The WindMaker OCTAGON GGWC heating-cooling module combines mechanical ventilation with a ground-glycol heat exchanger (GGWC) to ensure air pre-cooling or pre-heating.
The module makes it possible to connect ground-glycol heat exchanger GGWC with a ventilation system. Depending on a season, the OCTAGON GGWC module, installed on a ventilation duct connecting air intakes with a recuperator, pre-cools (summer) or heats (winter) fresh air which is later distributed to rooms (through a heat-exchanger of a double bypass system in WindMaker recuperators).
The OCTAGON module is controlled by automation systems of these recuperators.
OCTAGON GGWC is a thermally insulated module of exclusive appearance including an in-built heat exchanger, automatic bypass damper (230 V actuator), complete hydraulic system with a circulation pump, outlet stub pipe plus angular rotameter and thermometer to control the flow and temperature of heat transfer fluids as well as ready-made electrical connection to the ventilation unit.
WindMaker OCTAGON GGWC uses a very stable heat energy source, i.e. the ground, to improve air temperature parameters. The temperature at the depth of the ground-glycol heat exchanger foundation is relatively stable during a year, which guarantees energy saving benefits. Additionally, in winter, ground collector minimises the possibility of heat exchanger frosting or freezing the recuperator.
