At the end of last September, the pilots of the HyCool project (Industrial Cooling through Hybrid system based on solar heat) began their way to start-up. In this initial phase of project execution, the two demonstration sites have started the civil works with which the necessary infrastructures are built to house the equipment and all parts of the system. These works are developed on the following fronts:
Givaudan: installation of the solar field on a plot adjacent to the plant; construction of a prefabricated technical room next to the solar field that will provide water vapor to the production plant from solar energy and with the technology supplied by Ecotherm; construction of the technical room that will supply cold to the plant, using adsorption pumps built by Fahrenheit.
2. Bo de Debó: installation of the solar field on one of the warehouses of the production plant; construction of the technical room that will house the hot and cold water production system using using Fahrenheit hybrid heat heat pumps and Ecotherm solar technology
The construction works are expected to be completed by the end of November 2020, giving way to the installation and commissioning stages of the HyCool systems, whose commissioning is expected in mid-June 2021.
Powering of industrial processes, if based on renewable technologies, may offer greater potential for CO2 emission reductions. Solar thermal energy is a promising sector which has been widely studied during the last two decades, becoming a candidate of the highest potential among renewable energy technologies, especially for industrial heating and cooling processes, because some technologies, such as heat pumps and mechanical vapour recompression, are particularly effective in hybrid systems.
The use of direct solar heat in industry is often hampered by barriers like lack of nearby available surface and seasonal imbalances. However, recent solar steam developments applied in the cooling demand services is growing worldwide with a wider variety of use, mainly within the industry. Some technologies, such as heat pumps are particularly effective. The two demonstration sites selected to tests Hycool system (Bo De Debó and Givaudan) are industries where custom-designed packages will be built, installed and tested.
Bo De Debó is a specialised industry in preparing precooked fresh dishes based on meat, fish and vegetable products, for being frozen, vacuum-packed or canned, and then sealed. In this site, Hycool will pre-cool the water in a buffer tank where it should be cooled down with other chiller in order to get 3-5ºC needed for the production of “gazpacho” (a kind of vegetables juice) and food washing processes. The residual heat from the system will be used to produce hot water for cleaning operations.
Givaudan is the global leader in the creation of flavours and fragrances. In close collaboration with food, beverage, consumer product and fragrance partners, Givaudan develops tastes and scents that delight consumers the world over. The Hycool system will provide the cold water needed to refrigerate the glycol stored in a buffer tank before it’s pumped to the vacuum pump water rings. The residual heat from the system will be used to produce steam to be injected in the factory net.
In summary, the solar thermal energy provided by the Hycool System will allow our pilot sites:
To reduce their productions costs by using a free source of energy
To increase their system efficiency by using the residual thermal energy for producing heat water or steam
To reduce their global CO2 emissions by reducing the use of fossil fuels for producing that heat
