Daikin Applied today unveiled an improved Navigator WWV water-cooled screw chiller using low-GWP R-513A refrigerant.
In addition to providing industry-leading performance, users may combine the new chiller with an optional Templifier TWV water heater for an energy- and cost-efficient heat recovery system. The combination of a low-GWP refrigerant and heat recovery arrangement enables building owners and operators to reduce utility costs while also accelerating their sustainability and decarbonization initiatives.
“The Navigator WWV-Templifier TWV pairing delivers the high-quality performance the industry has come to expect with all-electric heat recovery to decrease onsite emissions,” said Jim Macosko, Daikin Applied’s vice president of product and sustainability solutions. “With the call to decarbonize HVAC expanding and growing louder, Daikin’s continued innovation and enhancements allow our customers to meet the moment, optimizing the environment and their operations.”
Heat Recovery Solution
The Templifier TWV technology enables the Navigator to collect enormous amounts of heat that is normally rejected from the building and use it to generate hot water up to 140°F for processes or personal use. In addition, the Templifier can be used to supplement heat pumps in buildings. This is consistent with the electrification trend occurring in North America and around the world, as both the public and private sectors decrease fossil-fuel combustion for heating and cooling facilities.
The Navigator heat recovery package not only has major environmental benefits, but it may also boost energy efficiency and save utility costs for both HVAC and process applications, with a payback as little as one year.
Quiet and Dynamic Performance
Navigator WWV’s one-of-a-kind single-screw design with variable volume ratio (VVR) compression technology enables greater part-load efficiency and noise reduction.
The Navigator, available in capacities ranging from 120 to 300 tons, is designed for high-lift operation, making it excellent for low-temperature operations and ice applications. Furthermore, Daikin VVR technology adapts to real-time building or process demands, resulting in the most energy- and cost-efficient operation conceivable. The dynamic adaptation to shifting heating and cooling demands ensures appropriate temperatures, humidity levels, and noise.
Climate-conscious refrigerant
The low-GWP refrigerant R-513A replaces the industry standard R-134A in Navigator WWV, providing a more efficient solution for water-cooled screw chiller technology. R-513A has half the GWP of R-134A, lowering the warming impact per pound of refrigerant. R-513A is used proactively to meet standards in numerous states that mandate low-GWP refrigerants.
