As Variable Refrigerant Flow HVAC Demand Increases, so Does Building ROI1/4/17
Variable Refrigerant Flow (VRF) is a HVAC technology that uses refrigerant as the heating and cooling medium. And, although this technology has been used worldwide for more than 30 years, it is just now coming into popularity within the U.S.
A recent article from FacilitiesNet.com cites multiple reasons for VRF’s new status as the fastest growing segment of the U.S. HVAC market:
- The ability to simultaneously heat and cool a building.
- The ability to vary motor speeds and refrigerant flow.
- The availability of flexible control and multiple zones.
- The flexible design options for new and retrofit buildings with and without ductwork.
Overall, these reasons and many others are leading to a more individualized approach to heating and cooling buildings, while also increasing energy efficiency, resulting in an increase in return on investment (ROI). In fact, Energy Manager Today notes that HVAC systems represent about 41% of the total energy used by commercial buildings; so by installing more efficient systems, the amount of resources used to run a building can be significantly reduced.
For even further energy reductions and improved ROI, many commercial buildings are installing gas powered VRF systems such as YANMAR’s Gas Heat Pump, which utilizes around 90% less electricity, while still offering the same benefits and more as similar electric powered systems.
