Noisy air conditioners make life difficult. People want a quiet air conditioner but they have no idea what decibel (dB) they should look for. So, what is a good noise level for an air...

Chilled water pipes must be insulated to prevent condensation as well as conserve energy. Many junior engineers don't quite understand how the thickness of chilled water pipe insulation is...

Electric storage water heaters are often installed above the ceiling. As a result, many people don't get to see them and thus, they wonder how electric storage water heaters work? So, I'll explain...

Batteries are the most important element in electric vehicles. Tesla cars have long-range partially thanks to their superior battery cooling system. I'm curious to see how Tesla battery cooling...

Value engineering is not uncommon in HVAC. Engineers conduct value engineering exercises to save the initial cost of a new HVAC system. Although some people use value engineering as a cover to cut...
