As the American market becomes more familiar with variable refrigerant flow (VRF) systems, it’s discovering firsthand the technology’s ability to deliver exceptional comfort with lower life cycle costs. Additionally, contractors are touting the ability to perform maintenance on systems individually, allowing them to fix a problem without disrupting the comfort delivered to the remainder of the facility.
VRF systems can achieve up to 30 percent HVAC energy cost savings relative to minimally code-conventional-compliant systems or older inefficient systems across a range of building types, according to the Pacific Northwest National Laboratory. In addition to energy savings, VRF systems offer flexibility, cost-effective installation, and greater comfort for end users.
The 6-, 8-, 12-, 14-, 16-, and 24-ton VRF heat pump systems feature inverter compressor technology with highly efficient heating function down to minus 13°F ambient air temperature due to scroll compressor and liquid-injection technologies.
