Optimal Design of Air Coolers and Air Heaters by Means of Electronic Data Processing.

The electronic data processing for technological estimating has been coming into use by the refrigerating and air conditioning industry during the last few years. With the exception of a few large undertakings and universities the application of such plants was in the main found in the commercial sphere. New computers however with better external data stores, higher internal calculating speed, improved soft ware and a more favorable cost-performance ratio, have incited also smaller and medium-sized enterprises to install electronic computers. Compilation of calculation programs is explained both for air heaters and air coolers.
