H is enthalpy.
U is internal energy.
del sign represent change.
Del H= Del U if Del(P*V)=0.
U is internal energy.
del sign represent change.
Del H= Del U if Del(P*V)=0.

Given that H is enthalpy and U is internal energy and del sign represent change so you will get the Del H = Del U when Del (P*v)= 0 .
Otherwise it is not in this state. Hope this answer is provide clear understanding for the student who have no trouble among them so it will be more comfortable in a fine manner.
