Mitsubishi Electric VRF Water Source Units are Smaller, Lighter, More Efficient

Monday, May 24, 2010

SUWANEE, Ga., May 24, 2010 - Mitsubishi Electric Cooling and Heating Solutions (Mitsubishi Electric) has recently updated its CITY MULTI® Variable Refrigerant Flow (VRF) WR2- and WY-Series Modular Water Source Units. Both the WR2- (heat recovery) and WY-Series (heat pump) are available in smaller and lighter units with plate type heat exchangers and both systems operate in either cooling or heating modes.

"The updated WR2- and WY- Series units are designed for buildings with closed boiler water tower or geothermal loop systems," says Meredith Emmerich, director of application support, Mitsubishi Electric. "The W-Series units can be installed inside, rather than outside a building due to its smaller size. This series uses the efficiency of water as a heat exchange medium combined with Mitsubishi Electric's proprietary INVERTER-driven compressor, which effectively uses energy to provide optimum comfort in all connected zones."

The WY-Series is available up to 30 tons and can connect to up to 50 indoor units, while the WR2-Series is available up to 20 tons and connects to up to 50 indoor units as well. Both systems feature expanded entering water temperatures of 23 to 113 degrees Fahrenheit.

The W-Series units can be installed floor by floor inside a building, easily offering a solution for building managers who need to install equipment indoors. Refrigerant, water and electrical connections on the front of the units allow side-by-side installations or stacking with the proper structural support.

The WR2- and WY-Series systems can be connected to any of the CITY MULTI indoor units and can be operated and managed with the CITY MULTI Controls Network (CMCN), which offers a variety of tools and software applications to provide local and centralized control over a building's HVAC systems.
