Refrigerated air conditioning equipment usually reduces the humidity of the air processed by the system. The relatively cold (below the dewpoint) evaporator coil condenses water vapor from the processed air, (much like an ice cold drink will condense water on the outside of a glass), sending the water to a drain and removing water vapour from the cooled space and lowering the relative humidity. Since humans perspire to provide natural cooling by the evaporation of perspiration from the skin, drier air (up to a point) improves the comfort provided. The comfort air conditioner typically creates a 40 - 60% relative humidity in the occupied space. In food retailing establishments, large open chiller cabinets act as highly effective air dehumidifying units. Humidification is often necessary in colder climates where continuous heating will make the air drier, resulting in uncomfortable air quality and increased static electricity. Various types of humidification may be used, but generally in air conditioning or climate control, evaporative coolers are used where dry air is blown over a reservoir evaporating some of the water

Portable Humidifiers

Humidification is often necessary in colder climates due to continuous heating drying out the air, resulting in uncomfortable air quality as well as increased static electricity. The addition of electeronic manufacturing, computers and servers which can also lower sensible humidty levels creating further static and dryness.

There are multiple types of humidification that can be used and include: Evaporative - where dry air is blown over a reservoir which will evaporate water. The rate of evaporation can be increased by spraying the water onto baffles in the air stream. Vaporizer - where steam or vapour from a boiler is blown directly into the air stream. Spray mist when water is diffused either by a nozzle or other mechanical means into fine droplets and carried by the air.
