FAQ

why does the heat in my car work, but the air doesn't?

because they are both types of heat exchangers but completely different.your heater system works by passing hot coolant(water/antifreeze mixture) through a heater core(kinda looks like a mini radiator) under your dash that then heats the air in your air vents and then gets blown onto you. you air conditioning system has more to do with the way your refrigerator works. it compresses freon and then allows it to rapidly expand inside a special component under the dash, thereby cooling the air in your air vents which then gets blown into your face on that hot summer day. there are many problems that can arise to make your air conditioner not work. take it to a mechanic to have it diagnosed. they may have to add freon just to find out what is wrong with it and then take it back out to change the part to make it work again and then put freon back in it so it blows cool air again. EDIT: Diggle you are an idiot. its not hot air from around your engine

1. Warm air vents are often placed near the floor in each room of a house. Why? (What transfer of heat is used in these, and how do they warm up the rooms?)2. A student makes an electrical current out of a battery, a length of wire, and an iron bar. What should the student do to increase the strength of this current? 3. Can atoms be independent? (Not mixed with anything and not on anything?)

(1) Air registers are sometimes located at floor level on the theory that warm air will rise by convection. (It's actually done to save ducting, but the principle applies). The air in the room is pulled through a heat exchanger where it is heated by conduction and then returned. The warm air radiates some of it's heat, but this heat transfer mechanism is negligible in your example. (2) The student has very few options for increasing current other than minimizing the resistance of the circuit or increasing the batteries voltage. Wrapping the wire around the iron bar will generate magnetism in the bar, but will not increase current. (3) Noble gases meet the requirement of independent atoms, as do some others.

I have a Lennox Pulse 21 furnace installed around 1996 or so. A heating cooling company came out today to discuss installing A/C on the unit.After looking at the heat exchanger, he told me there was green corrosion and subject to Lennox's recall. He told me that Lennox will give me a brand new furnace for free, all I have to do is pay for installation.My concern is that he has a great incentive to replace my furnace because he will charge the labor for replacement, perhaps enough of an incentive to suggest replacing a furnace that doesn't need replacement (considering the fact that this is not why I called him out in the first place).Has anyone else replaced their Lennox Pulse 21 via this heat exchanger recall program? If so, do you have any suggestions?

I don't know about Lennox's furnace replacement program, but I am sure Lennox will tell you. Goodman has the same sort of thing but they only allow the contractor to charge a certain amount for the installation. I would check with Lennox first and foremost to get the details. I do know the Lennox Pulse units had quite a bit of trouble.

porsche 911 1972 2.4 i need a pair heat exchangers ,if anybody can help?

I guess I'd like to know, are you going to replace them yourself, thus you are looking for a parts source? Or are you looking for a place that will do it? I'd start by looking on Ebay.

Looking to put on one my cobalt ss/sc

thats a great deal, i got mine for 120. ur lucky, TAKE IT

72F tank air. 100psi72F outside air.72F engine block.Air into spark plug hole at top center. Air decompresses and chills. 15psi at 30F (just example)Stop the engine at bottom

Mythbusters did this, with a vaporizing wheel in a cold river. It turned itself but extremely slowly. But what he is saying, the atmosphere is a source of heat which can do work on cold decompressed air. Now if he uses a('air to air' atmospheric) heat exchanger for the cold air leaving the engine and used a compressor to also add HEAT needed to reach full recompression, it may be practical. Remember the energy source of compressed air is the latent heat of the atmosphere(which is of course, the sun). 100% of the energy to access that energy is wasted (electric, chemical, whatever) as heat. Every air compressor is 200% ENERGY efficient like a heat pump. What would happen if that 100% wasted heat energy was used to recompress air? Is it possible?

I have my thermostat set on HEAT.... and my FAN set on AUTOWhen thermostat reaches set temperture of 70degrees.....The furnance itself,SHUTS OFF.... but the Fan keeps blowing.I replaced the thermostat.. and the FAN,still wont turn turn OFFAny ideas what is wrong ??? Thanks !!!

It sounds like the fan/limit switch is bad. For more info including a troubleshooting guide, check out the furnace page at my source.

or air exchanger alone will solve our problem

yes you do. more in the winter months check with local home store to find out what your humidity level should be .
