SIMATIC for industrial HVAC

SIMATIC,

the trademark for efficient automation solutions in manu-

facturing and process control, is also the right choice as far

as solutions for industrial building automation systems areconcerned.

HVAC solutions based on SIMATIC provide the

following advantages:

Totally Integrated Automation

When implementing optimized automation solutions in

industrial applications, one of the most important tasks is

to implement all plant areas as well as all auxiliary systemsuniformly with one single technology.

HVAC (Heating, Ventilation & Air Conditioning) is one of the

most important auxiliary systems, decisive for production

as well as for a consistently high product quality.

Both the horizontal and vertical integration of the automation

solution into production and the auxiliary systems ensure

optimum availability, a high degree of effectiveness and the

economic efficiency of the entire plant.

Cost reduction

SIMATIC S7 is the leading industrial automation system in

the market. It covers almost all tasks in manufacturing and

process automation.

With HVAC solutions that are based on SIMATIC, the user

benefits from the uniformity of the industry standard. As

a result, you have the following advantages:

Use of one single automation system for processing/

production and auxiliary systems

Cost reduction thanks to the standardization of

components on the automation level

Industry-standard HVAC automation quality

Easy operator control and monitoring

Reduced number of interfaces

Simplification of maintenance and servicing

Integration

The integration of automation from production to building

technology increases efficiency, reliability and economic

efficiency of the entire plant. SIMATIC HVAC is an open, fast,precise and extremely reliable system specifically designed

for industrial requirements. Thus it offers a maximum of

integration and flexibility in addition to operating safety.

All from a single source integration of field devices

HVAC has many different proprietary field devices. Field

devices are, for example, valves, damper actuators, pumps

as well as special designs and versions of sensors and

actuators. Siemens Building Technology offers a wide

range of these products. Thanks to the cooperation of

the A&D and SBT Divisions, the customer now receivesall components required for an HVAC solution based on

SIMATIC from a single source.

SIMATIC Easy Select

Until now, HVAC requirements could only be met by using

larger SIMATIC S7 controllers.

New is the library

HVAC Lite Library

for small standalone applications in heating, ventilation

and air-conditioning systems for a particularly low-cost

implementation, since this library has been designed for

the cost-effective mini PLCs and compact controls of the

S7-300 and ET 200S CPU device family. This library

can therefore be used for the automation of hall ventilation

and ventilation systems, or even small air conditioning

systems without separate visualization and with no or

just a slight degree of networking.

The HVAC Lite Library is the main component of the new

SIMATIC HVAC Easy Select configuration solution for the

optimized processing of simple HVAC applications. Pres-

ently, six configuration solutions have been defined:

5/8

The configuration solutions show the optimum compo-

nent selection for the respective application, for the

controller and appropriate I/O as well as for a range of

applicable field devices from which the required actuators

and sensors have to be selected. To round it off, the

HVAC Lite Library is an add-on library to STEP 7 for HVAC

applications and enables the solution provider to develop

a corresponding system solution with minimum overhead.

The supplied variant of the library contains sample projects

for all seven Easy Select tasks, which then only need to be

configured according to the data contained in the project.

The HVAC Lite Library has very little memory requirements,

so that small S7 controllers can be used for the respective

solutions. Thus, the user is now also able to serve the

industrial HVAC sector that demands such small, cost-

effective standalone HVAC applications. The number of

SIMATIC HVAC Easy Select variants is principally not fixed.

Depending on the requirements on correspondingly pre-

configured solutions, further configuration solutions can

be created.

SIMATIC Easy Select:Application examplesThese four application examples describe how you can use the

SIMATIC HVAC Easy Select packages for your heating, air condi-

tioning and ventilation tasks.

SIMATIC HVAC Easy Select packages are configuration solutions that

show how you can configure a specific HVAC application quickly

and easily. They consist of different hardware components from

SIMATIC controllers to I/O units right up to a selection of correspond-

ing field devices.

The heart of the SIMATIC HVAC Easy Select package is the add-on

HVAC Lite Library for STEP 7, which you can use to configure the

required application quickly and conveniently. And to make it even

easier for you, we have included a sample application that matches

the particular task specification to be covered by the package.

All you have to do is set the relevant parameters.

Mixed air ventilation system,heating, cascade control

Application/savings

You want to configure a heating system as a

mixed air ventilation system with cascade con-

trol? Thats no problem if you are using the right

SIMATIC HVAC Easy Select package!

The advantage of the room supply air or extract

air cascade control is the considerably enhanced

control performance compared to a regular room

temperature control. Thus you can achieve an

enhancement of the control quality by a factor

of 5 to 8 and accelerate the control compared

to when using a room temperature sensor.

Furthermore, the use of recirculated air saves

heating energy.

The cascade control makes it possible to limit

the maximum supply air temperature, which

cannot be done with a regular room temperature

control.

The HVAC Lite Library also includes STEP 7 sample

applications for configuring the described HVAC

task. The SIMATIC HVAC Easy Select configuration

solution thus helps you to reach your goal faster.

Outside air ventilation system,heating/cooling, cascade control

Application/savings

This last HVAC sample application, which is cov-

ered by the SIMATIC HVAC Easy Select package 4,

has all the advantages of the previously described

applications plus the possibility of cooling with

extract air.

Limitation of the maximum and minimum

supply air temperature is possible here as well,

as described in the previous examples. By

raising the room temperature setpoint in the

summer time in accordance with DIN 1946,

cooling energy is saved.

The cooling coil is hydraulically driven with con-

stant cold water flow since no precipitation of

humidity is required. This enables considerable

energy savings compared to volume-controlled

cooling coil operation.

As in the three previous HVAC tasks, a sample

configuration is included in the scope of supply

of the HVAC Lite Library for the SIMATIC HVAC

Easy Select package 4. The sample configuration

only needs to be adapted to the specific

requirements of the individual application.

Application/savings

The application of the outside air ventilation

system with heating option described by SIMATIC

HVAC Easy Select 3 has the savings benefits of

the two Easy Select configuration solutions de-

scribed above based on the outside air ventilation

principle.

Outside air ventilation system,

heating, cascade control

Application/savings

In addition to the functionality described with

the first SIMATIC HVAC Easy Select package, the

minimum and maximum supply air temperature

can be limited. A regular room temperature

control system cannot do this.

The HVAC task implemented in the second

SIMATIC HVAC Easy Select package also includes

the use of recirculated air. If adhering to the

minimum outside air rate, a great amount of

energy can be saved. In particular, when cooling

with high outside temperatures, savings can be

very significant if you switch over to a minimum

proportion of outside air. An additional energy

savings potential is the possibility to increase the

room temperature setpoint in the summer time

according to DIN 1946.

Considerable energy savings can be achieved

with an application described in the SIMATIC

HVAC Easy Select package by measuring the

extract air temperature. A relevant sample

application is supplied with the HVAC Lite Library.
