Packaging Details :Automation & Smart Control
Modern HVAC systems are often integrated with BMS (Building Management System) or IoT-based smart controllers.

HVAC system is a mechanical and control infrastructure that regulates indoor temperature, humidity, and air quality to maintain thermal comfort and healthy conditions in buildings. It includes heating, ventilation, and air conditioning processesall managed either manually or automatically.

Functions of HVAC Systems
Function Description
Heating Raises indoor temperature using heat exchangers, boilers, or heat pumps
Ventilation Replaces/stabilizes air via exhaust fans, ducts, or fresh air intakes
Air Conditioning Cools indoor air, removes humidity using refrigerants and compressors

Types of HVAC Systems
Split HVAC Systems (Ductless or Ducted)
Separate indoor & outdoor units

Used in homes, small offices, server rooms
leelavati automation
Central HVAC Systems
Uses ducting to supply conditioned air throughout the building

Ideal for large commercial, retail, hospital, or office complexes

VRF/VRV Systems (Variable Refrigerant Flow)
Multiple indoor units controlled by one outdoor unit

Energy-efficient, scalable, zoning capabilities

Chiller-Based Systems
Chilled water plants for large-scale cooling

Used in malls, airports, factories

Packaged Units (AHU + Condensing Unit)
Self-contained units for rooftops or commercial use

Geothermal HVAC
Uses underground thermal energy for heating/cooling

High efficiency, low maintenance
