GOLD: Tranquility22 Digital SeriesThe Tranquility22 Digital is a new geothermal heat pump that is the first in the industry to integrate digital communicating controls, two-stage capacity, variable-speed fan and variable-flow geothermal source functions within a single compact plug and play package, according to the company. The Tranquility22 Digital is a packaged water-to-air system that provides high efficiency heating and cooling and, via an integrated de-superheating package, most of the annual hot water requirement. It meets Energy Star® Tier 3 efficiency levels, so it will qualify for the uncapped 30 percent federal geothermal heat pump tax credit in 2012 and beyond. Tranquility22 Digital systems are available in vertical and horizontal configurations in nominal capacities of 24, 30, 36, 42, 48 and 60 kBtuh. This product line has been specifically designed and developed for price sensitive, and many times space limited, spec home and replacement/retrofit applications.
SILVER: Geothermal RQ SeriesAAON RQ series geothermal rooftop units are engineered for performance, flexibility, and serviceability. Geothermal heat pumps take advantage of the seasonally constant temperature of the earth below ground level to provide year-round energy efficient heating and cooling. Double wall rigid polyurethane foam insulated cabinet construction and direct drive backward curved plenum fans allow the RQ series units to have quiet, energy efficient airflow with high static pressure capabilities. Standard RQ series features include stainless steel piano hinges, color-coded wiring diagrams, labeled components and isolated controls and compressor compartments for ease of maintenance. Available options include high efficiency variable speed fans, variable capacity compressors, energy recovery wheels, and economizers.
BRONZE: LG Art Cool Inverter MirrorThe LG Art Cool Inverter Mirror is an interior heating and cooling system with a stylish black curved-mirror finish. This can be added to a room without the semblance of an air conditioner on the wall. Models range in efficiency from 18.9 SEER to 20 SEER and allow LG to qualify for the Federal Energy Efficiency Tax benefit. This product uses the environmentally friendly R-410A refrigerant. This duct-free single split is enhanced for easier installation; this includes installation support clips that allow for 25 degrees of separation from the wall without detaching the unit. A detachable bottom cover makes installation possible without having to dissemble or support the unit, this also allows for easier access to the unit’s electrical wiring. The new models include a 45 percent wider cavity for piping – compared to conventional inverter units – allowing for easier installation. This inverter heat pump air conditioner uses a variable speed compressor. Instead of shutting off once the desired temperature is reached, the inverter compressor continues to operate at low speed to maintain that temperature.
