海水源热泵的探讨(Discussion on sea water source heat pump) Discussion on sea water source heat pump 1. the concept and working principle of sea water source heat pump The sea water source heat pump technology is the use of shallow water in the earths surface (SEA) of low temperature heat resources to absorb solar energy and geothermal energy and the formation, and the use of heat pump principle by a small amount of high energy input, a kind of technology of low heat transfer to high heat. Sea water absorbs the considerable radiant energy of the sun entering the earth, and the temperature of the sea is generally stable. The working principle of seawater source heat pump unit is using seawater as the basic source extraction and storage of energy , it means the compressor system, consume a small amount of electrical energy, save in sea water of low grade energy take out in the winter to heat buildings in summer; put inside the building energy release to take out in the sea, in order to achieve the purpose of regulating indoor temperature. The biggest advantage of this unit is the efficient use of resources, firstly, although it uses seawater as a source, but does not consume water, not water pollution; secondly, its high thermal efficiency, consumed 1 kilowatts of electricity, you can get 3 to 4 kilowatts of heat or cold, fundamentally to change the traditional way of using energy. As shown in figure 1. 2. research status and development trend at home and abroad There are many examples of using sea water as heat and cold sources in foreign countries. As of early 1970s completion of the Sydney Opera House, Osaka Nanko Cosmo square at the beginning of the 1990s, Japan built regional heating cooling engineering, provide heat source for 23300kW heat pump using seawater. The Nordic countries have rich experience in the use of sea water heat sources, of which Sweden is a typical application of sea water source heat pump centralized cold / warm country.
