HVAC Systems & Accessories
BEE-Rated HVAC Systems for Residential, Commercial & Industrial Projects
HVAC (Heating, Ventilation, and Air Conditioning) systems are critical infrastructure in modern buildings, directly impacting occupant comfort, indoor air quality, and energy costs. From inverter split ACs (BEE 5-star) for residential units to VRF/VRV multi-zone systems for commercial towers, centralized chiller-AHU-FCU systems for hospitals and IT parks, and precision air conditioning for data centres, the right system selection must align with ECBC 2017 energy code compliance and occupant load requirements. Buildigo connects builders, MEP consultants, and contractors with verified HVAC suppliers. Share your cooling load, system type, and BEE rating requirement to receive competitive project quotes.
Types & Grades
Types of HVAC Systems
Inverter Split & Multi-Split AC
Residential and light commercial cooling for individual rooms. Inverter-driven compressors modulate capacity from 30–100% of rated output, reducing energy consumption by 30–50% versus fixed-speed units. BEE 5-star inverter split ACs achieve ISEER values of 5.0+ (1.5 TR). Cooling capacity: 0.75 TR to 2.0 TR per indoor unit.
VRF / VRV Multi-Zone Systems
Variable Refrigerant Flow (VRF) systems connect multiple indoor units (2–64 per outdoor) via refrigerant piping with individual zone temperature control. Heat recovery VRF systems simultaneously cool and heat different zones, recovering waste heat with COP values of 3.5–5.0. The preferred choice for commercial offices, hotels, and multi-zone buildings.
Centralized Chiller + AHU + FCU Systems
Water-cooled or air-cooled chiller plants for large commercial buildings, hospitals, and IT parks. Chiller COP: 4.0–6.0 for centrifugal; 3.0–4.5 for screw chillers. Chilled water (7°C/12°C supply/return) is distributed to Air Handling Units (AHUs) for large zones and Fan Coil Units (FCUs) for individual spaces. 4-pipe systems allow simultaneous heating and cooling.
Precision Air Conditioning (PAC)
Close-control precision AC units for server rooms, data centres, and telecom installations requiring ±1°C temperature and ±5% RH humidity control. CRAC (Computer Room Air Conditioning) and in-row cooling systems for high-density server racks.
Ventilation & Fresh Air Systems
Fresh Air Handling Units (AHUs) delivering ASHRAE 62.1-compliant outside air per occupant (typically 10 cfm per person). Energy Recovery Ventilators (ERV) recover 60–80% of exhaust air energy. Exhaust systems for kitchens, bathrooms, laboratories, and parking areas.
