Summary

The possibility of using R134a as a refrigerant in combination with different organic absorbents, such as dimethylether tetraethyleneglycol (DMETEG), N-methyl epsilon-caprolactam or dimethyl-ethyleneurea, in absorption units was investigated. The procedures in the paper are presented for the model working pair R134a-DMETEG. No changes were found in either of the phases over the course of the test. A computerized simulation program based on a single-stage absorption cycle containing a jet ejector as a mixer and preabsorber gave similar values of the COP for the three combinations, but the value of circulation ratio for R134a-DMETEG was lower than for the other two pairs. R134a-DMETEG was therefore the best of the three candidate working pairs.
