Practical Seawater Source Heat Pump Projects in China

Abstract

In China, it covers a sea area of about 4.73 million square kilometers, with a mainland coastline of about 18 thousand kilometers. Seawater is ideal as a heat source or sink of heat pump for heating or cooling and seawater source heat pump (SWHP) technology is a promising way to utilize ocean thermal energy. At present, SWHP has been well used in China. The article presents the application of SWHP in some cities, such as Dalian, Tianjin and Qingdao etc. Summary of these successful practical experiences of SWHP aims at informing the design for other similar projects.
