WOLF run around coil systems
8. THERM-CONNECT magna
08.01 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 coil.
The brine mass flow is controlled by the integrated control system depending on the power requirement of the BMS,
the air volume flow in supply air and exhaust air and the temperature conditions in the system.
The power and frost protection control is also carried out via the three-way mixing valve with high control accuracy.
This allows the brine mass flow to bypass the supply air register to prevent ice formation on the register.
Optional extensions can be used to integrate an adiabatic exhaust air humidifier, the feeding of external additional
energy into the run around coil circuit, an accurate capacity determination with monthly data backup, a reheater for
dehumidification cold recovery or a redundant double pump for fail-safe operation.
Since the pumps are designed separately for each system, the flow rate must be adapted to the respective system.
This is done during commissioning of the system by a trained technician from WOLF Geisenfeld.
