I know of air to air and water to air heat exchangers. Are there any other fluids that are commonly used to cool and heat outside air? I'm trying to find a safe fluid that can be used in air coils which will not freeze in the winter and has a high enough thermal capacity to absorb a lot of heat. Maybe you know of a refrigerant that would work ???
High temperature heat transfer fluids can be categorized by chemical structure into three primary groups: Synthetics Hot Oils Others including silicones The synthetics, also referred to as aromatics, consist of benzene-based structures and include the diphenyl oxide/biphenyl fluids, the diphenylethanes, dibenzyltoluenes, and terphenyls. Depending on the specific product, the overall bulk fluid temperature operating range of the synthetics is from -70°F to 750°F.
All condensers are warmth exchangers yet not all warmth exchangers are condensers. warmth exchangers could be used to warmth or cool a liquid or gasoline applying a 2d liquid or gasoline. A condenser is used to chill and alter the state of a vapor right into a liquid, frequently steam into water. As such the condenser could have greater room interior of it for a great quantity of vapor to get carry of optimal warmth flow floor section. There is additionally baffles to direct the steam and shelter the tubes from erosion and to direct noncondensable gases to and orifice the place they could be got rid of, in line with risk via an air ejector.
The specific heat of water is hard to beat. Unless temperatures are REAL extreme, just add glycol.
There are all kinds of them. Like above you can add ethylene glycol to water to make water so that it will not freeze(as in a car). And then there are the refrigerants that are used in air conditioners that go through a gas liquid cycle. Ammonia also works but is a bit dangerous to handle. And you can also boil off water to make steam and condense it in radiators.
