You need to work your way around the entire building looking at every door, wall, window, roof, and other potential source of heat loss in turn. How much loft (attic) insulation do you have and could you do with some more? Is your home suitable for cavity-wall insulation and have you...
That's why wires get hot when electricity flows through them (something that's very useful in electric toasters and other appliances that use heating elements). It turns out that the higher the voltage electricity you use, and the lower the current, the less energy is wasted in this way....
“Induction Heating”. The eddy currents are concentrated at the surface of the material. The reason is that at high frequency, the imposed magnetic field changes its direction very fast. Therefore, the induced currents in one direction do not have enough time to penetrate into the depth of ...
Bigger air conditioners work a little differently: Central air conditioners share a control thermostat with a home's heating system, and the compressor and condenser, the hot side of the unit, isn't even in the house. It's in a separate all-weather housing outdoors. In very large buildings...
But how do glow sticks work? While it may seem like supernatural magic, the technology behind glow sticks is actually very simple. Let's look inside a light stick to find out how it gives off such a strong light with no bulb and no battery. Contents The Basics of Light The Chemical...
That's because without an electric field, the cell wouldn't work; the field forms when the N-type and P-type silicon come into contact. Suddenly, the free electrons on the N side see all the openings on the P side, and there's a mad rush to fill them. Do all the free electrons...
How does MEMS technology work to ensure a "no-drift" mass flow controller?MEMS Principle of OperationMEMS technology utilizes an advanced, ultra-stable, no-drift CMOS (Complementary Metal Oxide Semiconductor) sensor. The CMOS sensor houses both the electronic circuits and mechanical elements on a ...
Understanding the working principle of diesel heaters and the details of the work of diesel heaters will help you develop your diesel heater business, or make it easier for you to choose a suitable diesel heater.
Gas cooking appliances do require a dedicated gas line. One can easily be installed by a professional if you don’t already have one. HOW DOES AN ELECTRIC OVEN WORK? Many electric ranges, wall ovens and countertop ovens have two heating elements, a baking element at the bottom that ...
How Water Heaters Work Regardless of whether you are using traditional or modern water heaters, the water heating system works similarly. The difference is on the source of fuel, such as electric, solar or gas. When you want to understand how thewater heaterswork you, need to understand its...
