Fans

So, bros, I've been facing some problems with one of my lockers (capacity: ~ 10-12 robusto boxes).

It's reaching 70% in hot days (25º C). I tried some low% Bovedas but it didn't work.

I bought a little fan (http://www.o2-cool.com/5-inch-portable-fan-fd05004?page_id=841) and put inside of it to cool it down.

Well... nothing happened.

Any input? Have you tried fans before?

I've got a couple of Oust fans in my Aristocrat M Plus and think they help to distribute the humidity levels more evenly.

The multiple hygrometers seem to bear that out though it may be just wishful thinking.

Pretty sure a certain Orthopristis chrysoptera could provide additional input....

So you tried to place a fan inside the closed locker to reduce the temperature? is that correct? That will not work. The fan will only move the air, it won't cool. If anything, there is a possibility it will actually HEAT the inside of the cooler because the fan has to run on some sort of motor and that motor has to create heat somewhere.

If your aim is to cool the inside of your cooler, then you have to move it to somewhere in your house that's cooler. Otherwise the only way to do what you are trying to do (reduce the temperature) is by using an active cooling system... ie a fridge.

Why is only one of your lockers increasing in temperature though? What are the others doing? And what is the ambient conditions where the lockers are stored?

The real question here is this.

Is this situation really affecting your smoking experience?

I ask this on two fronts and from a position of theory and not really reality. I don't know the reality of it...

How wet is it in your room? I ask this because if the ambient is high then you need a solution to lower humidity and this 'is' the problem. If the ambient is not high, then open the locker and let some of the water out...!

High rH is not really your enemy... Okay, you can stop flinging internet feces on your screen when you hear me out. High rH is only really a problem when combined with low temperature. As water energy rises, the cigar has lesser ability to hold on to it. Meaning that the proper amount of water can be maintained at a higher rH level as long as the temperature of the cigar also rises (cigar temp= water in the cigar temp).

So, how are the cigars smoking? Stop focusing on the damn dials, and fly the plane!!! (What an old flying instructor used to shout at me...) That is your measure.

On the long term if the ambient rH is high you will likely develop a problem so it is still wise to watch the hygrometer. On the other hand, I am emphasizing not to get mesmerized by it and crash the airplane!

Get me some answers and I will try to responding later to your findings.

Cheers! -Piggy

Yes, I thought fan would decrease temp few degrees and it would be enough.

It didnt heat. I tested the fan and even after hours it's still cool.

Others are ok. I have all my cigars in a big room. Dont want to move. I think there are too many boxes inside the locker. Maybe I shouldnt work with full capacity.

I dont like my cigars at 70%. It always burns out during the smoke. And to the long term storage I prefer lower Rh% as well.

My room is 65-70% and temp not stable.

When is cold the Rh declines. When is hot the Rh raises. That's why I thought a fan would work.

Fans actually produce heat, they don't remove it. You have electrical energy (battery/power source) converting to mechanical energy (motor). This conversion is not perfect due to the laws of thermodynamics, and energy is lost to the environment as heat. We feel a cooling effect from a fan because it increases the amount of sweat which evaporates from our skin, even though the temperature in a room is getting warmer directly from the fan.

Your fan was probably small enough to give negligible heating during the time you had it on.

"We feel a cooling effect from a fan because it increases the amount of sweat which evaporates from our skin".

So let's forget about the heating of the engine fan. If I turn it on inside a room the room will not have its temp decreased?

If you turn on a fan inside a closed room, the temperature will increase. The reason we don't notice this is because generally the fan will be directed at our bodies which produces a cooling effect. Our body temperature will decrease, however the ambient room temperature will increase. A fan itself is not an air conditioner and there is no way that it can remove heat. However, we are putting energy into that fan, and energy=heat.

But how a fan in a car motor cools it? And computers?

But how a fan in a car motor cools it? And computers?

They work in two different ways.

With a computer it's a bit simpler. It's basically an air exchange. You have a fan which is an exhaust fan, which removes hot air from the computer. Then there is an intake fan, which sucks in cooler air from around the computer. Hot air goes out, cooler air comes in. Since the cooler air is a lower temperature that the components in the computer, heat transfer will occur between the hot components and the cool air. In our fan in a room scenario, all air is the same temperature. We are not removing hot air or bringing in any cooler air, just moving around the air that is inside the room

A car motor uses cooling water to cool then engine, and air from the fan to cool the hot cooling water. Cold cooling water moves around the engine, causing that cooling water to become hotter and the engine to become cooler. This hot water gets pumped out of the engine blocks and into the radiator. Fans blow air onto the radiator tubes. This air is cooler than the hot water inside the radiator. This causes the the cooling water to decrease in temperature, and once it leaves the radiator it is cool enough to be sent back through the engine block to cool the engine.

What we have in both these cases are temperature differences. In the computer, the cooler air coming in is cooler than the components. In the car, the air blowing from the radiator fans is cooler than the radiator coolant. A temperature difference is required for heat transfer to occur.

In a sealed room all the air and all the furniture are basically the same temperature. We are taking air at, let's say, 25degrees, and moving that 25 degree air around the room. All that is happening is we are increasing the velocity of the air. But since everything in the room is still 25degrees, there is no temperature difference and hence no heat transfer.

Ok, got it.

Thanks for the full answer.

To address your initial problem, I have had one thought which I have not yet experimented with and I don't know if it's applicable to you or not because I'm not sure what a locker is. I have a coolidor and experience pretty high temperatures in summer. My thought was that during summer, I could get a large tupperware style container and put all the cigar boxes inside there, which would then go inside the coolidor. In the space between the tupperware box and the cooler you would put ice packs. Condensation shouldn't be a problem since the cigar boxes are in a sealed tupperware box so any water which collects inside the cooler shouldn't matter.

As I said, I have not tested this. Has anybody done this before or can anybody comment on whether this would be a good or bad idea?

Then just keep on putting ice packs in the collerdor every day? Your tupperware temp will drop down to atleast 5C if you have a half decent insulated cooler. If you were going to go through all that effort, I say just get a fridge.

Replacing it everyday would be overkill if it's already down to the desired temperature and it has decent insulation. Once a week might do the trick. I'm in Melbourne so it's only a couple months a year when it's required, plus is much cheaper than a fridge.

Aushy, my locker is like that (borrowed from another thread):

I have the same footlocker and a similar problem where my rH was too high. My experience with this was that my room was way to hot in the summer sometimes going up to 26-27degrees celcius! I'd come home to check on my babies and the hygrometer would read 72+ at times... My remedy was to put it in the coldest room of the house which was the basement. Now the problem is solved :) My rH fluctuates approx 2% + - around 64rH and temperatures are always between 16celcius to 20 celcius.

Thanks, buddy, I think this will be the way: changing room.

I just have to say that the discourse in this topic was inspirational to read. Not a lot of communities I've seen online have such polite and helpful members.

Now my two cents. I keep my house at 70f/21.11c in the summer and 65f/18.33c in the winter. I move the cooler to the basement during the summer to keep the temperature closer to a steady 65f, and occasionally I'll throw ice cubes, made with distilled water, in a little dish into the cooler to bring down the temperature.
