How does the frost-free function affect the energy consumption of a refrigerator? The frost-free function increases energy consumption due to the periodic activation of the heating coils to defrost the freezer, but it offers the convenience of not having to manually defrost the freezer. Is manual...
Physicist: “Making cold” is impossible, so a “refrigerator” is really just a heat pump. Scientists don’t talk about much beyond of a handful of thought experiments. Quantum physicists: double slit, relativists: trains, thermodynamicists: mirrored boxes and pistons, etc.. Refrigerators can ...
Air conditioners don't have the exterior housing a refrigerator relies on to insulate its cold box. Instead, the walls in your home keep cold air in and hot air out. Let's move on to the next page where we'll discover what happens to all that hot air when you use your air ...
Almost any gas can be used as the working fluid inside of the Stirling engine, but there are only a few gasses that make sense. The lighter the gas, the better it does its job of transferring heat inside the engine. Hydrogen would be the optimum gas. Helium, however, would also be a...
I get asked a lot of questions about electricity in RVs, and while my background is not as an electrician, I have gained knowledge of the RV systems through trial and error (luckily not too much error). Electricity and RVs are a bit complicated. The main
How Does AC Work in a Car? A car's air conditioning works by manipulating pressure and temperature to move refrigerant between a liquid and gaseous state. The refrigerant enters the evaporator as a liquid, and the heat of the car transforms it into a gas. In its gaseous state, refrigerant...
How Does an Absorption Fridge Work? This absorption refrigerator diagram shows the cooling cycle of an absorption fridge. (Photo credit:Wikipedia) An absorption fridge uses either a propane burner flame or an electric heating element to work. ...
A portable generator is a convenient way to safely produce your own power when the grid goes down, either due to natural or man-made causes. But how does a generator work? Whether you’re new to using a generator, or well-experienced, there are a few things you need to...
What Kind of Gas Does a Generator Use? The type of gas a generator uses impacts its performance, cost, and environmental footprint. Here are the common fuel types: Propane:Consume fuel quickly but create less pollution and fumes than gas or diesel. ...
How do air-conditioned seats work? Do they still use a central car air conditioner or is the air conditioner located in the seat itself? How does the air get out of the seat so that it can cool the person sitting in it? Can you buy air-conditioned seats for cars that don't have ...
