What is a Variable Refrigerant System?
VRF (Variable Refrigerant Flow) systems are highly engineered, with single or multiple compressors, multiple indoor units (ducted and non-ducted types), and oil and refrigerant management and control components. VRF provides flexibility by allowing for many different indoor units (with different capacities and configurations), individual zone control, and the unique ability to offer simultaneous heating and cooling in separate zones on a common refrigerant circuit, and heat recovery from one zone to another. Typical Capacities for VRF system components range from 18,000 Btu/h to 500,000 Btu/h (5,300 W to 147,000 W) for outdoor units and from 5,000 Btu/h to 120,000 Btu/h (1,500 W to 35,000 W) for indoor units.
VRF systems have started to make a very BOLD statement in the HVAC Industry throughout the United States. The technology has been around almost three decades and has only been used in the U.S. for about 8 years.
What is a GHP?
In 2009 a VRF system powered primarily from natural gas was released into the U.S….giving engineers, architects & design build contractors one of the most efficient HVAC systems to offer to their customers, a gas-fired heat pump (GHP).
What are the benefits of GHPs compared to conventional HVAC systems?
A Gas-Fired Heat Pump (GHP), with its Load Matching Technology, affords the end user up to a 94% Peak Power Reduction and reduces the HVAC electrical infrastructure on new construction as much as 70%.
The U.S. is experiencing a serious energy crisis as well as a serious shortage of water throughout the Country. With the abundant supply of Natural Gas that is now available in the U.S., Gas-Fired Heat Pumps (GHPs) offer a BIG part of the solution for this Countries Energy needs!
With the current Mandates set upon the Government Installations and School Districts, the GHPs offer the end users a Highly Efficient System without the cost of upgrading the existing electrical infrastructure; it actually gives back a significant amount of the buildings load to use in other areas needing to be upgraded…only now at no cost.
