[0038] The present disclosure provides a liquid supply system, such as Figures 1 to 4 As shown, the liquid supply system includes a heat exchanger 1 and a plurality of switch assemblies 2. The heat exchanger 1 includes a first flow passage, a first inlet 11 and a first outlet 12. The first inlet 11 is in communication with the first outlet 12 through the first flow passage. The first inlet 11 is configured to be connected to a water supply source 81. Each of the switch assemblies 2 includes a liquid supply valve 21 and a communication valve 22. The liquid supply valve 21 includes a liquid inlet interface 211, a first liquid outlet interface 212 and a second liquid outlet interface 213.

The second liquid outlet interface 213 is configured to be in communication with or disconnected from the liquid inlet interface 211. The communication valve 22 includes a first communication interface 221 and a second communication interface 222. The first communication interface 221 is configured to be in communication with or disconnected from the second communication interface 222. The first communication interface 221 is connected to the first liquid outlet interface 212. The plurality of switch assemblies 2 are arranged in sequence. The liquid inlet interface 211 of the liquid supply valve 21 in the first switch assembly 2 at a first end is connected to the first outlet 12. For two adjacent switch assemblies 2 in the plurality of switch assemblies 2, the second communication interface 222 of the communication valve 22 in the switch assembly 2 at an upstream side is connected to the liquid inlet interface 211 in the switch assembly 2 at a downstream side.
[0039] When the liquid supply system supplies liquid to the first water using point 85, the second liquid outlet interface 213 of the liquid supply valve 21 in the switching assembly 2 corresponding to the first water using point 85 is in communication with the liquid inlet interface 211, and the first communication interface 221 of the communication valve 22 in the switching assembly 2 corresponding to the first water using point 85 is disconnected from the second communication interface 222. At this time, the water flowing out of the water supply source 81 can flow to the liquid inlet interface 211 of the liquid supply valve 21 in the switching assembly 2 corresponding to the first water using point 85 after being heat-exchanged in the heat exchanger 1, and then flow to the first water using point 85 through the second liquid outlet interface 213. When the liquid supply system supplies liquid to the water using points 85 other than the first water using point 85, the first communication interface 221 of the communication valve 22 in the switching assembly 2 corresponding to the water using point 85 located on the upstream side of the water using point 85 is in communication with the second communication interface 222, the second liquid outlet interface 213 of the liquid supply valve 21 in the switching assembly 2 corresponding to the water using point 85 located on the upstream side of the water using point 85 is disconnected from the liquid inlet interface 211, the second liquid outlet interface 213 of the liquid supply valve 21 in the switching assembly 2 corresponding to the water using point 85 is in communication with the liquid inlet interface 211, and the first communication interface 221 of the communication valve 22 in the switching assembly 2 corresponding to the water using point 85 is disconnected from the second communication interface 222. At this time, the water flowing out of the water supply source 81 can flow to the liquid inlet interface 211 of the liquid supply valve 21 in the switching assembly 2 corresponding to the water using point 85 after being heat-exchanged in the heat exchanger 1, and then flow to the water using point 85 through the second liquid outlet interface 213. In this way, the liquid supply system can supply water to multiple water using points 85 through the cooperation of multiple switching assemblies 2 and one heat exchanger 1, the number of heat exchangers 1 is reduced, and the pipeline for connecting the heat exchanger 1 and the chilled water source 84 is also reduced, thereby reducing the cost of the liquid supply system.

The second connecting pipeline 32 comprises two disconnected sections. One section connects the proportional valve 41 with the second outlet 14, and the other section connects the proportional valve 41 with the chilled water source 84. By adjusting the opening degree of the proportional valve 41, the flow rate of the chilled water entering the second heat exchange flow channel can be adjusted, so as to adjust the water temperature of the water supplied to the water using points 85.
[0047] Further, the first connecting pipeline 31 is provided with a heat exchange valve 42.

One end of the first installation pipe 91 is used for being connected with the steam source 82, and the other end of the first installation pipe 91 is connected with the first inlet 11. The first switch valve 71 is arranged on the first installation pipe 91. After the water supply is completed, the switching valve 44 is closed, so that the water no longer enters the fourth connecting pipe 34. Then the first switch valve 71 can be opened, so that the steam enters the heat exchanger 1 and flows to the first connecting pipe 51, so as to achieve the sterilization effect.
