Mathematical Substantiation Of Principal Parameters Of Thermosiphon Effect For Solar Heating

An article hereby considers the thermosyphon circulation solar collector main parameters for the solar heat supply system. To fulfill the given task there has been stipulated a new thermosyphon circulation flat solar collector's construction having been developed by us, in which the thermal transmission coefficient has been increased at the expense of removing the additional partitions between a panel and heat insulation. Being considered solar collector's efficiency is reached owing to the availability of a tank-dozer and thermal pump in the construction herein, where a condenser and evaporator have been executed in the form of a heat-exchanger of "spiral in spiral" type, and heat exchangers pipe connections are laid one above another, which allows increasing the square and heat exchange intensity. Outcome of the work herein is description of the mathematical analysis of the heat transmission process in the tank-accumulator jointly with the initial and boundary conditions. We have shown a heat carrier thermophysical parameters dependence on the temperature, which is shown with equations. We have solved the equation of a heat carrier motion along the base-collector circuit line under the thermosyphon effect influence.
