TFI – Australia’s First Heat Pump

Cold Logic is committed to being at the forefront of refrigeration technology – bringing together the leading products from suppliers across the globe with expert local refrigeration design and engineering experience in all facets of applications.

Cold Logic has installed Australia’s first Ammonia Heat Pump (AHP) at Thomas Foods International (TFI) that turns waste heat rejected from refrigeration plant into 75°C water to offset boiler use. The project was undertaken at TFI’s Lobethal Abattoir in South Australia.

The basic concept of the AHP works on the basis that discharge gas from the high side of the ammonia refrigeration plant is drawn and recompressed by a high pressure compressor. This elevates the pressure and increases the temperature which in turn is passed through a heat exchanger where it transfers its heat to water on the other side.
