随着学校的发展和教学条件提高,单一的燃煤锅炉供暖系统已无法满足冬季供热、夏季供冷的需求。本文基于Trnsys软件对可行的燃气(煤)锅炉/市政热力管网供热+冷水机组供冷、空气源热泵、地源热泵+太阳能蓄热三种冷热源方案进行模拟,从技术性、经济性、效益性三方面进行比较分析,最终得出最佳冷热源改造方案。 With the development of schools and the improvement of teaching conditions, a single coal-fired boiler heating system has been unable to meet the needs of heating in winter and cooling in summer. Based on the Trnsys software, this paper simulates the three schemes of cooling and heating, air source heat pump, ground source heat pump and solar heat storage for the heat supply of gas (coal) boiler / municipal heat pipe network + cold water unit, , Benefit comparative analysis of the three aspects, and ultimately come to the best cold and heat source transformation program.
