I've moved into a new home last year. One attached room is a workshop with a drop ceiling and it was comfortable at around 70 degrees last summer with the air conditioning. This year, I moved a piece of equipment in there and had to removed a section of the ceiling to accommodate the equipment height as it's about three inches higher. I now have one to two feet of open space around the equipment.
It got into the 80s yesterday and the room got quite warm, about 75F. I assume it was because I removed part of the ceiling which lets the much warmer air above it to filter down to some extent.
I'm trying to find something to put over the space in the ceiling. I can't build anything permanent cause I need access to the top of that on occasion. I'm thinking I could make a light frame of sorts that could lay up there but what would I put in it to keep it easily movable and not too awkward? I can't just throw insulation up there cause I can't worry about fibers from that.
Or is there a better idea? Of course, I don't want this to be expensive either.

Without more information or a photo, my answer is to purchase a replacement ceiling tile, cut it to fill your gaps, put the original tile you removed in storage so you will have it if you move out of the space.
