A large amount of energy is consumed, and in severe cases, the equipment will shut down due to overheating.
[0003] With the large-scale use of air-cooled row-to-row air conditioners in data centers, the energy efficiency requirements are increasing year by year. With the development of conventional air-cooled row-to-row air conditioner technology, the energy efficiency of the compressor system has reached its limit. The solution of using fluorine pumps with higher energy efficiency under low-temperature conditions to replace compressors operating under low-temperature conditions is gradually developing.
[0004] At present, most data centers use two systems designed separately for cooling, namely, the fluorine pump and the compressor. The fluorine pump system is used in winter when the temperature is low, and the compressor system is used at other times, which achieves a certain energy saving purpose. However, the fluorine pump and the compressor are separated, which requires the formation of two different refrigeration circuits, increasing the volume of the overall equipment, occupying a large space, and increasing energy consumption. Summary of the invention
[0005] Based on this, it is necessary to provide a refrigeration device and a data center, which can integrate the fluorine pump and the compressor into a system, reduce the size of the refrigeration device, thereby reducing the space occupied by the refrigeration device, and at the same time enable the refrigeration device to have a higher energy efficiency ratio to reduce the energy consumption of the compressor.

[0014] In one embodiment of the present application, the pipeline assembly also includes an oil return pipeline, and the refrigeration device also includes an oil separator, a filter and an oil return capillary. The oil separator is arranged at the connection between the second pipeline and the oil return pipeline. The oil return pipeline is connected to the second pipeline and is connected in parallel with the compressor.

[0017] After adopting the above technical solution, this application has at least the following technical effects:
[0018] The refrigeration device and data center of the present application, in which the first pipeline and the second pipeline are arranged in parallel, and the two ends of the parallel connection are connected to the two ends of the main pipeline to form a circuit of the refrigeration device. The condenser, the fluorine pump, the electronic expansion valve and the evaporator are arranged at intervals along the flow direction of the refrigerant, and the compressor is arranged in the second pipeline. When the compressor is operated alone, the refrigerant in the evaporator enters the compressor through the second pipeline, and then the refrigerant returns to the evaporator through the main pipeline, the condenser and the fluorine pump. When the fluorine pump is operated alone, the refrigerant in the evaporator enters the fluorine pump through the first pipeline and the condenser, and returns to the evaporator through the fluorine pump.
[0019] The refrigeration device can set the fluorine pump and the compressor in the same system. Under low temperature conditions, the compressor is turned off and the fluorine pump is turned on. The refrigerant is transported through the fluorine pump, so that the high-pressure liquid refrigerant output by the condenser enters the evaporator through the fluorine pump. Under high temperature conditions, the compressor is running and the fluorine pump is turned off. At this time, the compressor compresses the refrigerant in the normal temperature gas state into high-pressure gas so that the gas is transported to the condenser. Moreover, the fluorine pump and the compressor can also run at the same time to meet the refrigerant transportation needs. The fluorine pump and the compressor realize the circulation of the refrigerant through a system, so that the refrigeration device can cool the various data modules of the data center at different ambient temperatures, without the need to use two circulation systems, reducing the number of parts and thus reducing the volume of the refrigeration device, so as to reduce the space occupied by the refrigeration device, and at the same time, it can also make the refrigeration device have a higher energy efficiency ratio to reduce the energy consumption of the compressor.

[0030] See also Figures 1 to 3 The present application provides a refrigeration device 10. The refrigeration device 10 is applied in a data center to cool each data module in the data center to reduce the temperature of each data module and ensure the reliability of the data center. Figure 1 This is a schematic diagram of a liquid cooling device according to an embodiment of the present application. Figure 2 for Figure 1 The enlarged view of the liquid cooling device at A is shown. Figure 3 for Figure 1 The liquid cooling device is shown as a partial enlarged view at B. This application only uses the refrigeration device 10 applied to a data center as an example for explanation. Of course, in other embodiments of the application, the refrigeration device 10 can also cool other equipment.
[0031] It is understandable that currently data centers mostly use two systems designed separately for cooling, namely, a fluorine pump and a compressor. The fluorine pump system is used when the temperature is low in winter, and the compressor system is used at other times, thereby achieving a certain energy-saving purpose. However, the way in which the fluorine pump and the compressor are separated requires the formation of two different refrigeration circuits, which increases the volume of the overall equipment, occupies a large space, and increases energy consumption. To this end, the present application provides a novel refrigeration device 10, which can reduce the volume of the refrigeration device 10 to reduce the space occupied by the refrigeration device 10, and at the same time can also make the refrigeration device 10 have a higher energy efficiency ratio to reduce the energy consumption of the compressor 110. The specific structure of the refrigeration device 10 of an embodiment is introduced below.
[0032] See also Figures 1 to 3In one embodiment, the refrigeration device 10 includes a compressor 110, a condenser 120, a fluorine pump 130, an evaporator 140 and a pipeline assembly 150, wherein the pipeline assembly 150 includes a main pipeline 151, a first pipeline 152 and a second pipeline 153; the condenser 120, the fluorine pump 130 and the evaporator 140 are arranged in the main pipeline 151 at intervals along the flow direction of the refrigerant, the first pipeline 152 and the second pipeline 153 are arranged in parallel, and their two ends are connected to the two ends of the main pipeline 151 to form a loop, and the compressor 110 is arranged in the second pipeline 153. The liquid cooling device also includes an electronic expansion valve 160, which is arranged in the main pipeline 151 and located between the fluorine pump 130 and the evaporator 140.
[0033] The pipeline assembly 150 connects various components of the refrigeration device 10 to realize the circulation and transportation of the refrigerant. The pipeline assembly 150 includes a main pipeline 151, a first pipeline 152 and a second pipeline 153. The main pipeline 151 has a first end 1511 and a second end 1512 arranged opposite to each other, and the main pipeline 151 is arranged in a disconnected manner. The first pipeline 152 and the second pipeline 153 are arranged in parallel, and one end of the first pipeline 152 and the second pipeline 153 are simultaneously connected to the first end 1511 of the main pipeline 151, and the other end of the first pipeline 152 and the second pipeline 153 are connected to the second end 1512 of the main pipeline 151. In this way, the refrigerant in the main pipeline 151 enters the first pipeline 152 through the first end 1511, and then returns to the main pipeline 151 through the second end 1512; similarly, the refrigerant in the main pipeline 151 enters the second pipeline 153 through the second end 1512, and then returns to the main pipeline 151 through the second end 1512.
[0034] The compressor 110 is arranged in the second pipeline 153, and the condenser 120, the fluorine pump 130 and the evaporator 140 are arranged in the main pipeline 151 at intervals, and the condenser 120, the fluorine pump 130 and the evaporator 140 are arranged in sequence along the flow direction of the refrigerant. The flow direction of the refrigerant refers to the direction in which the refrigerant flows out from the first end 1511 of the main pipeline 151, passes through the first pipeline 152 or the second pipeline 153, and enters the main pipeline 151 through the second end 1512. In other words, the refrigerant flows counterclockwise, such as Figure 1 The refrigerant flows in the direction of the arrow.
[0035] In order to better illustrate the arrangement positions of the components in the refrigeration device 10, an input end and an output end are introduced here. The input end and the output end are based on the flow of the refrigerant. The direction in which the refrigerant flows into the component is the input direction, and the direction in which the refrigerant flows out is the output direction. The condenser 120 is located in the output direction of the compressor 110, the fluorine pump 130 is located in the output direction of the condenser 120, the electronic expansion valve 160 is located in the output direction of the fluorine pump 130, and the evaporator 140 is located in the output direction of the electronic expansion valve 160. That is, the fluorine pump 130 is located between the electronic expansion valve 160 and the condenser 120, the electronic expansion valve 160 is located between the fluorine pump 130 and the evaporator 140, the evaporator 140 is located between the electronic expansion valve 160 and the compressor 110, the compressor 110 is located between the evaporator 140 and the condenser 120, and the condenser 120 is located between the fluorine pump 130 and the compressor 110.
[0036] The refrigerant can flow through the evaporator 140, the compressor 110, the condenser 120, and the electronic expansion valve 160. The evaporator 140 outputs a normal temperature gaseous refrigerant, the compressor 110 outputs a high pressure gaseous refrigerant, the condenser 120 outputs a high pressure medium temperature liquid refrigerant, and the electronic expansion valve 160 outputs a low temperature low pressure liquid refrigerant. The fluorine pump 130 is a power pump. The fluorine pump 130 is arranged behind the condenser 120. The fluorine pump 130 can provide power for the high pressure liquid refrigerant to realize the circulation of the refrigerant. The second pipeline 153 where the compressor 110 is located is arranged in parallel with the first pipeline 152. The refrigerant in the main pipeline 151 can flow through the first pipeline 152 or the second pipeline 153 through the compressor 110 back to the main pipeline 151.
[0037] Under low temperature conditions, the compressor 110 is stopped, the fluorine pump 130 is running, and the refrigerant does not enter the main line 151 through the second pipeline 153. At this time, the refrigerant output by the evaporator 140 enters the condenser 120 through the first pipeline 152. After the condenser 120 condenses the refrigerant, the refrigerant passes through the fluorine pump 130 through the main line 151 and the electronic expansion valve 160 and enters the evaporator 140. Under high temperature conditions, the fluorine pump 130 is stopped, the compressor 110 is running, and the refrigerant does not enter the main line 151 through the first pipeline 152. At this time, the refrigerant output by the evaporator 140 enters the compressor 110 through the second pipeline 153. After being compressed by the compressor 110, it enters the condenser 120 through the main line 151. After the condenser 120 condenses the refrigerant, the refrigerant passes through the fluorine pump 130 through the main line 151 and the electronic expansion valve 160 and enters the evaporator 140. Under medium temperature conditions, the fluorine pump 130 and the compressor 110 are both turned on. Turning on the fluorine pump 130 increases the pressure before the electronic expansion valve 160, so that the compressor 110 can save power consumption and reduce the condensing pressure.
[0038] Exemplarily, the low temperature condition refers to an ambient temperature below 5°C. Under the low temperature condition, the compressor 110 will have a large power consumption when running. At the same time, the compressor 110 has a low temperature. Therefore, when the fluorine pump 130 is running, the refrigerant can be directly delivered to the evaporator 140 through the first pipeline 152 and the electronic expansion valve 160 to realize the refrigeration function of the refrigerant. The high temperature condition refers to an ambient temperature above 35°C. Under the high temperature condition, the compressor 110 is running and the fluorine pump 130 is turned off. At this time, the compressor 110 directly compresses the refrigerant. Moreover, after the fluorine pump 130 is turned off, the refrigerant can pass through the main pipeline 151 where the fluorine pump 130 is located and then enter the evaporator 140 through the electronic expansion valve 160.
[0039] Medium temperature conditions refer to an ambient temperature between 5°C and 35°C. The ambient temperature under medium temperature conditions can reduce the condensing pressure to reduce the power consumption of the compressor 110, but the lower pressure before the electronic expansion valve 160 will lead to a reduced throttling effect and a reduced cooling capacity. Therefore, under medium temperature conditions, the compressor 110 and the fluorine pump 130 are operated simultaneously, and the fluorine pump 130 is used to pressurize the refrigerant at the outlet of the condenser 120 to increase the liquid pressure before the valve. Of course, in other embodiments of the present application, the ambient temperature referred to in the low temperature condition, the medium temperature condition, and the high temperature condition may also be other.
[0040] The refrigeration device 10 of the above-mentioned embodiment can set the fluorine pump 130 and the compressor 110 in the same system to realize the circulation and transportation of the refrigerant, so that the refrigeration device 10 can cool the various data modules of the data center at different ambient temperatures without using two sets of circulation systems, thereby reducing the number of parts and thus reducing the volume of the refrigeration device 10, so as to reduce the occupied space of the refrigeration device 10, and at the same time, the refrigeration device 10 can have a higher energy efficiency ratio to reduce the energy consumption of the compressor 110.
[0041] Optionally, the compressor 110 uses a compressor 110 with a low compression ratio to avoid a malfunction of the compressor 110 due to an excessively low condensing pressure. Optionally, a fan is provided at a position corresponding to the condenser 120 and the evaporator 140, and the temperature is reduced by the fan. Optionally, the refrigeration device 10 further includes a plurality of pressure sensors and a plurality of temperature sensors, which are arranged at intervals in the main pipeline 151 and the second pipeline 153, the pressure sensor detects the pressure of the refrigerant, and the temperature sensor detects the temperature of the refrigerant.
[0042] Optionally, the refrigeration device 10 further includes a high-pressure switch and a low-pressure switch, the high-pressure switch and the low-pressure switch are located in the second pipeline 153, and the high-pressure switch is located at the output end of the compressor 110, and the low-pressure switch is located at the input end of the compressor 110. Optionally, the refrigeration device 10 further includes two drying filters, one of which is arranged at the input end of the fluorine pump 130, and the other drying filter is arranged between the fluorine pump 130 and the electronic expansion valve 160. Optionally, the refrigeration device 10 further includes night vision goggles, which are arranged between the drying filter and the electronic expansion valve 160.
[0043] It is worth noting that, under high temperature conditions, the compressor 110 is running and the fluorine pump 130 is turned off. At this time, the refrigerant passes through the fluorine pump 130 directly into the evaporator 140 through the electronic expansion valve 160. Of course, a bypass line 154 can also be added to transport the refrigerant through the bypass line 154. For details, see Figure 1 and Figure 2 In one embodiment, the main line 151 also includes a bypass line 154, both ends of the bypass line 154 are connected to the main line 151, and the bypass line 154 is arranged in parallel with the fluorine pump 130. In other words, the bypass line 154 is arranged in parallel with the part of the main line 151 where the fluorine pump 130 is located. When the fluorine pump 130 is running, the refrigerant in the main line 151 passes through the fluorine pump 130 and enters the evaporator 140 through the electronic expansion valve 160; when the compressor 110 is running and the fluorine pump 130 is turned off, the refrigerant returns to the main line 151 through the bypass line 154, and then enters the evaporator 140 through the electronic expansion valve 160. At this time, the refrigerant will not pass through the fluorine pump 130, avoiding the high pressure drop after the refrigerant passes through the fluorine pump 130.
[0044] Optionally, the refrigeration device 10 further includes a manual valve 180, which is arranged on the bypass line 154 to control the on-off of the bypass line 154. The manual valve 180 is normally open and is manually operated by an operator. When the fluorine pump 130 is running, the manual valve 180 can be used to close the bypass line 154 so that the refrigerant is transported through the fluorine pump 130. When the fluorine pump 130 is turned off, the manual valve 180 is opened to connect the bypass line 154 to the main line 151, and the refrigerant flows through the bypass line 154. Of course, the refrigerant can also flow through the fluorine pump 130 when the fluorine pump 130 is turned off.
[0045] See also Figure 1 and Figure 2 In one embodiment, the refrigeration device 10 further includes a first one-way valve 170, which is disposed in the bypass line 154. The first one-way valve 170 can be opened only when there is a pressure difference, so that the refrigerant can flow through the bypass line 154, and the refrigerant can be prevented from flowing back. When the fluorine pump 130 is turned off, the refrigerant can make the first one-way valve 170 open to the bypass line 154.
[0046] See also Figure 1 and Figure 2 In one embodiment, the refrigeration device 10 further includes a liquid storage tank 190, which is disposed at the input end of the fluorine pump 130. When the fluorine pump 130 is in operation, the refrigerant charge required is greater than the refrigerant charge required for the compressor 110 to operate, so the liquid storage tank 190 is added to the input end of the fluorine pump 130, and when the compressor 110 is in operation, the liquid storage tank 190 is avoided through the bypass line 154 to prevent excessive refrigerant from entering the main line 151. When the fluorine pump 130 is in operation, the refrigerant is drawn from the liquid storage tank 190 into the main line 151 to replenish the refrigerant amount.
[0047] See also Figure 1 and Figure 3 In one embodiment, the refrigeration device 10 further includes a second one-way valve 210, which is disposed in the first pipeline 152. The second one-way valve 210 can be turned on only when there is a pressure difference. When the compressor 110 is running, the second one-way valve 210 is turned off, and the refrigerant returns to the main pipeline 151 through the compressor 110 via the second pipeline 153. When the compressor 110 is stopped, the second one-way valve 210 is turned on, and the refrigerant returns to the main pipeline 151 via the first pipeline 152.
[0048] See also Figure 1 and Figure 2 In one embodiment, the refrigeration device 10 further includes a third one-way valve 220, which is disposed at the output end of the fluorine pump 130. When the fluorine pump 130 is running, the refrigerant enters the electronic expansion valve 160 through the third one-way valve 220, and the third one-way valve 220 can prevent the refrigerant from returning to the fluorine pump 130.
[0049] See also Figure 1 and Figure 3 In one embodiment, the refrigeration device 10 further includes a solenoid valve 230, which is disposed in the second pipeline 153 and located between the compressor 110 and the evaporator 140. In other words, the solenoid valve 230 is added to the suction side (i.e., the input end) of the compressor 110, and when the compressor 110 is not started, the solenoid valve 230 is closed to prevent the refrigerant from entering the second pipeline 153.
[0050] In one embodiment, the pipeline assembly 150 also includes an oil return pipeline 155, and the refrigeration device 10 also includes an oil separator 250, a filter 260 and an oil return capillary 270. The oil separator 250 is arranged at the connection between the second pipeline 153 and the oil return pipeline 155. The oil return pipeline 155 is connected to the second pipeline 153 and is connected in parallel with the compressor 110. The filter 260 and the oil return capillary 270 are arranged in the oil return pipeline 155, and the filter 260 is located between the oil separator 250 and the oil return capillary 270.
[0051] The refrigerant and the lubricating oil of the compressor 110 are separated by the oil separator 250, and the separated refrigerant returns to the second pipeline 153, and the lubricating oil returns to the compressor 110 through the oil return pipeline 155. The oil return capillary 270 is provided in the oil return pipeline 155, and the lubricating oil is processed by the oil return capillary 270 to ensure the lubrication effect of the compressor 110. A filter 260 is added between the oil separator 250 and the oil return capillary 270 to prevent the oil return capillary from being blocked by debris. Optionally, the filter 260 is a mesh filter 260. Of course, in other embodiments of the present application, the filter 260 can also be other components that can filter debris.
[0052] See also Figure 1 and Figure 3 In one embodiment, the refrigeration device 10 further includes a fourth one-way valve 280, which is disposed in the second pipeline 153 and located at the output end of the oil separator 250 and the compressor 110. In other words, the fourth one-way valve 280 is disposed in the second pipeline 153 near the second end 1512 of the main pipeline 151. Because there is a lot of refrigerant in the main pipeline 151 when the fluorine pump 130 is running, in order to prevent the refrigerant from entering the compressor 110, the fourth one-way valve 280 is added at the output end of the oil separator 250 to prevent backflow.
[0053] See also Figure 1 In one embodiment, the refrigeration device 10 further includes a plurality of needle valves 290, which are arranged at intervals between the main pipeline 151 and the second pipeline 153. The needle valves 290 can be connected to external components to meet the needs of adding refrigerant to the refrigeration device 10, and avoid dead corners when vacuuming and charging refrigerant.
[0054] The refrigeration device 10 of the present application can set the fluorine pump 130 and the compressor 110 in the same system. Under low temperature conditions, the compressor 110 is turned off, the fluorine pump 130 is turned on, and the refrigerant is transported through the fluorine pump 130, so that the high-pressure liquid refrigerant output by the condenser 120 enters the evaporator 140 through the fluorine pump 130. Under high temperature conditions, the compressor 110 is running and the fluorine pump 130 is turned off. At this time, the compressor 110 compresses the refrigerant in the normal temperature gas state into high-pressure gas, so that the gas is transported to the condenser 120. Moreover, the fluorine pump 130 and the compressor 110 can also run at the same time to meet the refrigerant transportation requirements. The fluorine pump 130 and the compressor 110 realize the circulation and transportation of the refrigerant through a system, so that the refrigeration device 10 can cool the various data modules of the data center at different ambient temperatures, without the need to use two circulation systems, thereby reducing the number of parts and thus reducing the volume of the refrigeration device 10, thereby reducing the space occupied by the refrigeration device 10, and at the same time enabling the refrigeration device 10 to have a higher energy efficiency ratio, thereby reducing the energy consumption of the compressor 110.
[0055] The present application also provides a data center, including multiple data modules and a refrigeration device 10 as any of the above technical features, wherein the multiple data modules are arranged at intervals, and a refrigeration device 10 is arranged between adjacent data modules, and the refrigeration device 10 can cool the data modules. After the data center of the present application adopts the refrigeration device 10 of the above embodiment, the cooling effect of the data module can be guaranteed, the energy consumption of the data center during operation can be reduced, and the reliability of the work can be guaranteed.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
