The invention provides an air conditioning system which can be applied to a machine room of a data center and used for cooling cabinet equipment. In the following embodiments, an example in which an air conditioning system is applied to a machine room of a data center is mainly used for description, and other cases requiring the air conditioning system may be referred to for implementation.

Referring to fig. 1, an air conditioning system 10 includes a cooling module 100, an end module 200, and an integrated pipe module 300, wherein the cooling module 100 is generally installed outdoors to provide a cooling source for the end module 200. The end module 200 is typically installed in a room to cool the rack equipment. For example, the end module 200 may be installed in a room and connected to cabinet equipment plumbing. The integrated circuit module 300 is used to connect the cooling module 100 and the end module 200 such that a refrigerant can be circulated between the cooling module 100 and the end module 200, thereby allowing the air conditioning system 10 to perform a cooling function. In addition, the cooling module 100, the end module 200 and the integrated pipeline module 300 of the air conditioning system 10 can be arranged in a modularized manner, which is beneficial to installation and use of the air conditioning system 10, simplifies field installation and piping, improves construction efficiency of engineering, enlarges the application range of the air conditioning system 10, and improves practicability and convenience of the air conditioning system 10.

Referring to fig. 1 and fig. 2, the cooling module 100 includes a natural cooling unit 110 and a chilled water cooling unit 120, that is, the cooling module 100 has two cooling sources, integrates two heat dissipation methods, and can be selectively used according to the requirement. Due to the difference between different time periods and the outdoor temperature, the air conditioning system 10 may selectively use the cold source of the cooling module 100 according to the outdoor temperature, and the integrated pipeline module 300 is used to realize switching the natural cooling unit 110 or the cooling water unit of the cooling module 100 as a suitable cold source. For example, when the outdoor temperature is low (e.g., below 18 ℃), the free cooling unit 110 may be selected to provide a cooling source for the end module 200. The chilled water chiller 120 may be selected to provide a heat sink for the end module 200 when the outdoor temperature is high (e.g., above 25 ℃). The selection of a suitable heat sink may increase the efficiency of the air conditioning system 10 and reduce the energy consumption of the air conditioning system 10.

The free cooling unit 110 includes a first heat exchanging coil 113, and the first heat exchanging coil 113 is provided with a first coolant inlet 111 and a second coolant inlet 121. The first heat exchanging coil 113 is pipe-connected to the integrated piping module 300 through the first coolant inlet 111 and the first coolant outlet 112, thereby connecting the free cooling unit 110 and the integrated piping module 300.

The natural cooling unit 110 further comprises a fan 114, when the coolant flows to the first heat exchange coil 113 of the natural cooling unit 110 from the terminal module 200, the coolant can conduct heat to the first heat exchange coil 113, the fan 114 can drive airflow to flow to the first heat exchange coil 113, and the surface of the first heat exchange coil 113 is cooled, so that heat dissipation of the coolant is completed, heat is taken away, the temperature of the coolant is reduced, and a cold source is provided for the terminal module 200. Therefore, when the outdoor temperature is low, the natural cooling unit 110 can effectively provide a cold source for the end module 200, which is beneficial to improving the working efficiency, saving energy and reducing the energy consumption of the air conditioning system 10.

The free cooling unit 110 further includes a cooling tower 115. The cooling tower 115 may be a closed cooling tower or an open cooling tower. As the coolant flows from the end module 200 to the first heat exchanging coil 113 of the free cooling unit 110, the coolant may conduct heat to the first heat exchanging coil 113. The cooling tower 115 may spray the moisture onto the first heat exchange coil 113 such that the moisture may evaporate on the surface of the first heat exchange coil 113. The evaporation of water can take away part of the heat on the surface of the first heat exchange coil 113, thereby taking away part of the heat of the coolant, completing the heat dissipation of the coolant, taking away the heat, reducing the temperature of the coolant, and providing a cold source for the terminal module 200. In this way, the natural cooling unit 110 can provide a cold source for the end module 200 more effectively, thereby improving the heat dissipation efficiency, saving energy, and reducing the energy consumption of the air conditioning system 10.

The chilled water chiller 120 includes a second heat exchange coil 123, and the second heat exchange coil 123 includes a second coolant inlet 121 and a second coolant outlet 122. The second heat exchanging coil 123 is pipe-connected to the integrated piping module 300 through the second coolant inlet 121 and the second coolant outlet 122, thereby connecting the chilled water chiller 120 and the integrated piping module 300.

The chilled water chiller 120 includes a refrigeration device 124, and the refrigeration device 124 may be an ice maker or the like that can produce refrigeration. The refrigeration unit 124 is in heat conducting connection with the second heat exchanging coil 123 via a heat transfer medium, which may be water. The coolant flows from the end module 200 to the second heat exchanging coil 123, and the refrigeration device 124 can exchange heat with the second heat exchanging coil 123 to take away heat and provide a cold source for the end module 200. Therefore, when the outdoor temperature is high, the chilled water cooling unit 120 can effectively provide a cold source for the end module 200, which is beneficial to improving the heat dissipation efficiency, saving energy and reducing the energy consumption of the air conditioning system 10.
