• This paper presents the results of thermodynamic cycle analysis of the single-stage compression heat pump with solution circuit (CHPSC) and the absorption heat pump with booster compressor (AHPBC) with the new working pairs, i.e., R21-NMP, R22-NMP, R21-DMA and R22-DMA. The cycle analysis of a compression heat pump with R22 as the working fluid in also given for comparison. The analysis considers irrever-sibilities due to effectiveness and efficiency of components in the circuit. The coefficients of performance (COP) are fitted as functions of the low-grade source temperature, the temperature at which useful heat is obtained, and ambient temperature. R21-DMA in the AHPBC mode and R21-DMA and R21-NMP in the CHPSC mode yield the best performance. CHPSCs are suitable as peak thermal load units. AHPBCs are useful where temperatures higher than those provided by simple absorption or absorption-resorption heat pumps are desired.
