NO PRESSURE THERMAL SOLAR SYSTEM WITH HEAT STORAGE

FOR RESIDENTIAL HOUSE SPACE HEATING

Solar heater is made of parallel rows of transparent glass

tubes. Each tube contains a glass outer tube and metal

absorber tube attached to a fin. The fin is covered with a

coating that absorbs well solar energy, but which inhibits

radiative heat loss. Air is removed from the space between the

glass tubes and the metal tubes to form a vacuum, which

eliminates conductive and convective heat loss. A well-

insulated storage tank stores hot water. The system uses a

pump to circulate household water through the collectors and

into the home.

The three-phase brushless motor has three stator windings

connected in delta and comes complete with hall effect

sensors that provide information on the position of the rotor.

This type of motor has excellent torque characteristics, low

inertia and possibility of strictly constant speed. For operation

it is necessary to add only a stabilized power supply 30 V - 5 A,

the kit comes complete with knobs, switches and cables.
