Study on Hybrid Solar Energy and Ground-Source Heat Pump System

Aim at the weakness of more influenced by the environment etc. factor and the heat flow density lower when the solar energy was make use of heating, so the design method of the hybrid solar energy and ground-source heat pump is proposed, and the operating principle of this system has been studied. Thermal calculating methods of the solar energy collector and the ground-source heat pump was presented. Basing on a practical project, introduced the design methods and operating ways of this system. Experimental results prove that system heat coefficient of performance in winter averages 4.73 and system refrigeration coefficient of performance in summer averages 3.9, energy economy result very obvious, so this system very has research and expand value.
