Development of COP-10 Adsorption Heat Pump with Electric Power

通过提高电厂的运行率，或利用余热，来实现夜间用电的负荷平衡和节能降耗。为了克服这几个方面的问题，本文开展了以最小外功率吸附式热泵为主体的新型系统的研究工作。可以说，对于这种吸附式热泵来说，最好的外部电源是机械增压泵和微波，因此，对这两种电源进行了研究，1999年，将硅胶/水吸附式热泵与300 W电功率的机械增压泵连接起来，研究了该功率的影响。结果表明，在不提高吸附剂温度的情况下，采用机械增压泵可提高吸附速率，因此，增加动力是可行的。2000年，设计了实验型硅胶/水体系热重吸附器，以评价不同微波功率水平对提高脱附率的影响。结果表明，微波对吸附水具有选择性加热作用，当微波功率大于1 kW时，吸附水的解吸率明显提高。在1 kW的微波辐射条件下，解吸量与无微波辐射时相同，但解吸周期缩短，为开发高性能吸附热泵系统做出了贡献。

It is highly expected that load leveling of night electricity and energy saving, which can be achieved by upgrading operation ratio of power plant, or by utilizing of waste heat. In order to overcome in these several problems, the research work which is concerned about new system, mainly consists of adsorption heat pump with minimum external power, was carry out. It can be said that some of the best external power for this adsorption heat pump are mechanical booster pump and microwave, therefore, these two kind of the power were investigated.In 1999, silica-gel/water-adsorption heat pump with mechanical booster pump of 300W electrical power was connected and effect of that power was studied. As a result, adsorption rate increased by utilizing mechanical booster pump without increasing temperature of adsorbent, therefore, the addition of the power found to be applicable. In 2000, experimental type of silica-gel/water system thermogravimetric adsorber was designed to evaluate effect of several level of microwave power for enhancing desorption rate. Is was found that adsorbed water was heated by microwave selectively, and when microwave over 1kW radiated continuously, desorption rate of adsorbed water increased effectively. Under the condition of 1kW microwave radiation, it was found that amount desorbed was same as without microwave, however, desorption period was decreased.From these results, it can be concluded that this research work has made a contribution in the development of the advanced high COP adsorption heat pump system.
