A thermodynamics drinking fountain is presented in the artic.After city water is heated to 90℃ in order to disinfect and to become drinking water,the 92% of drinking water apparent heat is recovered through a closed heat circulation formed by 5℃ temperature difference heat transfer again to produce a thermodynamics drinking water that is only 5℃ higher than city water.Therefore increasing output and reducing power and thermodynamics drinking fountain function rich in oxygen are all realized,and the life-style of green drinking fountain will have be initiated.%本文提出一种热力直饮机,上水加热到90℃杀菌而成为饮水后,再通过5℃小温差换热所形成的闭路热焓循环,回收92%的饮水显热,制取仅比上水高5℃的热力直饮水,以实现增加产量、减少能耗、富含氧气的热力直饮机功能,倡导＂绿色直饮＂生活方式。
