Embodiment 1

[0036] This embodiment provides an integral double cold source composite heat exchange coil, the cold source is chilled water from a central air conditioner, and the other cold source is refrigerant. Its main purpose is to ensure the normal operation of the dual cooling source computer room air conditioner using chilled water and refrigerant for cooling. Chilled water is the main cooling source. After the central air conditioner is turned off, it is supplemented with refrigerant cooling. Compared with all refrigerant cooling, the PUE value of the machine room is greatly reduced. Compared with all cooling water cooling, it can Ensure that the central air conditioner can achieve cooling effect after it is turned off, and ensure that the air conditioner in the computer room can run normally 24 hours a day, 365 days a year, which not only achieves the purpose of reducing energy consumption, but also ensures that the computer room is always smart without affecting the performance of...

Embodiment 2

[0040] In this embodiment, on the basis of Embodiment 1, the connector 3 is optimized. The connector 3 includes a top plate 30 and a support plate. On the right core body 11, the middle is connected on the herringbone core body 20. The top plate is provided with a matts 31, and the matts 31 is provided with a hollow 32. The left and right cores adopt a "﹀" type integral matt roof, which can reduce the weight of the coil, and the "﹀" type can avoid air leakage in the gap between the left and right cores.

[0041] The support plate includes a left support plate 33 and a right support plate 34, the cross section of the support plate is trapezoidal, and a drainage hole 35 is arranged on the support plate, and the left support plate 33 is installed on the bottom of the left core 10 and the herringbone core 20, with drainage One end of the hole 35 is located at the bottom of the left core 10, the right support plate 34 is installed at the bottom of the right core 11 and the herring...

Embodiment 3

[0043] In this embodiment, on the basis of Embodiment 1, the refrigerant return header, chilled water inlet header, and chilled water outlet header are refined, and the specific structure is as follows:

[0044] The refrigerant return manifold includes a left refrigerant return pipe 21, a right refrigerant return pipe 22 and a horizontal refrigerant return pipe 23. One end of the horizontal refrigerant return pipe 23 is connected to the left refrigerant return pipe 21, and the other end is connected to On the right refrigerant return pipe 22, the horizontal refrigerant return pipe 23 is provided with an air return port, and the left refrigerant return pipe 21 communicates with the heat exchange coil 4 on the left side of the herringbone core body 20, and the right refrigerant The air return pipe 22 communicates with the heat exchange coil 4 on the right side of the herringbone core 20 .

[0045] The refrigerant distributor 24 communicates with the heat exchange coils 4 on the ...

Abstract

The invention discloses an integrated type double cold source recombination heat exchange coil. The integrated type double cold source recombination heat exchange coil pipe comprises a freeze water heat exchange coil, a refrigerating fluid heat exchange coil and connecting pieces. The freeze water heat exchange coil comprises a left core body, a right core body, a freeze water inlet collecting pipe and a freeze water outlet collecting pipe; the refrigerating fluid heat exchange coil comprises an inverted-V-shaped core body, the left core body is located on the left side of the inverted-V-shaped core body, the right core body is located on the right side of the inverted-V-shaped core body, and the left core body, the inverted-V-shaped core body and the right core body are connected into a whole through the connecting pieces. According to the integrated type double cold source recombination heat exchange coil, freeze water can be used for refrigerating, and refrigerating fluid can further be used for evaporative refrigerating. When a central air-conditioning is started, the freeze water of the central air-conditioning is used to conduct refrigerating, and after the central air-conditioning is shut down, the refrigerating fluid is used to conduct evaporative refrigerating, not only is the energy consumption reduced, but also the fact that machine room equipment can be refrigerated for 24 hours in 365 days is ensured. The design of the integrated type recombination heat exchange coil further reduces the size of the double cold source air-conditioning, and the construction of the machine room is better facilitated.

Description

technical field [0001] The invention belongs to the technical field of machine room air conditioners, and relates to an integral double cold source composite heat exchange coil that can utilize chilled water for refrigeration and refrigerant evaporation and heat absorption for refrigeration. Background technique [0002] With the rapid development of data centers, the computer room has entered the era of high computing and high power density, and the power consumption of the computer room has accounted for 1.5% of the electricity consumption of the whole society. High-efficiency and energy-saving data centers are an inevitable trend in the development of the industry. The energy consumption of computer room air conditioners accounts for 30-45% of the total energy consumption of the computer room, resulting in a high PUE value of the data center (total energy consumption of the data center / energy consumption of IT equipment). At the same time, the space of the computer room i...
