Thank you for this comment! Especially for super-resolution this is a good option.

> Our room has 3 microscopes (2 confocals and one SIM) and 2 computer work stations. We have cool air coming in form above, which alone kept the room at 71.0oF +/- 1.5oF. To reduce the temperature oscillations more (which can cause the optics to creep out of alignment) we added two floor HEPA filters that pull air in from the sides and blow it up. This was a win-win, because they've reduced the dust load in the air but also continuously push the cool air back up, keeping the room at precisely 72.0oF +/- 0.3oF (we also have a datalogger to continuously monitor temperature swings). Another consideration is to also be sure to keep humidity between 20 and 60%.

> Dear all,

> Around the end of 2018 our light microscopy facility will move into a new building. Even though the date of the move is still quite far in the future, I have to provide the planners with numbers. Whereas the number of electronic and internet plugs as well as IT connection speed etc is no problem, it seems to be quite difficult to find an adequate solution for room cooling / air conditioning.
> I searched the list for the topic and only found a thread from 2009. As this is a quite important issue for any microscopy facility, I’d like to take the opportunity to ask for some feedback and if possible images of your solutions. All comments on what to do and what definitely not to do are very welcome!

> The new Biozentrum building will be a low-energy-consumption building (Minergie:
http://en.wikipedia.org/wiki/Minergie) which means that there will only be a minimal exchange of air in the rooms.
> The new rooms will be approx. 20sqm large (215 square foot) and I am planning to put 3 systems max. into each room. A confocal with an argon laser generates approx. 4kW, so in a worst case scenario we will have to be able to cope with 12kW/room. Referring to this calculation, I told the planners that we will need 15kW of cooling capacity per microscope room.
>
> So far the planners offered 2 solutions for cooling:
>
> 1) the conventional convection cooling solution: 3 big boxes at the ceiling, each with a center inlet and 4 surrounding lamellar outlets
> => very loud, cool air “falling down”, difficult to reach homogeneous temperature distribution.
>
> 2) a more sophisticated version: based on roller-type fans with long textile tube outlets
> This solution can be combined with a diffusor covering the entire room ceiling thereby providing a more homogeneous air distribution and less noise.
> However, to accomplish this, we will have to agree to a room height of 230cm (7.55ft). Except for our 2PH system this should not be a problem.
> I think that solution 2) could be a reasonable solution.
>
> Please let me know how you solved your room cooling, especially in relation to low-energy-consumption buildings with little air volume exchange.
