Insulation
Insulation of pipes utilized for transmitting thermal energy conveying liquids is in general always recommended, because
the insulation reduces losses of valuable heat energy or avoids heating of the medium, which is utilized for cooling. Thus,
insulation optimizes the supply of thermal energy with thermal energy conveying liquids. To further optimize the supply,
insulation of flow and temperature sensors, which are both in direct contact with the thermal energy conveying liquid,
must also be addressed. As the calculator of a heat/cooling meter is not in direct contact with the thermal energy
conveying liquid, insulation of the calculator as such is not applicable. However, due to the possibility of mounting the
calculator directly on the flow sensor, installation recommendations for the calculator must be considered depending on
the temperature of the medium and the environment.
Insulation has the effect, that all parts under the insulation might reach temperatures up to the temperature of the
thermal energy conveying liquid as thermal balance to the environment is prohibited. This might be critical to some
components, in particular to sensitive electronics. Predominantly in cooling installations, humidity from the warm
environment will condense on comparatively colder pipes. This is why they are often permanently wet. Insulation
therefore requires temperature stability of the insulated parts within the approved range of the medium temperature as
well as waterproof encapsulation of sensitive electronic components in cooling installations in warm and humid
environments. Finally, note that local rules concerning insulation of pipes might apply.
