SU114537A1 - Condensation Radiation Balance Integrator - Google Patents

Description

The proposed condensation integrator of radiation balance is of a known type of purpose devices with two concomitant vessels forming radiation receivers with external vacuum thermal insulation, one of the walls of which is blackened open for radiation, and a certain amount of easily evaporated liquid is poured into the vessels.

Such integrators do not provide the required measurement accuracy due to poor contact of the blackened receiving surface with a volatile liquid, deviations from the cosine law, the lack of a common thermal insulation casing, significant dependence of their readings on wind speed and condensation under certain conditions of atmospheric moisture on the blackened receiving surface.

The peculiarity of the proposed condensation integrator, which provides an increase in the measurement accuracy, is the spherical shape of the vessels with receiving openings and double walls, the inside of which is made transparent and on the side facing the outer wall is covered with a layer of black hygroscopic substance.

In the drawing, the proposed integrator is shown in transverse and longitudinal sections.

The radiation receiver is two spherical chambers 1 and 2 ,. facing the same diameter with receiving holes in opposite directions. The chambers / and 2 have double walls 3 and 4, the cavities between which are connected by tube 5 and are connected to measuring: tubes 6 with a common scale of 7, scaled to the values of the radiation balance. In the cavity between the walls 3 to 4, a certain amount of volatile liquid — ether — is poured to fill the entire system with vapor of this liquid. Walls 3 are made of a substance reflecting radiation, and walls 4 are made of glass and on the side facing

wall 3, covered with a layer of black hygroscopic substance, shown in dotted lines. On the walls 4 there are conic extensions 8, immersed in the production of measurements in a liquid for reliable wetting of the hygroscopic suspension, and serving for draining the liquid in the measuring tubes 6 in the production of readings along the glen 7.

Chambers 1 and 2 together with measuring tubes 6 are placed in a common casing, the wall 9 of which you: also filled out of a substance that completely reflects radiation, and the air from the internal cavity of the casing is removed. A special protection is put on the tubes 6 when making observations.
