-There are two fans (i.e., one supply fan, and one return fan) in the AHU system. Only a cooling coil is installed in the AHU.
-![](\"modelica://MultiZoneOfficeComplexAir/../../doc/images/AHUControl.png\"/)
-Supply fan speed is controlled by a PI controller to maintain duct static pressure (DSP) at setpoint when the fan is proven ON.
-Cooling coil valve position is controlled by a PI controller to maintain the AHU supply air temperature at setpoint.
-In the mixing box of the AHU, an economizer is implemented to use the outdoor air to meet the cooling load when outdoor conditions are favorable.
-Outdoor air damper position is controlled by a PI controller to maintain the mixed air temperature at setpoint. It takes the mixed and outdoor air temperature measurements, as well as the mixed air temperature setpoints as inputs. It takes the outdoor air damper position as the output. The return air damper are interlocked with the outdoor air damper while exhausted air damper share the same opening position with the outdoor air damper. On top of that, an economizer control based on the fixed dry-bulb outdoor air temperature-based is adopted. The economizer higher temperature limit is set as 21 degC according to ASHRAE 90.1-2019 for Climate Zone 5A.

-A hot water reheat coil is installed in each VAV terminal. The components and control systems of the VAV is shown in the figure below:
-![](\"modelica://MultiZoneOfficeComplexAir/../../doc/images/VAVControl.png\"/)
-The controller for terminal VAV box is based on the "single maximum VAV reheat control logic".
-
-- When the Zone State is cooling, the cooling-loop output shall be mapped to the active airflow setpoint from the cooling minimum endpoint to the cooling maximum endpoint. Heating coil is disabled. When the Zone State is deadband, the active airflow setpoint shall be the minimum endpoint. Heating coil is disabled.
-- When the Zone State is heating, the active airflow setpoint shall be the minimum endpoint. The reheat valve position shall be mapped to the supply air temperature setpoint from the heating minimum endpoint to the heating maximum endpoint.
-
-VAV damper position is controlled by a PI controller to maintain the air flow rate at setpoint. Heating coil valve position is controlled by a PI controller to maintain the supply air temperature at setpoint.
-See the model

-
-This is a model of a boiler whose efficiency is described
-by a polynomial.
-The heat input into the medium is
-
- Q̇ = y Q̇0 η ⁄ η0
-
-
-where
-y ∈ [0, 1] is the control signal,
-Q̇0 is the nominal power,
-η is the efficiency at the current operating point, and
-η0 is the efficiency at y=1 and
-nominal temperature T=T0 as specified by the parameter
-T_nominal.
-
-
-The parameter effCur determines what polynomial is used
-to compute the efficiency, which is defined as
-
-
- η = Q̇ ⁄ Q̇f,
-
-
-where
-Q̇ is the heat transferred to the working fluid (typically water or air), and
-Q̇f is the heat of combustion released by the fuel.
-
-
-The following polynomials can be selected to compute the efficiency:
-
-
-
-Parameter effCur |
-Efficiency curve |
-
-
-| Buildings.Fluid.Types.EfficiencyCurves.Constant |
-η = a1 |
-
-
-| Buildings.Fluid.Types.EfficiencyCurves.Polynomial |
-η = a1 + a2 y + a3 y2 + ... |
-
-
-| Buildings.Fluid.Types.EfficiencyCurves.QuadraticLinear |
-η = a1 + a2 y
- + a3 y2
- + (a4 + a5 y
- + a6 y2) T
- |
-
-
-
-
-where T is the boiler outlet temperature in Kelvin.
-For effCur = Buildings.Fluid.Types.EfficiencyCurves.Polynomial,
-an arbitrary number of polynomial coefficients can be specified.
-
-
-The parameter Q_flow_nominal is the power transferred to the fluid
-for y=1 and, if the efficiency depends on temperature,
-for T=T0.
-
-
-The fuel mass flow rate and volume flow rate are computed as
-
- ṁf = Q̇f ⁄ hf
-
- and
-
- V̇f = ṁf ⁄ ρf,
-
-
-where the fuel heating value
-hf and the fuel mass density
-ρf are obtained from the
-parameter fue.
-Note that if η is the efficiency relative to the lower heating value,
-then the fuel properties also need to be used for the lower heating value.
-
-
-
-Optionally, the port heatPort can be connected to a heat port
-outside of this model to impose a boundary condition in order to
-model heat losses to the ambient. When using this heatPort,
-make sure that the efficiency curve effCur
-does not already account for this heat loss.
-
-
-
-On the Assumptions tag, the model can be parameterized to compute a transient
-or steady-state response.
-The transient response of the boiler is computed using a first
-order differential equation to compute the boiler's water and metal temperature,
-which are lumped into one state. The boiler outlet temperature is equal to this water temperature.

-Model of an electric chiller, based on the DOE-2.1 chiller model and
-the EnergyPlus chiller model Chiller:Electric:EIR.
-
- This model uses three functions to predict capacity and power consumption:
-
-
--
-A biquadratic function is used to predict cooling capacity as a function of
-condenser entering and evaporator leaving fluid temperature.
-
--
-A quadratic functions is used to predict power input to cooling capacity ratio with respect to the part load ratio.
-
--
-A biquadratic functions is used to predict power input to cooling capacity ratio as a function of
-condenser entering and evaporator leaving fluid temperature.
-
-
-
-These curves are stored in the data record per and are available from
-
-Buildings.Fluid.Chillers.Data.ElectricEIR.
-Additional performance curves can be developed using
-two available techniques (Hydeman and Gillespie, 2002). The first technique is called the
-Least-squares Linear Regression method and is used when sufficient performance data exist
-to employ standard least-square linear regression techniques. The second technique is called
-Reference Curve Method and is used when insufficient performance data exist to apply linear
-regression techniques. A detailed description of both techniques can be found in
-Hydeman and Gillespie (2002).
-
-
-The model takes as an input the set point for the leaving chilled water temperature,
-which is met if the chiller has sufficient capacity.
-Thus, the model has a built-in, ideal temperature control.
-The model has three tests on the part load ratio and the cycling ratio:
-
-
--
-The test
- PLR1 =min(QEva_flow_set/QEva_flow_ava, per.PLRMax);
-
-ensures that the chiller capacity does not exceed the chiller capacity specified
-by the parameter per.PLRMax.
-
--
-The test
- CR = min(PLR1/per.PRLMin, 1.0);
-
-computes a cycling ratio. This ratio expresses the fraction of time
-that a chiller would run if it were to cycle because its load is smaller than the
-minimal load at which it can operate.
-Note that this model continuously operates even if the part load ratio is below the minimum part load ratio.
-Its leaving evaporator and condenser temperature can therefore be considered as an
-average temperature between the modes where the compressor is off and on.
-
--
-The test
- PLR2 = max(per.PLRMinUnl, PLR1);
-
-computes the part load ratio of the compressor.
-The assumption is that for a part load ratio below per.PLRMinUnl,
-the chiller uses hot gas bypass to reduce the capacity, while the compressor
-power draw does not change.
-
-
-
-The electric power only contains the power for the compressor, but not any power for pumps or fans.
-
-
-The model can be parametrized to compute a transient
-or steady-state response.
-The transient response of the boiler is computed using a first
-order differential equation for the evaporator and condenser fluid volumes.
-The chiller outlet temperatures are equal to the temperatures of these lumped volumes.

-March 12, 2015, by Michael Wetter:
-Refactored model to make it once continuously differentiable.
-This is for issue 373.

-
-Jan. 10, 2011, by Michael Wetter:
-Added input signal to switch chiller off, and changed base class to use a dynamic model.
-The change of the base class was required to improve the robustness of the model when the control
-is switched on again.

-Sep. 8, 2010, by Michael Wetter:
-Revised model and included it in the Buildings library.
