Heating system design for National Hongqi Primary School in Yushu area, Qinghai Province

In the light of the engineering characteristics and climate conditions, the project adopts the heating system of solar energy plus low temperature type air-source heat pump. Presents the design of the system and its control requirements. The system adopts passive heating mode to satisfy the demand for heating during abundant sunshine periods and active heating mode during the other periods. In areas with abundant sunshine, using the solar energy and heat pump heating system reasonably and effectively can save system operation costs and reduce environment pollution caused by burning fossil fuels.
