Comfort and well-being in rooms and buildings are important prerequisites for people to
be satisfied
here in shopping centers
hotels
hospitals
offices
or factories.
Also building operators pursue the objective of ensuring the required comfort level with
a minimum energy usage.
The well-being of employees in a company has an impact on precision, efficiency, and productivity
and therefore the success of the company.
Siemens offers a unique range of products and systems for building automation and control.
From field devices
to automation stations
and building automation and control systems.
The range of products and systems insure the required comfort levels throughout the world
while delivering maximum energy efficiency.
Comprehensive know-how and decades of experience in building automation and control are included in this offering.
Intelligent functions, called applications, integrated in the automation stations insure
optimum room humidity and temperature control
making certain that individual comfort conditions are fulfilled.
The applications are tested and optimized in the unique heating, ventilation, and air
conditioning laboratory,
in short: HVAC laboratory,
designed and constructed by Siemens.
>> By giving considerations to all relevant influencing factors,
such as type of building construction and thermal insulation,
building size and furniture in the rooms, usage and weather conditions,
Siemens insures the highest level of quality in terms of comfort, control accuracy, and
energy efficiency.
The result: tested and proven applications.
All plant components required for heating, ventilation, and air conditioning, are installed
on a total laboratory area of more than 800 square meters.
Their interaction allows intensive tests to be made using real life conditions
for a test chamber to satisfy the requirements placed on products and systems by today's
modern building standards.
All types of building structures can be simulated
-- from light to heavy construction with concrete floors and ceilings including glass facades.
Dummies in the form of blue columns are used to simulate people coming and going.
Leading-edge industrial measuring technology is employed to check the measured values
captured by the various sensors and room climate control, based on airflow rates, temperatures,
humidity, and indoor air quality.
Using this global thermometer for example, consideration is given to the amount of heat
energy emitted by people, furniture, and walls
-- therefore improving the performance of the system and enhancing room comfort.
To provide the desired climatic conditions a complex system with a large number of components
operates in the background including:
different types of heating boilers, heat pumps, and domestic hot water storage tanks
up to 3 air conditioning systems for producing the required room climate and for simulating
the weather
chillers and a piping and air duct network many kilometers in length for the distribution
of heat and air
These tests made in the HVAC laboratory under real life conditions represent a decisive
element in the product development process.
>> Today, applications are entirely developed on the computer in a virtual world.
To ensure that a newly developed application works not only in a simulated environment,
it is taken to the real world step-by-step
whereby new tests are conducted at each step.
The following tests are made:
development and test of the application on the computer using a simulated plant
test for the real automation station and a simulated plant
and finally the test of the HVAC laboratory with a real controller and a real plant.
>> Only at this point is it possible to see if they new application really satisfies the
actual requirements and whether the required functionality in terms of control performance
and energy optimization are insured.
On completion of these extensive tests in the HVAC laboratory the products and applications
can be installed with good conscience in the customer plant.
Siemens attaches great importance to extensive application tests in the HVAC laboratory.
Only this high-tech laboratory, in which the interplay of energy production, energy distribution,
and room comfort control is tested, can ensure optimum control.
Or in other words: energy efficient control at a high performance level
Based on decades of experience in the field of building automation and control this high-tech
HVAC laboratory enables Siemens to ensure the highest levels of quality and control accuracy.
And to deliver perfectly matched and proven applications to our customers.
The benefits that these proven applications offer to users and building operators are clear:
enhanced comfort while ensuring great energy efficiency
well-being and satisfaction of guests, visitors, and patients
optimum working conditions for employees and therefore best preconditions for high precision,
efficiency and productivity
And all this worldwide.
