How to Remove Humidity from a Room

A spot cooler can be used to remove humidity from a room. They are often employed in server rooms and other high-heat areas where humidity is a common and consistent issue. Florida is known as the most humid state in the US. With a near tropical climate and close proximity to the warm waters of the Gulf of Mexico, as well as the Atlantic Ocean, South Florida tends to be incredibly humid. Humidity can cause issues for businesses because it is hard on materials and people, especially electrical equipment found in a server room.

Humidity is much worse than heat and it has a corrosive effect on computer equipment, and even interior finishes like paint and metal. Not to mention, high humidity is uncomfortable to hang out in and leaves people feeling sticky, and maybe even grumpy. In addition, humid rooms are more susceptible to mold growth, allergens and mildew. There are a lot of reasons why you’d want to remove humidity from a room. So, how do you do it?

Using a Spot Cooler to Remove Humidity

A dehumidifier is a common piece of equipment used to stabilize moisture in the air. A spot cooler or air conditioning unit works in a similar fashion, while adding the bonus perk of cool air. Both dehumidifiers and air conditioners rely on a similar set of parts including a compressor, metering device, condenser, and evaporator.

An AC system pulls in hot air and then evaporator coils work to condense the air and draw out moisture. That means, hot moisture leaves the air as it makes contact with the cold coil. Moisture builds up on cooling coils and is filtered out of the area, creating a cooler and less humid space. 

To better understand how it works, here’s a step-by-step process of how a spot cooler operates:

  • A fan on the machine pulls in hot air from the room.
  • The compressor goes to work removing heat and moisture from the air by pressurizing refrigerant and turning gases into a hot liquid.
  • This hot water is transferred to the condenser where heat is released through specially placed vents. When the refrigerant meets the coil end, it is pressurized.
  • The metering device stops liquid refrigerant from entering the evaporator. The metering device depressurizes the refrigerant so that it can evaporate into a gas.
  • The air released back into the room is cooled off. This process strips the air of hot moisture, hence how humidity levels decrease.
  • Heat is removed via the venting system, and hot air is directed into the unit via AC tubes.

The Importance of Low Humidity

High humidity levels are not good for equipment or people. Therefore, many businesses make it their priority to reduce humidity levels as much as possible. High humidity levels can also be detrimental to construction sites because materials cannot properly dry and adhere to surfaces. For successful construction drying, humidity levels should fall between 25% and 55%, with temperatures between 60 and 70 degrees F.

Rent or Buy Spot Coolers to Reduce Humidity

You can rent or buy spot coolers from Cooling Power to reduce humidity. Renting spot coolers is an excellent option if you are working on a short-term project or event, or if you need to reduce humidity levels seasonally. For instance, in Florida it gets very warm and humid in the summer. That’s why many businesses rent spot coolers for the summer to reduce humidity. They can return the spot cooler in the fall when it is no longer needed and don’t have to worry about storing or maintaining the spot cooler.
