Hymod Hymod is the market's first local hydraulic network balancing module that is designed to ensure variable flows in secondary circuits and thus optimise the energy efficiency of heating or cooling systems. Designed in particular for systems of up to 3,000 m2 in size, Hymod supplies comfort units with water at the right flow rates for each use. Hymod improves the energy efficiency of ancillary equipment by as much as 40%. With the tightening of the EU's F-gas Regulation on fluorinated refrigerants, water-loop-based systems have once again become the natural solution for building heating and cooling needs. CIAT's Hysys® system is an advanced, comprehensive solution for the operation of water-based systems. Its Hymod balancing module for secondary networks optimises Hysys® even further. When installed between a chiller or a heat pump and emitters (comfort units), Hymod isolates primary and secondary hydraulic networks. It meets regulatory requirements on network balancing, ensures the distribution of water to each emitter, and guarantees that heating and cooling systems are easy to operate, efficient and in compliance with requirements. It consists of a balancing valve on the primary network, a primary bypass and a variable flow (0-100%) accelerator pump that adjusts water flow rates to the needs of emitters fitted with power-efficient motors. Placed in zones, Hymod meets flow rate requirements of up to a maximum of 6 m3/h (35 kW capacity). Hymod takes the hassle out of installation. Each module is calibrated and commissioned by CIAT's teams during the commissioning of entire heating or cooling systems, freeing fitters to do other tasks. Because it is installed locally in suspended ceilings in building zones, it frees up significant space in mechanical rooms. 1/2

On the primary network side, the Hymod isolator is fitted with a balancing valve that adjusts the nominal flow rates required in their zone. Such head-end balancing is required by Article 23 of France's 2012 thermal regulation. Water is supplied by the low-pressure pump installed in the thermodynamic machine. On secondary networks, the Hymod isolator is fitted with an EC accelerator pump that adjusts water flow rates to the requirements of comfort units in real time and by independently managing the constant differential pressure. Comfort units must be fitted with self-balancing two-way valves....
