The refrigerant R 245 fa is selected due its good thermal transfer and control low temperature refrigeration and industrial process air cooling and refrigeration. 2.2. About R 236 fa Hexafluoropropane 236 fa is a HFC used as fire retardant, refrigerant, spraying agent, the rest of exergy after the heat exchanger that is not further used
The working fluids studied were R134a R245fa R245ca R123 pentane isohexane from CHEM 60614 at University of Notre Dame
Thermo-economic comparison of air-cooled and cooling This work presents the economic modeling and analysis of a thermoelectric steam power plant (SPP) cooled with an air-cooled heat exchanger (ACHX) and using an absorption refrigeration system (ARS
An automotive vehicle cooling system is provided, wherein refrigerants are condensed and vehicle oils are cooled in a single unitary heat exchanger mounted forward but spaced apart from the engine radiator in the air path of the engine fan. A vehicle oil conduit is passed through the bottom tank of the engine radiator, and thence through the heat exchanger to efficiently cool the vehicle oil
Investigations of thermal performance of ejection Feb 05, 2018 · Alternative refrigerants from common solvents including acetone, benzene, toluene, and non-flammable synthetic refrigerants from R-236 and R-245 groups have been numerically tested by Gil and Kaspersky . The authors carried out series of simulations of the ejection cooling systems for the generator temperature between 70 and 200 °C.
