Definitions

  • the invention relates to a device according to the preamble of claim 1 and a method using the device.
  • the object of the invention is to coordinate the design, dimensioning and mode of operation of the components of the heat exchanger through which the liquid flows so that fully automatic venting of the components carried by the liquid takes place and thus an operationally reliable function is ensured. Furthermore, the manufacturing, assembly, commissioning and operating expenses are to be reduced.
  • the pump may have to be designed accordingly or the pump motor is briefly driven to higher output with a frequency converter. Or sections of the circulatory system are short-circuited with a bypass circuit so that the pump output only acts on the heat exchanger to be vented.
  • the central control technology / building control technology advantageously contains a control program part which intermittently switches on this fluid flow.
  • the device for the reliable operation of heat exchangers has a plurality of parallel liquid-flow components for heat transfer between liquid and liquid / gaseous media. For fully automatic ventilation of the components through which liquid flows
  • the flow differential pressure is maintained if the process-related liquid mass flow is chosen to be a factor preferably ⁇ 1.0 higher than the sum of the static pressures from the gas / liquid columns of each flow path resulting from the height differences.
  • the flow channels designed for heat transfer are simultaneously dimensioned and designed in such a way that the above-mentioned flow differential pressure required for each component through which liquid flows is built up.
  • the necessary differential flow pressure can also be achieved by temporarily increasing the liquid mass flows, so that any accumulated gas cushion is expelled.
  • plant components such as Pumps, bypass circuits and controls are dimensioned and designed accordingly.
  • the factor " j ⁇ .1.0 is determined by fluidic measurements for the components through which the liquid flows, including any additional influencing variables such as surface toughness, viscosity, etc.

Abstract

L'invention concerne un dispositif pour assurer le fonctionnement fiable d'échangeurs thermiques comportant plusieurs éléments parallèles à travers lesquels circule un liquide destiné à transférer de la chaleur entre des milieux liquides et des milieux liquides/gazeux. Dans le but d'assurer la mise à l'air libre entièrement automatique d'éléments présentant des saillies verticales et parcourus par un liquide, notamment dans des circuits hydrauliques commandés à contre-courant, les éléments parcourus par un liquide sont conçus de telle manière que la pression différentielle d'écoulement est supérieure d'un facteur de préférence ≥ 1,0 à la somme des pressions statiques provenant des colonnes de gaz/liquide, engendrées par les saillies verticales, dans chaque voie d'écoulement, dans le respect du flux massif liquide inhérent au processus.
