| Abstract: | The theoretical performance characteristics of single-stage and double-stage heat transformers using aqua-ammonia as binary mixture have been discussed. The coefficients of performance, energy efficiencies, mass circulation ratio, pump work etc. have been analysed as a function of heat delivery temperature. Thus, heat transformers represent an attractive solution for upgrading low temperature waste heat to higher temperature useful heat with minimum consumption of external energy. |
