多能互补型热源在浴室热水系统中的运行分析

Operation analysis of multi energy complementary heat source in bathroom hot water system

随着我国经济的发展,环境污染、能源短缺成为当前社会急需解决的问题。为响应国家节能减排的号召,现拟对沈阳某高校洗浴中心进行能源改造。因为洗浴污水温度大约30℃,而且高校中的公共浴室具有用水时间集中、洗浴污水量大的特点,直接排放会造成巨大的能源浪费,因此回收利用公共浴室污水中的低品位热能对节能、减排有促进作用。以沈阳某高校为例,本着设计合理、充分利用可再生能源,减少运行费用,节能环保的设计理念拟设计一套太阳能—污水源热泵复合系统代替其原有的燃气锅炉系统,并从经济效益及环保效益方面与原系统进行比较,分析其可行性。

With the development of China's economy,environmental pollution and energy shortage have become urgent problems to be solved in the current society.In response to the national call for energy conservation and emission reduction,it is planned to transform the energy of a bathing center of a university in Shenyang.Because the temperature of bathing sewage is about 30℃,and the public bathroom in colleges and universities has the characteristics of centralized water use time and large amount of bathing sewage,direct discharge will cause huge energy waste.Therefore,recycling the low-grade heat energy in public bathroom sewage can promote energy conservation and emission reduction.Taking a university in Shenyang as an example,based on the design concept of reasonable design,making full use of renewable energy,reducing operating costs,energy conservation and environmental protection,it is proposed to design a set of solar sewage source heat pump composite system to replace its original gas-fired boiler system,and compare it with the original system in terms of economic and environmental benefits to analyze its feasibility.
