Description

Technical Field

[0001] This utility model relates to the technical field of fresh air cooling systems, specifically to a cooling air device suitable for data centers. Background Technology

[0002] An air-cooled system is an air conditioning system that can be applied to data centers. By introducing fresh outdoor air into the data center to cool heat-generating equipment, it significantly reduces the energy consumption of the air conditioning system.

[0003] In cold regions, data centers using existing traditional direct fresh air cooling systems consume a large amount of water for humidification, increasing the pressure on water supply in water-scarce areas. Furthermore, low temperatures can cause humidification water pipes to freeze and crack. To prevent pipe freezing, electric heat tracing is required for the humidification water pipes, increasing energy consumption.

[0004] In view of this, we propose a fresh air cooling system suitable for computer rooms, which effectively solves the energy consumption problem in low-temperature areas. Utility Model Content

[0007] Furthermore, the humidification component is a humidifier. In practical applications, this device can be either spray humidification or wet film humidification.

[0008] Furthermore, the cooling assembly includes an evaporator; the refrigeration unit includes a compressor, a condenser, and an expansion valve; wherein one end of the evaporator is connected to one end of the compressor; the other end of the compressor is connected to one end of the condenser; the other end of the condenser is connected to one end of the expansion valve; and the other end of the expansion valve is connected to the other end of the evaporator. In practical applications, this design is mature and can achieve sustainable output cooling, and its components are conventional and easy to implement.

[0009] Furthermore, the refrigeration unit also includes two one-way valves; one of these valves is installed between the evaporator and the condenser, and connected in series with the compressor; the other valve is installed between the condenser and the expansion valve. In practical applications, this design aims to operate in low-temperature environments. This eliminates the need for a compressor, directly transferring the temperature from the external low-temperature environment to the condenser, thereby achieving refrigeration. This saves the energy required by the compressor, resulting in significant energy savings.

[0010] Furthermore, the refrigeration unit also includes a refrigerant pump; one end of the refrigerant pump is connected to the condenser, and the other end is connected to the evaporator.

[0012] Furthermore, it also includes an exhaust fan unit, which is installed in the data center for ventilation. This design is a conventional exhaust fan.

[0013] As can be seen from the above technical solution, the beneficial effects of the cooling air device for data centers provided by this utility model are as follows:

[0014] In practical applications, the use of a recovery liquid tank and pump in energy-saving components can reduce the humidification water consumption of direct fresh air cooling systems.

[0022] like Figure 1-2 As shown in the figure, this embodiment provides a cooling air device suitable for data centers, which can solve the energy consumption problem in low-temperature areas.

[0023] This utility model provides a cooling air device suitable for data centers, comprising: a fan unit 1, wherein the fan unit 1 is equipped with an outdoor fresh air unit 11 and an indoor return air unit 12, wherein the outdoor fresh air unit 11 is used to supply fresh air from the outside to the inside of the data center, and the indoor return air unit 12 is used to output indoor airflow to the outside; and a functional component 2, wherein the functional component 2 is disposed between the outdoor fresh air unit 11 and the data center; the functional component 2 includes a filter component 21, a humidification component 22, a cooling component 23, and a pressurization component 24; wherein the outdoor fresh air unit 11, the filter component 21, the humidification component 22, the cooling component 23, and the pressurization component The components 24 are connected sequentially; wherein the filter component 21 is used to filter the fresh air flow; the humidification component 22 humidifies the fresh air flow; the cooling component 23 is used to cool the humidified fresh air flow; the pressurization component 24 is used to pressurize the air flow; both the filter component 21 and the cooling component 23 are passively operated; the energy-saving component 3 includes a chiller 31, a recovery liquid tank 32, and a liquid pump 33; the chiller 31 is connected to one end of the cooling component 23; one end of the recovery liquid tank 32 is connected to the cooling component 23 through the liquid pump 33; the other end of the recovery liquid tank 32 is connected to the humidification component 22. In actual operation, the recovery liquid tank 32 and the liquid pump 33 in the energy-saving component 3 can reduce the humidification water consumption of the direct fresh air cooling system. It also reduces the risk of freezing and cracking of the humidification water pipes and effectively reduces the power consumption of electric heat tracing for the humidification water pipes.

[0024] In this embodiment, the humidification component 22 is a humidifier. In practical applications, this device can be a spray humidifier or a wet film humidifier.

[0025] In this embodiment, the cooling assembly 23 includes an evaporator 231; the refrigerator 31 includes a compressor 311, a condenser 312, and an expansion valve 313; wherein one end of the evaporator 231 is connected to one end of the compressor 311; the other end of the compressor 311 is connected to one end of the condenser 312; the other end of the condenser 312 is connected to one end of the expansion valve 313; and the other end of the expansion valve 313 is connected to the other end of the evaporator 231. In practical applications, this design is mature and can achieve sustainable output cooling, and its components are conventional and easy to implement.

[0026] In this embodiment, the refrigeration unit 31 further includes two one-way valves 314; one of the one-way valves 314 is installed between the evaporator 231 and the condenser 312, and is connected in series with the compressor 311; the other one-way valve 314 is installed between the condenser 312 and the expansion valve 313. In practical applications, the purpose of this design is to operate in low-temperature environments. This eliminates the need for the compressor 311, directly transferring the temperature of the external low-temperature environment to the condenser 312, thereby achieving refrigeration. This saves the energy required by the compressor 311, resulting in significant energy savings.

[0027] In this embodiment, the refrigeration unit 31 further includes a refrigerant pump 315; one end of the refrigerant pump 315 is connected to the condenser 312, and the other end of the refrigerant pump 315 is connected to the evaporator 231.

In outdoor low-temperature environments, the refrigerant pump 315 circulates the cooling working fluid, providing cooling capacity for the direct fresh air cooling system while simultaneously utilizing the natural cooling capacity of the environment. The two check valves 314 are used to prevent short-circuiting of the refrigerant circulation.

The cooling assembly 23 is used, and the condenser 312 and refrigerant pump 315 in the chiller 31 are run. This operating mode allows the air conditioning system to provide natural cooling without introducing fresh air. Simultaneously, by not introducing fresh air with low moisture content, the amount of water used for humidification is reduced. The cooling medium temperature may be lower than the dew point temperature of the air within the system, causing condensation and reducing the humidity in the computer room. The recovery liquid tank 32 and liquid pump 33 can recover the condensate and return it to the humidification assembly 22, ensuring the condensate is returned to the system air and preventing the room humidity from falling below the set lower limit for the computer room humidity.

[0032] In summary, this cooling device for data centers is not only reasonably designed and easy to operate, but also effectively saves energy and reduces energy consumption. It is also suitable for use in cold regions, and therefore, this device is suitable for industry promotion.
