Bryant Heating and Cooling Systems said the duct-free units in its Streamline Series are designed to provide both cost and application flexibility for consumers, contractors, builders, and engineers. Streamline highwall units are available in 18,000-Btuh, 24,000-Btuh, and 36,000-Btuh capacities. The company said these enhance the current product offering of in-ceiling cassettes offered in 18,000-Btuh to 36,000-Btuh capacities and under-ceiling series from 18,000-Btuh to 60,000-Btuh capacity levels.
Highwall units in the Streamline Series are available in capacities from 18,000 Btuh to 36,000 Btuh. The under ceiling/console Streamline Series units are offered in the 18,000 Btuh, 24,000 Btuh, and 30,000 Btuh capacity levels. The duct-free units can be used in a wide range of commercial applications, including office buildings, technology facilities, schools, and health care institutions. Carrier said its units have residential applications, too, as they can be zoned for targeted heating and cooling needs. Also available is its I-Sense remote control. This wireless, infrared smart remote is designed to allow the desired temperature to be programmed into the remote, so the temperature can be adjusted to meet the needs of the area around the remote and not the stationary unit, the company said.
The company said its advanced VRV-SÂ® enables precise temperature control for each individual zone (up to five zones). Each in-door unit has an electronic expansion valve that is designed to continually control the flow of R-410A. According to the manufacturer, as climate, lighting, and occupancy cause temperature and humidity fluctuations, the VRV-S inverter-driven compressor continually adjusts to maintain the desired comfort level to within 1.0Â°F of the set point. The VRV-S is available in three-ton and four-ton models, one-phase power supply, and offers refrigerant piping lengths of up to 1,000 feet.
EMI said its new C2C 13-SEER single-zone condenser is the backbone to its new line of 13-SEER products. According to the manufacturer, features of its C2C condenser include an attractive, durable cabinet design for quiet, reliable, and long-operating life; durable compressor; unique U-shaped coil designed to allow for maximum heat transfer surface with the smallest footprint for optimum efficiency; and a two-piece "clam-shell style" fan/motor. EMI added that the permanent split capacitor (PSC) motor provides added starting torque, "enhancing overall system efficiency by reducing power consumption."
The company said its new Ductless mini-split air conditioner is "an affordable and economic air conditioning solution," particularly in older homes, where it can be more difficult from a structural standpoint and more costly to install ducted central air conditioning systems. The system features a rectangular wall-mounted indoor unit with a separate compressor section. The units provide a four-way air discharge deflection and air swing control, allowing the user to position the airflow for better air circulation and cooling. The unit features an anti-mold blower wheel and washable filter, an easy-to-read LED display, and a 24-hour timer. Units range from 9,000 Btuh to 22,000 Btuh.
