BuildingAHU

This module includes a class for central AHU

class teaser.logic.buildingobjects.buildingsystems.buildingahu.BuildingAHU(parent=None)

Bases: object

Building Class

This class represents a BuildingAHU.

!AixLib sepcific!

Parameters:

parent: Project()

The parent class of this object, the Building the AHU belongs to. Allows for better control of hierarchical structures. (default: None)

Attributes

heating (Boolean (default = True)) Heating Function of AHU
cooling (Boolean (default = True)) Cooling Function of AHU
dehumidification (Boolean (default = True)) Dehumidification Function of AHU (Cooling and Heating must be enabled)
humidification (Boolean (default = True)) Humidification Function of AHU (Cooling and Heating must be enabled)
heat_recovery (Boolean (default = True)) Is a HeatRecoverySystem physically integrated in the AHU? in AixLib: “HRS”
by_pass_dehumidification (float (default = 0.2)) By-pass factor of cooling coil during dehumidification. Necessary to calculate the real outgoing enthalpy flow of heat exchanger in dehumidification mode taking the surface enthalpy of the cooling coil into account. In AixLib called “BPF_DeHu”
efficiency_recovery (float (default = 0.8)) efficiency of HRS in the AHU modes when HRS is enabled. in AixLib: “efficiencyHRS_enabled”
efficiency_revocery_false (float (default = 0.2)) taking a little heat transfer into account although HRS is disabled (in case that a HRS is physically installed in the AHU) in AixLib: “efficiencyHRS_disabled”
sample_rate (int (default = 1800)) sample rate of state machines in AHU model. Default is set to half an hour as typical input is hourly
efficiency_fan_supply (float (default = 0.7)) Efficiency of supply fan
efficiency_fan_return: float (default = 0.7) Efficiency of return fan
pressure_drop_fan_supply: float (default 800) Pressure drop assigned to supply fan in Pascal
pressure_drop_fan_return: float (default 800) Pressure drop assigned to return fan in Pascal
profile_temperature ([float]) timeline of temperatures requirements for AHU simulation
profile_min_relative_humidity ([float]) timeline of relative humidity requirements for AHU simulation
profile_max_relative_humidity ([float]) timeline of relative humidity requirements for AHU simulation
profile_v_flow ([int]) timeline of desired relative v_flow of the AHU simulation (0..1)
