Technical Subtopic 2.1: Modeling Variable Refrigerant Flow Heat Pump And Heat Recovery Equipment In Energyplus: Task 4.0 - Independent Lab Testing Of Two Vrf Ac Systems In Heat Pump And Heat Recovery Mode

Two Variable Refrigerant Flow (VRF) heat pumps were tested at the Electric Power Research Institute\u27s (EPRI) Knoxville, TN laboratory. These systems were not tested in accordance with the Standard methodof test as described by ANSI/AHRI Standard 1230. Instead, these systems were tested in an attempt to measure performance as if these systems were field installed. The following report is considered to be an independent third party document and was prepared in its entirety by EPRI to describe the VRF systems selected for test, the unique laboratory used during these tests, and the results of said testing. The tests were completed in February, 2012 with final editorial comments provided on February 22, 2013
