The air we breathe is important for our life!
One can live 3 weeks without food, 3 days without water, 3 minutes without air!
People in industrialized countries spend indoor, on average about 90% of the year. Modern buildings and systems do not
allow natural ventilation. This is a major precondition for creation of mechanical ventilation.
The fresh air must be heated in winter and chilled in
summer, and this is related with significant energy
costs. There is a preliminary trend for growing of the
price of energy resources for the last 10 years:
Energy consumption leads to environmental pollution and exhausting of resources of the
planet. It is our duty to protect it for future generation.
Quickly return on investments using heat recovery systems:
Human health and productivity are closely connected with the air quality. Our children
need fresh air even more than us it could help to avoid illnesses and allergies.
The data shown are not universal. These parameters are valid
for the following conditions:
- Bulgaria, Sofia;
- Indoor temperature 22oC;
- Air flow 3000m3/h;
- Installation working time 10 of 24h.
- Installation life time 10 years;
- Energy price 0.1 Euro/kWh;
- 8% annual maintenance costs;
- Energy price growth 12% per year;
- The initial expenses are average;
Your lost money!
