ЗАСОБИ ВИМІРЮВАННЯ РАДІАЦІЙНОГО ТЕПЛООБМІНУ ТА ІНСОЛЯЦІЇ
Journal Title: World Science - Year 2018, Vol 5, Issue 7
Abstract
The article is aimed at reviewing the structure, technical characteristics and peculiarities of the use of instruments for measuring the intensity of radiation heat transfer and insolation, which were created at the Institute of Engineering Thermophysics of the NAS of Ukraine. The structure and basic components of calorimetric devices for measuring thermal radiation, which based on battery transducers of heat flow as sensitive elements, are considered. An absolute radiometer RAP-12SR with liquid cooling was created. It contains two identical cells - working receiver and reference. The output signals of cells are included in a differential scheme, which provides compensation for external non-informative influences. The quasidifferential receiver of the radiation heat flux RAP-12KD contains two cells with different sizes - the working cell with required size and a significantly smaller referent cell. The output signal of referent cell is amplified to the required level by hardware. Created multi-channel pyranometer CP-U1 is designed to determine the insolation, depending on the angle of inclination to the horizon. The pyranometer SR-M1 is intended for long-term monitoring of insolation of external elements of facades of investigated objects or surfaces, oriented on the sides of the world. The basic metrological characteristics of the developed devices and their structure are given.
