Munters - Dehumidification / Humidification / Cooling. Munters Desiccant Rotor Technology. Munters desiccant dehumidifiers attract moisture from the air by creating an area of low vapour pressure at the surface of the desiccant. The pressure exerted by the water in the air is higher, so the water molecules move from the air to the desiccant and the air is dehumidified. Munters desiccant dehumidifiers make use of changing vapour pressures to dry air continuously in a repeating cycle described by the simple diagram below. As the desiccant picks up moisture from the surrounding air, dry air is discharged to the process area and the reactivation air stream discharges the wet air outside. Munters units can operate in a wide range of temperatures, including at low temperatures down to - 4. Adiabatic Cooling Plate heat exchanger for refrigerant-free supply air cooling (gentle cooling) By the adiabatic cooling (indirectly evaporative), a cooling of around 10 C (for example from 32 C to 22 C) can be reached environmentally friendly, without cold. Hot intake air is detrimental to power and will increase the chance of detonation. An intercooler reduces the intake temperature by pushing the air through a heat exchanger (like a small radiator) that absorbs some of the heat from the intake air. Placing an intercooler.

XIV Contents 1.5.2 Physical basic principles of ideal gases 44 1.5.3 Standard temperature and pressure 52. Power. Purge saves energy in two ways. The unique patented Power. Purge acts as an energy recovery system, collecting waste heat off of the hottest section of the desiccant wheel and using it to help with the regeneration by pre- heating the coolest part of the rotor. This reduces the energy required for reactivation while also reducing the discharge temperature of the process air, resulting in lower energy costs for post- cooling. Power. Purge can also save on first cost. Equipping a desiccant system with Power. Purge can reduce the size of the desiccant rotor without diminishing the dehumidification capacity. Benefits of Munters Power. Purge. A distribution pad on the top of the cooling pad ensures an even water distribution. The water flows down the corrugated surface of the GLASdek evaporative cooling pad. Part of the water is evaporated by the warm and dry air that passes through the pad. The heat that is needed for the evaporation is taken from the air itself. The air that leaves the pad is therefore cooled and humidified simultaneously without any external energy supply for the evaporation process. This is nature’s own cooling process. Modular design fits all AHUs. For airflows from 0. Munters award winning Oasis. Power Engineering Dictionary Power Engineering Dictionary. ABMA - . American Boiler Manufacturers Association.
