TWO-CIRCUIT PUMPLESS SOLAR UNIT

摘要

Two-circuit pumpless solar unit has helio-collector, heat exchanger with tank for water heating and accumulator. All the elements of the unit are combined in one body and form two hydraulic circuits. In one of the circuits hot heat carrier recirculates, as water solution of ethylene-glycol ot glycerin, or usual water. And in the second circuit any neutral substance or water recirculates. Propulsive force of recirculation of both circuits is solar radiation.
