8 Hydraulic Integration for Heating and Cooling Operation
The generated cooling capacity is distributed using the heat
distribution system which is also to be configured for distributing
cold water.
Condensate can form due to the low flow temperatures,
especially in case of dynamic cooling. All pipework and exposed
manifold fittings must be fitted with steam-resistant insulation.
Vulnerable points in the cooling distribution system can also be
equipped with a dew point monitor available as a special
accessory. This will halt cooling operation in the event of
moisture formation.
Refer to the Project Planning and Installation Manual for Heat
Pumps for general information regarding the installation and
integration of heat pumps.
