Residential Air Conditioners and Heat Pumps: Comfortably Cool

Carrier
Carrier Corp. has developed a hybrid heat dual fuel system that features a two-speed, 19 SEER electric heat pump and a highefficiency gas furnace.

The heat pump provides energy-efficient comfort during the cooling season and electric heat during moderate heating conditions. As the temperature drops outside, the system automatically switches to gas furnace heating when gas becomes the most economical heating source. In addition, the hybrid heat dual fuel system uses environmentally sound Puron (R-410A) refrigerant.

Mitsubishi
Mitsubishi Electric HVAC Advanced Products Division has introduced its new hyper-heating inverter (H2i) technology for select Mr. Slim split-ductless and City Multi VRFZ systems.

The patent-pending flash process cools the compressor, which allows for higher compressor speeds at lower temperatures without overheating. This process also increases the mass flow rate in the system to provide phenomenal heating performance at low temperatures.

The Mr. Slim H2i P-Series outdoor heat pump has a 36,000 BTU/h cooling capacity and 38,000 Btu/h heating capacity. The sleek outdoor unit connects to either the P-Series wall-mounted or ceiling-recessed cassette indoor units, which allows added versatility within applications.

Sanyo
Sanyo HVAC’s Mini ECO-i heat pump system is an intuitive system that provides an immediate response to a change in room capacity, heat loads, and varying sun exposure throughout the day, the company says.

Individual comfort zones allow for each room to be adjusted to personalized preferences. Through one refrigerant piping network, units are connected by up to nine fan coil units that use environmentally friendly R-410A refrigerant.

The Mini ECO-i is suited for light commercial and premium residential applications. According to the company, the space-saving design and ultimate efficiency make a smart solution for installations requiring smaller footprints and complete flexibility from restoring historic homes to highend new construction developments.
