Project
simultaneously in both heating and cooling modes . This feature significantly enhanced occupant comfort , as each individual could easily adjust the temperature according to their preferences . Moreover , the heat recovery capability contributed to the overall energy efficiency of the building , aligning perfectly with the Greenstar requirements .
For the VRV heat recovery system , Samsung ’ s DVM S product line , utilising a three-pipe design for enhanced heat recovery and energy savings , was employed . The outdoor units were strategically placed on the building ' s plantroom located on the side of the building , between the first and second floors , with refrigerant piping running through dedicated shafts to the respective floor zones and distribution ( MCU ) boxes , from which they supplied conditioned air to individual units . The hermetically sealed inverter compressors and R410a refrigerant added to the system ' s energy-efficient operation .

“ To cater to Primedia ’ s needs , GPCE introduced an innovative Variable Refrigerant Volume ( VRV ) system , designed to efficiently cool each of the building ’ s four floors .”
Typical VRV indoor unit application .
