WebJun 18, 2014 · Project Objective. This project is developing a split-system, cold climate heat pump (CCHP) that provides a nominal heating capacity of 36,000 Btu/hour (3 tons) with a COP of 4.0 at the 47°F ambient temperature standard rating condition. In addition, heating capacity at -13°F ambient conditions is to be ≥75% of the nominal capacity. WebJan 1, 2016 · In cold climate zones, e.g. ASHRAE climate regions IV and V, conventional electric air-source heat pumps (ASHP) do not work well, due to high compressor discharge temperatures, large pressure ratios and inadequate heating capacities at …
