The program incorporates evaporator and condenser models from EVAP-COND, a stand-alone simulation tool developed by NIST for air-to-refrigerant heat exchangers ( https://www.nist.gov/services-resources/software/evap-cond-version-50). Consistent with EVAP-COND, ACSIM uses refrigerant thermophysical properties based on the NIST Standard Reference Data 23; NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP): Version 10.0 (http://www.nist.gov/srd/nist23.cfm) and uses refrigerant property look-up tables to facilitate fast simulations. ACSIM installation module does not provide REFPROP fluid files, which need to be loaded by the user after ACSIM installation.", "distribution": [{"accessURL": "https://data.nist.gov/od/rp?@id=ark:/88434/mds2-3946", "description": "This page provides a registration form that must be completed before downloading the data.", "title": "Gateway for Registered Data Access"}, {"description": "A tutorial on using ACSIM", "downloadURL": "https://data.nist.gov/od/ds/mds2-3946/Instruction_Pages_1.0.pdf", "format": "A pdf file", "mediaType": "application/pdf", "title": "Instruction Pages"}, {"description": "An installation module for the Look-up Table Generator (TableGen2).
