From a microscopic viewpoint on the role of two kinds of hydrogen bonds, antiferroelectric phase transition in NH 4 H 2 PO 4 is re-examined. The role played by the protons of NH 4 ions is explicitely taken into account, and it is shown that the hydrogen bonding effect of NH 4 ions with neighbouring oxygens may be renormalized into the effective antiferroelectric interaction between protons which form the network of hydrogen bonds connecting PO 4 groups.
