Description (excerpt):
This report covers the long-term performance of mini-split heat pumps (MSHPs) in Massachusetts (zone 5A); it is the culmination of up to 3 years’ worth of monitoring in a set of eight houses. This research examined electricity use of MSHPs, distributions of interior temperatures and humidity when using simplified (two-point) heating systems in high performance housing, and the impact of door open/closed status on temperature distributions. The use of simplified space conditioning distribution (MSHPs) provides significant first cost savings, which are used to offset the increased investment in the building enclosure.
