Embodiment 1

[0039] The distributed data center heat recovery heating system provided in this embodiment, such as figure 2 As shown, it includes: a cabinet 1, a server 2, and a heat recovery and heating module 3. The server 2 is discretely installed in the cabinet 1 , and the cabinet 1 is connected to the heat recovery and heating module 3 , and a cooling fan 11 and an air vent 12 are also arranged in the cabinet 1 .

[0040] The heat recovery heating module 3 includes a heat exchanger 301 , an indoor air outlet pipe 307 , an indoor air outlet pipe damper 309 , an outdoor air outlet pipe 312 , and an outdoor air outlet pipe damper 314 .

[0041] One side of the heat exchanger 301 is embedded in the cabinet 1, and the other side is connected to the indoor air outlet pipe 307 and the outdoor air outlet pipe 312 respectively through a structure similar to a three-way pipe. The indoor air outlet pipe 307 is installed indoors and connected to the indoor air outlet pipe. The air outlet pipe damp...

Embodiment 2

[0045] Embodiment 2 On the basis of Embodiment 1, a water-cooled coil condenser 315 and a heat storage tank 316 are added. The input end of the water-cooled coil condenser 315 is connected to the refrigerant outlet of the heat exchanger 301 through a compressor 317 , and the output end of the water-cooled coil condenser 315 is connected to the refrigerant inlet and outlet of the heat exchanger 301 through a throttling device 305 . The water-cooled coil condenser 315 is arranged inside the heat storage tank 316, such as image 3 shown.

[0046] When the compressor 317 and the throttling device 305 are turned on, and the air valve 309 of the indoor air outlet pipe and the indoor air outlet pipe 307 are closed, based on the principle of forced convection, the heat recovery heating module 3 operates in the heat pump circulation mode to obtain a higher temperature The domestic hot water is stored in the hot water storage tank 316 .

[0047] The working method of this embodiment i...

Embodiment 3

[0053] This example Figure 5 As shown, it includes a cabinet 1, a server 2, and a heat recovery and heating module 3. Wherein, the heat recovery heating module 3 includes an evaporator 302, a compressor 317, a heat dissipation branch valve 308, an air-cooled condenser 311, a heat storage branch valve 313, a water-cooled coil condenser 315, a heat storage tank 316, a flow device 305 . The heat dissipation branch valve 308 is connected with the air-cooled condenser 311 to form a heat dissipation branch; the heat storage branch valve 313, the water-cooled coil condenser 315, and the hot water storage tank 316 form a heat storage branch, and the heat storage branch valve 313 is connected to the water-cooled The coil condenser 315 and the cold coil condenser 315 are arranged inside the heat storage tank 316 .

[0054] The evaporator 302 is connected in parallel with the heat dissipation branch and the heat storage branch respectively, and the input ends of the evaporator 302 and...

Abstract

The invention discloses a distributed data center heat recovery and heating system, which relates to the intersection fields of HVAC and information network. The invention includes: a cabinet, a server and a heat recovery heating module. The server is located inside the cabinet and placed in the user's home to provide data computing and storage capabilities for local and remote users; the heat recovery and heating module recovers the waste heat of the server to provide heat for local users. In the present invention, the servers that were originally placed centrally are distributed in the user's home or local community, and the heat dissipation of the server is used to provide heat to the user's home, so as to improve the utilization rate of waste heat in the data center; when there is no need for heat supply, the excess heat is dissipated into the surrounding environment , the heat dissipation is relatively dispersed, and the efficiency is higher, which effectively weakens the local heat accumulation effect and ensures the stable operation of the server. It not only solves the shortcomings of the centralized data center, such as large footprint, high construction and operation and maintenance costs, and difficult heat dissipation, but also uses the heat dissipation of equipment servers to provide heat for homes.

Description

technical field [0001] The invention relates to the intersecting field of HVAC and information network, in particular to a distributed data center heat recovery heating system. Background technique [0002] With the exponential growth of the amount of processed data, the data center (IDC) as a data storage / exchange hub is developing rapidly. According to statistics, at present, the number of various data centers in my country has exceeded 500,000, and the number of cabinets has exceeded 6 million. The number and area of ​​data centers have leapt to the second place in the world. The data center is developing very fast and the market potential is huge. However, traditional centralized data centers have the following problems: 1) In traditional data centers, all electronic equipment is usually placed centrally, which makes the heat dissipation of the equipment too large and concentrated (the heat dissipation per unit area reaches 1000W / m2), making it difficult to dissipate he...
