Finned Tube----Air cooling evaporators
Air cooling evaporators for coldrooms, blast freezers, air-conditioning, etc., can have finned pipe coils. all told however terribly tiny coolers, there will be fans to blow the air over the coil.
Construction materials are a similar as for cool condensers. metallic element fins on copper tube are the foremost common for the halocarbons, with stainless-steel or metallic element tube for ammonia. Frost or condensed water can type on the fin surface and should be drained away. to allow this, fins are vertical and also the air flow horizontal, with a drain receptacle provided beneath.
The size of the tube are specified the rate of the boiling fluid among it'll cause turbulence to push heat transfer. Tube diameters can vary from nine millimeter to thirty two millimeter, consistent with the scale of coil.
Fin spacing are a compromise between compactness (and cost) and also the tendency for the interfin areas to dam with condensed wetness or frost. Spacings can vary from a pair of millimeter on a compact air-conditioner to twelve millimeter on a low-temperature coldroom coil.
