Abstract: A method for transferring heat includes: heating an evaporator by a thermal energy source; providing a flow of a mixture of gaseous phases of a first and a second fluid over a steam line into a condenser; providing a flow of the condensed mixture over a liquid line into an accumulation tank; and providing a flow of the condensed mixture from the accumulation tank to the evaporator tank through non-return valves mounted on a return line. The method ensures transferring of a large quantity of thermal energy from a source to a receiver over considerable distances without application of porous capillary materials and additional processes for forced pumping of condensed fluid, regardless of the position of the source and the receiver in the gravity field.

Abstract: The invention relates to measuring engineering. In order to increase accuracy by increasing sensitivity, for the inventive dew point measurement method a light flux polarized in the plane of incidence thereof is used and directed towards the condensation surface of a dielectric cooled element at an angle at which the light flux is not reflected from the condensation surface of the cooled element in the absence of condensate.

Abstract: A Doppler flow velocity measuring unit wherein an optical unit including a laser and a photodetector is removably mounted on a pipeline is disclosed. The optical unit is attached to a pipe that is affixed to the pipeline at right angles to the flow in the pipeline. The pipe includes a shutoff valve that closes the pipe, permitting the optical unit to be removed from the pipeline.

Abstract: The proposed method of determining dew point involves directing the gas under investigation onto a cooled section of an optically transparent body through which a luminous flux is allowed to pass and recording fluctuations in the intensity of the luminous flux, the flow-rate of the gas thus directed onto the cooled section being reduced down to zero while its molecular diffusion is preserved. To limit the flow-rate of the gas impinging on the cooled section (1) and reduce contamination of the optically transparent element, the dew point gauge is provided with a sampling tube (10).
