VRF: An Energy Slashing HVAC System on the Rise 

Variable Refrigerant Flow (VRF) also known as a Variable Refrigerant Volume (VRV) HVAC systems are becoming an important HVAC solution in the U.S. VRF's make up about 24% of the global commercial air conditioning market and over 35% market share in China, India, and Eastern Europe. USA only represents about 3% of the market, but it is growing rapidly with multiple manufacturers like LG, Daikin, Carrier, Mitsubishi and Sanyo.

A VRF system allows one outdoor condensing unit to be connected to multiple indoor fan-coil units, each individually controllable by its user, while modulating the amount of refrigerant being sent to each evaporator. By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at partial-load conditions.

VRF systems have some distinct advantages over conventional systems but they are not for every situation or  application. Learn more about this growing and innovative HVAC solution and review case studies at the end of the article.   READ MORE HERE

Editors Note: We are seeing greater demand for this technology due to life-cycle cost benefits and occupant comfort benefits that outweigh the higher first-cost
as compared to conventional systems.
Game Changing Technologies:
Transformative Wave's CATALYST Verified as Powerful New Way to Save Energy with Rooftop HVAC Units.

Catalyst Controller Box and Antenna Most commercial buildings are cooled by packaged rooftop units (RTUs), but RTUs have a problem: Their fans run at full power, even when cooling demands are low. A few years ago, retrofit kits - like Catalyst - hit the market. These kits enabled building operators to upgrade their existing single-zone RTUs to variable-air-volume operation with claimed HVAC savings of 25 to 50 percent.

Originally, these claims were greeted with much skepticism, but independent tests keep bearing out vendor assertions. In 2013, US Dept. of Energy's Advanced Rooftop Control (ARC) Retrofit: Field-Test Results (PDF) verified savings and demonstrated that these products- especially Transformative Wave's Catalyst - are ready for prime time.
