A method for producing W/O-type suspension may comprise: mixing water and oil to form water-oil mixture; and driving the water-oil mixture in a flow path so as to make the water-oil mixture into W/O-type emulsion in a static electrification condition. The flow path may include a metal heat exchanger. The method may further comprise: adding activity compound of hydrophobic nature into the water-oil mixture, the activity compound having atoms with an electronegativity higher than electronegativity of hydrogen; slowing down the driving of the water-oil mixture in the flow path so as to adsorb the activity compound on the surface of the heat exchanger; and cooling the heat exchanger on the opposite side of the emulsion while circulating the emulsion through the flow path so as to produce W/O-type suspension. The oil and the activity compound are preferably non-cognate.
