   Author : Lena Åhlby; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The compression/absorption cycle can, in many situations,give an improved performance compared to the single-fluidcompression heat pump. Also other advantages can beachieved such as the possibility to use an already knownrefrigerant within a new temperature range. READ MORE

4. 2. The Compression/Absorption Heat Pump Cycle - System Simulations

   Author : Lena Åhlby; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression; refrigerant mixture; absorption; NH3 H2O; NH3 H2O-LiBr;

   Abstract : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. READ MORE
