The heating system has recently been ___ to make it more efficient. A. modified B.
aThe most important and cost effective element of an efficient heating, ventilating, and air conditioning (HVAC) system is a well insulated building. A more efficient building requires less heat generating or dissipating power, but may require more ventilation capacity to expel polluted indoor air. ...

been very good at the heat-generating part compared to a stand-alone solar thermal collector. That"s because they operate at low temperatures to cool crystalline silicon solar cells,___ (52) lets the silicon generate more electricity but isn"t a very efficient way to gather heat.That"s a ...
Researchers from Tsinghua University and Brown University have discovered a simple way to give a major boost to turbulent heat exchange, a method of heat transport widely used in heating, ventilation and air conditioning (HVAC) systems.
Power-generating solar panels can take up a lot of space, leaving less room for solar heating systems. An ingenious discovery at Michigan Tech could lead to efficient, economical solar energy systems that can power your lights and heat your water. ...
