    Using extractor cooker hood/vent for AC extraction



    Hi all

    Have tried to find answer to this else where am not a AC or refrigeration installer. After a seriously hot summer and living in property for last few years that gets seriously warm and humid I'm pretty desperate to find some sort of air con solution. I live in block of flats with large awning windows that don't provide easy aesthetic solution to mobile air con. The other thing I have thought might be solution (See attached photo) is take cooker vent off ceiling and mount air con to wall and vent through this. Is this possible? Would there maybe be an issue with pressure from air con being to much and possibly blowing motor or causing any other issues? Thanks

    Hi

    Do your windows have a lower smaller pane and a larger upper pane?

    If so you can remove the lower pane and cut a paeice of wood or plastic the same size as the pane and cut 2 holes in it and refit it in place of the pane. Then use flexible ducting to supply cooler air and remove the warm air from a portable air con unit to allow it to work in a sealed room, depending on the make.

    It will just be an eysore until you put the pane back when it gets cooler.

    Might be out of your price range, but an option.

    They are single pane windows unfortunately.

    Re: Using extractor cooker hood/vent for AC extraction

    I have and only solution would be the mobile unit sitting above stairs lead across flat and would need to seal window somehow with pvc sheet or something and cut hope in this for hose. All seems like quite extreme measures. There's also the added need to store large sheet and unit in cooler months. Just think all round a wall unit would be better option. Have not had anyone tell me exactly why the hood vent is not a viable option yet?

    Re: Using extractor cooker hood/vent for AC extraction

    The problem with the hood vent is the extra length if duct/hose that this adds to a portable unit.

    You might need to add an extra fan to suck the air from the AC and blow it up the hood vent.

    Something like this maybe, just needs two holes drilling for vents.

    Re: Using extractor cooker hood/vent for AC extraction

    What size are your windows, can you photo them to give us more options? A window unit might be a cheaper option.

    Or maybe this if you have a portable unit.

    Re: Using extractor cooker hood/vent for AC extraction

    Thanks fault code. It is 6 metre minimum to outside vent pipe . Unfortunately Monkey I do not own the property but long time resident and maybe have scope to do minor alterations. That link didn't come thru right Chilly can't follow it. It have included photo of window if anybody has any further suggestions. Thanks

    Re: Using extractor cooker hood/vent for AC extraction

    Its called AC-Airlock universal window seal for mobile air conditioners.

    Its a shame you can't take out that bottom pane and replace it with a plastic sheet and put 2 x vents in it, a bit like the link from monkey spanners.

    The beading looks like its on the outside? It usually pops out by using a quality scraper, but make sure that you mark the beads, upper, lower, left and right, they tend to pop back in easier especially if they're uPVC. Do you know a joiner or someone who's handy that could make you a plastic panel and put the vents in it and fit it for you?

    Re: Using extractor cooker hood/vent for AC extraction

    These can be fitted without the need to go outside. Just use a bit of string wrapped round the outside vent cover, poke it out the hole and then pull it into place. Not quiet as the compressor is in the room but the benefits outweigh the noise. B&q had them years ago air force brand and they were 125 (clearance offer) I got a couple and fitted them for friends. 2x 135mm holes will need making obviously not sure how that would go down with the building owner

    ^^Chilliwilly^^, sadly your plan can't work. Rotate the picture 90 CW.

    @ Faultcode
    Nah, my bet is that the mug/pot is superglued in place and that the blinds are vertical ones.

    On a more serious note,
    This is what standard portable AC units are designed for, the ones with a single hose (elephant's trunk).
    Open the window, poke the hose through the opening and turn the AC on. If you want to upscale it, cut some insulation board (like these) to fit in to the gaps around the hose and tape them in to place to stop warm air getting in to your flat. (Lightweight insulation/styrofoam board, not wooden panels as these might hurt someone if they fall out)

    Thank's for pointing that out Faultcode, I see what you mean, I didn't realise it was taken with the camera rotated until you pointed it out, I can see that the windows and balconies in the background are a dead give away now.

    I suppose the pane at the side could still be removed and apply the same idea, that way no detriment to the construction of the building will be involved, and have to be made good if the tenant leaves. Its just a case of access to the external beads to remove the pane and replace it with a sheet of plastic, or use the AC airlock blanket with 2 openings.

    Re: Using extractor cooker hood/vent for AC extraction

    Thank you everyone much appreciated for all the advice. Does seem like I am quite limited with neat option with acceptable alterations to flat. Have decided to buy pvc sheet cut to length of window. This will slot in grooves and then just cut hole and run hose to this. Won't look great thru summer months but think worth it not to put up with this heat. Hardest bit will be finding somewhere to store giant sized pvc during winter : )

    Re: Using extractor cooker hood/vent for AC extraction

    Personally I would just try connecting the end of the hose to the extractor unit. you could potentially take the extractor out and just use the hose of the outlet.

    Doubt it would cause any issue with the portable ac.
