Mechanical Ventilation System with heat recovers
The second individual system in our Multi-Objective Optimization (MOO) journey is the heat exchanger model Xpelair. In a mechanical ventilation system with heat recovery (MVHR), the heat exchanger is the heart of the system and ensures, through its filters, that the entering polluted air is cleaned before being pushed through the ducts and into the rooms. The primary purpose of heat exchangers, especially Xpelair, is to save as much energy and to thereby decrease the greenhouse emissions.

The major components, that have been studied during a previous Life Cycle Assessment, are the cover, made of galvanized steel sheet, the insulation, made of rubber seals and the filter material, in our case G4 filters made out of polyester. The quantity of each material was determined by extracting the system’s dimensions as seen in figure 1. As a result, the Xpelair was determined to be the best choice out of two different heat exchanger models regarding environmental impacts as well as monetary issues.
