HVAC is an acronym that stands for Heating, Ventilation, and Air Conditioning. HVAC provides correct air flow and meet room-by-room calculated heating and cooling loads.
During the last years, the HVAC systems have been becoming more energy efficient. This was mainly driven by rising energy costs and secondly by environmental issues. We´ve already presented several technologies for making heating, ventilation and air conditioning systems more energy efficient, e.g. forced air systems, ventilation energy recovery and heat pumps.
