Multifunctional run-around coil systems

Multifunctional run-around coil systems are based on straightforward RCS with an additional heating or cooling coil fitted into the medium circuit. Heating and cooling can also be controlled on and off hydraulically.

Multifunctional RCS are particularly suitable where space on site is at a premium, as no additional heat exchangers on the air side within the air handling unit are required. However, with such systems, it is inevitable that the heat recovery will become less efficient when additional energy is fed into the system.
