International. Johnson Controls announced the launch of its new generation of York VRF GEN II variable coolant flow system which is now available for the Latin American market. The new equipment offers significant improvements including the following:
- Outdoor units redesigned to deliver 26.5% higher efficiency compared to the previous generation.
- Adding 20, 22 and 24 HP base modules in a single enclosure.
- Indoor units type mini cassette 4 ways from 0.5 to 2 tons of refrigeration.
- Expansion and control kits for air handlers from 1.5 to 15 tons of cooling.
- Multi-port heat recovery boxes of 4, 8, 12 and 16 outputs.
- New BACnet interface with the largest monitoring and control capability on the market.
Additionally, the new York VRF GEN II also offers:
- Inverter compressor with 13 new components and intelligent control that improves frequency modulation accuracy in increments of +/- 0.1Hz to reduce energy consumption.
- The compressor muffler chamber and fan blades have been redesigned to provide a better comfort experience, substantially reducing the noise level of the outdoor unit and contributing to stable system operation.
- Greater range for pipe installation in vertical paths between the farthest indoor unit and the outdoor unit of up to 110m, helping with this to reduce the design time of the systems and improving the application of the system in high-rise buildings.
- Ease of maintenance and installation: the distribution of the internal components of the outdoor unit allows sufficient space to facilitate maintenance and installation work. The installation and service technicians have a 7-segment screen that will help them and facilitate them to perform boot tests and system diagnostics in case of failures.
To provide a real connectivity experience, the VRF Smart Gateway control device (BACnet™ interface) completes the package offering unparalleled system control. With the new interface, data from the VRF system is easily and quickly integrated into the Central Building Automation Systems via the BACnet communication protocol, allowing owners unprecedented control and monitoring of the different systems installed in their building, all under one platform.
