A method and apparatus to improve the efficiency of a heat exchange system comprising a compressor condenser expansion valve an evaporator and an expansion valve are provided. The apparatus is positioned between the expansion valve and the evaporator and comprises an atomizing disc an outer connector pipe and two inner pipes inside the connector pipe in contact with the disc. The disc is provided with vertical blades that are angled to provide the turbulence necessary to create a low pressure at the back of the disc. The low pressure thus created vaporizes the partially vaporized incoming refrigerant from the expansion valve and thereby improves the efficiency of the refrigeration system.
