Vertical farming is an agricultural method in which crops such as leafy greens and herbs are farmed indoors within climate-controlled environments. As the process becomes more efficient and economically viable, these urban farms are becoming more prevalent across the United States.
By controlling important environmental factors indoors, growers are able to cultivate better-quality crops at higher yields and in shorter periods of time. This also reduces the human footprint on the environment, as water and nutrients are conserved and less pollution and emissions are generated.
Whether using dehumidification for industrial, commercial, residential, or swimming pool applications, customers must determine, if applicable, which of the two typical cooling system options will be the best fit for their application — air cooled or water cooled.
Air cooled dehumidifiers, for indoor pool room dehumidification and other projects, are the most common type and deliver warm dry air back to the space when operating. When room cooling is needed they are coupled with an optional outdoor remote condenser. This allows them to deliver warm dry air or cool dry air depending on what the controls call for.
Humidity is a major concern for all indoor swimming pool owners. Air-to-air heat exchangers and ventilation systems were commonly used to control pool room humidity.
These methods are expensive to operate and wasteful, in that they constantly exhaust previously heated or cooled air outdoors. They also often fail to prevent structural damage caused by excess moisture, as the formation of mold and mildew in cold walls can cause irreparable damage.
The most effective way to control pool room humidity is to use a full dehumidification system that serves to remove destructive moisture and add room heating as a by-product of the dehumidification cycle.
Hotel, motel, and residential indoor pool rooms are just a few scenarios where you can find dehumidification systems controlling the relative humidity. An unexpected failure of a dehumidification system in these facilities can have some considerable negative impacts.
A malfunctioning dehumidification system can cause mold and mildew build up quickly. This can lead to musty smells and poor air quality, not to mention structural issues.
Malfunctioning dehumidification systems can also lead to unhappy customers and bad reviews, which could hurt a business. In an industrial setting, a manufacturer can lose a large amount of money in downtime, missed deadlines, or ruined product when relative humidity is out of control.
The mission of Dehumidifier Corporation of America (DCA) has been to provide customers with high quality dehumidification systems solutions at competitive prices. That has been our primary goal since our founding in 1995.
DCA has always provided the highest quality brand name, off-the-shelf, non-proprietary dehumidifier components, easily obtained from any quality refrigeration distributor. This is especially important when it comes to the control system. DCA has never specified proprietary controls on any of our products. This allows repair technicians the advantage of sourcing controls and many other dehumidifier parts from their local supply house, as opposed to waiting for the factory to react.
As anyone who pays an electricity bill can tell you, air conditioners can use a tremendous amount of electricity. When that increased usage is applied across a large population, such as the New York, Madison, or Los Angeles metropolitan areas, the power grids serving those areas are put under a tremendous amount of strain.
Dehumidifier Corporation of America (DCA) designs dehumidification systems for a wide range of applications. We have provided dehumidification solutions to hotel and motel chains, homeowners and manufacturing facilities where the control of relative humidity is critical. No matter what kind of building you operate, summer humidity can pose a real problem. High humidity is a particular threat for facilities that store sensitive items that can be ruined by moisture, like food or powdered products that take on moisture.
What is Humidity?
Humidity can be measured as both relative and absolute. Absolute humidity refers to the mass of water vapor divided by the dry air mass, within a volume of air at a known temperature (see HowStuffWorks for more information). As the temperature of the air rises, the potential of water content increases.
Humidity is most-often measured in relative terms. Relative humidity is the ratio of the absolute humidity to the highest possible absolute humidity. A 100% relative humidity signifies total saturation, leading to the formation of rain droplets. People are most comfortable at a relative humidity 40-60%: any higher and natures air conditioner will slow down sweat from evaporating at an efficient rate and therefore the air will feel hotter to the body than it actually is.
Why is Humidity Harmful?
In addition to discomfort, humidity can also lead to structural problems, causing mold and mildew growth. Excess moisture can rot wood framing, which reduces structural integrity and provides a breeding ground for mold and pests. This is dangerous for occupant health because mold and mildew are known to cause respiratory problems, allergic reaction symptoms, nervous-system disorders and even depression.
Limitations of Air Conditioners When Combatting Humidity
A.C. systems effectively cool indoor spaces and remove some moisture, but they also raise the relative humidity indoors. This often results in mold and mildew accumulation in air moving duct work, which results in poor indoor air quality and “sick building syndrome”. ASHRAE standards now stipulate that all buildings must dehumidify outdoor air before sending it to the HVAC system.
Solve Your Summer Moisture Challenges with DCA
We can help you improve the moisture control of your system and get summer moisture under control, ultimately saving you money and energy in the long run. With the right equipment, it is possible to achieve optimal climate control year-round for the products and people inside your facility.
Dehumidification plays a key role in the housekeeping maintenance of waste and fresh water treatment facilities. Metal surfaces such as holding, treatment and filtration tanks, pipes and pump room equipment are exposed to cold water that often brings their surface temperature below the room’s dew point temperature. When this happens, moisture forms on these surfaces causing rusting and corrosion.
During warm months, just about every location east of the Rocky Mountains feels the muggy effects of high dew points. The resulting high relative humidity produces a host of issues for businesses such as printing, machining, archive storage, food packaging, electronic component providers and clean rooms.
As moist air takes over in summer, manufacturers often struggle to maintain consistent room moisture. Even with air conditioning, relative humidity can rise to unacceptable levels for equipment operation and product integrity. The only solution is to add a dedicated dehumidification system to remove unwanted moisture while maintaining a desired room air temperature.
