HVAC Panel Heating, Ventilation, and Air Conditioning Control Panel is a specialized electrical enclosure that acts as the "central command" for a building's climate control system. It houses the components necessary to regulate temperature, humidity, air pressure, and air quality within a facility.

Technical Specifications

Core Components

§  DDC Controller: 
The "logic" unit (Direct Digital Control) that executes the programmed HVAC sequences.

§  VFDs / Starters: 
Power hardware that physically drives the fans and pumps.

§  Transformer: 
Steps down mains voltage to 24V AC/DC, the standard safety voltage for HVAC controls and actuators.

§  Relays & Contactors: 
Switch heavy electrical loads (like electric heaters) on and off.

§  Interface: 
HMIs or pilot lights for local status monitoring and manual overrides.

Primary Functions

§  Climate Regulation: 
Processes data from thermostats and sensors to adjust heating/cooling stages and modulating valves.

§  Variable Speed Control: 
Utilizes Variable Frequency Drives (VFDs) to adjust motor speeds, reducing energy consumption when full airflow is not needed.

§  Air Quality Management: 
Controls dampers to manage the mix of fresh outdoor air and recirculated air based on CO2 and pollutant sensors.

§  System Protection: 
Monitors for faults like motor overloads, belt breakages (via pressure switches), and frozen coils.

§  BMS Integration: 
Acts as a data gateway, communicating with a Building Management System (BMS) via protocols like BAC net or Modbus for centralized facility oversight.

Standard Tests
