吸收式热泵可以用来回收废热,制取高温水,用于采暖以及生产等场合,对节约一次能源起着非常重要的作用。其中第Ⅰ类热泵(AHP)以增热为目的,第Ⅱ类热泵(AHT)以增温为目的,通过分析利用吸收—重吸收循环可以实现AHP与AHT两种形式热泵的切换,本文对此进行了初步的理论分析与研究。 Absorption heat pump can be used to recover waste heat, making high-temperature water for heating and production and other occasions, to save primary energy plays a very important role. The first type of heat pump (AHP) aims at increasing heat. The second type of heat pump (AHT) aims at increasing temperature. By analyzing the use of absorption-reabsorption cycle, AHP and AHT heat pump switching can be realized. In this paper, Conducted a preliminary theoretical analysis and research.
