Preparation phase
Proficient crane operators executed a safety-assessed procedure to replace worn-out Variable Refrigerant Flow (VRV) systems with new Daikin VRVs.
Our supplier delivered the cassette units in stages to align with the installation schedule.
Our team systematically disassembled the VRFs and cassette units in designated groups, ensuring they were neatly organised for efficient removal.
Installation phase
Installation of VRVs and cassette units
During the installation schedule, the VRV teams and cassette installation teams replaced the units, connecting them to the existing piping and electrical wiring while taking measures to ensure the cleanliness of office spaces.
Compact variants of Daikin cassette units were utilised in smaller spaces to enhance operational efficiency.
Testing & Commissioning
Our team commissioned the Daikin VRVs and configured the centralised controller, and set up the aircon schedule. Subsequently, the team confirmed the airflow readings.
The centralised controller Reiri provides convenient, unified access to and monitoring of all units. Units in each room can also be named for easy reference.
