Many buildings require substantial amounts of outside air to be brought in through their ventilation systems. In many cases it is code ( schools) and in other cases it constitutes make up air for contaminated exhaust air (laboratories). Regardless, exhausting expensive conditioned indoor air and replacing it with outdoor air is really expensive. Energy recovery devises, like the Enthalpy Wheel, can be incorporated in the design to transfer outgoing temperature and humidity (energy) to the incoming outdoor air.
The process takes place with no energy use due to the passive nature of the heat pipe. The result is an air conditioning system with the ability to remove 50 to 100% more moisture.
When we use less energy, the less energy we need to generate at power plants, which reduces greenhouse gas emissions and improves the quality of our air. Energy efficiency helps the economy, too, by saving consumers and businesses millions of dollars in energy costs
A desiccant dehumidifier operates on a totally different principle to a refrigerant type. The main benefit of a desiccant dehumidifier is that it performs exceptionally well when used in cooler climates, or when a low dewpoint is required. As there is no actual water produced during the process, these units can work effectively at sub-zero temperatures.
