The coupled climate dynamics underlying large, rapid, and potentially irreversible changes in ice cover are studied. A global atmosphere–ocean–sea ice general circulation model with idealized aquaplanet geometry is forced by gradual multi-millennial variations in solar luminosity. The model traverses a hysteresis loop between warm ice-free conditions and cold glacial conditions in response to 6...

Higher-efficiency HVAC filters generally have a higher pressure drop and are widely assumed to increase energy consumption in smaller air conditioning systems. To explore the effects of filters in real buildings, we monitored 17 residential and light-commercial forced air cooling systems in Austin, TX. Measurements were made once per month for one year at each site with filters from three diffe...

A retrofit study is being conducted to investigate the airtightness, ventilation and energy impacts of tightening the exterior envelope and the heating and air conditioning system ductwork of a double section manufactured house. This report describes the results of the pre-retrofit assessment of building airtightness, ventilation, and energy consumption under both heating and cooling conditions...

Background information as to the environmental effect of discharges of mercury is provided. The information has justified a programme, outlined in the paper, for reducing mercury in products, waste waters and vented air from chlorine plants using the mercury process. The strict separation of the waste waters and certain technical measures creates possibilities of reducing the discharges effecti...

The power dissipation levels in high performance personal computers continue to increase rapidly while the silicon die temperature requirements remain unchanged or have been lowered. Advanced air cooling solutions for the major heat sources such as CPU and GPU modules use heat pipes and high flow rate fans to manage the heat load at the expense of significant increases in the sound power emitte...

The causes of decadal variations of North Pacific sea surface temperatures (SSTs) are examined using a hindcast performed with an ocean general circulation model thermodynamically coupled to an atmospheric mixed layer model (OGCM–AML model) and forced by the time history of observed surface winds. The ‘‘shift’’ in North Pacific Ocean climate that occurred around 1976/77 is focused on since this...

The article describes a mathematical model of interconnected electromechanical and thermal processes in linear induction motor (LIM). Here, we present the structure provide calculation formulas model. consisted eight control volumes on each tooth pitch LIM. Moreover, also its interaction with was based detailed magnetic electrical equivalent circuits Model verification performed using finite el...

In this work, CFD is used to simulate the flow in an existing thermal labyrinth located at the basement of a hospital building. This labyrinth is an underground channel equipped with water tanks to increase the thermal mass and reduce the heating and cooling demand of the building. Thermal energy storage in the water tanks is a complex heat transfer phenomena involving turbulent forced convecti...

A promising type of green transport, lithium battery-powered electric cars (EVs) have attracted a lot attention and interest in the current years. In this study, thermoelectric cooling with forced convection was designed possible method for thermal control battery system. Compared to free cooling, air TEC appear is leading work. Conditional tests are done on created system EV automobile vehicle...
