    "description": "These data from the laboratory tests of a prototype residential liquid-to-air ground-source air conditioner (GSAC) using CO2 as the refrigerant.  The data collection and processing methods are described in detail in this report:\n\nReport Title:  \"Laboratory Tests of a Prototype Carbon Dioxide Ground-Source Air Conditioner\", NIST Technical Note 2068\nPublication Date: October 2019\nDOI: https:\/\/doi.org\/10.6028\/NIST.TN.2068\nAuthors: Harrison Skye, Wei Wu\n\nThe tests were performed in an environmental chamber and followed the ISO 13256-1 standard for rating GSHPs.  The CO2 GSAC operated either in a subcritical or a transcritical cycle, depending on the entering liquid temperature (ELT).  The test results included the coefficient of performance (COP), capacity, sensible heat ratio (SHR), and pressures.  The system incorporated a liquid-line\/suction-line heat exchanger (LLSL-HX), which was estimated to cause a COP penalty of (0 to 2) % for ELTs ranging (10 to 25) \u00b0C, and benefit of (0 to 5) % for ELTs ranging (30 to 39) \u00b0C.  With ELTs ranging (10 to 39) \u00b0C the CO2 system cooling COP ranged (7.3 to 2.4).  At the standard rating condition (ELT 25 \u00b0C), the CO2 GSAC cooling COP was 4.14, and at part-load conditions (ELT 20 \u00b0C) the system had a COP of 4.92.",
