Energy efficiency reformation for an existing building in Hangzhou

Presents the reformation of the building envelope, water supply and drainage system, electricity automatic control system and air conditioning system. For energy efficiency reformation demonstration, this project adopts the ground-source heat pump system, temperature and humidity independent control system, water-cooled VRF and air-cooled VRF systems for comparing their operating data. Proffers the operating data of the air conditioning system in summer and analyses the problems found, providing a reference for similar reformation projects.
