Abstract: The present invention relates to an evaporator of a working fluid for an OTEC plant, comprising an elongated evaporator body extending along a main axis, a bundle of evaporators transporting hot water and extending along the main axis, and a sprinkling system extending above the bundle of evaporators and suitable for sprinkling the working fluid in the liquid state onto the bundle of evaporators in order to evaporate this working fluid. The evaporator body defines a bottom and an exhaust space for the gaseous working fluid between the bottom and the bundle of evaporators. The evaporator further comprises a damper system arranged in the exhaust space and configured to damp the drop of working fluid droplets in a non-evaporated liquid state after passing through the bundle of evaporators.

Abstract: The present invention relates to a working fluid evaporator for an OTEC plant, comprising an evaporator body extending along a longitudinal axis, a bundle of evaporators transporting hot water and comprising a plurality of evaporation elements, a sprinkling system extending above the bundle of evaporators and a casing covering the bundle of evaporators and the sprinkling system, an evacuation area being formed between end columns of the evaporator elements and the casing. The evaporator further comprises a redistribution system configured to collect the working fluid in a liquid state in the evacuation area and direct it to interior evaporator elements.

Abstract: The present invention relates to an evaporator of a working fluid for an OTEC plant, comprising an elongated evaporator body extending along a main axis, a bundle of evaporators transporting hot water, a sprinkling system arranged in an upper part of the evaporator body, a system for evacuating the fluid in gaseous state and a guide system for the fluid in gaseous state towards the evacuation system. The guide system comprises an elongated cover extending along the main axis, covering the bundle of evaporators and the sprinkling system, and two partitioning means which are arranged at each end of the evaporator body and form on each of these ends a sealed connection between the outer surface of the cover and the inner surface of the evaporator body.

Abstract: The present invention relates to an evaporator of a working fluid for an OTEC plant, comprising an evaporator body, a bundle of evaporators extending along the central axis, subject to a pressure drop along this axis and suitable for evaporating the working fluid according to an evaporation profile defined based on this pressure drop and a spraying system comprising a working fluid supply network and a plurality of spray nozzles arranged on the supply network and able to spray the working fluid. All of the spray nozzles have substantially the same spray rate and the arrangements of the spray nozzles in relation to the bundle of evaporators are chosen so as to ensure a predetermined spray profile along the central axis in accordance with the evaporation profile.

Abstract: An apparatus for heat exchange between a fluid circulating in a tube of heat conductive material and a flow of liquid in a thin layer circulating by gravity in a channel of heat conductive material, in thermal contact with the tube and disposed in the manner of a helix around the tube. The invention has application to evaporation, desorption, condensation, and absorption in chemical and physico-chemical reactors, and especially in air conditioning and refrigeration systems.
