they only work if you live som ware ware it gets very cold. He said its like freezing ware he lives. There ist evean a need for cooling. what a lucky ass. This is no ware neer as powerfull as an ac. also the unt most people here woud use is AN EVR not HVR the enrgey ventilation recovery works in reverse and cools the room and takes out humidity.

Despie: you must tell us some numbers:
1) your outside air temp while this thing is dribbling water and icing over
2) your outside RH, relative humidity at same time/temp as above
3) your growroom temp and humidity
Let me make some guesses:
1) outside air in Spain, during winter = cold
2) it is Spain, in the winter, RH is low
3) your growroom is 72 F and a little more humid than your outside air
So, what does this accomplish? (when it is cold and dry)
1) you heat your fresh air for free with waste heat from the lights
2) you recover some of the plants' transpiration water as a nice source of distilled water
3) you dehumidify your exhaust air
4) you mask the effect of the "fire breathing dragon"
But wait, there really is a use for these things.
1) air from your house (bedroom would be best: you are the CO2 generator) goes directly into the grow room Since your bedroom is the most important room to heat in the winter, your plants benefit from your heat or 55-60 F, if you like it cold. No danger of freezing your plants as you will freeze with them.
2) now, for the heat exchange: odor-filtered grow room exhaust goes in one side and then right out through the wall minus a lot of heat. (Use the most powerful fan between the carbon filter and the heat exchange.)
3) Finally, we have the second "channel" of the heat exchange. Use this to draw in fresh air from outside and heat it with grow room waste heat. Depending on outside temps, you may not want this jetting directly into your bedroom, but perhaps somewhere else in your house if it is sealed as a single unit.
4) You still get distilled water from your growroom air moisture.
What this does is heat your house with growroom waste heat and avoid odor problems inside your house.
If you want to benefit from the dehumidifier effect of the heat exchanger then use some of that sheet metal you have to build a negative-pressure-chamber for the odor filter downstream of the heat exchanger. In this case, put the most powerful fan as the last thing before the outside exhaust vent.
Your grow room will be at lower pressure than house which will be at lower pressure than outside. Carbon filters work much better when the air is dry so no odor, no wasted heat energy (unless 3K won't heat your bedroom).
Where I live it is 85 F at night, in the summer with 98% relative humidity. No swamp coolers here.
The only way that thing will cool below outside temps is if you have super dry air (Spain, check) and put a few water mist jets in the intake air stream.

im re working the thread dudes....blynx sort of hit it on the head. The system is working in reverse because of the way its installed. this works and it has its place.
Bonsai: Some of what u just said is in the new section of the thread.
It may take a few days as I am writing it so theres NO confusion!!!
take care, have to goto work now!!!!!
theres always contraversy when something is found out that seems to good to be true. Calling it bullshit and this or that is contradicting what these forums are about and sort of why i left the whole internet forum scene. I'm not here to bullshit anyone, I have nothing to gain.
hold off on questions until I repost everything!

despie-please dont take the questions/critism personally. when somthing new/revolutionary comes along it is always met with skeptisism. personally i am very curious about this thing & any new info is appreciated!

btw please tell us about the drain waste from this thread it is saying that the drain water is supposely HOT. Or its just regular water and the dehumified air that is condensated gets colder kinda like when it rains the temp drop.

dude... you have absolutely NO idea what thermodynamics is. you quickly looked up a wiki link and tried to learn?!!?!?! READ THE FIRST SENTENCE IN YOUR LINK. its a LAW of physics. BECAUSE OF THERMODYNAMICS, your system is nothing more then complicated vented room. your keeping things cool because youre moving so much air, not anything else. not 'condensation', not 'evaporative cooling' nothing. trust me. you cant run a heat exchanger in reverse and get an air conditioner. YOU DO HAVE ONLY TWO PORTS- one in from outside, and one out from inside. youre pushing MASSIVE amounts of fresh air exchange with that system, but to only make it worse you are COOLING DOWN your exhaust with your NICE COLD INTAKE. why? why would that benifit? IT DOESNT. NOW YOU HAVE WARM INTAKE AND YOUR ROOM IS EVEN WARMER THEN IT WOULD BE WITHOUT A HEAT EXCHANGER. peace for now

Oh wait, I was thinking. Despie has an air-cycle air conditioner. Those are fine if you have a couple high power axial fans in series to compress one side and rarify the other. Yeah, 2 kilowatts of fan power and you just may have a few hundred BTUs of refrigeration. Add to that the possibility of a couple dozen more BTUs refrigeration if the condensation is happening in the right place...entropy energy of a humid room in a dry Spanish climate. Never mind me, I am not good with thermodynamics.

Doesn't this just warm the cool air coming in with the hot air going out?Despie said:
Didn't read the tread, but if your using co2 (or don't want smells to escape)and don't want it to escape, you should have the "fresh air from outside to room" connected to blow air strait out,and the "stale air from room" and "Stale air to outside" just circulating your cooled air in the room.

some straight up hard data will settle this argument in a heartbeat. take a temp measurement everywhere there is an exchange. so that would be
outside temp
temp from lights goin into hrv
temp leaving hrv
room temps.
that'll settle any arguments about this having any cooling effect or whether or not it is from just exchanging the air so much.

i think we scared him off...
i too live in florida. and it does get hot as hell. i mean, thats all you can say or think about outside on a mid summer day. and hunid as all get out. seriously. this is the hottest place i have ever been. i mean, you cant even go outside. its so hot, a water buffalo at the zoo, evaporated. i am bummed this isnt going to work, cuz summer grows here mean 24/7 a/c operation.
yeah sorry i didnt mean to go apeshit on the guy, but he wouldnt listen to me when i was calm, and he was also clearly misinformed on how air conditioners work. The reason he isnt posting back is because he probably asked one of his buddies at work and he finally realized he has a heat exchanger and nothing else.

yup time for this "bullshit" thread to be binned. Good work on calling it what it was. I read this crap a couple of times and started to feel retarded cuz I wasn't getting it. Now dude doesn't come back to explain this for two weeks. thats cuz it is "bullshit".
I think Blinddate should end this thread with a simple "BULLSHIT!"
peace
