Improving solar-air source heat pump performance via heat grid

A scientific group has proposed adding thermal solar panels to air-source heat pumps while also using grid heating to keep temperatures stable at night. The group modeled a system that could reportely achieve a coefficient of performance of 10. 11 and represent an optimal solutions for cold climates. Researchers from China's Shenyang Jianzhu University have proposed a novel heating system for severe cold regions based on solar-air source heat pumps (SASHPs) and the support of the heat grid. The solar-air source heat pump coupled heating system based on the heat grid (NH-SASHP) uses the heat grid ...
