Fundamentals of Energy System Optimization in Industrial Buildings

9 FUNDAMENTALS OF ENERGY SYSTEM OPTIMIZATION IN INDUSTRIAL BUILDINGS 

This section briefly introduces the energy aspects that have to be taken into account in system design. The building-related features are covered in Chapter 11, mainly from the energy-calculation point of view, with less attention paid 

One simple example describes the problem the efficiency of a heat recov ery device can be increased from approximately. 50% up to approximately 75% by using a double unit. This will double the pressure drop from, say, 100 Pa to 200 Pa, resulting in the fan energy s increasing respectively. 

Measures undertaken to improve the indoor air quality (lAQ) have the same effect by upgrading the filter class, increasing the air change rate, etc. These small improvements have grown both in number and in size, little by little.
