In this way, the stream by controlling the correlative flow regulating member and the first control valve 91 that adjust outer machine heat-exchange unit 1
The modes such as amount aperture will flow through the cold of heating heat-exchange unit 33 based on the real-time cold medium flux that second flow sensor detects
Matchmaker's flow control is in heating target cold medium flux h3, to be adapted with current operating mode.
When controller receive be used to indicate multi-connected machine water chiller-heater unit operational mode be heat heating double mode control
When system instruction, the rotation of controller controlled motion valve block switches to heating valve position, opens break-make solenoid valve 8,91 and of the first control valve
Second control valve 92.
As shown in figure 4, at this point, refrigerant flow of the multi-connected machine water chiller-heater unit in the case where heating heating pattern be two, wherein
The refrigerant of one refrigerant flow flows to：1 → refrigerant of outer machine heat-exchange unit goes out pipeline (outer machine heat-exchange unit 1) → b port → the
One ports 61 → a of sub-chamber → refrigerant goes out pipeline (interior machine heat-exchange unit into pipeline (interior machine heat-exchange unit 2) → indoor unit → refrigerant
2) → ports the f → ports 63 → g of third sub-chamber → 7 → refrigerant of external pipeline is changed into pipeline (outer machine heat-exchange unit 1) → outer machine
Heat engine group 1；The refrigerant of an other refrigerant flow flows to：1 → refrigerant of outer machine heat-exchange unit goes out pipeline (outer machine heat-exchange unit 1)
The ports 61 → c of sub-chamber of ports → b → first → refrigerant goes out pipeline and (adopts into pipeline (heating heat-exchange unit 33) → floor heating → refrigerant
Warm heat-exchange unit 33) ports 62 → e of sub-chamber of → ports d → second → refrigerant changes into pipeline (outer machine heat-exchange unit 1) → outer machine
Heat engine group 1.
At this point, outer machine heat-exchange unit 1, which is produced, and to be delivered to heating respectively via above-mentioned refrigerant flow direction and changes for high temperature refrigerant
Heat engine group 33 and interior machine heat-exchange unit 2.This is the refrigerant circulation flow path heated under heating pattern.
Here, controller is additionally operable to go out liquid temperature according to interior machine feed liquor temperature and interior machine, interior machine heat-exchange unit is calculated
2 interior machine target cold medium flux；And liquid temperature is gone out according to heating feed liquor temperature and heating, heating heat-exchange unit 33 is calculated
Heating target cold medium flux.
For example, interior machine feed liquor temperature is T41, it is T42 that interior machine, which goes out liquid temperature, and heating feed liquor temperature is T43, and heating goes out liquid temperature
Degree is T44, sets the ability of outer machine heat-exchange unit 1 as Q, metered flow H=Q*0.143；The temperature difference of machine liquid in-out in calculating
T41=T42-T41, the temperature difference T42=T44-T43 of heating liquid in-out；
Heating target cold medium flux h41 can then be calculated according to following formula：
Heating target cold medium flux h41 is calculated according to following formula：
In this way, adjusting the correlative flow regulating member and the first control valve 91, second of outer machine heat-exchange unit 1 by controlling
The modes such as the flow aperture of control valve 92 will be flowed through interior based on the real-time cold medium flux that the first, second flow sensor detects
The cold medium flux control of machine heat-exchange unit 2 flows through the cold medium flux control of heating heat-exchange unit 33 in heating target cold medium flux h41
System is in heating target cold medium flux h42, to be adapted with current operating mode.
