Example Embodiment

[0090] Example 1

[0091] This embodiment provides a refrigeration cycle system. figure 1 A structural diagram of a refrigeration cycle system according to a first embodiment of the present invention, such as figure 1 As shown, the refrigeration cycle system includes: the first heat exchanger 1, the water side of the first heat exchanger 1 communicates with the refrigerated water inlet and the frozen water outlet, so that the water is fed out by the frozen water outlet after the water enters the water inlet. Also included including the first line of communication between the outlet end of the first heat exchanger 1 and the inlet end of the second heat exchanger 2, a liquid pump 3 is provided on the first conduit 3; the outlet end of the first heat exchanger 1 There is also a second conduit between the inlet end of the second heat exchanger 2, and the first end A and the second end B of the second conduit are connected to the first line, and the first end A and the second end. B is...

Example Embodiment

[0096] Example 2

[0097] This embodiment provides another refrigeration cycle system. figure 2 A structural diagram of the refrigeration cycle system according to the second embodiment of the present invention, in order to achieve the flow direction control of the heat exchange medium, such as figure 2 As shown, the system also includes: the first valve 6, disposed on the first conduit, between the first end A of the liquid pump 3 and the second conduit, and is used to control the heat transfer medium inflow liquid pump. 3, when the system is energized, the first valve 6 is turned on, so that the heat transfer medium flows into the liquid pump 3. When the system is powered off, the first valve 6 is closed, thereby so that the heat exchange medium does not flow into the liquid pump 3.

[0098] The second valve 7 is also included in the second valve 7, which is configured to control whether the second line is turned on, ie whether the heat transfer medium flows into the second line...

Abstract

The invention discloses a refrigeration cycle system and a control method thereof. Wherein, the system comprises a first pipeline which is for communication between a first heat exchanger and a secondheat exchanger and is provided with a liquid pump; a second pipeline of which the first end and the second end both communicate with the first pipeline and are located on the two sides of the liquidpump; a high-pressure gas storage tank which is arranged on the second pipeline and is used for exhausting high-pressure gas to drive a heat exchange medium to circulate; and a liquid storage tank which is arranged on the first pipeline, located at the downstream of the second end of the second pipeline and used for storing the heat exchange medium. By the refrigeration cycle system disclosed by the invention, uninterrupted refrigeration during power failure can be realized, and safe operation of equipment in the database is guaranteed.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration cycle system and a control method thereof. Background technique [0002] The chiller used in the data center is characterized by year-round cooling. At present, when the outdoor temperature is low (such as winter in severe cold areas), the natural cooling scheme can be used to effectively use the outdoor cold source for cooling, which improves the annual cooling height of the data center. However, when the unit is using natural cooling, if a power outage occurs for a long time, it will lead to cooling interruption, which cannot guarantee the safe and reliable operation of various equipment in the data center. [0003] Aiming at the problem of refrigeration interruption caused by power failure for a long time when natural cooling is adopted in the prior art, no effective solution has been proposed so far. Contents of the invention [0004] Embodiments of t...
