52 F water is plenty cool for use in a cooling coil. Most commercial HVAC system chillers produce water at 52 to 55F. You can expect to bet air off this coil at maybe 57F, if it is about as efficient as a commercial cooling coil. This is well below dew point temperature on most summer days, so the coil should stay dripping wet as it dehumidiffies your house. Here's a rough way to calculate your heat capacity. Your engine develops XX horsepower. It is not much better than 35% efficient, and the rest of theat energy is basically heat. Some of the heat is radiated by the engine directly, let's say another third to be conservative. So you can expect your radiator can dissipate an amount of heat equivalent to at least the horsepower of your engine, and probably closer to twice as much. Have any idea of your engine horsepower? --lawrence ----- Original Message ----- From: "Tal Bejerano - AMC" To: Sent: Wednesday, June 19, 2002 4:11 AM Subject: Re: [OT]: Car Radiator for Air Conditioning > Hi Martin > > I think the all system will not work, even if you have water source below > 10c. > > try to rich the humidity if you are living in a very dry area. > > Regards > > Tal Bejerano > AMC - ISRAEL > > > -----Original Message----- > From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On > Behalf Of Martin Buehler > Sent: Wednesday, June 19, 2002 8:42 AM > To: PICLIST@MITVMA.MIT.EDU > Subject: [OT]: Car Radiator for Air Conditioning > > > i would like to use a radiator from a small car for air conditioning my > house: > > i have a source of cold water (about 10C, i think that's about 52F). so i > would like to circulate this water through the car radiator. > there's a heater, which is originally placed in the air distribution > system, i have in my house for heating in wintertime. i want to replace it > with the car radiator to cool down the air in summer. > i have no idea if this works, as i have no data of such a car radiator. > has anyone done something similar, or does anyone know about the active > surface of such a car radiator and the thickness of the lamella (between > air and water)? > or does anyone have any data of such a radiator, that help me calculate > how much power i can 'destroy', depending on the airstream and temperature > difference? > thank's a lot!! > tino > > ps: > wonder why i ask this in a pic forum? for shure, i pic will control the > whole thing! > > -- > http://www.piclist.com#nomail Going offline?
