Double-lift parallel mode absorption heat transformer with the ternary working fluid TFE-H2O-E181.

Author(s) : XU S. M., ZHANG L.

Summary

The paper gives thermal property expression formulae of 2,2,2-trifluoroethanol (TFE)-water (H2O)-tetraethylene glycol dimethyl ether (TEGDME or E181), which can be used for absorption heat transformer as ternary working fluid. The double-lift parallel mode absorption heat transformer using TFE-H2O-E181 as working fluid is proposed in order to upgrade low-temperature level heat energy to a high level and recover more heat energy in low-temperature level waste heat. The temperature of the available waste heat can drop nearly to 40°C while cooling water is 28°C, which takes the cost of reducing the COP of the heat transformer.
