When the dew point is close to the air temperature, the relative humidity is high, leading to a muggy and uncomfortable feeling. Why Is Some Air Dry and Other Air Moist? Very dry air typically has low absolute and relative humidity. This can occur in places with cold air, as cold air ...
When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts th...
This is called charging, and a charged off-peak cooling system takes very little energy to keep cold in stand-by mode until it's ready to be used to cool the air in an office building or home. As the building starts to warm up during the day, the air-conditioning kicks on, and ...
The expansion of the gas makes it even colder. This process takes place within a closed loop consisting of coiled tubes, so that it can be repeated over and over. Air is forced past the part of the loop containing the cold gas and becomes chilled. Constant input of energy is required ...
Outer space is an extremely cold environment and temperatures will vary drastically in different parts of the orbiter. You might think that heating the orbiter would be a problem. However, the electronic equipment generates more than enough heat for the ship. The problem is getting rid of the ...
For example, it is normal for either the fuel or the oxidizer to be a cold liquefied gas like liquid hydrogen or liquid oxygen. One of the big problems in a liquid-propellant rocket engine is cooling the combustion chamber and nozzle, so the cryogenic liquids are first circulated around the...
The entire action is basically a high pressure liquid, then released into a low pressure gas. If you take a can of hair spray and then release the product (hair stiffener), along with the propellant, the spray-can will get the cold. The exact same chemical reaction used by the air ...
Evaportor does not get cold enough What is Refrigerant? Refrigerant (often referred to by the DuPont trade name Freon) is a specially formulated cooling agent that can transform from a liquid to a gas and back again. It absorbs and releases heat, ultimately leaving cool air behind....
