Application analysis of solar heat pump - floor radiant heating system in Northwest China

Characteristic and development situation of solar heat pump system are reviewed in this paper. It becomes an efficient and energy-saving heating system that combine the series non-direct expansion solar heat pump with floor radiant heating system together. The operation principle of solar heat pump-floor radiant heating system are described detailed. With the characteristic of abundant resource of solar energy in Northwest China, the feasibility of solar heat pump-floor radiant heating system applying in the Northwest China are analyzed, which demonstrates that the system is an ideal heating system with comfortable, economic and energy-saving.
