Maybe the person using the Time Turner is just converted to air molecules of the same mass… and in the past, the molecules of air convert to the given person.

So, people are about 700 times as dense as air- a 45 kilo girl will go from occupying about .042 m^3 to about 30 m^3. If done slowly, this isn’t a problem- but if you do the swap instantaneously, you need to have all of those molecules in that small volume. The pressure required (i.e. the pressure that it will expand outward with) without changing the temperature is 700 atm; this is comparable to the maximum chamber pressure of a firing pistol. The overpressure from the Oklahoma City bombing explosion was only about 40% that large.
In the reverse direction, 30 m^3 (the size of a room that’s 12 feet by 11 feet by 8 feet, or a sphere with a 3.1m radius) of air will be required. If done too quickly, this could cause similar problems.
To summarize what Vaniver said: This is exactly equivalent to the person exploding into bits, except with even more pressure and the bits are solid compressed air flying around like shrapnel and killing everyone nearby with sheer pressure.
