High peak loads at transformer stations in domestic residences are expected where heating is provided merely by heat pumps with additional electric heating. Two scenarios are studied: the event of a black start and high electricity demand on a day with a very low outdoor temperature. The simulation is done with agents representing up to 100 dwellings based on PowerMatcher technology. The result...

induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

-Tree shade reduces summer air conditioning demand and increases winter heating load by intercepting solar energy that would otherwise heat the shaded structure. We evaluate the magnitude of these effects here for 254 residential properties participating in a utility sponsored tree planting program in Sacramento, California. Tree and building characteristics and typical weather data are used to...

Currently, strategies to mitigate urban heat island (UHI) effects and reduce building energy consumption are implemented worldwide. In Japan, as an effective means of mitigating UHI effects and saving energy of buildings, highly reflective (HR) roofs have increasingly been used. In this study, in order to evaluate the effect of HR roofs on building energy conservation, we investigated the solar...

Thermal storage is an essential concept within many energy systems. Such storage is generally used in order to smooth out the time lag between the acquisition and the use of energy, for example by using heat water tanks within heating systems. In this work we use a multi-agent system in order to maintain and operate distributed thermal storage among a large group of buildings in a district heat...

In this paper induction heating system is modeled and effective factors on induction heater system losses are represented. Respective to the intensive importance of capacitor losses and its potential ability of being harmful, furnace parameters must be designed in a way to minimize capacitor losses and maximize the transmitted power into the load. The effective parameters are the number of turn...

In this paper solar assisted heating and absorption cooling system and domestic hot water needs for a hotel having fifty rooms in Antalya have been investigated. First of all, solar radiation and meteorological data for Antalya and heating and cooling loads of the hotel building are given. For the heating cycle, active systems using liquid as the working fluid; and for the cooling cycle, solar-...

Development of effective heat treatments is crucial to achieve food products safety, and predictive microbiology is an excellent tool to design adequate processing conditions. This work focuses on the application of a modified Gompertz model to describe the inactivation behaviour under time-varying temperature conditions at the surface of a food product. Kinetic studies were carried out assumin...
