One of the important issues of energy policy the EU and Ukraine is the economical use of energy. An effective way to provide temperature conditions in production facilities is the use of infrared heaters. The main advantage of them is that they heat only the areas where heating is required. The purpose of the publication was mathematical modeling of heat regime formation in the irradiation area of...
The aim of the article is to establish the necessary air exchange rate in the room at the principe production carbon dioxide calculation and experiment. There was calculated CO2 produced by humans in the room. Ventilation rate was calculated by several methods and compared with the measured carbon dioxide production.
The main causes of human heat loss are convection, conduction, radiation and evaporation. Conductive heat loss is so small that it can be considered alongside convective heat loss. The most characteristic factor of heat loss is radiation. As a result of experimental studies, a graph of air temperature in the work area was plotted showing the mobility of air at different heat capacities of the emitter...
The paper presents the research result of the settlements of temperatures in characteristic points in greenhouses with thermal screen. Investigations were made for free-standing greenhouses with different properties of additional screen.
