Abstract：The system which is used for heating swimming pool water is designed. It joint solar energy and ground source heat pump and has the advantage of saving energy and environmental protection.
The swimming pool is heated mainly by solar energy and auxiliarily by ground source heat pump. The collectors are made of vacuum tubes. The advantages of this kind collector are of high heat collecting rate and structural strong. The ground heat exchanger is vertically set and easily installed. This system can run under the constant temperature, can protect from high and low temperature. This design includes choosing equipments and economical analysis.
