Heating & cooling

When using the Scheuch LIGNO recovery+ technology, an additional heat exchanger for painting systems is set up outdoors. Compressor technology can therefore be used to cool the air down to minus 8 degrees. The feed temperatures reach 30 to 40 degrees, heat that can later be used for the entire painting system ventilation system.

However, energy can also be saved when cooling in addition to when heating. Cooling guarantees constant production conditions. Furthermore, pleasant working conditions do not just improve employee comfort but also occupational safety. A classic painting system has a cooling capacity of around 180 kWh. Conventional cooling systems therefore require around 50 kWh of energy. In the Scheuch LIGNO adiabatic cooling system, only 0.5 kWh of energy are required, i.e. over 99 percent less. The adiabatic cooling system works by wetting with water. High pressure and micro-drip nozzles are used to make the finest mist out of the water, which is fed into the supply air or exhaust air duct system. This fine mist, also known as an aerosol, takes the warm energy out of the air and gives cool energy in return.

A difference is made between direct and indirect adiabatic cooling. In the direct design, the supply air is humidified directly. In indirect cooling, the exhaust air is humidified and the cooling output is transported to the supply air current via a heat recovery system. In addition to high energy efficiency, another great benefit of the adiabatic cooling system is that no further noise emissions occur outdoors.
