Heat pump performance varies with the outside temperature, solar gains and internal gains inside the house. How do cold climate heat pump respond to these variables? It depends.... This session will present real world minute and hourly heat pump meter data benchmarked to EnergyPlus simulation predictions for a range of cold-climate heat pump systems. Common performance problems will be explored, and strategies for avoiding high customer bills will be presented.
Learning Objectives:
By attending this session, attendees will:
Understand how weather and indoor loads combine to impact variable speed heat pump performance in cold climates
Understand how heat pump oversizing can impact a customers energy bills
Understand how heat pumps can inadvertently cause high energy bills
