The inventor notes that if the data center fails to operate properly, the data center will cause great harm to users. Therefore, it is important to ensure the normal operation of the data center, and whether the data center can normally operate is critical to whether the water cooling system can normally operate. The water cooling system has a plurality of devices and complex parameters, and maintenance personnel can hardly monitor all operating parameters at the same time, so that the monitoring of the water cooling system is difficult.
Fig. 1-4 are schematic block diagrams of water cooling systems according to various embodiments of the present disclosure.
Fig. 1 to 4 show 4 architectures of water cooling systems. Wherein, fig. 1 is a primary pump and ring network tower system, fig. 2 is a primary pump and one-to-one tower system, fig. 3 is a secondary pump and ring network tower system, and fig. 4 is a secondary pump and one-to-one tower system.
As shown in fig. 1 and 3, the water cooling system is a ring network tower system. The looped network tower system may include one or more sets of cooling tower components, a cooling water loop, and one or more sets of heat exchange assemblies, the cooling water loop being connected between the one or more sets of cooling tower components and the one or more sets of heat exchange assemblies. Fig. 1 and 3 exemplarily illustrate a case where the water cooling system includes 3 sets of cooling tower parts and 3 sets of heat exchange assemblies, it should be understood that the respective numbers of the cooling tower parts and the heat exchange assemblies in the water cooling system may be set as desired. Each set of cooling tower components may include one or more cooling tower members, with fig. 1 and 3 exemplarily showing a case where each set of cooling tower components includes 2 cooling tower members. It should be appreciated that the number of cooling tower components included in each set of cooling tower components may be set as desired. Each set of heat exchange assemblies may include a plurality of cooling water pump components, chiller components, heat exchangers, and chilled water pump components, the construction of which and the calculation of their availability will be further described in connection with some embodiments.
In fig. 2 and 4, the water cooling system is a one-to-one tower system. The one-to-one tower system may include one or more sets of water cooling paths, each set of water cooling paths including a set of cooling tower components and a set of heat exchange assemblies. The cooling tower components and heat exchange assemblies may be as described above.
In fig. 3 and 4, a secondary pump assembly is also included at the end of the water cooling system, the secondary pump assembly being connected to the rear end of each set of heat exchange assemblies in the water cooling system.
Fig. 5 is a flow chart of a method of determining availability of a water cooling system according to some embodiments of the present disclosure, which may include step S510 and step S520 as described below. Methods of determining availability of a water cooling system according to some embodiments of the present disclosure are described below in conjunction with fig. 1-5.
In step S510, in response to the water cooling system being a looped network tower system, calculating availability of each of the one or more sets of cooling tower components, cooling water loop, and one or more sets of heat exchange components, the availability of the water cooling system being calculated based on the availability of each of the one or more sets of cooling tower components, cooling water loop, and one or more sets of heat exchange components; alternatively, in response to the water cooling system being a one-to-one tower system, the availability of each of the cooling tower components and the heat exchange assembly is calculated, the availability of each set of water cooling paths is calculated based on the availability of each set of water cooling paths.
It should be understood that the availability of a device or system refers to the extent to which a device or system is put into operation for a certain period of time without problems, and is a measure of the actual performance of the device or system after it is put into operation. The higher the availability, the higher the security level representing the device or system, the higher the reliability level, the higher the health level. How to calculate the availability of the cooling tower components, cooling water loops, heat exchange assemblies, etc. will be described in detail later in connection with some embodiments.
In step S520, in response to the availability of the water cooling system being less than the set threshold, a reminder message is generated. For example, in response to the availability of the water cooling system being less than a set threshold, an alarm may be sounded and/or a numerical value of the availability may be presented to maintenance personnel of the data center for the maintenance personnel to take corresponding maintenance operations.
In the above embodiment, according to different architectures of the water cooling system, different calculation modes are adopted to calculate the availability of the water cooling system, so that the availability of the obtained water cooling system is more accurate. In addition, the availability can intuitively reflect the health degree of the current water cooling system, and the water cooling system can be reminded to provide a reference index for evaluating the health degree of the water cooling system for maintenance staff under the condition that the availability is smaller than a threshold value, so that the maintenance staff can better manage the water cooling system, and the water cooling system can be ensured to normally run; and the system architecture of the water cooling system is optimized by maintenance personnel according to the availability of the water cooling system, so that the performance of the water cooling system is improved.
Further, the key to the usability of data centers is the ability to ensure proper operation of the systems, and in particular, to ensure uninterrupted and continuous use of the systems. Because the water cooling system is critical to the data center, the normal operation of the water cooling system is ensured by researching the availability of the water cooling system, the downtime of the data center is reduced, the loss of a user is reduced to the greatest extent, and theoretical references are provided for the aspects of how to reduce the use cost of the data center by the user, and the like.
The construction of the heat exchange assembly and its availability calculation is described below in connection with fig. 2-5.
In some embodiments, the water cooling system may have different modes of operation, and the heat exchange assemblies in the water cooling system may have different configurations. The operation modes are, for example, a free cooling mode, a cooling mode, and a precooling mode. In the free cooling mode, the chiller component does not operate; in the precooling mode, the heat exchanger does not operate; in the refrigeration mode, both the chiller component and the heat exchanger are running. It will be appreciated that switching of the water cooling system between the different modes of operation may be achieved by opening and closing the valves shown in figure 1.
In response to the water cooling system being in a free cooling mode, a set of heat exchange assemblies includes a cooling water pump component, a heat exchanger, and a chilled water pump component. In this case, calculating the availability of the set of heat exchange assemblies in the free cooling mode includes calculating the availability of each of the cooling water pump assembly, the heat exchanger, and the chilled water pump assembly; availability A of a set of heat exchange assemblies in a free cooling mode is calculated based on the availability of each of the cooling water pump assembly, the heat exchanger and the chilled water pump assembly free-cooling . For example, the usability of the cooling water pump component is A 1 The usability of the heat exchanger is A 2 Availability of chilled Water Pump part is A 3 If the cooling water pump component, the heat exchanger and the chilled water pump component are connected in series, the availability A of a set of heat exchange components in free cooling mode free-cooling ＝A 1 *A 2 *A 3 . It should be understood that if the cooling water pump component, the heat exchanger, and the chilled water pump component are connected in parallel or otherwise, other calculation formulas may be determined according to the specific connection mode. How to calculate the availability of each of the cooling water pump unit, the heat exchanger and the chilled water pump unit will be further described below in connection with some embodiments.
In response to the water cooling system being in a cooling mode, a set of heat exchange assemblies includes a cooling water pump component, a chiller component, and a chilled water pump component. This is the case Calculating the availability of a set of heat exchange components in a refrigeration mode comprises calculating the availability of each of a cooling water pump component, a water chilling unit component and a chilled water pump component; the availability of a set of heat exchange assemblies in a refrigeration mode is calculated based on the availability of each of the cooling water pump assembly, the chiller assembly, and the chilled water pump assembly. For example, the usability of the cooling water pump component is A 1 Availability of chilled Water Pump part A 3 The usability of the water chilling unit component is A 4 If the cooling water pump component, the chilled water pump component and the chiller component are connected in series, the availability A of the set of heat exchange components in the refrigeration mode cooling ＝A 1 *A 3 *A 4 。
In response to the water cooling system being in a pre-cooling mode, a set of heat exchange assemblies includes a cooling water pump component, a chiller component, a heat exchanger, and a chilled water pump component. In this case, calculating the availability of the set of heat exchange assemblies in the precooling mode includes calculating the availability of each of the cooling water pump component, the chiller component, the heat exchanger, and the chilled water pump component; the availability of a set of heat exchange assemblies in the precooling mode is calculated based on the availability of each of the cooling water pump assembly, the chiller assembly, the heat exchanger and the chilled water pump assembly. For example, the usability of the cooling water pump component is A 1 The usability of the heat exchanger is A 2 Availability of chilled Water Pump part is A 3 The usability of the water chilling unit component is A 4 If the cooling water pump component, the heat exchanger, the water chilling unit component and the chilled water pump component are connected in series, the availability A of a set of heat exchange components in the precooling mode precooling ＝A 1 *A 2 *A 3 *A 4 。
In the embodiment, different structures of the set of heat exchange components in different working modes are fully considered, and then the availability of the set of heat exchange components is calculated according to the different working modes, so that the accuracy of the calculation of the availability of the set of heat exchange components is improved, and the accuracy of the calculation of the availability of the water cooling system is improved.
Since the water cooling system is often switched between a plurality of operation modes during actual operation, only one operation mode is used. For example, the operation mode of the water cooling system may be affected by the outdoor wet bulb temperature, and the seasonal variation may generally change the outdoor wet bulb temperature, so that the operation mode of the water cooling system may be switched according to seasons. In the process of calculating the availability of one set of heat exchange assembly, the time ratio of the water cooling system in each working mode can be taken into consideration, so that the availability of one set of heat exchange assembly is closer to the actual use condition of the heat exchange assembly, the availability of the water cooling system is closer to the actual use condition of the water cooling system, and the calculation of the availability of the water cooling system is more accurate.
In some embodiments, the time duty cycle of the water cooling system in each of the free cooling mode, the cooling mode, and the pre-cooling mode may be calculated separately. The time ratio here may be an annual time ratio, for example, the water cooling system is in the free cooling mode for 2 months in one year, in the cooling mode for 4 months, and in the precooling mode for 6 months, and the time ratios of the water cooling system in the free cooling mode, the cooling mode, and the precooling mode are 1/6, 1/3, and 1/2, respectively. The availability of a set of heat exchange assemblies is determined based on the time duty cycle of the water cooling system in each mode of operation and the availability of the set of heat exchange assemblies in each mode of operation, thereby determining the availability of the water cooling system based on the availability of the set of heat exchange assemblies.
As some implementation modes, it is assumed that the time ratio of the water cooling system in the free cooling mode, the refrigeration mode or the pre-cooling mode is x, y and z respectively, and the availability of one set of heat exchange components in the free cooling mode, the refrigeration mode and the pre-cooling mode is A respectively free-cooling 、A cooling And A precooling Availability a of a set of heat exchange assemblies total The method comprises the following steps:
A total ＝A free-cooling ·x+A cooling ·y+A precooling ·z
in the above embodiment, the availability of one set of heat exchange assembly is calculated based on the time ratio of the water cooling system in each working mode and the availability of one set of heat exchange assembly in the working mode, which is beneficial to obtaining a more accurate availability calculation result.
In some embodiments, as shown in fig. 1 and 3, a water cooling system includes multiple sets of heat exchange assemblies. In this case, calculating the availability of the plurality of heat exchange assemblies includes calculating the availability of the plurality of heat exchange assemblies based on the availability of one heat exchange assembly. For example, in the event that redundancy exists among the multiple heat exchange assemblies, an enumeration method, described below, may be employed to calculate the availability of the multiple heat exchange assemblies based on the availability of one heat exchange assembly.
In some embodiments, as shown in fig. 3 and 4, the water cooling system further includes a secondary pump component connected to the rear end of each set of heat exchange assemblies in the water cooling system. In this case, calculating the availability of the water cooling system further includes calculating the availability of the secondary pump components; and also calculate availability of the water cooling system based on availability of the secondary pump components.
As some implementations, the secondary pump component may include a plurality of secondary pumps, which may include actual operating secondary pumps and redundant secondary pumps. The availability of the secondary pump components can be calculated by utilizing an enumeration method according to the availability calculation result of the single secondary pump.
The redundancy availability calculation using the enumeration method may be, for example, as follows:
wherein lambda is out Representing the availability of secondary pump components, X represents the total number of secondary pumps in the secondary pump components, M represents the number of redundant secondary pumps in the secondary pump components, and λ is the availability of a single secondary pump. For ease of understanding, λ may be understood as the probability that a single secondary pump will not fail, 1- λ as the probability that a single secondary pump will fail, λ out The total number of the secondary pumps is X, and the X-M secondary pumps are operated without failure probability.
It should be appreciated that the above formula may also be used for redundancy availability calculations for other components comprising multiple identical devices. For example, for multiple sets of heat exchange assemblies, after the availability of one set of heat exchange assemblies is calculated, the availability of the multiple sets of heat exchange assemblies can be calculated by using an enumeration method. For another example, for multiple sets of cooling tower components in the ring network tower system, the availability of a single set of cooling tower components may be calculated, and then the availability of multiple sets of cooling tower components may be calculated by using an enumeration method. For another example, for multiple sets of water-cooling paths, after the availability of one set of water-cooling paths is calculated, the availability of multiple sets of water-cooling paths can be calculated by using an enumeration method. When the availability is calculated, the enumeration method is used for redundant availability calculation, so that the redundant design of the water cooling system is fully considered, and the availability calculation result of the water cooling system is more accurate.
In some embodiments, as shown in fig. 3 and 4, the water cooling system further includes a chilled water loop connected to the rear end of the heat exchange assembly in the water cooling system. In this case, calculating the availability of the water cooling system further comprises calculating the availability of a chilled water loop; and also calculate the availability of the water cooling system based on the availability of the chilled water loop. As some implementations, during the availability calculation of the chilled water loop, the redundancy availability calculation may also be performed using an enumeration method to take into account its redundancy.
In some embodiments, the water cooling system further includes one or more air conditioners (not shown) connected to the rear end of the heat exchange assembly in the water cooling system. In the case where the water cooling system includes a set of heat exchange assemblies, one or more sets of air conditioners may be connected to the rear end of the set of heat exchange assemblies. In the case where the water cooling system includes multiple sets of heat exchange assemblies, one or more sets of air conditioners may be connected to the rear end of the entirety of the multiple sets of heat exchange assemblies. In this case, calculating the availability of the water cooling system further includes calculating the availability of one or more sets of air conditioners (for example, in the case of including multiple sets of air conditioners, the availability of multiple sets of air conditioners may be obtained by performing redundant availability calculation by using an enumeration method according to the availability calculation result of a single set of air conditioners); and also based on a set of Or availability of a plurality of sets of air conditioners (for example, availability a of a water cooling system described later is calculated) 11 In the continuous multiplication formula of (2), the availability of one or more sets of air conditioners is multiplied. As some implementations, in the case that air conditioner redundancy exists in multiple sets of air conditioners, redundancy availability calculation can be performed by using an enumeration method according to the availability calculation result of a single precise air conditioner so as to obtain the availability calculation result of the multiple sets of air conditioners.
In some embodiments, as shown in FIG. 1, the water cooling system further includes a valve, the availability of which may be taken into account in calculating the availability of the water cooling system.
The following describes the calculation of availability of cooling tower components, cooling water pump components, chiller components in connection with some embodiments.
In some embodiments, each of the one or more sets of cooling tower components includes one or more cooling tower members. Each cooling tower component comprises a cooling tower, a frequency converter connected with the cooling tower and a power supply system connected with the cooling tower. Calculating availability of a set of cooling tower components includes calculating availability of a cooling tower, a frequency converter connected to the cooling tower, and a power supply system connected to the cooling tower; calculating an availability of each cooling tower component based on the availability of the cooling tower, a frequency converter connected to the cooling tower, and a power supply system connected to the cooling tower; the availability of each set of cooling tower components is calculated based on the availability of each cooling tower component. After the availability of each set of cooling tower components is calculated, the availability of multiple sets of cooling tower components may be calculated based on the availability of each set of cooling tower components. For example, an enumeration process may be used to perform redundant availability calculations to obtain the availability of multiple sets of cooling tower components.
