Abstract

This article
discusses the mathematical models of the individual structures and modes of
operation of a double-circuit solar collector with thermo siphon circulation.
To perform this task, we considered a new design of a flat solar collector with
thermo siphon circulation, in which the heat transfer coefficient was increased
by eliminating additional partitions between the panel and thermal insulation.
The efficiency of the solar collector is achieved due to the presence of the
metering tank and the heat pump in the tank, where the condenser and evaporator
are made in the form of a “spiral in a spiral” type heat exchanger, and the
heat exchanger pipelines are placed one above the other, which allows increasing
the area and intensity of heat exchange. The result of this work is a
theoretical and mathematical analysis of the unsteady thermal regime of flat
solar collectors on the modes of operation under consideration. Based on the
results of the analysis, it is possible to optimize individual structural
elements, as well as to predict the thermal regime and select alternative
solutions for the design of flat solar collectors and the choice of operating
modes.

Keywords
