Purchase Brazetek HVAC heat exchangers here HVAC (heating,
ventilation, air conditioning) is the technology which helps
maintain a consistent indoor temperature. Using HVAC the
conditions in a closed area can be maintained using fresh air
from outside. It can be kept warm or cool as required. The
heating effect is produced by using a boiler and heat is
transferred using water and heat transfer takes place by
convection through circulation of water. Ventilation includes
the exchange of air with the outside and also circulation of air
within the building and maintain an acceptable level of air
quality in a closed atmosphere. Air conditioning is provided
through the removal of heat through a process called the
refrigeration cycle. As the liquid refrigerant cycles and
evaporates it absorbs energy from air, repeats the cycle. In
this process heat is absorbed from indoors which results in
cooling of the building. There has been a consistent effort to
make HVAC more efficient.
