Absorption heat pump absorber unit and absorption method

An absorber unit for an absorption heat pump system comprising:

• a housing defining an interior absorption space and having a first end, a second end, a first inlet adjacent the first end, a second inlet adjacent the second end and an outlet adjacent the second end, and
• a plurality of heat exchange elements located within said housing forming a plurality of pathway portions located in heat exchange relation with said interior absorption space and with said absorber housing for withdrawing heat from said interior absorption space when absorption occurs in said interior absorption space;
• with some of said plurality of pathway portions being joinable into a first pathway for conducting a coolant and the remainder of said plurality of pathway portions being joinable into a second pathway for conducting rich liquor;
• said second pathway communicating with said outlet and said plurality of pathway portions dividing said interior absorption space into a plurality of absorption zones, with each pathway portion being sealed off from and in heat exchange relation with an adjacent absorption zone for thorough mixing and absorption in said absorption zones and a high level of heat exchange into said pathway portions.
