COUPLING CHARACTERISTICS OF A SOLAR-AIR COMPOSITE HEAT SOURCE HEAT PUMP SYSTEM

摘要

Consider the advantages and disadvantages of single air source heat pump, single solar heat pump and switch solar and air dual heat source heat pump, a new type of solar-air composite heat source heat pump system(SACHP) was proposed, and it can realize the utilization and complementary advantages of two renewable energy: air and solar. The non-homomorphisms double heat sources heat exchanger was the core component of the composite heat pump. The heat exchanger had dual function of tube fin and tube heat exchangers, break through the traditional mode that heat exchanger in working can realize heat exchange only between the same gases or liquid heat sources, and realized the heat exchange between two non-homomorphisms heat sources. It laid the technological and equipmental foundation for realizing the synchronization and composite using of solar energy and air.
