Desiccant dehumidifier how it works

The silica gel gives away the moisture in to the reactivation airflow by means of evaporation of water in to the hot air flow that has increased capacity to be saturated with water vapor. The warm and humid airflow then is exhausted to the outside of the desiccant dehumidifier. Thus, in the same way in which the chemical and physical properties of a chemical refrigerant allows for the proper functioning of compressor based dehumidifiers , the chemical and physical properties of desiccants allow for the proper functioning of desiccant dehumidifiers. While refrigerative dehumidifiers may be the most well-known, desiccant dehumidifiers also do a great job of keeping a space nice and dry. True to their name, these dehumidifiers pull in air and pass it over a desiccant material such as silica gel.

This function of a desiccant dehumidifier requires a high level of power consumption.

Fixing my unreliable desiccant dehumidifier again. In theory they are a great evolution of the refrigerant based systems, but this one is not great. Regardless, they are quite interesting to see.

TOP Presently there are dehumidifiers for little workplaces and homes so individuals can procure the same advantages. These are portable models that you can purchase at retail locations or online. A fan draws air into the dehumidifier and passes it through a section of a slowly rotating wheel which holds desiccant which dries the air.

Dehumidifying Ventilator – Similar to how it sounds, this humidifier works by using an exhaust fan to expel air outside. It uses a sensor and exhaust fan and is most often used in basements, attics, and crawlspaces.

They work by creating a cold surface and when the warm, damp air from within the room comes into contact with the cold surface condensation forms and the water is removed from the air. The dehumidifier reheats the air and exhausts it back into the room. There are numerous sorts of dehumidifiers in the business sector, why just choosing the desiccant dehumidifier ? Since it is the best and dependable in view of the major parts working in one unit. The material draws the moisture out and dries the air which then exits the unit. The air to be drie or process air, is ducted through the rotor in one air stream.

The rotor brings the moist desiccant to the reactivation air stream to heat it up. Dehumidifiers absorb moisture from the air into desiccant materials. Moisture is expelled from the desiccant material as water vapor. Moist, warm air is ducted outdoors. Many residential units contain single-use desiccant-type cartridges, gel, and powder.

When air is drawn into the dehumidifier , it touches cooling coils which pulls moisture from the air through lowering the temperature. Because the coils are colder than the air around them, as the air cools, the moisture it contains condenses. Free of moisture, the now cooled air is then reheated to its original temperature which is. There are different types of dehumidifier : the refrigerant and the desiccant. The refrigerant type condenses moisture out of the room air.

This is how the condensation happens which is then. FAQ’s about desiccant dehumidifiers.

How does a desiccant dehumidifier work? The wheel is now saturated and needs to be regenerated. Refrigerant (or compressor) dehumidifiers. It’s often claimed that desiccant dehumidifiers tend to use more energy than refrigerant dehumidifiers because of the way they use heat to warm the adsorbent material. In these integrated designs, the desiccant system works as a pre-conditioner for outside (ventilation) air to remove the latent load.

Other applications of desiccant dehumidification are in ice rinks, hotels and motels, office buildings, full-service and fast food restaurants, medical facilities, and retirement homes. Moisture laden air is drawn through the rotor in the process air stream. The desiccant embedded in the rotor “soaks-up” this moisture and holds on to it.

Desiccant dehumidifiers also work better at a greater range of temperatures, particularly in cooler environments. In fact, at lower temperatures, desiccant dehumidifiers are more efficient than compressors. If you’re fighting a battle against humidity in your home or business, a desiccant dehumidifier can be an excellent choice and improve your living conditions. When the air comes into contact with the desiccant the moisture is retained by the desiccant granules.

When the moisture is heated some of it will fall down into the water tank and some of it will vaporize. A desiccant is a substance that attracts moisture from the air. Eva-Dry specializes in desiccant dehumidifiers, which allows them to be lightweight and easily portable. There are two primary dehumidifiers on the market today – the refrigeration type of dehumidifiers and desiccant dehumidifiers. Each of these types of dehumidifiers has unique attributes that make them suitable for different uses.

This desiccant is impregnated into paper sheets which are then wound into a wheel (called the rotor). The rotor is divided into two sectioned air streams: the process section and the reactivation section. When this moisture is adsorbed by a desiccant dehumidifier it doesn’t change state. It’s adsorbed as a vapor (for more information on how desiccant dehumidifiers work see here). Instead of using a compressor to cool refrigerant coils, these machines use a desiccant wheel (moisture absorbing) to soak up water.

A heater inside the machine is then used to renew the desiccant material. The process air outlet is both cooler and drier when compared to other desiccant dryers. Most of our dehumidifiers operate on this principle. Can be used on both ‘open’ and ‘closed’ type systems. Additionally, some dehumidifiers , especially the desiccant models come with ionizers built in.

It uses a chemical called desiccant – hence the name – to soak up moisture in the air. A Low-Tech Solution to a High-Tech Problem. An indoor environmental systems professional can help determine what kind of dehumidifier commercial models will work the best for your business needs. They are often used in various sectors in the industry because they can achieve humidity levels below.

Desiccant -based systems are more economical than refrigeration systems at lower temperatures and lower moisture levels. Typically, a desiccant dehumidification system is utilized for applications below RH down to RH. Thus, in many applications, a DX or chilled water pre- cooling coil is mounted directly at the dehumidifier inlet. They use a different process than the traditional dehumidifier.

The air from the room is blown over discs that contain material that naturally absorbs moisture. When the air reaches the other side of the wheel it is dry and pushed out of the unit by a high static blower. There’s more to it than that but that’s the brief explanation of how a desiccant dehumidifier works.

Eva-Dry mini dehumidifiers are safe to use in the home, vehicle, RV, gun safe or virtually any other space where moisture and humidity is an issue.
