THE THERMAL MODEL OF A FLAT-PLATE SOLAR WATER-HEATING COLLECTOR
https://doi.org/10.15518/isjaee.2016.23-24.012-020
Abstract
The paper offers a thermal model to determine the specific heat productivity of flat-plate solar water-heating collector (FSWHC) depending of the pre-assigned temperature values of obtaining hot water. Unlike existing thermal models of FSWHC, for the first time in the proposed model the research results obtained by the authors are used to determine the average mass temperature of the heat-transfer (water) collectors, heat efficiency coefficient and the surface average working temperature of the light-absorbing heat-exchange panels (LAHP) by non-contact method, depending of the effective coefficient of LAHP heat losses. In order to determine the coefficient we have to take into account the partial absorption influence and conversion into heat of the total solar radiation passing through translucent cover of collector case and also the value of the LAHP surface average working and ambient temperature. It is provided a practical example of realization and proved authenticity of the model.
