HVAC Systems

Purpose: Models the heating, ventilation, and air conditioning systems of the building, including air handlers, boilers, and variable air volume (VAV) boxes.

Key Classes and Components

• AirHandler:

  • Controls the air flow and temperature in the building.

  • Attributes:

    • recirculation: Percentage of fresh air in the recirculation.
    • heating_air_temp_setpoint: Setpoint for heating air temperature.
    • cooling_air_temp_setpoint: Setpoint for cooling air temperature.
    • fan_differential_pressure: Pressure difference across the fan.
    • fan_efficiency: Efficiency of the fan.
    • max_air_flow_rate: Maximum air flow rate.
    • sim_weather_controller: Weather controller for ambient conditions.

• Boiler:

  • Provides heating by controlling water temperature.

  • Attributes:

    • reheat_water_setpoint: Setpoint for reheat water temperature.
    • water_pump_differential_head: Pressure difference across the water pump.
    • water_pump_efficiency: Efficiency of the water pump.
    • heating_rate: Rate at which the boiler can increase temperature.
    • cooling_rate: Rate at which the boiler can decrease temperature.

• FloorPlanBasedHvac:

  • Integrates the HVAC components into the building simulation.

  • Attributes:

    • air_handler: Instance of AirHandler.
    • boiler: Instance of Boiler.
    • schedule: Setpoint schedule for HVAC operation.
    • vav_max_air_flow_rate: Maximum air flow rate for VAV boxes.
    • vav_reheat_max_water_flow_rate: Maximum water flow rate for reheating.
