WOLF run around coil systems
6. THERM-CONNECT basic
06.01 General description
The high efficiency run around coil system consists of two heat exchangers with a high counterflow ratio and a
series connection of the individual heat transfer stages.
The heat is transferred via an intermediate medium consisting of a water-glycol mixture between the exhaust air coil
and the outdoor air coils.
The brine mass flow is controlled by the three-way control ball valve depending on the power demand of the BMS.
In addition, frost protection can be controlled via this using a temperature sensor provided by the customer. This
allows the brine mass flow to be routed past the supply air coil in order to prevent ice formation on the coil. The
pump is controlled digitally by switching the operating voltage through an on-site contactor.
