Ref Desptn HVAC System

We are engaged in manufacturing and supplying of hvac system 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 processes—all managed either manually or automatically.   Functions of HVAC Systems FunctionDescription HeatingRaises indoor temperature using heat exchangers, boilers, or heat pumps VentilationReplaces/stabilizes air via exhaust fans, ducts, or fresh air intakes Air ConditioningCools 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    Main Components ComponentFunction CompressorPressurizes refrigerant to move through the system Condenser CoilReleases heat outside (cooling function) Evaporator CoilAbsorbs heat from indoor air (cooling function) Blower Fan / AHUCirculates air through ducts ThermostatUser interface to control set temperature Ductwork / DiffusersDelivers air to different zones Air FiltersRemove dust and particles from intake air VFDs / PLCs / SensorsControl airflow, temperature, humidity leelavati automation  HVAC Applications SectorUse Case IndustrialCooling for production, server rooms, CNC areas CommercialOffice climate control, malls, auditoriums HealthcareOperating rooms, labs with HEPA filtration ResidentialVillas, apartments with ductless splits HospitalityGuest room ACs, banquet halls, lobbies   Automation & Smart Control Modern HVAC systems are often integrated with BMS (Building Management System) or IoT-based smart controllers.   Thermostat AutomationScheduled temperature settings Zone ControlSeparate control for each room/zone VFD IntegrationEnergy savings by variable fan speed Remote MonitoringVia app or SCADA system CO₂ / VOC SensorsImprove indoor air quality Fault Alarms / Predictive MaintenanceReduce downtime, extend equipment life leelavati automation  Cooling Capacity1 TR – 500 TR (ton of refrigeration) Airflow Rate300 – 10,000 CFM (cubic feet per minute) Efficiency RatingCOP 2.5 – 4.5 / EER / ISEER Noise Level35 – 65 dB (residential vs industrial) Power Supply230V (residential) / 415V (industrial)       Split AC (ductless)1–2 TR Ducted Split System VRF/VRV Systems Central Chiller Plant50–500 TR AHU (Air Handling Units)1000–10,000 CFM BMS or PLC Automation Panel—   design complexity, and control system used.   Key Design Considerations Building load calculation (ASHRAE/ISHRAE standards)   HVAC zoning layout   Duct design and pressure drop   Fresh air intake and exhaust requirement   Air filtration grade (G4 to HEPA)   Energy efficiency targets (green building, IGBC/LEED)     ASHRAE 62.1 / 90.1Ventilation & energy efficiency ISHRAE GuidelinesIndian design standards NBC 2016 (India)Ventilation codes for buildings IEC 60335-2-40Safety of HVAC appliances ISO 16813 / 50001Energy efficiency and management   Benefits of a Modern HVAC System Energy-efficient climate control    Improved indoor air quality   Comfort with automated temperature & humidity   Smart building integration    Reduced maintenance with
