海水乙二醇溶液换热器设计方案

海水—乙二醇溶液换热器的设计天津大学 俞洁，由世俊，张欢摘要 海水源热泵具有节能环保、运行稳定等特点，目前在沿海地区越来越受到关注。天津港30 万吨油码头办公楼采用海水源热泵采暖空调系统。由于海水的腐蚀性和海洋生物附着问题，工程中海水不直接进入热泵机组，而是采用中间换热器，使海水与来自热泵机组的乙二醇溶液在换热器中进行换热。天津港地处渤海湾，拥有丰富的海水资源，并且使用海水源热泵已经具有可靠的技术保障。本工程中换热器能很好的解决海水的腐蚀问题，清洗方便，换热效果好，这种高效经济的换热器，将非常有利于海水源热泵在我国沿海地区的推广应用。关键词 海水源热泵；换热器计算；防腐；阻力性能Abstract The sea-water source heat pump technology has been paid great attention to inthe coastal regions because of its energy-saving, environment protection and operationstability and so on. The sea-water source heat pump air conditioning system has beenused for the office building in TianjinPort’ s 300,000-ton oil dock. Considering theseawater corrosion and halobios adhesions, we adopt heat exchanger to transferbuilding heat or cold to seawater. The seawater doesn’ t go into the heat exchanger, butexchanges the energy with glycol liquor which comes from the heat pump unit.TianjinPort area is rich in seawater, and the use of seawater-source heat pumphas a reliable technical support. The heat exchanger can be a good intermediatesolution of the corrosion of sea water. It can be conveniently washed and has goodeffect of heat transfer.Todesign a kind of heat exchanger with the characteristic of high efficiency and greateconomic value will beneficially extent the sea-water source heat pump in ourcountry’ s littoral.1 前言随着我国沿海城市经济的不断发展，城市人民生活水平的提高，建筑能耗总量也逐年上升，其中用于空调系统的能耗在总建筑能耗中占有较高的比例，在一些高档公共建筑的全年能耗中，大约50%～60％消耗于空调制冷及采暖系统，故空调系统节能，意义...
