Example 1
The liquid cooling side cooling system comprises a liquid cooling tail end 1 of the data center, a first plate heat exchanger 5, a first cooling tower 7, a first water pump P1, a second water pump P2, a second valve V2, a fourth valve V4 and an eighth valve V8.
In this embodiment, the liquid cooling side cooling system operates throughout the year, and when the temperature of the liquid cooling terminal 1 is low or solar radiation is weak in the non-heating season, the liquid cooling terminal 1 outputs high-temperature cooling liquid, and the high-temperature cooling liquid is cooled by the adsorption refrigerator and then further cooled by the first plate heat exchanger 5, so that the low-temperature cooling liquid is sent to the liquid cooling terminal 1 to cool the data center IT equipment, and the temperature of cooling fluid in the first plate heat exchanger 5 is increased, and heat is discharged outdoors by the first cooling tower 7.
The data center liquid cooling terminal 1 generates high-temperature cooling liquid through the second valve V2, is cooled by an adsorption refrigerator and then is completely output to the first plate heat exchanger 5, the first plate heat exchanger 5 transfers the heat of the high-temperature cooling liquid to cold fluid through heat exchange, so that the cold fluid is heated, the temperature is increased, the temperature of the high-temperature cooling liquid is reduced and is sent to the liquid cooling terminal 1, then the cold fluid heat of the first plate heat exchanger 5 is exchanged with the outdoor air of the first cooling tower 7 through the fourth valve V4, the outdoor air absorbs the cold fluid heat to reduce the temperature, and then the cold fluid heat is sent to the first plate heat exchanger 5 through the eighth valve V8 through the adsorption refrigerator condenser 6, so that free cooling and waste heat cooling are realized.
Example 2
The liquid cooling side waste heat recovery cold producing system comprises a liquid cooling tail end 1 of a data center, a solar heat collector 3, an adsorption refrigerator, a first plate heat exchanger 5, a first cooling tower 7, a first water pump P1, a second water pump P2, a third water pump P3, a first valve V1, a fourth valve V4 and an eighth valve V8.
In this embodiment, heat generated by the CPU, GPU, etc. in the data center electronics can be cooled by the liquid cooled terminal 1. The temperature of the cooling liquid in the liquid cooling tail end 1 can be correspondingly increased to form high-temperature cooling liquid after absorbing heat, and the formed high-temperature cooling liquid is output from a high-temperature cooling liquid output end of the data center, so that each electronic device of the data center is cooled. It can be appreciated that the liquid cooling terminal can be disposed near the GPU, CPU, etc. in the electronic device, so that the liquid cooling effect is better. The cold system of the cold side waste heat recovery of the data center can recover the heat of the high-temperature cooling liquid output by the data center, in order to enable the adsorption type refrigerator to operate efficiently, the output high-temperature cooling liquid is output to the solar heat collector 3, the solar heat collector 3 further increases the temperature of the high-temperature cooling liquid to be within the high-efficiency temperature range (70-95 ℃) of the operation of the adsorption type refrigerator, the adsorption type refrigerator absorbs the heat of the high-temperature cooling liquid to prepare low-temperature cooling liquid, the low-temperature cooling liquid is used for cooling electronic equipment at the tail end of the liquid cooling of the data center, if the low-temperature cooling liquid does not reach the upper limit temperature of the tail end of the liquid cooling, the first cooling tower 7 is required to cool again at the moment, then the low-temperature cooling liquid is sent to the tail end of the liquid cooling to cool the electronic equipment, meanwhile, the adsorption type refrigerator generates low-temperature chilled water, the low-temperature chilled water can provide partial cold capacity for the tail end of the air cooling of the data center, the liquid cooling liquid can more effectively take away 20% -35% of the heat of the data center, and the low-temperature cooling liquid still needs to be cooled by the tail end of the air cooling air, and the cold cannot be completely carried out by the cold cooling heat of the cold cooling tail end of the liquid.
Specifically, in the working process of the cold system of the cold side waste heat recovery of the data center liquid, when solar radiation is strong in daytime in a non-heating season, the first valve V1 is opened, the second valve V2 and the third valve V3 are closed, the high-temperature cooling liquid generated at the tail end of the liquid cooling of the data center is output to the water inlet end of the solar heat collector 3, the solar heat collector 3 further improves the temperature of the high-temperature cooling liquid and then outputs the high-temperature cooling liquid to the first adsorber 4 of the adsorption refrigerator, the first adsorber 4 absorbs the heat of the high-temperature cooling liquid, and refrigerating water generated after adsorption refrigeration circulation is transmitted to the precise air conditioner 13. The condensation heat generated by the adsorption refrigeration cycle is released to cooling water through a condenser 6, the cooling water is heated after absorbing heat through the condenser, and then is heated further after absorbing heat through a plate heat exchanger 5, and then is cooled in a first cooling tower 7. In general, the high-temperature cooling liquid is insufficient to meet the liquid cooling temperature after entering the adsorption refrigerator for cooling, and heat exchange is required to be performed between the high-temperature cooling liquid and the cold fluid through the first plate heat exchanger 5. The fourth valve V4 is opened, the seventh valve V7 is closed, the eighth valve V8 is opened, and the heat of the cooling water in the condenser of the adsorption refrigerator is firstly subjected to heat exchange with the outdoor air through the first plate heat exchanger 5 and then is discharged to the outside through the first cooling tower 7. When the solar radiation is weaker or at night in a non-heating season, the solar heat collector 3 is closed, the adsorption refrigerator is still started, the liquid cooling side cooling liquid is cooled by the adsorption refrigerator, and then is further cooled by heat exchange between the first plate heat exchanger 5 and the first cooling tower 7 and then is sent to the liquid cooling tail end. Therefore, the heat dissipation of the data center is achieved, the self-sufficiency is achieved, the cooling capacity is provided for the air cooling side of the data center, the power consumption is reduced, the PUE of the data center is reduced, and the energy utilization rate is improved.
