Abstract: The device according to the invention is designed for growth acceleration and regeneration of lawn areas (2). It comprises a housing (3) which is open towards the bottom and can be placed on a lawn area (2) and delimits a space (6) above the lawn area (2), the housing (3) being formed so as to be transparent and/or comprising an illumination device (32) for illuminating the lawn area (2). The housing (3) is realized with a moving equipment (17) for automatically moving the housing (3) over the lawn area (2).

Abstract: A process to accelerate growth and regenerate lawns whereby the lawn (2) is at least partially surrounded on the top by a space (4) that is open downward and surrounded on all sides and whereby CO2 is fed into the space (4) and the space (4) covered by the lawn (2) is outfitted with a lighting system (14) and is subjected to light and a device for executing this process are disclosed.

Abstract: A cooling system is provided having a first heat exchanger for heating a cooling liquid, a second heat exchanger, which preferably comprises an evaporator, for cooling the cooling liquid, and a pump for guiding the cooling liquid through the first and second heat exchanger. The system includes a pellet reactor through which cooling liquid is fed, so as to remove impurities from the cooling liquid by grafting the impurities onto graft material in the pellet reactor. A method is also provided for using such a cooling system. An advantage of the system is especially that calcium salts can be grafted onto the graft material, as a result of which the concentration factor of the cooling system can be increased significantly.
