Can an energy recovery unit prove more cost efficient than a make-up air unit?
• The cost efficiency ratio of an energy recovery unit depends on five criteria: 1. The number of service hours daily Yes. Large companies do so. In the food industry, food freshness, energy management and response speed (ice cream) have made food stores increasingly competitive. 2. The difference between exhausted air temperature and outdoor air temperature 3. The number of degrees-day in the region 4. The installation mechanical simplicity 5. Energy costs Where those five criteria are fully met, the return on investment on energy recovery systems is often feasible within two years.
