摘要：

A plan for retrofitting the solar energy & oil water heating systems into solar & heat pump water heating systems in a campus in Shenzhen, China, is put forward to save energy. Results of selecting equipments and operation control are introduced in details, and the economic analysis about the retrofitting plan is mentioned in briefly in this paper. It shows that with retaining the original solar energy water heating systems, the water heating systems are more suitable for environmental protection, and its operation control are more reasonable and efficient if the original oil boilers are replaced by air-source heat pumps. Calculations show that after retrofitting, the saved annual operation cost will be RMB956900.00 the energy saving ratio may be 56.3% and the initial investment can be paid back in 2 years.
