Heating is by far the biggest consumer of energy in buildings, accounting for 25-43% of total energy use. Air source heat pumps have gained popularity in moderate climates due to their high efficiency; however, their performance has traditionally degraded steeply in cold climates. Cold climate heat pumps are designed to maintain capacity and efficiency even in extremely cold climates. This seminar will focus on applications and design considerations of cold climate heat pumps by discussing current
installations in the field and research and development prototypes that further improve cold climate heat pump performance.
