Subatmospheric Vapor Pressures for Fluoromethane (R41), 1,1-Difluoroethane (R152a), and 1,1,1-Trifluoroethane (R143a) Evaluated from Internal-Energy Measurements

International Journal of Thermophysics, 1999
Vapor pressures were evaluated from measured internal-energy changes ΔU (2) in the vapor+liquid two-phase region. The method employed a thermodynamic relationship between the derivative quantity (∂U (2)/∂V) T , the vapor pressure p σ, and its temperature derivative (∂p/∂T)σ.

PVTx Measurements for the R116 + CO₂ and R41 + CO₂ Systems. New Isochoric Apparatus

Journal of Chemical & Engineering Data, 2005
A new isochoric apparatus was built for PVTx measurements in an extended temperature range from (210 to 360) K and at pressures up to 6.0 MPa. The setup was used to measure PVTx properties for the R116 + CO2 and R41 + CO2 systems, both in the two-phase and superheated vapor regions.

EJEKTÖR GENLEŞTİRİCİLİ TRANSKRİTİK SOĞUTMA ÇEVRİMİNİN R744, R170 VE R41 İÇİN TERMODİNAMİK PERFORMANSI

2018
On yıldan fazla bir süredir sıkı çevresel yönetmeliklerin küresel ısınma potansiyeli değeri kısıtlamalarına uyan çevre dostu soğutkanları bulmaya yönelik önemli bir arayış sözkonusudur. Aday akışkanlar arasından R744 (karbondioksit veya CO2), R170 (etan) ve R41 (florometan) bu çalışmada parametrik olarak incelenmek için seçilmiştir.
