Abstract:
Dispositif d'amélioration de production de chaleur par cogénération comprenant une source chaude produisant de la vapeur qui est détendue dans une turbine dont l'échappement est relié à un aérocondenseur (4) qui évacue de la chaleur, et comprenant au moins un second condenseur auxiliaire (5) sous forme d'un hydrocondenseur, le liquide de refroidissement de cet hydrocondenseur (5) étant dirigé vers une installation ou équipement (B) dans lequel sa chaleur est extraite et utilisée, puis le liquide est renvoyé à l'hydrocondenseur; l'hydrocondenseur (5) est intégré dans l'aérocondenseur (4).
Abstract:
A method for producing a heat exchange unit (22) for a recovery steam generator (20) comprising a tube bundle (24) each tube of which is equipped with segmented finning (26) jutting radially from said tubes (24), said segmented finning (26) being obtained by winding in a spiral and welding a metallic strip having a substantially trapezium-shaped cross section around said tubes (24), on said metallic strip a series of transversal cuts being made, which have a predetermined pitch and extend from a side edge of the strip, corresponding to the shorter base of the trapezium, for a predetermined depth, said strip being welded to said tubes (24) along the opposite side edge, corresponding to the longer base of the trapezium.
Abstract:
A condenser for a domestic split system air conditioner that has an evaporator. The condenser has a housing defining a duct through which to pass air, and a cross flow fan for inducing an air flow through the duct. A refrigerant inlet receives refrigerant from the evaporator, and a refrigerant outlet returns refrigerant to the evaporator. At least one tube through which to pass a refrigerant is connected to the refrigerant inlet and the refrigerant outlet. At least part of the tube is located in the duct to enable heat transfer between the refrigerant and the induced air flow. The duct has a width to height ratio that is no greater than 8:1.
Abstract:
Device for improving the production of heat by cogeneration comprising a hot source producing steam which is expanded in a turbine the exhaust of which is connected to an air condenser (4) which removes heat, and comprising at least one second auxiliary condenser (5) in the form of a water condenser, the cooling liquid of this water condenser (5) being directed to a plant or equipment (B) in which its heat is extracted and used, then the liquid is returned to the water condenser; the water condenser (5) is incorporated into the air condenser (4).
