Embodiment 1

[0048] see figure 1 , the air conditioning system provided by the embodiment of the present application includes a fan 10 , a heat exchanger 20 and a pipeline assembly 30 . Wherein, in this embodiment, the air conditioning system is applied in the data center computer room. Of course, according to actual usage requirements, the air conditioning system can also be applied in other indoor spaces such as workshops and warehouses.

[0049] Specifically, the fan 10 is used for air circulation; it can be understood that the fan 10 is used for air supply and return air. During operation, the fan 10 supplies air to the indoor space, and the return air from the indoor space will return to the fan 10, and finally pass through the fan 10 is sent out into the indoor space again, that is, the fan 10 realizes the circulation of the wind, that is, the fan 10 realizes the circulation of the air; wherein, the wind and air in this embodiment can be interpreted in the same way.

Embodiment 2

[0122] see image 3 , the difference between this embodiment and the first embodiment is:

[0123] The first valve group 41 does not include the first three-way valve 411, but includes a first on-off valve 412 and a second on-off valve 413. The first on-off valve 412 is arranged on the first branch pipe 331, and the second on-off valve 413 is arranged on the first on-off valve 412. On the three branch pipes 333 ; the first on-off valve 412 and the second on-off valve 413 can be selectively opened to control the first water inlet pipe 31 to be connected to the first branch pipe 331 or to the third branch pipe 333 . Exemplarily, when the first switch valve 412 is opened and the second switch valve 413 is closed, the first water inlet pipe 31 is connected to the second water inlet pipe 211 through the first branch pipe 331 , and the first water inlet pipe 31 and the third branch pipe are connected to each other. 333 is not connected; when the first on-off valve 412 is closed and...

Abstract

The application is applicable to the technical field of air-conditioning, and provides an air-conditioning system and a control method thereof. The air-conditioning system includes a fan, a heat exchanger and a pipeline assembly; the fan is used for air circulation; the heat exchanger has a first heat exchange state and a second heat exchange state. thermal state; the pipeline assembly includes a first water inlet pipe and a first water outlet pipe, and the first water inlet pipe and the first water outlet pipe are respectively connected to the heat exchanger to circulate the heat exchange medium together with the heat exchanger; the first water inlet pipe and The first water outlet pipe is configured to put the heat exchanger in the first heat exchange state when the cooling demand is less than or equal to the first preset threshold value, so as to provide heat exchange between the heat exchange medium and the wind of the fan in the same direction, and is also configured to make the cooling When the demand is greater than the second preset threshold, the heat exchanger is placed in a second heat exchange state, so that the heat exchange medium and the wind of the fan reverse heat exchange. In this way, when the cooling demand is less than or equal to the first preset threshold, the sensible heat ratio is increased while meeting the cooling demand, which can reduce the energy consumption of the air conditioning system.

Description

technical field [0001] The present application belongs to the technical field of air conditioning, and more particularly, relates to an air conditioning system and a control method thereof. Background technique [0002] When the traditional computer room air conditioner is running, the sensible heat is relatively low, generally below 90%, and the latent heat cooling capacity is large. The computer room air conditioner will generate a large amount of condensed water during cooling operation, which will reduce the air humidity in the computer room. The heat ratio is the ratio of the sensible heat cooling capacity to the total cooling capacity, and the total cooling capacity is the sum of the sensible heat cooling capacity and the latent heat cooling capacity. [0003] In order to maintain the air humidity in the computer room within the preset range, it is generally necessary to turn on the humidifier to increase the air humidity in the computer room; this setting adds unneces...
