In buildings, occupant behaviour is recognised as a major contributing factor to energy demand and in particular to heating consumption. To achieve thermal comfort within the heating season, people report to use heat in very different ways; for example behaviours include switching on the heating system, putting on warm clothes, drawing curtains, changing rooms, making a hot drink and using a ho...

The use of a minimum quantity of lubrication (MQL) with extremely low consumption of lubricant in machining processes has been reported as a technologically and environmentally feasible alternative to conventional flood cooling. In hot machining, the external heat source is applied during machining that will assist to increase machining performance. Many external heating techniques are availabl...

This study explored the application of radio frequency (RF) energy in conjunctionwith conventional hot air treatment to provide uniformheating for control ofmold in pre-packaged bread loaf. A 6 kW, 27.12 MHzRF system was...

the mode of heat and mass transfer during baking of bakery products is an important factor determining the quality of the final product. the heating rate could alter the starch properties during gelatinization and affect the quality of products after baking and during aging. sangak is a kind of iranian flat bread baked on the hot pebble gravels. the aim of this study was to evaluate the impacts...

In this study, thermal behavior of aqueous solutions of methyl cellulose (MC) at a constant temperature of 50 degrees C was analyzed. Various samples were studied for two consecutive heating-cooling cycles. The experiments with the solutions prepared using cold de-ionized (DI) water showed that the rate of gelation was higher for higher MC concentrations. However, the rate was slower during the...

The energy saving is becoming an important topic also in the food industry. For this reason, it is important to use multi-energy systems to produce hot water for processes and space heating. The application considered in this paper, which concerns a chocolate factory, focuses on the hot water production through a multi-source storage tank. The water inside the tank is heated by four solar panel...

This article describes the use of a newly invented compound stick gun to take impressions for complete denture. The border molding process involves loading the modeling compound in an electric heating device and applying an even thickness of compound on the flange of a custom tray at a proper temperature without hot water tempering. This method provides a quicker and easier border molding proce...

2014 The present paper reviews the problem of short term thermal energy storage for low temperature solar heating applications. The techniques of sensible and latent heat storage are discussed, with particular emphasis on the latter. Requirements for hot water storage subsystems are provided and the importance of stratification in hot water storage tanks is described. Concerning latent heat sto...

INTRODUCTION Water quality is a frequently overlooked issue in the application of geothermal heat pump (GHP) systems. When considered at all, is often viewed as a problem unique to open loop systems. In residential open loop applications water is supplied directly to the heat pump’s refrigerant-to-water heat exchanger. If the water has a tendency to be scale forming, fouling of the heat exchang...
