Trend viewer

Recording of historic and current data such as temperature, drive positions, frequency converter-operational status etc., for easy analysis of online and offline time for optimizing the system. All actions

made by users, alarm messages, as also failures are also recorded and can where required, bedisplayed on an overview window for further analysis purposes.

Access rights

Access rights are issues to regulate the accesses of user groups.

The access rights for the user groups comprise among others the right to start or end a program. Theaccess to the graphical representations can be issued on an individual basis. The responsibility for theplant can thus be shared out among several users. Access to the system is by means of a password.

DDC substations

The DDC substations consist of the process device and the Input and output modules.

The Process device monitors the technical installations in the building plant and is integrated in the

appropriate BMS switching cabinet. The Input and output modules are linked to the process device byprocess bus and form the interface to the peripheral devices. The separate modules are pluggableand can be taken out or replaced for service purposes.

Process device

The process device can operate autonomously as a standalone, or also peer-to-peer with otherdevices that have equal rights or also as a master device (e.g. for floor level networks). The separateprocess devices are linked to the building management system (BMS) via a bus cable.

The unit is fitted with an integrated display. The current values and data points of the relevantcomponents can be either read or set at the site.

The basic device functions include:

carrying out of the unit specific processes in the program inserts Data traffic between input and output modules via the process bus Self monitoring of the connected devices controlling information available on display

System security

The following functions will be maintained by a UPS system (uninterrupted power supply) for at least60 days:

date and time microprocessor monitoring (Watchdog) user programs, configuration and process data

The service life of the battery is to be at least 4 years. The battery status will be displayed and

monitored by the process device.

The system carries out a controlled abort function on under voltage or power cuts (reset). The processbus and all communication lines are then passive, i.e. their transmission functions are switched off. Assoon as mains operational current is available again a defined re-start begins to ensure that the plantcan operate again on a functionally correct basis.

All connected input and output modules are passive on a process device failure.

I / O Modules


16/44



23.05.2011 Page 16 of 44

The I / O module system is the link between the process device and a plant with all its elements.I / O modules are changed by the signals passing through the process bus to the form required for thereceiving devices or elements and their functions.

The I / O modules are pluggable and can be newly loaded, removed or plugged without the need foradditional terminal connections or software.

The basic functions of the I / O modules are:

Reporting, measuring, counting, switching and setting. The switching, reporting and setting modules have an integrated status display.

Room temperature control

2.3.3. DESCRIPTION OF BASIC FUNCTIONS

General functions

Control in case of fire

In case of fire the system of fire alarm shuts down all the ventilation systems that arent used for fireextinguishing and smoke exhaust. BMS building control systems receives relevant no-voltage contactsfrom the fire alarm system to turn the fans on and off in accordance with the fire protection system.Fire protection screens are controlled by proximity switches. Closed signal is displayed individuallyfor each screen in graphical form on control station of BMS system.

Smoke exhaust

BMS System will monitor the ventilators and domed rooflights.

Shops and Mall

The smoke-exhaust fans are switched on and off via the fire alarm system, while safeguards andsupply must be linked into the emergency network and must be fire-resistant. The smoke in the mall isdischarged via openable domed rooflights.

The fire-prevention (fire-resistant) smoke flaps are to be actuated in accordance with the fire-prevention plan via the fire-alarm centre.

Stairwells, corridors or airlocks

Staircases, corridors or airlocks are kept free of smoke via their own pressure ventilation fans whichare activated only in the event of fire. In the event of fire, the corresponding fans will be called upindividually from the fire alarm system in accordance with the relevant fire safety plan via voltage-freecontact. The switching is done by the respective ICA (instrumentation, control and automation)cabinet. The smoke is vented through openable skylights by a smoke extraction fan.

Garage

Smoke in stairwells, corridors, or airlocks is extracted by forced draft via ventilators. The smoke is

vented by a smoke extraction fan.

The garage is divided into eight CO-extraction zones and into as many fire-smoke extraction zones.Both CO2 and smoke are extracted by means of the Jet System and by fire-gas exhaust fans. In bothcases, air is replenished naturally via fire-smoke dampers. Only that zone that has either an excessive

CO-concentration or where there is a fire alarm is ventilated and replenished. To vent CO thededicated fan is switched on, thus reducing the through-flow of air.

Protective functions

Protection against freeze over the air

Freezing relay protects the heating register of water heating from freezing.

Freezing relay sends the freezing alert signal to the controller when the temperature on the heating

register is lowered beyond the threshold value of freezing relay.

DDC regulation block then performs the following operations in the system:

EMERGENCY ACTIVATION opening of heating register valve and activation of heatingregister pump

EMERGENCY SHUTDOWN of forced-air and exhaust ventilation Closing of screens of outside air/out coming air with engine drive. Emergency shutdown of the system

Freezing alert is displayed in the BMS system and in the instrumentation and control system cabinet(BMS) using LED.


20/44



23.05.2011 Page 20 of 44

The function of protection against the freeze is active even after the facility shutdown.

Protection from the freeze over the water

Theres the immersion sensor built into recirculating circuit of heating register that measures thetemperature of working environment. If the temperature is lowered below set minimal value, forexample, 15C the heating register valve is opened in the relevant way by the DDC control block and

stays in such position before the minimal value is reached.Control functions

Filter control:

Differential pressure relay controls the degree of filter clogging. The more clogged the filter is, thestronger is the air resistance when passing through the air filter. If the air resistance in the filtersurpasses maximal allowed value, the differential pressure relay activates service alert signal Thefilter is clogged.

Filter clogging is displayed in the BMS system and in the instrumentation and control systemcabinet (BMS) using LED.

Pumps monitoring

The absence of working feedback signal or the engine failure signal initiates the emergency shutdownof the facility.

However, it happens only during low outside air temperature, when it is impossible to provide facilitywith the necessary amount of heat without heat recuperator. When the outside temperatures arehigher, only the signal of pump failure is displayed.

Engine protection failure signal is displayed in the BMS system and in the instrumentation and controlsystem cabinet using LED.

Fans monitoring:

The absence of working feedback signal through differential pressure relay or the engine failure signalinitiates the emergency shutdown of the facility.

Engine protection failure signal is displayed in the BMS system and in the instrumentation and controlsystem cabinet using LED.

For fans with V-belt drives, all-pole service switches are provided directly with the drives.

Control Functions

Program of time-based control

The aim of program of time-based control is to regulate the performance of the systems of heating,ventilation and air conditioning in accordance with the periods of use of the building and its premises,as well as the other needs with time based regulation both during the day and the whole year.

Time-based switching functions, included in time-based control program, provide:

Time-dependent activation and deactivation of heating system, ventilation and air conditioningor alteration of its stages, Increase or decrease of set values of heating system, ventilation and air conditioning and

correspondingly the setting of daily pro archives of temperature and humidity.

Restoration of mains supply

The system of restoration of the power supply after mains supply shutdown guarantees organizedstaged and load dependent activation of electric load of maintenance engineering devices after mainssupply shutdown.

Intensive night ventilation


21/44



23.05.2011 Page 21 of 44

In summer intensive night ventilation allows the economy of cooling energy, for this purpose in nighttime the premises are cooled by cold outside air before the next day.

Terms of intensive night ventilation activation:

System stage Intense night ventilation is activated if the following conditions are performedsimultaneously:

intensive night ventilation is activated by time-based control program; outside temperature surpasses set threshold value; inside temperature surpasses set threshold value; the temperature difference between outside and inside temperatures surpasses set

temperature differences.

Intensive night ventilation turns off:

by time-based control program, if one of abovementioned conditions is not fulfilled but no earlier than after set minimal

operating time.

Peak load program

The goal of peak load program is to regulate the energy consumption in such a way that maximal level

of energy consumption during measurement period that usually equates 15 minutes does not surpassfixed threshold value. To do that program connects and disconnects relevant number of loads. Theaim of the program is to prevent the appearance of current peaks and to use received electric energyin rational way. The energy received above threshold norm shall be paid for at higher rate inaccordance with local regulations on energy consumption.

That program regulates not only maximal power consumption but energy consumption in general(including heat). That allows for energy saving as power is supplied not voluntary but according to theplan and with set limits.

Fire dampers with or without electric drive

Fire dampers are closed during the fire using thermal trigger. In normal situation the dampers arealways opened.

The closing of fire dampers indicates that theres fire in the building. Signal of closed damper isprocessed in accordance with fire protection scheme.

Ventilating dampers with spring-based retraction

During de-energization the dampers are closed by themselves using spring-based retractionmechanism. Ventilation system works with supply and exhaust dampers that regulate the air volume orstop the air supply. If the ventilation system is active, the dampers are opened. They close during thesystem shutdown. The position of the dampers is regulated using the switching commands.

Additional switching contacts are used to ensure that the fans are turned on only when the dampersare partially or fully opened. Release time-dependent activation scheme.

Retraction spring

During de-energization the return spring puts the dampers in the emergency position.

Heating register (Double pump)

For the heating of outside or mixed air the air heater with pump-based water heating is provided.

The heater is integrated in the system of sequential regulation of the temperature of the room orincoming air, and the resulting output signal of controller acts as the executive command on therelevant heater valve.

A recirculating pump is integrated in the control circuit of air heater with pump-based water heating.

Recirculating pump is activated when necessary i.e. depending on the state of servo valve output (Y

With increasing demand for heat, the supply air temperature regulation operates in the followingmanner and sequence on the existing heat exchanger:

Increase the power of heat recuperators, * Increase the power of the pre air heater,** Increase the power of the post air heater,*/** Close the constant dampers up to 20 % circulating position.**

Cooling (Summer):

With increasing demand for cooling, the supply air temperature regulation operates in the followingmanner and sequence on the existing heat exchanger:

Increase the power of heat recuperators, * increase the power of air coolers

*: if possible/available

**: among themselves synchronized process (matrix)

Room temperature or exhaust air temperature regulation (shops> 1000 m; Mall; systems 2nd floor):

Heating (Winter):

When thermal load increases, the system of out coming air temperature regulation affects the existingheat exchanging machinery in the following way and order:

the dampers of permanent action closed in minimal position according air quality sensor(always)

Increase the power of heat recuperators, * power of air heaters is increased, ** power of secondary air heaters is increased,*/** Increase the performance of the FU,** the dampers of permanent action are closed in air recirculation position (super limitation),**

Cooling (Summer):

At the increase of cooling load the system of out coming air temperature regulation affects the existing

heat exchanging machinery in the following way and order: open the dampers of permanent action according air quality sensor (always) Increase the power of heat recuperators, * increase the power of air coolers

Cooling (Winter):

With increasing demand for cooling, the discharge air temperature regulation operates in the followingmanner and sequence on the existing heat exchanger:

Min. supply air temperature Open constant dampers according air quality sensor (always), (FU to min) Dampers opened

*: if possible/available

**: among themselves synchronized process (matrix)

Limitation of supply air temperature:

Incoming air temperature is limited to its minimal and maximal value. When theres the significantamount of outside heat in the premise, it prevents the temperature of incoming air from being loweredtoo much. Without this limitation low temperature of incoming air would have caused drafts.

Summer compensation (in cooling mode)

During the temperature regulation the set value is controlled depending on the outside temperature.During the change of outside temperature in the range between 22C and 32C, for example, set


24/44



23.05.2011 Page 24 of 44

value of room temperature gradually increases from 22C to 26C. It allows to avoid too largetemperature gradients between outside and inside temperatures and thus allows for more comfortmode. Besides, that measure allows to save the energy spent for cooling.

Heating

General information

The unblocking of the system for heating systems is activated depending on demand (e.g. via outsidetemperature, outside temperature curve, opening of heating valves, etc.), by seasonal switchingprogrammes or, if run, by optimisation programmes. An individual switching programme is definableand configurable for each system.

Energy is supplied via three gas boilers, all equipped with a dual burner (oil, gas) feature, whichprovides for limited emergency operation in the event that gas supply is interrupted. The boilers areengaged, based on performance, by the temperature level in the hydraulic separator.

In consumer closed-loop controls the temperature is managed via the associated control valve, where,as shown in the schemata, there is a slide of the set-point as a function of outside temperature.

For floor heating a maximum limit is provided for.

DDC functions such as weather-driven flow temperature control, room correction, standby,optimisation, pump protection and limiting, etc., serve as the basis for system programming.

The FM area (1st basement) will be regulated by a reference room thermostat (activation of thethermoelectric actuators).

Cooling

General information

Cold production is performed by chillers and cooling towers.

The higher-level release of the cooling systems is actuated based on demand (e.g. outdoortemperature or outdoor temperature curve) or by a seasonal scheduling programme. The release ofthe chillers is a function of storage temperature. If one chiller fails, the second network will be supplied

by the other remaining chiller.Increasing the chilled water temperature as a function of outside temperature (e.g.> 35C)

Inlet temperature regulation in the condenser circuit to the chillers.

Chiller regulation including filling, draining and frost protection

DDC functions such as flow temperature control, set-point slide, low limit, maximum limit, pumpprotection, etc. serve as the basis for system programming.
