Humidifiers are generally classified according to their applications and working principle. Each category has its pros and cons. Basing on applications, dehumidifiers are regarded to be either portable or industrial. When it comes to working principles, these appliances are categorized as a desiccant type or refrigerant type.
Indoor Pool Dehumidifiers
These dehumidifiers are mostly installed indoors in spas, Jacuzzis, and rooms that have heated pools. They are also fitted on ceilings, walls, and floors. In most cases, wall-mounted indoor dehumidifiers have a limited capacity. Therefore, they are only used in rooms that have small swimming pools. Roof-mounted indoor dehumidifiers have a larger capacity. This makes them suitable for rooms that have larger pools.
Refrigerant Type Dehumidifiers
These appliances are also referred to as condenser drying, condensation type, or mechanical dehumidifiers. They use the refrigeration cycle to lower humidity levels. The humidifiers come with a condenser coil and an evaporator. The fan attracts humid air to the evaporator, where it is chilled below dew point to condense into water. The water is then collected in a tank. Refrigerant type dehumidifiers are recommended because they are cheap to buy and use. They are similarly energy efficient.
Desiccant Type Dehumidifiers
These units consist of a rotating desiccant wheel. Humid air is drawn to the wheel by a fan. The wheel absorbs all moisture and releases dry air back into the rooms. As a result, the wheel often gets wet. To dry it, hot air is passed through the system. Desiccant type dehumidifiers are preferred because they are also cost effective. Besides this, they can work perfectly in rooms that have low temperatures and humidity levels.
Before you purchase a dehumidifier, several factors ought to be considered. This will help you overcome the confusion that is associated with making this decision. These factors include size, a temperature range of the appliance, energy use and efficiency, noise level, water removal mechanism, and mobility.
