The Air Consumption Estimation of Convection Heaters with Natural Convection and Water Heat Carrier

Abstract:

The knowledge of temperature and air consumption at the output of a convection heater is required to develop an effective system protecting serviced room zones against descending cold air flow near the glassing. The existing method of heat appliances’ study and calculation, which uses an idea of nominal heat flow, does not provide those parameters. The analytic correlation between aerodynamical and thermotechnical characteristics of heat convectors with natural circulation at nominal conditions is established. The experimental estimation of air consumption and local resistance coefficient of „Atoll“ (PKN 309) convection heater is carried out. The obtained dependencies allow calculating temperature and air consumption at convection heater output by the existing method of heat appliances’ calculation using nominal heat flow.
