World's Most Intelligent Variable Refrigerant System


  JAKARTA, August 26 - Adding to a 100-year legacy of innovation pioneered by Dr. Willis H. Carrier, its founder and the inventor of scientific air conditioning, Carrier Corporation announced a new technology today that will set a new benchmark for variable refrigerant system.
Following five years of research and development, including hands-on technical input from the Toyo Carrier design team, PT Sarana Aircon Utama , Carrier main distributor for Indonesia region will begin selling the new IVRS this month.

At today's launch event, here, Mr. Steven S. Tanoto, director of PT. Sarana Aircon Utama, said, "This new IVRS innovation will create industry-leading features that not only enhance the system design but also th e installation flexibility. Older generation Variable Refrigerant Systems have a 15 meters height restriction between the upper and lower most indoor unit, but with the unique Carrier IVRS can have one system handling a height difference up to 30 metres."

The IVRS technology represents another industry first, according to Mr. Tjahjadi Djaja, sales manager. "It's the first time that pressure and heat sensor controls, inverter technology, and three stage oil balancing variable has been integrated into a refrigerant system and controls design as a standard product. The result is the optimization of efficiency across the entire operating range, increased reliability, as well as reduced system complexity and cost."
Once commercialized, the new IVRS technology will produce units that deliver the following customer benefits:
Five outdoor units can be connected into a single refrigerant circuit. Total capacity of 46 HP with variable speed inverter control can be acheived, resulting in better utilization of outdoor space.

Modular outdoor units are compact enough to be carried in an ordinary elevator and outdoor units can be coupled together to minimize installation space. These capabilities are ideal for refurbishing works.

The IVRS can have one system handing a height difference up to 30 metres. All floors in an eight-story building can be air-conditioned with a single circuit. This features reduces piping works, piping space and installation time.

The four-sided heat exchanger, two in one compressor pack and smart sensor controls allow the IVRS to achieve a superior efficiency that is among the best in the market.

Working with the United Technologies Research Center (UTRC) and its strategic partners, Carrier started development of the IVRS technology five years ago, with the goal of bringing exceptional performance at an affordable price to its commercial customers.
"We are confident that IVRS technology units will set the standard for innovation and large commercial customer value for many years to come," Steven S Tanoto added.

The units produced with the IVRS technology will be the latest product addition to Carrier's "E 3 Solutions" HVAC systems. The E 3 Solutions are those systems that provide significant improvement in energy efficiency, environmental impact and economy, or customer value. To assist customers in making progress on global warming, ozone depletion and return on investment, Carrier is providing leadership on all product fronts, from small commercial rooftop air conditioners to vertical package units and water source heat pumps to the largest centrifugal chillers.

Celebrating 100 years of innovation and the invention of modern air conditioning by its founder, Willis Haviland Carrier, Carrier Corporation is the world's largest manufacturer of heating, air conditioning and refrigeration systems and equipment. It is a subsidiary of United Technologies Corporation (NYSE:UTX), provider of a broad range of high-technology products and support services to the aerospace and building systems industries.
