2014 AHR Expo: HVAC Residential Equipment
The NEWS was very busy at the AHR Expo in New York City, visiting as many booths as possible in search of new products. Below is a comprehensive list of all the HVAC residential equipment we found on the show floor.
Air Major Co. Ltd. debuted its AIRREX portable heat pump system that can be utilized in year-round applications. Heat pumps have the ability to move heat energy from one environment to another, and in either direction. Portable heat pumps by AIRREX have the ability to be switched from cooling mode to heating mode. In cooling mode, a heat pump works the same as an ordinary air conditioner. In heating mode, the unit absorbs the heat from the refrigeration cycle and converts it into warm air. The portable heat pump system features a four-way reversing valve, condensate tank LCDI protection, digital controls, and a louver grille.
Aprilaire announced major enhancements to its whole-home dehumidifier lineup. From an application standpoint, the new models are smaller and lighter, yet higher in moisture-removal capacities. This translates to contractors being able to provide better efficiency in tighter spaces like crawlspace openings, HVAC closets, condos, and townhomes. According to the company, efficiencies have improved by as much as 10 percent, with available capacities of 70, 95, and 135 pints per day. On the installation front, enhancements include digital setup, so no dip switches are required, and there’s no p-trap to install. Integrated backflow dampers convert to top or side discharge, and a control panel can be accessed from either the top or front of the unit.
Bard Mfg. Co. Inc. showcased its Geo-Delta water-to-water geothermal heat pump. Suitable for ground-water or ground-loop applications, the Geo-Delta offers many hydronic options, such as radiant floor heating, domestic water heating, and snow/ice melt.
