摘要
新疆某机场原采用2台7MW燃煤锅炉供热,由于不符合环保要求,需要采用清洁能源替代。根据该机场的供冷、供热需求,本文以地埋管地源热泵作为冷热源,燃气锅炉作为调峰热源,冷却塔作为辅助冷却装置,设计冷热联供系统,并分析该系统的技术经济。根据当地的电价和天然气价格,该系统总投资1040万元,年收益171.5万,静态投资回收期为6.1年。
An airport in Xinjiang originally used two 7MW coal-fired boilers for heating.Because it does not meet environmental protection requirements,it needs to be replaced by clean energy.According to the cooling and heating demand of the airport,the ground source heat pump is used as the cold and heat source,the gas boiler is used as the peaking heat source,the cooling tower is used as the auxiliary cooling device.Design a cold and heat supply system and analyze the technical economy of the system.According to the local electricity price and natural gas price,the total investment of the system is 10.4 million yuan,the annual income is 1.715 million,and the static investment recovery period is 6.1 years.
