in cold seasons if we are placing the machine in outside indicates that we are decreasing their lifespan. the machines productive capacity will decrease by itself. so i think its not the good idea to place outside

If the temperature is low, the electrical circuits will last longer and work more efficiently. My miner works better in winter.

But what about unfavorable conditions for the miners if you expose them to the very low temperature? I agree that electrical circuits might work more efficiently but how do you manage to keep miners without excessive moisture etc ?

It burns their electromotor.and reduces the power

Should work with the mentioned conditions, BUT ...

... if you ever get a service interruption (power goes down) it will get dangerous with temperatures under +12°C for hardware.
And with under 0 and colder --- Your hardware will start to "sweat" in some seconds!
And power comes back after 1-2 minutes it will first slighlty work --- then the thin water-ice-condense will get back to liquid again and .... BUZZZZZZZZ  

Within a datacenter the airflow should not be under 16°C (and not over 23°C - some are even doing it with 26°C - cheap mass hoster!)
Humidity should be max 30% - most prefer lower!
Really hard - you have to drink water and water every minute you feel thursty

Without wet-problems it wont be such a problem. But you cannot lower the % of dryness without climate control.


What you should really try is:

1) Cold air from outside
2) Warm air from inside your box (circulation)
==> Mix it (maybe you get a twister) 

On a cold day you will re-use more warm air (more circulation, less cold new air).
On a hot day the air will be to hot from inside, you always will get fresh air.

Well - you need ...
temp measurement
airflow control to regulate which air you need more and less for openening a cold air valve or closing the warm air circulation etc.
(reducing the fan speed or increasing the fan speed could work too for each valve/line)

But in case of power interruption maybe some warm air from inside the house would help. (3th valve)
But it wont work automatic without APC/UPS (power is down)
