Executive Summary Growing concern over global climate change has triggered a search for methods to reduce overall carbon dioxide emissions. Reducing emissions from the heating and cooling systems of the 70 plus million single family North American residential units would assist significantly in this effort. However, given the current financial strains on homeowners, it is essential to find the ...
Rotational Doppler cooling and heating are generalized from their translational counterparts, revealing dissimilar physics.
Since the energy consumption has become one of the crisis of modern buildings, modeling the Iranian past architecture patterns could be helpful. The shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. However, using passive techniques, the Iranian traditional bazaars architecture solved the problems regard...
introduction: current thermal cycling units fail to simulate the drinking behaviors, and oral balancing temperature. they cannot also simulate other oral conditions such as drink coloring, and chemicals like tea, coffee, carbonated and noncarbonated, citrus juices as well as alcoholic and nonalcoholic drinks and also saliva and milk itself. the main objective of this study is to introduce the d...
A possible inconsistency when a radiative cooling term is incorporated in a finite resolution self-gravitating hydrodynamic code is discussed. The inconsistency appears when the heating-cooling balance within the cooling and collapsing gas cloud is broken near the resolution limit of a numerical code. As the result, the cooling time of a fluid element increases enormously leading to the unphysi...
Buildings play an important role in the energy demand sector. Due to the increase of environmentalconcerns and renewable energy sources restriction, lighting control systems will play an important role in the reductionof energy consumption of the lighting without impeding comfort goals. Lighting control systems can control lightingconsumption according to the type of building, adequate luminanc...
This paper reports a comparison of models for estimating the return time from a night setback condition. Fifty-seven models are compared using simulation data that include the influence of climate, building mass, controller tuning, room orientation, and the unoccupied control strategy on return time. Two-parameter models are recommended for estimating the return time for both heating and coolin...
A significant step in the design of Heating, Ventilating, Air Conditioning, and Refrigeration (HVAC-R) systems is to calculate the room thermal loads which often vary dynamically. A self-adjusting method is proposed for real-time calculation of heating/cooling loads in HVAC-R applications. In this method, the heat balance calculations are improved by realtime temperature data to achieve more ac...
