WebCoefficient of performance. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. WebNov 8, 2024 · Under DOE’s CCHP Challenge, a heat pump 4 tons and lower must have a COP of 2.4 while providing 100% of nominal rated capacity at an ambient temperature of 5°F (see Table 1). A heat pump larger than 4 tons must have a COP of 2.1 with the same nominal capacity requirement at 5°F.

This method has been used in the aerospace industry for about thr ee decades for supporting system-level design analysis. WebDescription A professional reference title written primarily for researchers in thermal engineering, Combined Cooling, Heating and Power: Decision-Making, Design and Optimization summarizes current research on decision-making and optimization in combined cooling, heating, and power (CCHP) systems.
WebThe air-to-air (A2A) CCHP replaces a furnace and air conditioner to provide year round heating and cooling, and provides sufficient heat for approximately 50% to 70% of a household’s annual hot water needs. The MURB CCHP is a multi-unit residential building (MURB) version of the A2A CCHP. 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.
