The second heat exchange loop that defrosting side heat-exchanger rig is constituted, to carry out defrosting to heat source tower heat-exchanger rig input heat.
When the wind pressure of multiple heat source tower heat-exchanger rigs meets defrosting condition, then it can exchange heat and fill to multiple heat source tower simultaneously
Carry out defrosting is set, or defrosting successively is carried out to multiple heat source tower heat-exchanger rig.For example, when needing to exchange heat to 2 heat source towers
When device successively carries out defrosting, as shown in figure 11, into after defrosting process, defrosting side total switchgear is opened, close the first heat
Then the blower of source tower is sequentially connected the second heat exchange loop of the first heat source tower, disconnects the first heat exchange of the first heat source tower
Defrosting water pump is restarted in circuit, and defrosting side heat-exchanger rig inputs heat to the first heat source tower heat-exchanger rig at this time, to the first heat source
Tower heat-exchanger rig carries out defrosting.After defrosting time t, the defrosting process to the first heat source tower heat-exchanger rig, starting pair are completed
The defrosting process of Secondary Heat Source tower heat-exchanger rig, specifically: the blower of Secondary Heat Source tower is closed, Secondary Heat Source tower is then connected
Second heat exchange loop disconnects the first heat exchange loop of Secondary Heat Source tower, at this point, defrosting side heat-exchanger rig is to Secondary Heat Source tower
Heat-exchanger rig inputs heat, carries out defrosting to Secondary Heat Source tower heat-exchanger rig.Meanwhile connecting the first heat exchange of the first heat source tower
Circuit, and the second heat exchange loop of the first heat source tower is disconnected, start the blower of the first heat source tower, so that the first heat source tower restores
Normal heat exchange carries out heat exchange with heat source tower side heat source heat-exchanger rig.After defrosting time t, complete to Secondary Heat Source
The defrosting process of tower heat-exchanger rig then closes defrosting water pump, disconnects the second heat exchange loop of Secondary Heat Source tower, closes defrosting side
Total switchgear, and the first heat exchange loop of Secondary Heat Source tower is connected, start the blower of Secondary Heat Source tower, so that Secondary Heat Source
Tower restores normal heat exchange, i.e., carries out heat exchange with heat source tower side heat source heat-exchanger rig.
When there is a heat source tower heat-exchanger rig not need defrosting in multiple heat source towers, to other heat source tower heat-exchanger rigs
When carrying out defrosting, without closing heat source tower heat source side heat pump unit, it will not influence using side water temperature, it is full to promote user experience
Meaning degree.
