This research project evaluated the energy impacts and dehumidification performance related to how ducted dehumidifiers (DHU) ducts were configured. Lab controlled testing over a variety of weather and latent loads evaluated five-different ducted DHU configurations as follows: Test 1 DHU air ducted from/to the central main body of building. Test 2 DHU air ducted from/to return side of central air conditioner (AC). Test 3 DHU air ducted from/to supply side of AC. Test 4 DHU air ducted from central main body and ducted to supply side of AC. Test 5 DHU air ducted from outdoors and indoors mixed before DHU …

The well-sealed, highly insulated building enclosures constructed by today's home building industry coupled with efficient lighting and appliances are achieving significantly reduced heating and cooling loads. These low-load homes can present a challenge when selecting appropriate space-conditioning equipment. Conventional, fixed-capacity heating and cooling equipment is often oversized for small homes, causing increased first costs and operating costs. Even if fixed-capacity equipment can be properly specified for peak loads, it remains oversized for use during much of the year. During these part-load cooling hours, oversized equipment meets the target dry-bulb temperatures very quickly, often without sufficient opportunity for moisture control. The …
