There was near unanimity at the IIAR 2015 Conference & Exhibition, which took place in San Diego on 22 - 15 March, that “the times they are a-changin’,” as Bob Dylan sang in the 1960s. Those changes are focused particularly on reducing the ammonia charge in industrial refrigeration, both to improve safety and to avoid the strict regulatory requirements that go into effect for charges of ammonia exceeding 10,000 pounds (4,536 kg). +PHOTOS
The phaseout of R22 is also pushing companies towards low-charge ammonia systems, rather than HFC systems that are beginning to be regulated themselves. "For facilities moving away from R22, low-charge ammonia, along with other natural refrigerant technology, is going to be the best option if they are looking to invest in technology that’s going to service them for the next 20 to 25 years,” said Hamilton. Moreover, he said, “the R22 phaseout is a massive opportunity for the ammonia refrigeration industry to enter new markets.”
In addition to talking about the NewTon, Mayekawa demonstrated how it is moving toward its 100th anniversary in 2024 by embracing “the natural five” (ammonia, CO2, hydrocarbons, water and air) in its technology as a “contribution to society,” said Tomooka. "We are working with end users and contractors to find advanced solutions, not the same old solutions used for the last 90 years.”
