overview

+

This is a model for Facade Ventilation Unit (FVU), which can be used for heating, cooling and ventilation purposes.

+


Level of Development

+

+


Operation Modes of FVU:

+

The fresh air sucked in by the fan may flow through the heat recovery unit or through the bypass flap or through both of them. Depending on the operation mode, the fresh air cools down or heats up in the cooler or the heater to reach the desired supply temperature before it flows into the room. The air sucked out of the room may flow through the circulation air flap or heat recovery unit or both of them. The heater and the cooler are supported by the hot and cold water curcuis, respectively.

+


FVU Components:

+

Supply- and Exhaust fans:

+

The supply- and exhaust fans are modelled based on a table that gets an input signal in percent and gives a mass flow rate according to the data defined in the table. However, in order to achieve a high level of acoustic comfort, the power share input signal is limited to max. 50%.

+

Circulation Air flap:

+

In case of heating or cooling mode, it is checked if the mass flow rate through the supply fan is higher than the mass flow rate through the exhaust fan, and if so, circulation air operation gets activated. In this mode, the circulation air flap gets a signal from FVU-Controller, which means calculating a corresponding flap opening. The input signal Circ is defined as below:

+

+

Recuperator, Heat Recovery and Bypass flap:

+

In order to preheat or precool the fresh air before flowing through the heater/cooler a recuperator is located between the fresh and exhaust air. In case of heating or cooling mode and when the free heating or free cooling are not activated (RH_free and RC_free = false), fresh air flows completely through the bypass flap. However at any time a maximum value from FVU-Controller is selected as an input signal for heat recovery flap. According to this input Signal it will be calculated how much volume flow rate flows through the bypass flap at any time. The Recuperator is so modelled that the efficiency of recuperator based on manufacturer data is readed as a function of volume flow rate. By defining the maximum heat power exchanged between the fresh and exhaust air in counter current flow recuperators, the heat power can be calculated at any time. here the recuperator is shown schematic:

+

+

Heat Power of recuperator is calculated as below:

The model calculates the exergy content of a medium flow consisting of multiple substances. The reference environment is variable. The underlying equation is

+

\"dE/dt=dm/dt*(h-h_ref-T_ref*(s-s_ref))\"/

+

with \"dE/dt\"/: exergy flow rate, \"dm/dt\"/: mass flow rate, \"h\"/: specific enthalpy, \"T\"/: temperature, \"s\"/:specific entropy

+

The reference environment is modeled using a boundary with temperature, pressure and composition as input. The medium model is replaceable. The physical enthalpy and entropy are determined using the respective sensors from MSL. The sensor is ideal, i.e., it does not influence the fluid.

The model calculates the exergy content and its rate of change of a stratefied storage (i. e. with multiple layers) filled with a medium consisting of multiple substances. The reference environment is variable. The basic equation is

+

\"E=m*(h-h_ref-T_ref*(s-s_ref))\"/

+

with \"E\"/: exergy content, \"m\"/: mass, \"h\"/: specific enthalpy, \"T\"/: temperature, \"s\"/:specific entropy

+

The reference environment (subscript \"_ref\"/) is modeled using a boundary with temperature, pressure and composition as input. The medium model is replaceable. The physical enthalpy and entropy are determined using the respective sensors from MSL. The rate of change of the exergy content is calculated using the approximate derivative block from MSL.

This is the base definition is zone records used in AixLib.Building.LowOrder.ThermalZone. All necessary parameters are defined here. Most values should be overwritten for a specific building, some are default values that might be appropriate in most cases. However, fell free to overwrite them in your own records.

Remark: The design heating power Q_N of the building is the sum of net design power according to transmission and ventilation losses at a given outdoor temperature and an additional re-heating power for early morning heat up after night set-back. Net design power can be simulated with constant boundary conditions (e. g.: no internal or external gains, Touside=-12 degC, ACH=0.5). The additional re-heating power is computed by a factor [f_RH]=W/m2 and the heated zone floor area.

This model is the controller of the facade ventilation unit.

+

Level of Development

+

+


It makes use of six two-point controllers that determine

+

- Heating

+

- Cooling

+

- Ventilation

+

demand and indicate if

+

- Free cooling

+

- Heat recovery

+

- Cold recovery

+

is possible.

+

As these are decentralized controllers and as the fresh air temperature is measured inside the unit, we require an additional measurement mode. This mode is activated every two hours if there is no ventilation demand and the unit consequently circulates air. In order to measure the correct fresh air temperature, the circulation damper is closed for twenty minutes. Furthermore, the exhaust air fan is switched on and the fresh air damper is opened. This allows ambient air to flow inside the unit.

+

The temperature set point in cooling mode is increased by adding the value "deltaTemp" to the set point in heating mode.

Overview

+

This is a model for Facade Ventilation Unit (FVU), which can be used for heating, cooling and ventilation purposes. It is equipped with two speed-controlled fans, a recuperator and two air-water heat exchangers.

+


Level of Development

+

+


Operation Modes of FVU:

+

The portion of fresh air flowing through the recuperator is controlled by means of a bypass damper. The portion of extract air that is recirculated and mixed with the fresh air stream is controlled by means of a circulation damper. The mixed air stream is either heated or cooled in the air-water heat exchangers. The water flow in these heat exchangers is controlled by two-way-valves.

+

Actuators

+

All actuators receive normailized signals (0-1). The supply- and exhaust air fans are table-based. An input signal in % is transformed into a mass-flow set point for a flow-controlled mover. If the exhaust air fan is not in operation, the entire air flow should be recirculated. Thus, the circulation damper should be fully opened. In that case, the fresh air flap should be closed so that no fresh air can enter the unit. The exhaust air fan has a minimum mass flow rate of 1 m³/h to make the model more stable.

Remark: The design heating power Q_N of the building is the sum of net design power according to transmission and ventilation losses at a given outdoor temperature and an additional re-heating power for early morning heat up after night set-back. Net design power can be simulated with constant boundary conditions (e. g.: no internal or external gains, Touside=-12 degC, ACH=0.5). The additional re-heating power is computed by a factor [f_RH]=W/m2 and the heated zone floor area.

    The reference environment is modeled using a boundary with temperature, pressure and composition as input. The medium model is replaceable. The physical enthalpy and entropy are determined using the respective sensors from MSL. The sensor is ideal, i.e., it does not influence the fluid.

    Overview

    +

    Dynamic Pipe with pipe wall and insulation wall which allows discretisation of pipe wall and pipe insulation.This model considers heat loss through radiation and convection. It is useful when pipe is not embedded in wall.

    +

    Level of Development

    +

    +

    Concept

    +

    Developed by using the DynamicPipeEBCAggregated model from the EBC HVAC library. The model already includes heat-transfer by convection and by radiation. Instead of modeling these phenomena outside the pipe, an ambient temperature can be prescribed at the heat-port and the star of the pipe, so the loss to ambient will be calculated within the pipe model. The purpose is to clean up bigger models and to simplify modeling systems with pipes outside building-walls.

    +

    Differently from DPE_ambientLoss for each discretisation of the pipe, there is a connector to the corresponding element of the discretized pipe wall. Each element of the discretised pipe wall is connected to a corresponding element of the discretized insulation wall. The heat-ports and stars of all nodes are then collected to form two single ports, which can be connected to an ambient temperature.

    +

    It is possible to choose no insulation, if used for example for CCA ( concrete core activation).

    +

    overview

    -

    This is a model for Facade Ventilation Unit (FVU), which can be used for heating, cooling and ventilation purposes.

    -


    Level of Development

    -

    -


    Operation Modes of FVU:

    -

    The fresh air sucked in by the fan may flow through the heat recovery unit or through the bypass flap or through both of them. Depending on the operation mode, the fresh air cools down or heats up in the cooler or the heater to reach the desired supply temperature before it flows into the room. The air sucked out of the room may flow through the circulation air flap or heat recovery unit or both of them. The heater and the cooler are supported by the hot and cold water curcuis, respectively.

    -


    FVU Components:

    -

    Supply- and Exhaust fans:

    -

    The supply- and exhaust fans are modelled based on a table that gets an input signal in percent and gives a mass flow rate according to the data defined in the table. However, in order to achieve a high level of acoustic comfort, the power share input signal is limited to max. 50%.

    -

    Circulation Air flap:

    -

    In case of heating or cooling mode, it is checked if the mass flow rate through the supply fan is higher than the mass flow rate through the exhaust fan, and if so, circulation air operation gets activated. In this mode, the circulation air flap gets a signal from FVU-Controller, which means calculating a corresponding flap opening. The input signal Circ is defined as below:

    -

    -

    Recuperator, Heat Recovery and Bypass flap:

    -

    In order to preheat or precool the fresh air before flowing through the heater/cooler a recuperator is located between the fresh and exhaust air. In case of heating or cooling mode and when the free heating or free cooling are not activated (RH_free and RC_free = false), fresh air flows completely through the bypass flap. However at any time a maximum value from FVU-Controller is selected as an input signal for heat recovery flap. According to this input Signal it will be calculated how much volume flow rate flows through the bypass flap at any time. The Recuperator is so modelled that the efficiency of recuperator based on manufacturer data is readed as a function of volume flow rate. By defining the maximum heat power exchanged between the fresh and exhaust air in counter current flow recuperators, the heat power can be calculated at any time. here the recuperator is shown schematic:

    Heat Power of recuperator is calculated as below:

    The model calculates the exergy content of a medium flow consisting of multiple substances. The reference environment is variable. The underlying equation is

    -

    \"dE/dt=dm/dt*(h-h_ref-T_ref*(s-s_ref))\"/

    -

    with \"dE/dt\"/: exergy flow rate, \"dm/dt\"/: mass flow rate, \"h\"/: specific enthalpy, \"T\"/: temperature, \"s\"/:specific entropy

    -

    The reference environment is modeled using a boundary with temperature, pressure and composition as input. The medium model is replaceable. The physical enthalpy and entropy are determined using the respective sensors from MSL. The sensor is ideal, i.e., it does not influence the fluid.

The physical enthalpy and entropy are determined using the respective sensors from MSL. The rate of change of the exergy content is calculated using the approximate derivative block from MSL.

    Remark: The design heating power Q_N of the building is the sum of net design power according to transmission and ventilation losses at a given outdoor temperature and an additional re-heating power for early morning heat up after night set-back. Net design power can be simulated with constant boundary conditions (e. g.: no internal or external gains, Touside=-12 degC, ACH=0.5). The additional re-heating power is computed by a factor [f_RH]=W/m2 and the heated zone floor area.

    overview

    -

    This is a model for Facade Ventilation Unit (FVU), which can be used for heating, cooling and ventilation purposes.

    -


    Level of Development

    -

    -


    Operation Modes of FVU:

    -

    The fresh air sucked in by the fan may flow through the heat recovery unit or through the bypass flap or through both of them. Depending on the operation mode, the fresh air cools down or heats up in the cooler or the heater to reach the desired supply temperature before it flows into the room. The air sucked out of the room may flow through the circulation air flap or heat recovery unit or both of them. The heater and the cooler are supported by the hot and cold water curcuis, respectively.

    -


    FVU Components:

    -

    Supply- and Exhaust fans:

    -

    The supply- and exhaust fans are modelled based on a table that gets an input signal in percent and gives a mass flow rate according to the data defined in the table. However, in order to achieve a high level of acoustic comfort, the power share input signal is limited to max. 50%.

    -

    Circulation Air flap:

    -

    In case of heating or cooling mode, it is checked if the mass flow rate through the supply fan is higher than the mass flow rate through the exhaust fan, and if so, circulation air operation gets activated. In this mode, the circulation air flap gets a signal from FVU-Controller, which means calculating a corresponding flap opening. The input signal Circ is defined as below:

    -

    -

    Recuperator, Heat Recovery and Bypass flap:

    -

    In order to preheat or precool the fresh air before flowing through the heater/cooler a recuperator is located between the fresh and exhaust air. In case of heating or cooling mode and when the free heating or free cooling are not activated (RH_free and RC_free = false), fresh air flows completely through the bypass flap. However at any time a maximum value from FVU-Controller is selected as an input signal for heat recovery flap. According to this input Signal it will be calculated how much volume flow rate flows through the bypass flap at any time. The Recuperator is so modelled that the efficiency of recuperator based on manufacturer data is readed as a function of volume flow rate. By defining the maximum heat power exchanged between the fresh and exhaust air in counter current flow recuperators, the heat power can be calculated at any time. here the recuperator is shown schematic:

    -

    -

    Heat Power of recuperator is calculated as below:

    The model calculates the exergy content of a medium flow consisting of multiple substances. The reference environment is variable. The underlying equation is

    -

    \"dE/dt=dm/dt*(h-h_ref-T_ref*(s-s_ref))\"/

    -

    with \"dE/dt\"/: exergy flow rate, \"dm/dt\"/: mass flow rate, \"h\"/: specific enthalpy, \"T\"/: temperature, \"s\"/:specific entropy

    -

    The reference environment is modeled using a boundary with temperature, pressure and composition as input. The medium model is replaceable. The physical enthalpy and entropy are determined using the respective sensors from MSL. The sensor is ideal, i.e., it does not influence the fluid.

    The model calculates the exergy content and its rate of change of a stratefied storage (i. e. with multiple layers) filled with a medium consisting of multiple substances. The reference environment is variable. The basic equation is

    -

    \"E=m*(h-h_ref-T_ref*(s-s_ref))\"/

    -

    with \"E\"/: exergy content, \"m\"/: mass, \"h\"/: specific enthalpy, \"T\"/: temperature, \"s\"/:specific entropy

    -

    The reference environment (subscript \"_ref\"/) is modeled using a boundary with temperature, pressure and composition as input. The medium model is replaceable. The physical enthalpy and entropy are determined using the respective sensors from MSL. The rate of change of the exergy content is calculated using the approximate derivative block from MSL.
