gas-liquid separator 7, completes refrigeration working medium
Circulation.Because electric expansion valve 4a and 4b aperture is adjustable so that flow through the big I of refrigerant flow of source air source heat exchanger 5
Adjust, so that the new unit can be according to the different autonomous adjusting refrigerant flow rates of environmental factor, and then make the new unit
Heat release is abundant, and adaptive capacity to environment is stronger, and Energy Efficiency Ratio is higher.
