Entropic Efficiency of Energy Systems
-Thermodynamic foundations of the thermal entropy production are rested on the concept of lost heat, (Q/T)6T. The thermomechanical entropy production is shown to be in terms of the lost heat and the lost work as
متن کاملEnergy Efficiency of Refrigeration Systems
Energy efficiency plays an important role in the development and operation of refrigeration systems. The method of the VDMA 24247-2 2 “Energy efficiency of refrigeration systems – Requirements for the system design and the components” were recently published. The method will be described within this paper, with the focus on the graphical interpretation.
متن کاملEnergy Efficiency of MIMO systems
A multiple-input multiple-output (MIMO) system consists of multiple antennas at the receiver and transmitter. These multiple antennas can be used to improve the performance of the system through spatial diversity or increase the data rates by spatial multiplexing. One can also use some of the antennas for diversity and some for spatial multiplexing. The number used for diversity and spatial mul...
متن کاملEnergy Efficiency in Hpc Systems
1.1 INTRODUCTION Power consumption of High Performance Computing (HPC) platforms is becoming a major concern for a number of reasons including cost, reliability, energy conservation, and environmental impact. High-end HPC systems today consume several megawatts of power, enough to power small towns, and are in fact, soon approaching the limits of the power available to them. For example, the Cr...
متن کاملInvestigation of Energy Efficiency of Broiler Farms in Different Capacity Management Systems
An experiment was performed to investigate the energy efficiency and effect of poultry house size on energy productivity in 3 different capacity management systems. Capacities of houses were 10000(3 housings), 20000 (2 housings) and 28000 (1 housing) birds per production period and were assigned as HI, HII and HIII respectively. This experiment was conducted in a completely randomized design ap...
