Thanks dogman I will try this as well, but I am still not sure even summer bypass mode will be enough to keep the flat cool or not

well, I am still hoping there might be a better solution than running a portable ac and putting ear defenders :))

Thanks guys for the answers, @le-cerveau Yes it is integra model, but it is 55x55, and 30 deep, 10 cm for the hose extensions as well so it is 75 length, but the void is big, there is space to fit sth if the deep is 30 the building is a well-known building and developer installed a comfort cooling system only 36+ floor above flats @Declan52 windows already have reflective film from outside I belive, well maybe not a film but it has sth because when you look at the windows from outside you cant see inside unless there is light inside and its night, during the day you can not see inside from outside so I suspect it has some reflective structure already but not sure, also I am on 25th floor and there is no balcony, I can not install anything from outside, is there any reflective film which I can install from inside? @Nickfromwales thanks Nick, I have a portable AC, i use that during hetwaves and my vent doors inside the flat can not be opened much but I put it through the vent doors as in the picture attached, but the problem is portable AC is so noisy, you can't sleep while it is running, well at least I cannot

Hello guys, I live in London in a high rise building, there are more than 400 flats in the building and most of us suffering from overheating during heatwaves, we have big windows and getting lots of solar gains. My flat is a 1 bedroom flat, 43 sqm2, Flats have vent axia mvhr system installed in the void, which gives clean air to the flat, but it doesn't have summer bypass mode so during summer if outside temperature is lower than inside, this unit still recovers the heat still and inside I can see 30+ celsius temperature easily during sunny days. Because there is no balcony, it is not possible to install a normal AC, some guys in the building installed water cooled AC systems with an internal condenser but it is very costly to install such a system, and you would use only a few weeks in a year. I was wondering, is there any MVHR unit which can replace our vent axia and give some cooling as well? or is there any other way you would suggest us to do? Regards
