Why Your Whole House Needs a Dehumidifier

Why your house needs a dehumidifier

There's a misconception that air conditioning systems can properly dehumidify the air in your home. In fact, most residents of Georgia can attest to coming home after a couple of weeks (or several months) to find that even though they had left the air conditioner running, the home smells musty.

Air conditioning systems are designed to control temperature, not humidity. If it's cool enough outside that you don't need to run your A/C, but it's damp enough that your home is uncomfortable, you might consider a whole-house dehumidifier.

According to Peter Blaha, Product Marketing Manger for Aprilaire, whole home dehumidifiers pull air from every room in your home through the return ducts. It removes the moisture and then sends dry air back throughout your home. It works in conjunction with your air conditioner to efficiently balance the humidity levels in your home, but can also work independently on days when you don't need the air conditioner.

He recommends keeping relative humidity levels below 60% in your home to keep mold and mildew from growing and to keep that musty smell at bay. There's been a growing awareness in Georgia for the need to manage humidity in the home with a crawl space dehumidifier. A whole-house system that's installed and ducted right into your air conditioning system is the way to go. The dehumidifier is installed to return the dry air before the AC heat pump system and will dehumidify the air for your entire home.

According to Aprilaire, daily activities such as cooking, cleaning and showering can add as much as 25 pounds of moisture to your home every day.

Blaha cautions against purchasing room-sized solutions from big box retailers. "Portable dehumidifiers treat the air in just one room" he says. "To properly control health, comfort and preservation throughout your home you would need to purchase a portable dehumidifier for every room. In this situation, you would consume more electricity than necessary."

"A more efficient solution is to have a single, whole-home central dehumidifier - a crawl space dehumidifier, or basement dehumidifier installed as part of your home's central heating and cooling system."

"Aprilaire Whole-Home Dehumidifiers are located out-of-sight and out of your way with quiet operation, hassle-free maintenance and up to four times more energy efficiency than the leading portable dehumidified."

"Our Aprilaire dehumidifier range will help by removing excess moisture and reducing the damage that mildew and mold can have on the sustainability of your home and the health of your family," he continues. "In addition, a whole home dehumidifier like Aprillaire's energy star rated 1730A can help qualify your home for the Green - Built Certification Program of the National Association of Home Builders"

Tips to maintain moisture during food processing

Food Processing Dehumidifiers

Food spoilage can occur when there are slight changes in relative humidity (RH), Moisture, which can condense on the surface of a product, can be one of the main causes of food contamination due to micro-organism growth. Microbial growth and dispersal can be controlled if the food processing facility is kept dry. Neither fans nor conventional refrigeration units will control humidity. Here are some useful guidelines to control moisture by using commercial dehumidifiers.

1. Traditional HVAC systems remove excess humidity by over cooling. By cooling the air to dew point, these systems pull humidity from the air through condensation. The condensation is collected on coils and drip pans, which often produces microbial build-up. To solve this problem, dehumidifying systems can be used.

2. Dehumidifiers come in two types - mechanical and desiccant. While a desiccant wheel costs more than a mechanical system, it does more dehumidifying than a mechanical system. Decision to use mechanical or desiccant dehumidifier will depend on the conditions of the plant.

3. A variety of food processing applications requires conditioned space to be maintained below 45°F dew-point humidity. For this, dehumidifying equipment in combination with refrigeration can be used for humidity and temperature control. A desiccant dehumidifying in combination with refrigeration generally is a more energy-efficient and practical method of producing low-humidity air than refrigeration alone. However, it is an energy-intensive process; the cooler and drier the process air, the more energy is required, regardless of which process is used.

4. If a desiccant dehumidifier is operated continuously and delivering fairly dry air, it is not unusual for annual operating cost to exceed the purchase price of the dehumidifier. This highlights the importance of making the desiccant dehumidifying process as energy efficient as practical.

Food and beverage processing requires large quantity of water, whether to cook, wash or sanitize. This often leads to increase in moisture level in the processing unit and also rise in temperature due to high humidity. Dehumidifying system can help control humidity, which greatly affects the quality of food.

5. Liquid desiccant, a natural salt water solution that removes humidity directly from the air, can offer an ideal solution to remove moisture. Because the units do not require the extra step of adding excess cooling or heating that conventional dehumidifying processes use, the liquid desiccant dehumidifying technology can reduce energy consumption by about 30 per cent, lowering the operating cost.

6. In addition to being energy efficient, liquid desiccant is also a natural disinfectant. The salt solution removes almost all air-borne bacteria and microorganisms in a single pass, and eliminates the need for drip pans or coils to collect condensation. Hence, the technology oilers additional benefits of improving air quality, removing odors and eliminating hazards associated with food safety.

7. In processing powdery food such as milk powders, moisture hinders the tree flow of powders/ granules making many downstream operations (ex: packaging, filtering and handling) difficult and expensive. In such cases, dehumidifiers, in conjunction with spray dryer/fluidised bed dryer, can be used to improve the quality of drying.

8. Desiccant dehumidifier is ideal for many temperature-sensitive products, which cannot be spray dried easily at relatively high inlet temperatures. Use of commercial dehumidifiers also reduces the drying time of the product inside the spray/fluidised bed dryer.

New Dehumidifier Range From Condair

Condair, the world's leading humidification specialist, is expanding its product portfolio with a range of advanced commercial and industrial dehumidifiers.

The new Condair dehumidifier range comprehensively covers both desiccant and condensing technologies with extensive standard capacities from 0.5kg/h to 182kg/h (@20°C/60%RH).

Custom commercial dehumidifier units are also available, which are capable of providing even greater dehumidifying or operating under specific or extreme environmental conditions required by an application.

Condair desiccant dehumidifiers use a silica-coated sorption rotor to absorb moisture from the air. This type of technology is ideal for low temperature conditions or applications that require very dry air, below 50%RH.

The dehumidifier's sorption rotor is regenerated with a heated airflow and the wet, hot air is vented externally. As standard, electrical heat exchangers are used for this regeneration process but gas-fired, steam or hot-water heat exchangers can also be used, either alongside the electrical heater or instead of it, to reduce energy and operating costs.
