The training provides design engineers, qualified safety personnel, and industrial hygienists a comprehensive understanding of IV systems. Students must bring a calculator with exponential functions. Imagine the cost saving. You may have this on your next project. During the winter, the outdoor air supplied to ventilation systems must be heated.
Solar walls provide an efficient, reliable, zero maintenance air preheater.
These walls are most effective in sunny winter areas. In the summer the solar heated space is bypassed. Payback has been documented to be as little as three years. Dark perforated steel sheathing surrounding an air space against a wall, sealed at the edges, provides a heating space for air drawn through the perforations and into the building. A 40-degree F temperature rise is feasible.
