Residential and commercial sectors are the main consumers of energy. According to available data, these two sectors account for more than one-third of total energy use. Moreover, heating and cooling systems contribute to the major share of energy use in a building. The current research economically evaluates the radio-frequency heating systems for use in residential buildings. A building in Dis...

Codling moth (Cydia pomonella [L.]), navel orangeworm (Amyelois transitella [Walker]), and Indianmeal moth (Plodia interpunctella [Hübner]) are common insect pests in walnuts (Juglans regia [L.]). Currently, exported in-shell walnuts are disinfested using methyl bromide fumigation. Restrictions on methyl bromide use have increased interest in developing alternative postharvest treatments. Radio...

A study was conducted with a pilot-scale sterilization system based on 27-MHz radio frequency (RF) energy to investigate the effectiveness in shortening process time and in improving quality for foods sealed in 6pound military-ration polymeric trays. Chemical marker M-1 was used to evaluate heating uniformity in 20% whey protein gels as a model food, and macaroni and cheese was processed to ass...

[1] Here we present electron temperature variations observed with incoherent scatter radar during a European Incoherent Scatter Scientific Association Heating experiment with high‐frequency (HF) radio wave transmission at frequencies above the peak ionospheric critical frequency. The electron temperature increased from 2000 K up to 2800 K during the HF transmission periods. During the experimen...

Piyasena, P. and Dussault, C. 2003. Continuous radio-frequency heating of a model viscous solution: Influence of active current, flow rate, and salt content on temperature rise. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 45: 3.273.34. Radio frequency can induce molecular friction in food products resulting in an internal heating effect; therefore, better heating of sensi...
