Abstract:
The invention relates to a method and a system for transferring heat from a vaporous medium (7) which condenses at least in part in a condensation heat exchanger (1) at a working pressure exceeding 1 bar. Condensate formed during said process is withdrawn from the condensation heat exchanger (1) and is expanded to reach a lower pressure. According to the invention, the vapor phase (10) produced during the expansion is compressed to the working pressure of the vaporous medium and is then fed directly into the condensation heat exchanger (1) or is supplied to the vaporous medium before the vaporous medium enters the condensation heat exchanger (1). The vaporous medium is especially steam.
Abstract:
Die Erfindung betrifft ein Verfahren und eine Anlage zur Übertragung von Wärme aus einem dampfförmigen Medium (7), welches bei einem Arbeitsdruck von mehr als 1 bar in einem Kondensationswärmetauscher (1) zumindest teilweise kondensiert. Anfallendes Kondensat wird aus dem Kondensationswärmetauscher (1) abgezogen und auf einen niedrigeren Druck entspannt. Die bei der Entspannung entstehende Dampfphase (10) wird erfindungsgemäß auf den Arbeitsdruck des dampfförmigen Mediums verdichtet und anschließend direkt in den Kondensationswärmetauscher (1) eingespeist oder dem dampfförmigen Medium vor dessen Eintritt in den Kondensationswärmetauscher (1) zugeführt. Als dampfförmiges Medium wird insbesondere Wasserdampf verwendet.

Abstract:
In a cooling system for transferring a heat flow from a heat source (Q) to a heat sink (S) formed by an air current (L) having a closed coolant circuit (1) and an adiabatic or evaporation stage (2), the closed coolant circuit comprises a first heat exchanger (3) having a thermally conductive connection to the heat source and a second heat exchanger (5) having a thermally conductive connection to the heat sink. The adiabatic or evaporation stage includes at least one air humidifier (8) adding evaporation water to the air current forming the heat sink, wherein said air humidifier can be supplied with evaporation water via an evaporation water line (11). A coolant cooler (13) is furthermore arranged in a coolant line (7c) leaving the second heat exchanger of the coolant circuit. Said cooler is designed as a plate heat exchanger, the second line of which is switched into the evaporation water line (11).
