South FloridaCASE STUDY
Issue ReportedEfficiency and one-bedroomapartments were experiencingelevated relative humidity (RH) forextended periods of time resultingin resident complaints, mildew andin some cases mold growth.
Type / ConstructionConcrete construction withstucco finish.
Location South Florida
Background
ProcessThe first IW-25 in-wall dehumidifier was installedadjacent to the living room of a one-bedroom unit.An iMonnit data logging system was placed andhumidity sensors were placed inside and out tomonitor temperature and relative humidity (RH).
Innovative Dehumidifier Systems was contacted byproperty management at this South Florida luxuryapartment property to resolve various moisturerelated problems inside apartments. Mechanicalsystem design included unconditioned outside airbeing introduced into mechanical closets.Additionally, some of the one-bedroom units wereserved by 2-ton split air conditioners which weregrossly over-sized.
Prior to the installation of the IW-25 in-walldehumidifier, some of the two-ton air conditionerswere replaced by 1.5 ton units with someimprovement; however, RH remained elevated.
CASE STUDYSouth Florida
Outdoor RH ranged between 70% and95% during the monitored periodAverage RH was in excess of 86%RHMoisture-laden outside air was beingintroduced into apartments
Ambient Humidity - Outside Air
Monitoring unit 311 - Bathroom
Conclusion
Indoor RH prior to installation of theIW-25 ranged between 67% and 78% RHAir-conditioner run cycles weredocumented as short at 4.5 minutesRH was maintained at safe andacceptable levels between 52% and56% after the IW-25 was installed
Monitoring unit 311 - BathroomSecondary sensors were placed inthe bathroom to take additionaltemp & RH dataData measurements wereaccumulated every 10 minutes
Prior to the installation of the IW-25 in-wall dehumidifier, thousands of dollars were spenton ineffective corrective action including consulting engineers, replacement mechanicalsystems and temporary solutions such as portable dehumidifiers. Not only was the IW-25the most effective solution for this application, it was by far the least expensive.
