In addition to low-charge ammonia-only systems, a number of manufacturers at the IIAR (International Institute of Ammonia Refrigeration) 2015 Conference & Exhibition, which took place in San Diego 22 - 25 March, focused on ammonia heat pump technology and ammonia-carbon dioxide solutions that both reduce ammonia and limit it to the machine room. Indeed CO2 is increasingly infiltrating itself into the industrial refrigeration industry, though some players question whether it can wo
With the EPA’s regulations on emissions, [energy-saving] ammonia heat pumps serve that very well,” he said, adding that the ammonia replaces an HFC like R134a. “People in the U.S. are waking up to what we’re doing.”
In the industrial world they want us to sell a compressor package with a controller, oil separator and other accessories,” he said.
Our mission is to make the world a safer place for the people in the industrial refrigeration industry by minimising the risk of exposure to ammonia,” said Bruce Nelson, president of Colmac Coil Manufacturing, Colville, Wash.
In Canadian warehouses, we need heat reclaim applications for heating the shipping docks and higher-temperature rooms,” said Dolbec. The NH3-CO2 systems also enable end users to reduce their ammonia charge.
Guys want to keep ammonia in the engine room and CO2 in the plant,” he said at his IIAR booth. But the change from large-charge ammonia systems will not happen overnight. “It will take 30-40 years to get to that in all new plants.”
