11017/TUB: Method for Operating a Cooling System
Refrigeration systems have experienced have shown an enormous growth rate on the market in the past years, resulting in a growing demand for new and more efficient refrigeration systems. One way to increase the efficiency of the use of energy is to apply cogeneration systems, as they provide a resource-saving way for using cold temperatures and do not additionally raise the demand for power. Instead they utilize the waste heat of the power production directly for refrigeration purposes. Therefore, the aim of our invention is to provide improved technologies in conjunction with cooling systems to increase the efficiency of those systems.
The invention comprises a way to optimize the cooling or refrigerating capacity of an evaporator device, i.e. the transfer of thermal energy from the fluid to be cooled to the cooling agent, by supplying external thermal energy provided by an external heat source to the cooling agent in the reservoir of the evaporator device. Basically, this external thermal energy is used to externally excite the cooling agent in the reservoir to induce bubble formation or to amplify bubble formation already triggered by the cooling heat transfer. The latter can be the result of a so-called pool-boiling process, which is initiated by transferring the cooling heat from the fluid that has to be cooled to the cooling agent in the reservoir with the help of the cooling agent.
- Optimizing of vapor generation in evaporation processes for refrigeration in sorption cooling systems
- For cooling systems in which the process takes place in a vacuum
- Refrigeration systems and(?!) all application in which a fluid has to evaporate in portions on a heat exchanger surface
- Enhanced efficiency
- Applicable where common systems fail
- Intensified pool-boiling supports heat transfer
