As output of the TURBOSOL, heat transfer fluid (oil) is re-injected in the heat exchanger to start over its valuation run. However, the vapour stands between 80 and 90 °C; then it has to be cool down before collecting thermal energy again.
Different cold source typologies are possible according to the implantation site configuration and thermal discharge needs of the heat source.
Cold source to be warm up within cogeneration principle
Using thermal discharge of the outlet vapour of the TURBOSOL to warm up a heat network (/cool down a cold network) or domestic hot water allows a second waste heat valorisation. Thus, the system global efficiency is close to 90% ! Moreover, regarding actual environmental issues, circular economy may make a difference, even in the energy field.
Natural cold source to reduce costs
Being free of charge, if a natural cold source is available and useable next to the implementation site of the TURBOSOL, it is very interesting. HEVATECH engages to respect carefully regulatory threshold of thermal discharge temperatures, in order to have a minimum impact on nearby biodiversity.
Artificial cold source within containerisation approach
Despite the small portion of electricity cut from the TURBOSOL production to run the air cooler, this solution is viable, especially in hot environments. Moreover, the system is then completely independent, so it can be placed in a container to be easily moved at any time.
