The energy conservation potential of the heat pipe based heat exchangers (HPHXs) was studied in this research. To this end, a typical climate chamber as the representative of an air conditioning system was established. The performance characteristic of a typical eight-row HPHX was obtained based on the one week operation (168 h) to determine the performance characteristic curves. The coil face ...

Although there are numerous possibilities to save energy, conservation initiatives often do not tailor their content to the consumer. By considering energy conservation as a one-dimensional construct, where different behaviors have different execution difficulties, we have set out a Rasch-based energy recommender system that provides tailored conservation advice to its users. Through an online ...

i n addition to labor force and capital, energy plays a significant role in the production of commodities and services. energy is the driving force of production activities. therefore, it is an essential ingredient of growth and development. results obtained from this paper show that the growth of oil products consumption has a positive effect on economic development via two channels: firstly, ...

Energy audit is an important factor that enables the energy management programmer of any firm for controlling its costs. The Scenario storage compelling adoption conservation measure describes less same level activity. basically controls cost and increase efficiency. in business practice gaining continuous attention due to vital role. This paper presents our motives identifying efficiency by pr...

Abstract In order to study energy consumption in Iran's agricultural sector, a Genetic algorithm concept was used to calculate significant factors affecting energy consumption between 1974 and 2008. Then, durability or "stability" of variables was assessed through econometric method (Augmented Dickey-Fuller test). In addition, long-term and short-term relationships of energy consumption were es...

A wireless ad-hoc network is a collection of mobile nodes that makes a multi hop autonomous system without any fixed infrastructure. The nodes use service of other nodes in the network to transmit packet to the destination nodes. Mobile device are battery operated and this is the limited resource. So the energy conservation is the critical issue in the network. There are many approach suggested...

In solving physics problems, it is often important to use the laws of conservation of energy and momentum. While most people have intuitive understanding of energy and of its conservation, there is usually no intuition behind momentum, and known textbook derivations of conservation of momentum use calculus – which is usually taught after momentum. In this paper, we show how the law of conservat...
