Case Studies


R22 Replacement, HVAC Upgrade, RWE NPower


Airtech decommissioned and stripped-out existing 'R22' air conditioning c/w supply, installation and commissioning of a new 'Energy Efficient R410a' Daikin VRV 3-Pipe Heating / Comfort Cooling System c/w Fresh Air Ventilation.   The system comprised heat recovery condenser units, connected to Daikin above ceiling ducted fan coils, offering greater air distribution and reduced noise levels compared to other systems.

Fresh air was provided by Daikin 'Heat Recovery Ventilation' units interfaced with the air conditioning system for total control.  This reduces the load on the air conditioning system and in turn, conserves energy.  A remote stop / start interface was also included.

Local control was provided to serve all cellular areas and a BacNet Interface for connection to an existing Trend BMS was provided to serve the open plan areas; allowing full control of the air conditioning system via the Trend system.

All indoor units fan coil units were provided with individual room sensors.
