Embodiment 1

[0047] Such as figure 1 As shown, the top-mounted data center refrigeration system in this embodiment includes two rows of cabinets 2 arranged face to face at the air inlet ends, an access door, a ventilation hole plate 7, and a cold aisle 1 surrounded by the floor of the machine room; that is to say figure 1 The front end of the intercooler aisle 1 is provided with the passage door, and a row of cabinets 2 are respectively arranged on both sides of the cold aisle 1, and a ventilation hole plate 7 is arranged above the cold aisle 1; the length of the cold aisle 1 is not Less than the length of a single row of cabinets, and the width of the cold aisle 1 is not less than twice the depth of the cabinet 2; preferably, the airtight connection between the ventilation hole plate 7 and the top of the cold aisle 1 is. Further preferably, the width of the cold aisle 1 after opening the aisle door is the width of the cold aisle 1 . And preferably, the material of the access door is a tr...

Embodiment 2

[0054] The difference between this embodiment and the first embodiment is that the top of the plenum box 6 is provided with a movable sunroof 8 corresponding to the position of the ventilation hole plate 7 . When a fire breaks out, the movable sunroof 8 is fully opened, and the fire-fighting gas enters the inside of the cold aisle 1 for gas fire extinguishing. Preferably, a movable sunroof 8 is provided on the top of the plenum box 6 at the position of the fire sprinkler head. For details, please refer to the attached Figure 4 ~ Figure 5 .

[0055] To sum up, in the top-mounted data center refrigeration system of the present invention, the hot air discharged from the air outlet of the cabinet enters the air return device, and then is sent to the return air pipe above the cabinet by the air return device. One side of the air return pipe is connected with the air return device, and the other side is connected with the static pressure box, and a heat exchanger is installed ins...

Abstract

The present invention provides a top-mounted data center refrigeration system, comprising: two rows of cabinets arranged face-to-face at the air inlet ends; an air return device connected to the air outlet end of the cabinets; Plenum box; ventilation hole plate at the bottom of the static pressure box; cold aisle surrounded by cabinets, access doors, ventilation holes, and the floor of the machine room. The hot air discharged from the air outlet end of the cabinet is sent to the heat exchanger for cooling through the air return device. The heat exchanger is located in the return air pipe, one side of the return air pipe is connected with the air return device, and the other side is connected with the static pressure box. The cooled air enters the static pressure box, mixes and stabilizes, and then is sent to the cold aisle through the vent plate. The cabinet then inhales the cold air in the cold aisle and discharges it to complete the cooling cycle. This system saves the energy consumption of the fan at the end of the air conditioner, and improves the problem that the air supply speed of the ordinary top air supply system is too fast, the air intake of the server on the upper part of the cabinet is small, and local hot spots are likely to occur. overall cooling efficiency.

Description

technical field [0001] The invention relates to a data center refrigeration system, in particular to a top-mounted data center refrigeration system. Background technique [0002] The data center's demand for energy is ultimately reflected in the demand for electrical energy. At present, the energy consumption of IT equipment only accounts for 30% of the energy consumption of the entire data center, while the energy consumption of cooling equipment accounts for 50%-60%. The cooling system is the largest energy consumer in the data center computer room. Recently, large-scale, high-density, and data-concentrated data centers are becoming more and more popular, and the heat dissipation problem of high-density server rooms is becoming more and more difficult to solve. The use of traditional precision air-conditioning systems presents a huge energy consumption, and the PUE value remains high. status. Therefore, the energy saving of the air conditioning system is the core of the...
