Research And Analysis Of Solar Heat Pump Performance
Abstract
Solar energy is a kind of inexhaustible, clean energy and the heat pump has high efficiency in energy utilization. If solar energy and heat pumps are combined and developed into a solar heat pump system, it will produce greater economic and social benefits. This experiment develops and designs three different solar heat pump water heater systems: solar direct-expansion heat pump water heater, solar and air dual-source heat pump water heater, and PVT heat pump water heater. Moreover, the performance of three kinds of solar heat pump water heater systems is preliminarily tested and verified under different solar irradiation. The problems found in the testing process are analyzed and demonstrated, which lays a foundation for the future commercial development of solar heat pump water heater systems.
