4 articles for “net saving”

Research ArticleOpen accessIn the keywordsThe Thermo-Economics Analysis of the Optimum Thickness of Double-Layer Insulation for Air Conditioning DuctN. Soponpongpipat, P. Jaruyanon, S. NanetoeProblem statement: Engineering economics played an important role in engineering design works. The net saving value was the easiest criterion to indicate the optimum design. However, the information about the net saving analysis of double-layer insulation of air conditioning duct was insufficient. Thus, it was important to study this case. Approach: The optimum thickness analysis of air conditioning duct’s insulation, … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,722 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiological Peculiarities of Archips rosana, the Insect Pest of the Sievers Apple Tree (Malus sieversii) in the Trans-Ili Alatau Ridge (the North Tien Shan)Gulzhanat Tanabekova, Roman Jashenko, Zhaozhi LuThe article provides new information on the phenology of a serious insect pest, the species of Archips rosana (Linnaeus, 1758) (Lepidoptera: Tortricidae), rendering fundamental harm to the Sievers apple trees, native to the Trans-Ili Alatau region (the North Tian Shan), which was not previously covered by studies. Material for research was obtained by the authors during two field seasons 2018-2019 … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 23 Nov 2020 · 6,551 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Cross-Layered Path Stability Based Routing Protocol for WiMAX NetworksM. Deva Priya, M. L. ValarmathiIn IEEE 802.16, a Subscriber Station (SS) is battery powered with limited capacity. A SS can be made to operate for longer durations by deploying power saving features or by using relay stations. Multi-hop communication conserves power, but finding an optimal path to the destination is monotonous. Path stability indicates how stable a path is and how long it can … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 6,673 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMathematical Model of the Optimum Heat Pipe Heat Exchanger for a Condenser of Vapor-Compression Refrigeration CycleP. Yeunyongkul, P. Sakulchangsatjatai, P. TerdtoonProblem statement: This study theoretically investigated applying heat pipe as a heat exchanger in the condenser of vapor compression refrigeration system for sustainable well-being. Split-type air conditioner for residential propose was considered. To reduce pressure drop and recover heat from the condensing process of the refrigeration cycle, this investigation tried to use Closed Loop Oscillating Heat Pipe (CLOHP) instead of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,631 accessesView PDF Cite
