Who's Leading: The Dance Between Mini-Splits And Existing Hvac Systems, Florida Solar Energy Center, Cheryn Metzger
Who's Leading: The Dance Between Mini-Splits And Existing Hvac Systems, Florida Solar Energy Center, Cheryn Metzger

Recently, many utilities across the U.S. have provided incentives for ductless mini-split heat pumps due to their relatively high efficiencies. However, when these ductless mini-splits are installed in existing homes, utilities and researchers find that they are not living up to their energy saving potential, due to a lack of coordinated controls with the existing HVAC system. The Pacific Northwest National Laboratory (PNNL), the Florida Solar Energy Center (FSEC), and The Levy Partnership are all leading projects across the country to address this problem. The goal for this body of work is to determine which control strategies provide the most …

Characterization Of Mechanical Ventilation Systems In New Us Homes: What Types Of Systems Are Out There And Are They Functioning As Intended?, Florida Solar Energy Center, Eric Martin

As the airtightness of homes improves to meet energy efficiency goals, it becomes more important for mechanical ventilation systems to help maintain a comfortable and healthy indoor air environment. ASHRAE Standard 62.2 provides national guidance for mechanical ventilation system design and installation, however adoption of those guidelines into local building codes has occurred at different rates. Once provisions for mechanical ventilation are adopted in a local code, are mechanical ventilation systems properly designed, installed, commissioned and operated according to code or above-code program requirements? This paper presents results from field studies that include characterization of whole house mechanical ventilation (WHMV) …

Side-By-Side Testing Of Solaire Solar Ac, Florida Solar Energy Center, John Sherwin

The FSEC Energy Research Center performed a series of side-by-side tests to compare a heat pump system with a SolAire thermal collector against one without. The tests were performed in three phases: 1) baseline operation, 2) heat pump system operating with SolAire collector using collector manufacturer's wiring specifications, and 3) heat pump system operating with SolAire collector using Daiken/OEM wiring specifications. Each phase represented 5 full days of continuous operation during August of 2018 in Cocoa, Florida. Phase 1 baseline testing demonstrated that the two Daiken heat pump systems and test houses performed similarly and there were no differences between …
