In recent years,due to the transformation of social economy and the change of popu-lation structure in our country,a large number of buildings originally built have not met the needs of the market economy,and the transformation of existing old buildings has become an industry phenomenon.However,the design difficulty of the renovation project is often greater than that of the new project due to the inconsistency between the new and the old standards,the change of building positioning,function and separation,the need to connect the original system and other reasons.This paper analyzes and expounds the existing problems of the centralized hot water sys-tem in the original building,such as the complex system and large heat loss,through the renova-tion case of three high-rise residential buildings in a residential quarter in Sanya,Hainan province,The dual energy coupling hot water system with solar energy and air source heat pump as the heat source can not realize the coupling and other typical difficulties in transformation design,and pro-vides a series of solutions for these existing problems,such as reducing the heat source,simplify-ing and optimizing the system.After the renovation of the old building,it has been in good opera-tion.Through case analysis,this paper discusses the design ideas for the renovation of the hot wa-ter system of high-end hotel-style apartments.
