Popular variable refrigerant flow solution across the world
Variable Refrigerant Flow systems (VRF) are quickly becoming popular for air conditioning solutions across the world. VRF systems not only provide flexible and energy efficient air conditioning, but also heating and hot water for residential and commercial applications.
Some of the features of this type of an air conditioning system with variable refrigerant flow include:
- Cooling only, or reversible for heating, including heat recovery options
- Air or water cooled systems
- Variable capacity compressors
- Optimised for a number of conventional and environmental refrigerants
- Up to 64 indoor units with individual metering
Features and benefits
Compact, space-saving components
High energy efficiency
Optimized for environmentally friendly, low GWP refrigerants
Reduced applied costs and short payback times
Dedicated technical and customer service around the world
Eco labelling options
Variable refrigerant flow components in a typical system:
NRV refrigeration check valves
NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with fluorinated refrigerants. NRV and NRVH can be supplied with flare and solder connections. They are also available with oversize solder connections providing flexibility in the use of check valves.
ETS electric expansion valves
ETS is a series of electric expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions. ETS valves are compatible with electronic control solutions from Danfoss and other manufacturers.
