Tips on drying in a heatwave

I have some autos on my balcony that are coming to term/ready to cut, but we're in a heatwave right now. It's around 30c in my drying tent even with the flap halfway open...

I have a small portable AC that's running, but it's just helping maintain the appartment livable while it's 38-42c outside and I can't really get under 28-30c...

Does anyone have some tips on how to dry my buds correctly in this situation or lower the temp of my tent in a heatwave ?
