Design of solar water heating system for detached house in cold climate area

Abstract

Awareness of an environmental problem and high energy cost, people is interested in renewable energy. Solar energy is one of the renewable energy which it is the simplest and is easy to use. In this report, design method for solar water heating system in severe cold region at middle latitude is discussed. 1st: the measurement result of the solar water heating system combined with heat-pump system was introduced. 2nd: the results of the numerical analysis for the above system are introduced. 3rd: the solar water heating system for detached house in a cold climate area based on the above result was proposed. Also, the numerical analysis for the system is conducted. The result indicates multiple tank system is more efficient than single tank with thermal stratification.
