Finalize field testing of cold climate heat pump (CCHP) based on tandem vapor injection compressors
- Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)
This report describes the system diagram and control algorithm of a prototype air-source cold climate heat pump (CCHP) using tandem vapor injection (VI) compressors. The prototype was installed in Fairbanks, Alaska and underwent field testing starting in 09/2016. The field testing results of the past six months, including compressor run time fractions, measured COPs and heating capacities, etc., are presented as a function of the ambient temperature. Two lessons learned are also reported.
