This paper presents the preliminary modelling perspectives of an ongoing project where a flexible simulation tool for component and system analysis of district heating consumer installations is developed. The simulation tool makes it possible to simulate district heating consumer installations containing water based central heating systems, domestic hot tap water systems, buildings as well as l...

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...

temperature and humidity are two important parameters affecting the quality and quantity of greenhouse products so two double greenhouses were manufactured in 3.5, 40 and 11 m in height, length and width respectively in agricultural research center of jiroft and kahnooj to study these effects. both of greenhouses are similar in materials, final height, gutter height, covering and field operatio...

in this study, a numerical simulation using the cfd software, fluent, has been conducted to examine the effect of various shapes of the venturi component sections in order to find the optimum venturi specifications to increase the egr rate with minimum pressure loss at the part load operation range. the cfd results reveal that the venturi should be precisely optimized to introduce the required ...

This paper describes fundamental characteristics of high frequency induction heating applied for Marine Fuel Oil (MFO) recovery system. The system is analyzed for an induction-heating load, related to operating frequency and input power. Frequency domain characteristics of load equivalent circuit parameters in induction heating are investigated to clarify an effective circuit design of the high...

NCSX has been designed to accommodate a variety of heating systems, including ohmic heating, neutral beam injection, and RF. Neutral beams will provide one of the primary heating methods for NCSX. In addition to plasma heating, neutral beams are also expected to provide a means for external control over the level of toroidal plasma rotation velocity and its profile. The experimental plan requir...

The space heating in residential buildings accounts for a considerable amount of the primary energy use. Therefore, understanding the operation and performance of space heating systems becomes crucial in improving occupant comfort while reducing energy use. This study investigated the behavior of occupants adjusting their thermostat settings and heating system operations in a 62-unit affordable...

In low-heating-energy buildings heat pumps have become an attractive heating system due to a notable reduction of the space heating requirements and the introduction of low temperature heating systems. Comfort cooling becomes also more important, especially in lightweight buildings with large south-oriented windows, which partially tend to overheat in summer. A heat pump has the unique feature ...

This position paper provides qualitative considerations on the design and implementation of a smart heating control system for private households. We envision the system to rely on the opportunistic exploitation of information made available by existing smart devices. Since heating represents the major source of energy consumption in domestic environments, significant energy savings may be achi...
