System Design and Analysis of Heat Supply Using Waste Heat from Data Centers

Waste heat heating in data centers is an important way to improve the energy utilization efficiency of data centers and achieve clean heating in winter. This paper proposes a long-distance heating system for data centers, setting up a multi-stage heat pump at the heat source and heat sink to increase the temperature difference between the supply and return water of the heating pipeline network, and using a heat storage device to guarantee the safety of the data center and the heating system, and to improve the utilization rate of waste heat in the data center. A data center in Zhangjiakou was analyzed as an example, and the initial investment of the system is 50.21 yuan/m2, the operating cost is 26.37 yuan/GJ, and the payback period is about 5.31 a, which has better economy and energy saving and emission reduction effect.

Air conditioning heat pump dichotomous supply

To put it simply, the so-called “two-connected supply” is to use a set of air energy heat pump system to provide “hot water + heating” or “heating + cooling” two combinations of functions; The “triple-heating” is to provide “air conditioning + floor heating + hot water” three combinations of functions. The terms “two-connected supply” and “three-connected supply” generally refer to hot and cold water air-conditioning systems.
