Embodiment 1

[0063] Such as figure 1 As shown, the present invention is provided with a refrigerating unit 1, a terminal device 3, a first chilled water pump 2, and the first chilled water pump 2, the evaporator 1-2 of the refrigerating unit 1, and the terminal device 3 are sequentially connected in a loop through a first pipeline 4.

[0064] The second 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 second pipeline 5 , the other end of the second pipeline 5 is bypassed on the first pipeline 4 between the terminal device 3 and the evaporator 1-2 of the refrigeration unit 1 .

[0065] The cold fluid channel 7 - 2 of the heat exchange device 7 , the (variable flow) ice-melting brine pump 8 , the ice storage device 9 and the first valve 10 are connected in a loop through a fourth pipeline 11 . The f...

Embodiment 2

[0101] Such as figure 2 As shown, the others are the same as in Embodiment 1, but the ice-melting brine pump 8 is a common brine pump, and in addition, it is connected between the fourth pipeline 11 at the two ends of the cold fluid channel 7-2 connecting the heat exchange device 7 The sixth pipeline 20, the fifth valve 21 is connected in series on the pipeline 20. A sixth valve 22 is connected in series on the fourth pipeline 11 between the pipeline 20 and both ends of the cold fluid channel 7 - 2 of the heat exchange device 7 .

[0102] Through the fifth valve 21 and the sixth valve 22 , the flow rate of brine entering the cold fluid channel 7 - 2 of the heat exchange device 7 is adjusted to adjust the temperature of the chilled water in the hot fluid channel 7 - 1 of the heat exchange device 7 .

Embodiment 3

[0104] Such as image 3 As shown, other connection methods are the same as Example 2, except that the fifth valve 21 and the sixth valve 22 in Example 2 are combined into a three-way valve 21, and the three-way valve 21 is connected to the fourth pipeline 11 and the sixth pipeline 20 the intersection.

Abstract

The invention discloses a parallel ice cold accumulation refrigerating system and a refrigerating method thereof, and relates to the technical field of refrigerating air conditioners, wherein the parallel ice cold accumulation refrigerating system comprises a refrigerating unit set, a terminal device, an ice maker set, a heat exchange device and an ice accumulation device; an evaporator of the ice maker set and the ice accumulation device as well as a cold fluid channel in the heat-exchanging device are mutually connected in parallel; a hot fluid channel in the heat exchange device is connected with the terminal device through a pipeline in a loop mode; the pipeline is arranged between a condenser of the ice maker set and the evaporator of the refrigerating unit set in a loop mode; the pipeline is provided with a circulating pump and a control valve correspondingly; and cooling water of the condenser of the ice maker set is supplied by the refrigerating unit set through precooling to 2-20 DEC C. According to the invention, the problems that a conventional refrigerating unit set can not operate under the ice making working condition, the dual-working-condition refrigerating unit set under the ice making working condition is great in compression rate, high in cost and complex to control, and the like are overcome, the cost of a refrigerating system can be lowered, and the ice making efficiency and the operation stability are improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to the technical field of refrigeration and air conditioning. Background technique [0002] Conventional refrigeration systems are generally composed of refrigeration equipment, cold source devices, terminal devices, auxiliary equipment, connecting pipelines, and control systems. The most widely used refrigeration equipment is a vapor compression refrigeration unit, which consists of an evaporator, a compressor, a condenser, and a throttling device connected through copper pipes to form a closed circuit, and the circuit is filled with refrigerant. When the refrigeration unit is working, the refrigerant circulates in the evaporator, compressor, condenser, and throttling device to perform four processes of evaporation, compression, condensation, and throttling, and transfers heat from the evaporator to the condenser. [0003] In a typical refrigeration system, the refrigerating...
