Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figures 1-4 , a cooling energy-saving system for computer room equipment, including cabinets 2 arranged inside the computer room 1. Two rows of cabinets 2 form a group, and a closed cold channel 3 is formed between the cabinets 2 in each group. The outside of the closed cold channel 3 is an open hot channel 4. A ventilation system is arranged outside the computer room 1, a precooling system is arranged below the ventilation system, and a refrigeration system is arranged between the precooling system and the computer room 1.

[0034] An air inlet pipe 7 is arranged at the bottom end of the computer room 1. A first air inlet 5 is opened on the side wall of the air inlet pipe 7, a second air inlet 6 is opened on the upper side wall of the air inlet pipe 7, three air supply ports 8 are opened on the upper side wall of the air inlet pipe 7, three air outlet ports 9 are opened on the upper side wall of the computer room 1, and the air outlet ports 9 are communicated with an air outlet pipe 10.

[0035] The ventilation system includes a fan 111. The fan 111 is arranged outside the computer room 1, and the fan 111 is communicated with a first pipe 112. A first filter 113 is arranged on the first pipe 112.

[0036] One end of the first pipe 112 away from the fan 111 is provided with a first electric three-way valve 114. One end of the first electric three-way valve 114 away from the first filter 113 is communicated with a second pipe 115. One end of the second pipe 115 away from the first electric three-way valve 114 is provided with a second electric three-way valve 116. One end of the second electric three-way valve 116 away from the second pipe 115 is provided with a fourth pipe 1191. A second filter 117 is arranged on the fourth pipe 1191.

[0037] One end of the fourth pipe 1191 away from the second electric three-way valve 116 is communicated with a third electric three-way valve 118. One end of the third electric three-way valve 118 away from the second filter 117 is communicated with a third pipe 119, and the third pipe 119 is communicated with the first air inlet 5.

[0038] Working process: When the fan 111 runs, when the exhausted air passes through the first pipeline 112, it is filtered by the first filter 113. The filtered air sequentially passes through the first filter 113, the first electric three-way valve 114, the second pipeline 115, the second electric three-way valve 116, and the fourth pipeline 1191. When passing through the fourth pipeline 1191, it is filtered by the second filter 117 again. The incoming air passes through the third electric three-way valve 118 and the third pipeline 119, and is discharged into the air inlet pipeline 7 through the first air inlet 5. The gas in the air inlet pipeline 7 is discharged into the enclosed cold channel 3 through the air supply port 8. The air in the enclosed cold channel 3 of the cabinet 2 exchanges heat with the cabinet 2, reducing the temperature of the cabinet 2 and keeping it within the appropriate working temperature range, thereby ensuring the stable operation of the cabinet 2 and extending its service life.

[0039] The air passing through the cabinet 2 expands and contracts due to heat, causing the hot air to move upward. The hot air is discharged to the outside through the air outlet 9 and the air outlet pipe 10.

[0040] Embodiment 2:

[0041] Please refer to Figures 1-4 , on the basis of Embodiment 1, this embodiment provides a technical solution for a cooling and energy-saving system for computer room equipment: The precooling system includes a fifth pipeline 121 and a square groove 126. The square groove 126 is arranged below the first electric three-way valve 114. The fifth pipeline 121 is arranged below the first electric three-way valve 114. A heat exchanger 122 is arranged below the fifth pipeline 121, and the heat exchanger 122 is arranged in the square groove 126.

[0042] A heat dissipation pipeline 124 is connected to the heat exchanger 122. A circulation pump 123 is arranged below the heat exchanger 122. The circulation pump 123 is connected to the heat dissipation pipeline 124. One end of the heat dissipation pipeline 124 is connected to a number of heat dissipation branch pipelines 125.

[0043] A heat dissipation main pipe 127 is connected to the lower side of the heat exchanger 122. A heat exchange branch air pipeline 129 is connected to the heat dissipation main pipe 127. A first regulating valve 128 is arranged at the input port of the heat exchange branch air pipeline 129. A second regulating valve 1291 is arranged at the output port of the heat exchange branch air pipeline 129. One end of the second regulating valve 1291 away from the heat dissipation main pipe 127 is connected to a sixth pipeline 1292. A first temperature sensor 1293 is arranged in the enclosed cold channel 3, and a second temperature sensor 1294 is arranged inside the open hot channel 4.

[0044] Working process: When the external temperature is too high, after being detected by the first temperature sensor 1293 and the second temperature sensor 1294, the temperature of the air discharged into the computer room 1 is difficult to reduce the temperature of the cabinet 2. Through the controller, the first electric three-way valve 114 and the second electric three-way valve 116 are adjusted so that the first pipeline 112 is connected to the fifth pipeline 121, and the sixth pipeline 1292 is connected to the fourth pipeline 1191.

[0045] The fan 111 discharges air into the first pipeline 112, and after being filtered by the first filter 113, it is discharged into the fifth pipeline 121. The air enters the heat exchanger 122, and after heat exchange, the air temperature is reduced. The coolant of the heat exchanger 122 is circulated by the circulation pump 123, so that the coolant flows along the heat dissipation pipeline 124 and the heat dissipation branch pipeline 125, and heat exchange is carried out between the soil and the coolant in the heat dissipation pipeline 124 and the heat dissipation branch pipeline 125. When the coolant flows in the pipeline, heat exchange is carried out with the surrounding underground soil. The temperature of the underground soil is relatively stable and low, and it can absorb the heat in the coolant to cool the coolant.

[0046] At the same time, through the setting of the circulation pump 123, the coolant is forced to circulate in the pipeline, which is convenient for more effectively controlling the flow rate and flow velocity of the cooling medium and improving the heat exchange efficiency.

[0047] The cooled air passes through the first regulating valve 128, the heat exchange branch air pipeline 129, the second regulating valve 1291 and the sixth pipeline 1292 to cool the air twice. The cooled air cools the cabinet 2 through the fourth pipeline 1191, the third pipeline 119, the first air inlet 5, the air inlet pipeline 7 and the air outlet 8.

[0048] The pre-cooling system realizes the purpose of reducing the air temperature through the heat exchange between air and soil. As an auxiliary system of the refrigeration system, it is used in the transitional season or some periods, and has the functions of low maintenance cost and energy conservation and emission reduction.

[0049] When the temperature is difficult to reach the specified value after being detected by the first temperature sensor 1293 and the second temperature sensor 1294, the power of the fan 111, the power of the circulation pump 123, the opening degree of the first regulating valve 128 and the opening degree of the second regulating valve 1291 are controlled by the controller to adjust the temperature.

[0050] In this embodiment, the controller can adopt a single-chip microcomputer or a PLC controller. Controlling the switches of the fan, the circulation pump, etc. and the actions of the control valves by the single-chip microcomputer or the PLC controller are common technologies in the prior art, and their structures and control principles are all prior art.

[0053] The output end of the precision air conditioner 133 is communicated with the second air inlet 6, and the precision air conditioner 133 is communicated with the cold air outdoor unit 132 through a pipeline.

[0054] Working process: when the outside temperature is high and it is difficult to reach the required temperature through the precooling system, the third electric three-way valve 118 is adjusted through the controller, so that the air passes through the seventh pipeline 131 and enters the precision air conditioner 133, and then through the third heat exchange of the seventh pipeline 131, the air is cooled again to adjust the temperature in the computer room 1.

[0055] The air is cooled twice by the precooling system, reducing the refrigeration load of the refrigeration system and the energy consumption of the refrigeration system.
