In the summer of 2010, we performed some on-site measurements to investigate the outdoor air temperature and wind velocity of Happy Homeland, a typical post-earthquake transition settlement of Sichuan. With the results of the measurements we found some problems in the existing planning and design of the settlements and proposed improvement which can make the transition settlements have larger volume fraction and better ventilation environment. The CFD simulation results show that the improvement can enhance the outdoor wind velocity by 19.4% and 16.7% respectively, and can raise the air changes per hour by 44.4% and 63.7% respectively, compared with the present condition.
The Low-Carbon economy enhances the use of renewable energy for indoor environmental control. River water could be a nice renewable energy as it can be used as a lowstand heat/cold source to control the indoor environment through Water Source Heat Pump (WSHP) units. However traditional WSHP units are not applicable because the high cost of water treatment to improve the present water property, and the advantages of the WSHP are badly restricted. To overcome the limits of the present WSHP units, we develop an integrated heat exchanger for which the river water or waste water can be effectively used as a cooling medium while heat exchange is keeping and the exchanger is being cleaning. The newly-developed heat exchanger can keep effective operation and well realize the energy saving.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
