Abstract

Dwelling and working environments should be ventilated in order to
satisfy the need for healthy living space. In this article the mathematical
model for determining the economy in the case of investment into rotary
heat regenerator for ventilating systems is presented. The dynamic
economic method, which considers discount degree and inflation rate, was
used for economy calculations. This procedure enables relatively precise
calculations of operation of rotary heat regenerator. Evaluation of heat
savings was made on the basis of a curve of sum of days with average
daily temperatures for the previous five years.

Keywords

Average daily temperature; Dynamic economic method; Economy; Heat regeneration; Heat savings; Rotary heat regenerator
