an irreversible stirling heat pump cycle using ferromagnetic materials as a cyclic working substance is established. the influences of finite-rate heat transfer, heat leak, regeneration time, regenerative lossand the internal irreversibility on the cyclic performance of magnetic heat pumps are taken into account. on the basis of the thermodynamic properties of ferromagnetic materials, the perfo...

The mau requirements of arrcraft static tests are stated. The extent and effects of kinetx heating are described, and various methods of simulating and controlL.ng heatug In the laboratory are discussed. The further problem of kin&x cooling leads to the technique of heating and cooling by convection where the heating rate 1s low. Xecsurenents and test observations are d~s-cussed with reference ...

A moving metallic plate subject to heating and cooling boundary conditions is considered in this work. The plate is heated by an imposed heat  ux, and cooled down by an array of impinging jets through convection and radiation. The objective of the present work is determination of operating conditions for controlling the temperature distribution at the end of both heating and cooling sections. ...

This paper discusses the theory and experiments of heating and air cooling of battery modules. The heating mechanisms are shown first. Then, cooling of a single battery is examined. Optimum air flow speed is discussed. © 2014 The Authors. Published by Elsevier Ltd. Peer-review under responsibility of the Scientific Committee of IICST 2014.

Generally, polymers can be classified according to their thermal and mechanical properties into thermoplastics, thermosets and elastomers. Thermoplastics are amorphous or semicrystalline polymers that soft or melt during heating and solidify during cooling. The heating/cooling/heating process can be repeated without perceptible changes in thermal and mechanical properties of thermoplastics. The...

Heating, ventilating, and air-conditioning (HVAC) are parts of the major energy consumption in a building. Conventional heating and cooling systems are having an impact on carbon dioxide emissions, as well as on security of energy supply. In this regard, one of the attempts taken by researchers is the development of solar heating and cooling technologies. The objective of this paper is to revie...

Electronic devices composed of single molecules constitute the ultimate limit in the continued downscaling of electronic components. A key challenge for single-molecule electronics is to control the temperature of these junctions. Controlling heating and cooling effects in individual vibrational modes can, in principle, be utilized to increase stability of single-molecule junctions under bias, ...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

Thermal energy storage has received significant interest for delivering heating and cooling in both transportation and building sectors. It can minimize the use of on-board electric batteries for heating, ventilation and air-conditioning (HVAC) in electric vehicles (EVs) or reduce electricity consumption during peak demand in residential and commercial buildings. A compact and lightweight advan...
