AET Flexible Space underfloor air conditioning systems have been installed at more than 100 sites across the UK, some of which date back to the mid 1990s. A number of these have required minimal upgrades or modifications to the original equipment specification, but recent developments in controls and communications components have led to significant improvements in the functionality of equipment and subsequently full systems.
Clients such as Jaguar Land Rover, Tag Farnborough and Bloomberg have all opted to upgrade their existing systems with AET. After performing full-system surveys, it was clear that major controls upgrades would enhance the operation and energy efficiency, thereby reducing the systems’ running costs. With services typically accounting for 50% of a building’s operating costs, this has significant financial implications over the long term.
During major controls upgrades, redundant macroface PCB are removed from the CAM and replaced with the latest macroface processor (flexface) and digital expansion PCB. The original hiromatic visual display units that allow access to the flexface are replaced with the latest flexmatic visual display units. The flexmatic can monitor up to 16 CAM units, or eight if the system is configured with an external building management system (BMS).
Fatronic controllers integrated into fantile units can be upgraded to the latest model to ensure full compatibility and functionality. These have been developed alongside the fantile to meet the demanding energy efficiency targets in the current office markets. The controller now offers functions to operate AC or EC fans with 0-10V adjustment of fan voltage for EC fan control, minimum fan speed setting for heating, a run-on feature for electric heating and setting of master/slave function, among others.
Communications modules are upgraded from the pre-existing hirolink modules and replaced with flexgateway for Modbus modules, enabling the AET Flexible Space system to successfully communicate with principal house BMS such as that offered by Trend and other leading manufacturers. Flexvisor remote monitoring using an IP address is also available, allowing users to easily adjust the system for optimum operation. AET’s specialist service and maintenance team can recommend bespoke upgrade options depending on the original installation specification and current use of the space. Contact us for more details.
