Ductable Split Unit

Ductable Split AC Systems

Ductable split units combine the efficiency of a centralised system with the flexibility of split AC. The indoor unit is concealed in the false ceiling with a duct network distributing conditioned air through grilles and diffusers — ideal for restaurants, small offices, retail shops, showrooms, and conference halls.

Sreewari Engineers provides complete ductable split unit solutions from leading brands including Daikin, Carrier, Voltas, and Blue Star, ensuring quiet operation, even air distribution, and low maintenance requirements.

Ductable units provide uniform cooling across entire floor spaces without visible indoor equipment, maintaining a clean aesthetic.

Duct Design & Air Distribution Engineering

Low-leakage, high-velocity and low-velocity duct networks optimised using the Static Regain Method for balanced static pressure and uniform air distribution.

Static Regain Method Design

Duct networks designed using the Static Regain Method ensure that static pressure is maintained at each branch takeoff — eliminating over/under-cooling of spaces and reducing fan energy consumption.

  • Equal pressure at all supply outlets
  • Reduced total fan static pressure
  • ASHRAE Handbook HVAC systems reference
High & Low Velocity Systems

Low-velocity duct systems (max 5 m/s) are specified for noise-sensitive office environments; high-velocity systems reduce duct cross-section for long runs in restaurants and retail spaces.

  • NC-25 to NC-35 noise criteria compliance
  • Acoustic lined ducts where required
  • GI sheet gauge selection per SMACNA
Air Distribution Excellence

Supply diffusers, return grilles, and VAV boxes sized for optimal throw patterns, minimising drafts and stratification while achieving ASHRAE 55 thermal comfort standards.

  • Swirl, linear & jet diffuser selection
  • Throw & drop calculations per ADC manual
  • VAV box sizing for demand-based ventilation
Commissioning & Air Balancing

System commissioning per ASHRAE Guideline 1.1, pressure testing for Leakage Class C compliance, and air balancing reports ensuring every outlet delivers its specified design airflow.

  • Duct leakage test at 1.5× design pressure
  • Certified TAB report on completion
  • O&M manual & as-built drawings
