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.
Mark Kuntz, senior vice president, Mitsubishi Electric US Cooling & Heating Division, shares with our HVAC contractor readers the ductless technology trends he is seeing from a manufacturer’s perspective and what contractors can do to sell the product.
This heavy-duty, hot-dipped, galvanized steel wall bracket is fully adjustable. It features a sliding crossbar, built-in level, and rubber isolation vibration mounts.
The manufacturers provided all of the data included in the product grid as well as the photo feature. Therefore, any questions should be directed to them via the contact information provided in the photo feature section.
VRF systems have become very popular in the commercial market and are expected to gain even more market share in the coming years. Each system type comes with its own unique set of benefits, and as long as building owners and managers remain open minded, they may be surprised at the possibilities now available.
Dozens of major manufacturers are now offering a variety of training options ranging from short online offerings to extensive on-location training in hopes of making ductless HVAC a worthwhile investment for consumers and contractors.
According to Navigant Research, annual revenue from energy-efficient HVAC systems will grow from $17.2 billion in 2013 to $33.2 billion by 2020. With ductless systems set to account for nearly 30 percent of all North American energy-efficient HVAC system revenue by 2020, the market for both single- and multi-zone ductless systems is booming.
While VRF technology has had a strong footprint in Japan and Europe for decades, it’s still maturing and gaining widespread acceptance throughout North America. And as the market matures and evolves, manufacturers are enhancing and improving their ductless offerings, including those featuring VRF technology.
