The MCAE/FC free-cooling units are particularly suitable where chilled water all year long is required, so also by low ambient air temperature. The free-cooling system utilises the low outside temperature for chilling water in the coil starting from 15 °C ambient air temperature.
The units series MCAEY/FC are designed to cool down water/ glycol uid.
This units are equipped, further to the chiller components such as compressors, condensers, evaporator, thermostatic valves, with a water free-cooling coil. The control system consists of a modulating three- way valve and of a certain number of probes allowing the water coil functioning and therefore the “free-cooling” operation. In the standard chiller the return water/glycol uid is cooled down through the shell and tube evaporator. In the MCAEY/FC units working in free-cooling mode, the water/glycol uid runs through the free-cooling coil which is cooled by means of the external air, thus reducing the load on the compressors or even completely substituting them. The control system consists of a microprocessor, an inlet water temperature probe, an external air temperature probe, a working probe and a nofreezing probe.
