A great deal of heat is wasted in intensive public shower facilities, such as those in schools, barracks and natatoriums, which open up at specified time. It will contribute a lot to energy saving and environmental protection with significant economic benefits to recycle the exhaust heat. In...

A complete review of working fluids of absorption cycles is presented. Absorption cycles contain absorption heat pumps, absorption chillers and absorption transformers. Working fluids are divided into five series according to different absorbents.

A new waste heat district heating system with CHP based on ejector heat exchangers and absorption heat pumps (DH-EHE) is presented to decrease heating energy consumption of existing CHP systems by recovering waste heat of exhausted steam from a steam turbine, which could also increase heat...

Large district heating (DH) system accounts for 70% of urban building heating in China. In North China, this proportion is even higher (The North China is the north of the Huai River and Qinling Mountains). Many cities in North China can exploit various kinds of low-grade renewable energy. This...

In the district heating system, the AHE (Absorption Heat Exchanger) can transfer the heat of the primary network with a large temperature drop to the secondary network with a small temperature lift in a heating station. Triangular heat transfer processes exist in a traditional AHE, and limit the...
