Joule’s first-law dictates that when electric current passes through a conductor heat is generated. The scope of this work to investigate the Joule heating effect two types carbon fiber tows in dry form. are used as primary elements on various preform structures require accurate and uniform temperature control, using DC power supply. investigated temperatures, ranged from 300 K up 650 K. A finite difference scheme was developed, order predict quantify transient phenomenon verified against...
The potential advantages of night-time heating greenhouses by modern infrared (IR) radiative sources, instead forced hot air, are examined experimentally and theoretically. Measurements indoor outdoor conditions during typical cold nights in central Greece were taken an experimental greenhouse using either air or IR heating. A simple theoretical model that contains all the essential physics was developed subsequently used parametric studies. Experimental simulation results confirmed that,...
Infrared (IR) heating as alternative to forced air has been studied experimentally for 70 days in two identical, small-scale, experimental greenhouses. The options were implemented with four IR electric lamps and an heater correspondingly. microclimate the greenhouses was monitored thermocouples. Parameters characterizing outdoors macroclimate also monitored. Lettuce used test crop, systems operated automatically maintain a suitable reference temperature at canopy. investigation focused on...
<abstract> <bold><sc>Abstract. </sc></bold>The advantages of Infra-Red (IR) heating is verified and demonstrated in a full-scale production greenhouse for vegetable seedlings, heated by gas-fired IR radiators. Temperature distributions data collected during 62-day period the winter showed that seedlings could be kept at optimum thermal conditions while air was maintained 2°C-3°C lower temperature, indicating significant reduction energy requirements. These results were also supported...
