McQuay International: Water-Source Heat Pumps
The Enfinity™ console water-source heat pumps, designed for in-room installation, exceed ASHRAE 90.1 efficiency standard by up to 35 percent to reduce energy consumption and operating costs, says the company. Selectable for standard, boiler/tower or geothermal applications, the water-source heat pumps use R-410A refrigerant. Available in a range of colors, the flat- or sloped-top cabinet has one front and two side panels to allow easy access to water connections, components, and controls, helping to reduce installed and maintenance costs. The console unit’s GentleFlo™ cross-tangential fan wheel delivers maximum airflow required for proper air circulation along with whisper-quiet operation. The heat pumps are equipped with a MicroTech® III unit controller with the Open Choices™ feature to allow stand-alone thermostat operation for easy, low-cost integration with any building automation system using LonWorks® (LonMark® 3.4 certified) or BACnet® communications. A variety of factory-installed piping and valve packages can be selected to further simplify field installation and reduce labor costs. Units are equipped with a removable, noncorrosive polymer drain pan that promotes positive condensate drainage for IAQ. Optional closed-cell insulation is available for sensitive applications to prevent insulation fibers from entering the supply airstream.
