Heat pumps can efficiently upgrade waste heat from the industry and in that way reduce emissions. One of the main reasons why heat pumps are not applied to a greater extent in industry are large payback periods. Compression–resorption heat pumps (CRHP) enhanced by wet compression are considered a very promising option that can have higher coefficient of performance compared to traditional technologies when the heat source and/or sink have a large temperature glide. In this study the thermodynamic and economic performance of two potential industrial cases are examined for CRHP operating with NH₃–H₂O and NH₃–CO₂–H₂O. A detailed thermodynamic model of the compressor is used to evaluate the isentropic efficiency for each case. The results are used to calculate the simple payback period, when a boiler is replaced by a CRHP, as a function of the predicted gas and electricity prices in the Netherlands from 2020 to 2035. The results indicate that adding CO₂ to the NH₃–H₂O mixture increases the cycle COP when the temperature glide of the heat sink is 40 K while the opposite occurs when the glide is 80 K. The highest COPs and lowest payback times are obtained when the outlet vapor quality is around 0.50 for both the binary and ternary mixtures. Larger glides require higher outlet qualities. However, it is clear that even for high temperature glides the payback period can be within acceptable limits, especially if the cost of CO₂ emissions is taken into account.

热泵可以有效地提升行业废热，从而减少排放。热泵在工业上不被广泛使用的主要原因之一是投资回收期长。通过湿压缩增强的压缩吸收式热泵（CRHP）被认为是非常有前途的选择，与传统技术相比，当热源和/或散热器的温度滑移较大时，其性能系数更高。在这项研究中，研究了使用NH ₃ –H ₂ O和NH ₃ –CO ₂ –H _2的CRHP的两个潜在工业案例的热力学和经济性能。O.压缩机的详细热力学模型用于评估每种情况下的等熵效率。根据荷兰到2020年至2035年的预计天然气和电力价格，该结果可用于计算将锅炉替换为CRHP时的简单投资回收期。结果表明，向NH ₃中添加CO ₂ –高₂当散热器的温度滑动量为40 K时，O混合物会增加循环COP，而当滑动量为80 K时，O混合物会增加循环COP。当二元气和二元气的出口蒸气质量均为0.50左右时，可获得最高的COP和最低的回收时间。三元混合物。较大的滑行需要更高的出口质量。但是，很明显，即使对于高温滑行，投资回收期也可以在可接受的范围内，尤其是如果考虑到CO ₂排放成本的话。
