Carrier Celebrates the Preservation of the Ozone Layer

Carrier Corp. is celebrating 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. Carrier Corp. is a unit of United Technologies Corp.

The Montreal Protocol set in motion the global phase-out of ozone-depleting substances, such as chlorofluorocarbons (CFCs) and hydro chlorofluorocarbons (HCFCs), used as refrigerants. Carrier was on the forefront of 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. Since then, Carrier has continued to develop sustainable products and solutions and has been recognized for its leadership in environmental stewardship.

Carrier continues to develop next-generation systems using refrigerants that further reduce environmental impact. The company's PrimeLINE container refrigeration unit was designed specifically to reduce environmental impact and life-cycle costs through efficiency. The reduced power requirements help conserve fossil fuel, lowering particulate and carbon-dioxide emissions.

Commercial building owners also turn to Carrier to provide energy-efficient sustainable solutions. To optimize energy consumption, the ITC Hotel Royal Gardenia in Bengaluru, India, required efficient chiller systems that would meet the demands of the local climate and the challenging energy needs of a hotel. The hotel selected Carrier's Evergreen 23XRV chiller with non-ozone-depleting refrigerant. Recently, the Dalian Wanda Group, a real-estate enterprise in China, awarded a chiller-purchasing contract to Carrier to supply up to 300 energy-efficient chillers with non-ozone-depleting refrigerant.

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 refrigeration system using CO2 refrigerant significantly reduces greenhouse-gas emissions. The refrigeration system uses the natural refrigerant carbon dioxide and is installed at more than 140 sites across Europe. Carbon dioxide as a refrigerant is non-ozone-depleting with minimal global warming potential.
