To investigate the status quo of heating supply and the impact of energy saving policies in northern China, a survey was conducted on the DHSs (district heating systems) in 15 Chinese cities. The average heating energy consumption was 19.2% lower than in 2008 due to the corresponding policies...

Jet impingement has been verified as an effective method to enhance convective heat transfer. To make better use of this effect, vacuum glazed transpired solar collector with slit-like perforations is developed. In this paper, a mathematical model based on energy balance equations for the solar...

Seawater-source heat pump systems (SWHP) are recognized to be outstanding heating, cooling and water heating systems. A large number of SWHP systems have been used in residential and commercial buildings in coastal areas due to the attractive advantages of high efficiency and environmental...
