Carrier Corp. on Sept. 16 celebrated International Day for the Preservation of the Ozone Layer, designated by the United Nations General Assembly to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer.
The Montreal Protocol is viewed as one of the most successful environmental treaties as it set in motion the global phase-out of ozone depleting substances such as chlorofluorocarbons (CFCs) and hydro chlorofluorocarbons (HCFCs) used as refrigerants. Sources from Carrier report that Carrier pioneered the phase-out of CFCs for the air conditioning and refrigeration industry in 1994, two years ahead of U.S. requirements and 16 years before mandates in developing countries.
Carrier has continued to develop cutting-edge sustainable products and solutions and has been recognized for its leadership in environmental stewardship.
“Carrier is proud to have done its part in leading the air conditioning and refrigeration industry to a non-ozone depleting future,” says Geraud Darnis, president of Carrier Corp.
“The discovery of ozone depletion and the rapid response by governments and industry around the world are widely credited with averting a global environmental and health crisis. Today we celebrate the commemoration of the signing of the Montreal Protocol,” says John Mandyck, Carrier’s vice president for Sustainability & Environmental Strategies. Carrier continues its commitment to sustainability and a non-ozone depleting future with the development of next generation systems using refrigerants that further reduce environmental impact.
The company’s PrimeLINE® container refrigeration unit is an example of this innovation -- designed specifically to reduce environmental impact and lifecycle cost through exceptional efficiency. The PrimeLINE unit’s lifecycle cost is up to 30% lower than all competitive units, sources say. The reduced power requirements also help conserve precious fossil fuel, lowering particulate and carbon dioxide emissions. The PrimeLINE unit has the highest deep-frozen capacity of any unit using R-134a, the non-ozone depleting refrigerant with the lowest global warming potential of all contemporary container refrigerants. As Carrier works to develop new products, the company remains focused on the core value of environmental stewardship. As an example, Carrier has pushed the performance of its residential air conditioning Infinity™ Series, with Puron® non-ozone depleting refrigerant, to 21 Seasonal Energy Efficiency Ratio (SEER), requiring 40% less energy to operate than today’s minimum efficiency systems.
Commercial building owners also turn to Carrier to provide energy efficient sustainable solutions. As an example, to optimize energy consumption, the ITC Hotel Royal Gardenia in Bengaluru, India required the most efficient chiller systems that would meet the demands of the local climate and the challenging energy needs of a hotel. The ITC Royal Gardenia selected Carrier’s world-leading Evergreen® 23XRV chiller with non-ozone depleting refrigerant.
The Dalian Wanda Group, a renowned real estate enterprise in China, recently awarded a chiller purchasing contract to Carrier to supply up to 300 energy efficient chillers with non-ozone depleting refrigerant.
As part of its commitment to improving the environment, Carrier recently signed a supply agreement with Handelshof Cash & Carry, a German food retailer, for the delivery and service of a CO2OLtec™ refrigeration system as well as a fully integrated high efficiency heat recovery system, which will reduce heating energy consumption by 80 percent. The state-of-the-art refrigeration system using CO2 refrigerant significantly reduces greenhouse gas emissions. The CO2OLtec food retail refrigeration system uses natural refrigerant carbon dioxide and is installed at more than 140 sites across Europe.
The CO2OLtec system delivers up to 10% higher energy efficiency in cooler climates compared to systems using conventional refrigerants. Carbon dioxide as a refrigerant is non-ozone depleting with minimal global warming potential. “Carrier has the right refrigerant solution for every application, but every application will not have the same refrigerant solution,” Mandyck adds. For more than 20 years, Carrier has led with sustainable solutions to advance energy efficiency and ozone protection, while minimizing the environmental impact of its manufacturing operations.
“Carrier will continue to serve as an environmental steward, finding both large and small ways to make the world a better place to live. The company is focused on delivering environmentally responsible energy efficient systems, services and solutions to the world,” Mandyck says.
