Embodiment 1
[0057] Such as figure 1 As shown, the present invention includes a refrigeration unit 1 , a terminal device 3 and a first chilled water pump 2 , and the first chilled water pump 2 , the evaporator 1 - 2 of the refrigeration unit 1 and the terminal device 3 are sequentially connected in a loop through a first pipeline 4 .
[0058] The third pipeline 5 is bypassed on the first pipeline 4 between the terminal device 3 and the first chilled water pump 2, and the second chilled water pump 6 and the thermal fluid channel 7-1 of the heat exchange device 7 are connected in series on the third pipeline 5 , the other end of the third pipeline 5 is bypassed on the first pipeline 4 between the terminal device 3 and the evaporator 1-2 of the refrigeration unit 1 .
[0059] The cold fluid channel 7-2 of the heat exchange device 7, the evaporator 8-1 of the ice making unit 8, and the ice storage device 9 are connected in a loop through the second pipeline 10, and the cold fluid channel 7-2 o...
Embodiment 2
[0098] Such as figure 2 As shown, other connection methods are the same as Example 1, except that the fifth valve 20 and the sixth valve 16 in Example 1 are combined into a three-way valve 20, and the three-way valve 20 is connected in series between the second pipeline 10 and the sixth pipeline. 19 at the intersection.
Embodiment 3
[0100] Such as image 3 As shown, other connection methods are the same as Example 1. In addition, another brine pump 21 is set on the second pipeline 10 connected to the input end of the cold fluid channel 7-2 of the heat exchange device 7, and the brine pump 21 can be changed to Flow type refrigerant pump.
