Easier design of
technical insulations
Proper design and installation of an insulation layer is critical
to the safety and energy efficiency of HVAC systems and
process industry pipelines.
As in the case of building insulations, it is crucial to provide
certain pipes, ducts and equipment with the best-suited
technical insulation solutions, especially when considering
numerous variables that need to be taken into account. In
order to make it easier for clients to design and construct
HVAC and industry pipework, Paroc has introduced Paroc
Calculus.
When calculating optimal insulation for pipes, ducts, flat
surfaces and process industry tanks, designers need to
consider factors such as potential and maximal heat loss,
content and environment temperature, the medium’s flow
velocity, and pipe material and dimensions – all in accordance
with EN ISO 12241 (thermal insulation for building equipment
and industrial installations). Based on this standard, Paroc
Calculus offers thorough calculations for various types
of HVAC and process industry objects: pipes, ducts, flat
surfaces and circular and rectangular tanks.
The accessible interface allows designers to implement a
large number of project parameters, ranging from the object’s
physical dimensions (length, thickness, inner diameter),
content (medium type, initial and final temperature, flow
rate), environment (indoor/outdoor, ambient temperature and
air velocity, relative humidity), to the energy characteristics
(energy source, annual operating time, price of energy). For
products that require support for external cladding, influence
of the heat loss can be specified (typically values between 15
and 25 per cent).
All calculations are based on equations described in standard
EN ISO 12241. Operating on the given data, Paroc Calculus
helps to choose an optimal solution for different types of
constructions – the program provides specific product
suggestions and economically viable insulation thickness.
By adding additional insulation layers, users can follow
real-time changes in performance results, eg heat loss
and uninsulated heat loss volume, surface temperature,
dew point, CO2 emission and average annual savings. In
cases where product properties are exceeded, a warning is
displayed.
The program’s product database is expandable: builders and
designers can add other insulation products for inclusion
in future calculations. In order to do so, the program will
ask users to fill in thermal conductivity at four different
temperatures as well as the emissivity of the surface. The
program then calculates the Lambda – temperature curve.
Paroc Calculus is available in a web-based version, and a
downloadable version with increased functionality.
