高校集中浴室联合热水系统节能效益分析

Energy-saving Analysis of the Combined Hot Water System for Bathroom in University

根据青岛某高校浴室的运行现状,找出存在的问题。结合实际,分析了太阳能、空气源热泵、污水源热泵及辅助加热等联合热水系统作为该浴室热源的可行性。按照浴室的实际热水需求量及现场条件,计算各种热负荷,配备相关热水设备。通过对投资及运行经费进行测算,与原系统进行比较,发现联合热水系统的经济效益和环境效益明显,节能率可达66%,投资回收周期约为3.6年,具有较大的节能改造空间,将为今后节能改造提供比较可靠的技术支撑。

Existing problems of bathroom in a university in the integrated system with solar energy, air source heat pump, sewage heat pump and assisted heat sources is expounded. Based on the actual hot water requirement and site condition, the relevant equipment is provided after all kinds of thermal load calculation. It is found by calculation and comparison that the hot water system has better economic and environmental benefit and large energy-saving transformation space, the energy saving rate can reach 66%and the investment recovery period is about 3.6 years, which will supply a reliable technical support to subsequent energy saving reconstruction.
