Answer to Question 1

The refrigerant in the liquid line reverses directions between the heating and cooling cycle. Debris caught by a regular drier would be flushed out when the cycle reversed.

Answer to Question 2

One is to list the sensible and latent cooling values for the coil.
The second is to list the total cooling capacity and the sensible cooling capacity, with the latent capacity being the difference.

The third way is to give the total cooling capacity and give the latent as a percentage of the total.
