It is used to maintain dryness, whether preserving food products or preventing moisture damage to electronics or medications. Desiccants absorb the humidity and moisture in the air to maintain a moisture-free environment, which is essential to prevent damage, corrosion, bacteria and mold growth.
A Heat Recovery Ventilation system (HRV) also known as mechanical ventilation heat recovery (MVHR) is an energy recovery ventilation system that uses an air-to-air heat exchanger that recovers normally wasted heat while at the same time supplying fresh highly filtered air improving the indoor environment.
An Air Handling Unit (AHU) is a device that regulates and circulates air in a building as part of a heating, ventilating, and air-conditioning (HVAC) system. AHUs collect air from inside and outside, remove particles, adjust the temperature and humidity, and then distribute the conditioned air throughout the building.
An enthalpy wheel is a type of rotary air-to-air heat exchanger that transfers heat and moisture from one air stream to another. An enthalpy wheel is a rotating, porous wheel that passes through two air streams, one supply and one exhaust. The wheel stores heat from the warmer air stream and transfers it to the cooler air stream.
An enthalpy wheel can save energy by reducing the need for heating in the winter and cooling in the summer. It can also save money because removing moisture can cost 30–50% of the cost to condition air.
Refrigerant Dehumidifiers work by creating a cold surface that is colder than the air around them. The appliance has a fan that draws air over a cool metal plate, where the moisture condenses and then drips into a water tank.
