SOLAR HEAT SUPPLY SYSTEM WITH CONTROLLED ABSORPTION CAPACITY Russian patent published in 2020 - IPC F24S90/00 

FIELD: heat exchange.

SUBSTANCE: invention relates to solar heat supply systems using solar energy and converting it into heat and can be used for heating and water supply of industrial and civil objects with hot water. Solar heat supply system includes a solar collector with a liquid heat carrier containing a dispersed phase with high light-absorbing properties, as well as a recuperative heat exchanger, pump and module for controlling concentration of disperse phase in liquid heat carrier, connected by system of pipelines to primary circulation circuit, wherein said module is configured to separate heat carrier into two streams, one of which comprises a dispersed phase in maximum concentration, and other - in minimum, is equipped with two outlet pipes with automatically controlled control valves, as well as automatic control system with temperature sensor. Said module can be in form of centrifugal separator, hydrodynamic or electrostatic separator, cleaning separator with gravity separation, filter, which performs separation under effect of pressure difference on filter element. An alternative to control valves can be represented by three-way valve.

EFFECT: technical result is higher stability of system due to elimination of causes of sedimentation instability of heat carrier with simultaneous expansion of range of control of absorption capacity of solar collector and heating capacity of system.
