Influence of adsorption and desorption capacity on operating process for adsorption heat pump

A continuous heat recovery adsorption heat pump prototype using actived carbon–methanol pair has been developed. A lot of experiments have been carried out in order to realize good performance of the system. After analysis of these experimental data, it is seen that operating process of the system, which is shown in p–t–x diagram of the real cycle and temperature rise and drop curves of adsorber, is related to adsorption and desorption capacity. If these relations are realized, the degree of adsorption and desorption process can be judged. In this paper, the relation between adsorption and desorption capacity of adsorber and p–t–x diagram of the real cycle are analyzed. Meanwhile, the relation between adsorption and desorption capacity of adsorber and temperature rise and drop curves of adsorber are also discussed. This work has laid a foundation for optimization of cycle time and cycle process.
