Digital switched hydraulics

Min PAN, Andrew PLUMMER

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 2, Pages 225-231 doi: 10.1007/s11465-018-0509-7

Abstract:

This paper reviews recent developments in digital switched hydraulics particularly the switched inertance hydraulic systems (SIHSs). The performance of SIHSs is presented in brief with a discussion of several possible configurations and control strategies. The soft switching technology and high-speed switching valve design techniques are discussed. Challenges and recommendations are given based on the current research achievements.

Experimental investigation on desiccant air-conditioning system in India

Vijay MITTAL, B. Kant KHAN,

Frontiers in Energy 2010, Volume 4, Issue 2, Pages 161-165 doi: 10.1007/s11708-009-0070-5

Abstract: in a room with a volume of 86.4 m, air ducts and a blower.The experiment was made in such a way that the percentages of return air, outdoor air and indoor airmixed with the air leaving the desiccant and desiccant bed thickness could be adjusted.The optimum percentages of air ratios were as follows: 10% of outdoor air, 10% of return air (mixed togetherat the desiccant bed inlet) and 80% of indoor air mixed with the dry air leaving the desiccant.

API-based assessment on urban air environment bearing capability in China

Jinnan WANG,Jing ZHANG,Hongqiang JIANG,Yaling LU

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6, Pages 1049-1055 doi: 10.1007/s11783-014-0662-0

Abstract: Given the complexity and time-consuming of the conventional environmental capacity based assessment on airenvironment carrying capacity; a new method for assessing urban air environment carrying capacity basedon air pollution index (API) is presented.By using this new method, the air environmental bearing capability of 333 cities at the prefecture levelThe assessment results imply that the existing air quality standard (GB3095-1996) is quite unsound.
