Heat pumps based on the vapor compression platform are here to stay, as an entire new family of products are
beginning to work their way into the market. Variable capacity advancements are enabling what was an inherently single-speed, single-capacity technology, to mature into an advancement better able to match capacity to load. This capacity flexibility can make advanced heat pumps an attractive tool for electric grid demand control.
Unfortunately that flexibility is difficult to characterize through the established methods of rating, and likewise
difficult to promote through existing channels. There is much work to be done in properly describing the potential of this technology family, in the laboratory, in the field and in modeling Tools.
