Method for heat energy transmission
The invention relates to a method for heat energy transmission between a gaseous, warmer medium on one hand and a liquid, colder medium on the other hand. In order to provide an improved method for heat energy transmission, the invention suggests a method in which the liquid and the gaseous media are passed by each other using a plate heat exchanger, wherein the gaseous medium is cooled down and the water contained therein is condensed out, while the heat energy released due to condensation is transferred to the liquid medium.
1. Method for heat energy transmission between a gaseous, warmer medium on one hand and a liquid, colder medium on another hand, the method comprising:
passing the liquid and the gaseous media by each other using a plate heat exchanger, wherein the gaseous medium is cooled down and water contained therein is condensed out, and
transferring the heat energy released due to condensation to the liquid medium, wherein a quantity ratio of the liquid to the gaseous medium is selected as a function of the temperature difference between the liquid and gaseous media at the beginning of the transferring of the heat energy.
2. Method pursuant to claim 1 , wherein a flow of the gaseous medium is divided into a main flow and a secondary flow before reaching the plate heat exchanger.
3. Method pursuant to claim 2 , wherein the secondary flow of the gaseous medium is guided around the plate heat exchanger.
4. Method pursuant to claim 2 , wherein the main flow of the gaseous medium, after passing the plate heat exchanger, is mixed with the secondary gas flow of the gaseous medium guided past the plate heat exchanger.
5. Method pursuant to claim 2 , wherein a quantity ratio of the main gas flow to the secondary gas flow is selected such that a drop below the acid dew point is prevented.
6. Method pursuant to claim 1 , wherein a hybrid heat exchanger is the plate heat exchanger.
