[0029] In traditional data center cooling solutions, the heat generated by the data center is directly taken away by chilled water and transferred to the outdoor environment through a cooling tower. It is impossible to flexibly adjust according to outdoor environmental conditions and use natural cold sources for cooling. The utility model realizes efficient recovery and utilization of waste heat in the data center by setting up a waste heat recovery system. For the heat generated by the data center, the waste heat is first recovered through a heat pump system. The hot water return water is heated up after heat exchange through the condenser and enters the hot water storage tank for storage. It is used for domestic hot water and winter heating in surrounding buildings throughout the year. The data center return air after heat recovery enters the cooling system for cooling, and is sent to the data center after cooling. In order to solve the problem of adaptive adjustment according to the external environment, the utility model sets up a heat pipe system and an air conditioning system. Through real-time switching, the frequency of the compressor is adjusted according to the hot water return water temperature and the data center supply air temperature, so as to achieve the use of natural cold energy to adapt to different temperature conditions. The utility model can effectively avoid the compressor from running all day, reduce the maintenance frequency of the compressor, and at the same time reduce energy consumption, making it convenient to reduce consumption and gain to achieve energy saving effects;

[0030] In addition, the utility model can enhance the reliability of the system by using a heat storage tank to maintain the heat used at the terminal. The water outlet of the waste heat recovery system condenser is connected to the heat storage tank. When the waste heat recovery system of the data center fails, the heat storage tank can maintain the heat used at the terminal.

[0031] The intelligent controller of the utility model can directly regulate the cooling and heating systems by measuring the heat at multiple positions without manual adjustment, and can ensure the continuity of control. It is more suitable for the computer room environment with continuous output throughout the day, and its regulation method is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In one of the embodiments of the present utility model: Please refer specifically to the attached Figures 1-4, including an energy-saving cooling system 1, a waste heat recovery system 2, a data computer room 3, and an intelligent controller 7. A fan 4 is provided at the bottom of the data computer room 3. The energy-saving cooling system 1 includes a heat pipe system 101 and an air-conditioning system 102. The air inlet end of the fan 4 is connected to the air-conditioning system 102;

The heat pipe system 101 and the air-conditioning system 102 are both connected to the air-cooled evaporator two 106. The air-cooled evaporator one 201 is connected to the waste heat recovery system 2;

[0045] The waste heat recovery system 2 includes a water-cooled condenser 202, a compressor one 203, and an expansion valve one 204.

The connection mode of the air-cooled evaporator one 201 is as follows: its water outlet is connected to the compressor one 203, the other end of the compressor one 203 communicates with the water-cooled condenser 202, an expansion valve one 204 is provided between the evaporator and the condenser, the hot water return enters the hot water storage tank 8 after passing through the condenser, and the hot water storage tank 8 communicates with the heat supply pipe network.

[0046] The working principle of the present utility model is: Working principle: After the return air of the data center passes through the air filter 5, it first enters the waste heat recovery and utilization system for waste heat recovery and utilization, and then is cooled. The intelligent controller 7 switches to operate under the heat pipe system 101 or the air-conditioning system 102 according to the outdoor climate conditions. After the return air is cooled, it passes through the air filter 5 again and is sent into the data center, absorbs the heat of the data center and then enters the return air duct to complete the cycle.

[0047] Waste heat recovery and utilization system: The return air of the data center first passes through the air-cooled evaporator one 201 in the waste heat recovery system 2. The refrigerant in the air-cooled evaporator one 201 absorbs the waste heat of the data center and evaporates, and then is compressed into a high-temperature and high-pressure gaseous refrigerant by the compressor one 203. The gaseous refrigerant condenses and releases heat in the condenser, exchanges heat with the hot water return, and after throttling by the expansion valve one 204, the refrigerant returns to the air-cooled evaporator one 201 to complete the entire heat pump cycle. At the same time, the temperature of the hot water return rises and then enters the hot water storage tank 8, and the hot water storage tank 8 communicates with the heat supply pipe network.

[0048] Heat pipe system 101: When the cooling capacity provided by outdoor air can meet the data center's requirements, the heat pipe system 101 is used to cool the data center. Open the first shut-off valve 107, the fourth shut-off valve 110, and the heat-driven liquid pump, and close the second shut-off valve 108, the third shut-off valve 109, and the second compressor 103. The refrigerant in the air-cooled evaporator 106 absorbs the waste heat in the return air of the data center and evaporates, then reaches the air-cooled condenser 105 outdoors through the heat-driven liquid pump to release heat, and returns to the air-cooled evaporator 106 after releasing heat to complete the cycle.

[0049] Combined cooling mode: When outdoor air can provide cooling capacity but cannot fully meet the data center's requirements, the heat pipe system 101 and the air-conditioning system 102 are used in a combined cooling mode to cool the data center. Open the first shut-off valve 107, the fourth shut-off valve 110, the heat-driven liquid pump, the second shut-off valve 108, the third shut-off valve 109, and the second compressor 103. The refrigerant in the air-cooled evaporator 106 absorbs the waste heat in the return air of the data center and evaporates. Part of it reaches the air-cooled condenser 105 outdoors through the heat-driven liquid pump to release heat, and returns to the air-cooled evaporator 106 after releasing heat; the other part reaches the air-cooled condenser 105 outdoors through the second compressor 103 to release heat, and returns to the air-cooled evaporator 106 after throttling through the second expansion valve 111 to complete the cycle.

[0050] Air-conditioning system 102: When the outdoor temperature is too high to provide any cooling capacity for the data center, a fully mechanical refrigeration system is used to cool the data center. Open the second shut-off valve 108, the third shut-off valve 109, and the second compressor 103, and close the first shut-off valve 107, the fourth shut-off valve 110, and the heat-driven liquid pump. The return air of the data center that has passed through the waste heat recovery system reaches the air-cooled evaporator 106. The refrigerant in the evaporator absorbs the heat in the return air of the data center and evaporates, and then is compressed into a high-temperature and high-pressure gaseous refrigerant through the second compressor 103. The gaseous refrigerant condenses and releases heat in the outdoor air-cooled condenser 105, releasing the heat to the outdoor air. The condensed refrigerant returns to the evaporator after throttling through the second expansion valve 111 to complete the cycle.
