Experimental determination of the air exchange system influence on the thermal conditions of a local working area heated by a gas infrared heater

Abstract

Abstract The paper describes the results of experimental studies to determine thermal conditions of the local working area under natural and mixed convection states during the operation of a gas infrared heater (GIH). A horizontal panel and a mock-up with a uniform imitating a table and a worker were located in the area of GIH influence. The values of temperatures and heat flux density of the panel surfaces and air around the worker model were obtained during the GIH operation under natural and mixed convection states. It was established that the presence of the forced component of convection practically does not change the thermal conditions of the local working area.
