Carrier Corp. Breaks Heat Pump Efficiency Ceiling with Variable Speed Technology

Carrier® Greenspeed™ Intelligence Enables Units to Deliver Highest Heating Efficiency Rating of Any Air Source Heat Pump on the Market

INDIANAPOLIS, IND., February 16, 2011 – Carrier Corp., a unit of United Technologies Corporation (NYSE: UTX), unveiled the HVAC industry’s highest efficiency residential, air source heat pump at the Air Conditioning Contractors of America (ACCA) Conference & Indoor Air Expo in San Antonio, Texas. The new heat pump delivers an HSPF heating efficiency rating up to 13, the highest of any air source heat pump on the market, and cooling efficiencies of up to 20 SEER. The innovation behind this advanced heat pump is known as Carrier® Greenspeed™ intelligence and will be available as part of the Infinity® heat pump line, ranging 2 to 5 tons. Carrier Corp., the world’s leader in high technology heating, air-conditioning and refrigeration solutions, improves the world around us through engineered innovation and environmental stewardship.

“Carrier is committed to developing residential heating and cooling products that take innovation to a higher degree,” said Chris Nelson, vice president sales and marketing, Carrier Residential and Commercial Systems. “We are proud our new Infinity heat pump with Greenspeed intelligence will be the highest heating efficiency air source heat pump available. In the 3-ton size, it has 29 to 69 percent higher heating efficiency than any competitive product within the residential, air source heat pump category.”

This new product will give homeowners the comfort of consistent indoor temperatures associated with variable speed technology while reducing their use of fossil fuels and lowering their electric heating costs.

The new line of heat pumps is designed to operate fluidly between 40 and 100 percent capacity while heating or cooling a home. This innovation was made possible by pairing the superior communication ability of Carrier Greenspeed intelligence with a Copeland Scroll® variable speed compressor from Emerson Climate Technologies, optimized specifically for this heat pump. The unprecedented capacity control can match the load in a home during a wide range of conditions. This flexibility allows for improved temperature control and dehumidification as well as enhanced Infinity zoning, regardless of climate. The new heat pump is also capable of maintaining consistent, higher leaving air temperatures even when outdoor temperatures fall into the teens, improving owner comfort. Standard heat pumps tend to have cooler leaving air that cools further as outdoor temperatures decline.

At a 3 ton size and in an outdoor temperature of 17 degrees Fahrenheit, the Infinity heat pump with Greenspeed intelligence can achieve 17 to 86 percent greater heating capacity than standard heat pump products on the market today. This breakthrough product will significantly extend the geographic range for heat pumps to serve as a home’s primary heat source.

“The Infinity heat pump with Greenspeed intelligence is an HVAC innovation in a class of its own,” said Nelson. “It’s just the latest example of how Carrier continues to introduce cutting-edge residential heating and cooling solutions.”

The new line of variable speed heat pumps has distinctive features that will benefit both Carrier dealers and their customers. Dealers will appreciate the ease in installation created by the two-wire control connection to the outdoor unit and Infinity Control diagnostic capabilities. Consumers will welcome the variable speed motor’s lower energy usage and more consistent indoor temperature control all year long.

The heat pump also employs an upgraded Infinity control software package that constantly monitors a wider range of critical system parameters, including suction pressure and compressor temperature. This intelligence helps ensure performance efficiency, optimized comfort and reliable operation 24 hours a day, seven days a week.

“The Infinity heat pump with Greenspeed intelligence is a revolutionary breakthrough for home comfort and advances Carrier’s natural leadership in environmental technologies,” said John Mandyck, Carrier vice president, Sustainability & Environmental Strategies. “Greenspeed intelligence also demonstrates how technological innovation can reduce energy use and carbon emissions, continuing Carrier's long-standing commitment to providing sustainable solutions.”

The new line of heat pumps is currently in the final stage of field testing, with consumer availability scheduled for this summer.
