A new definition of the exergy efficiency for two types of Sorption Heat Pumps (type I or conventional heat pump and type II or heat transformer) is presented. It is based on the concept of transiting exergy which permits the quantitative and non ambiguous definition of the useful exergy...

The reversed rectification heat pump (RRHP) is a novel type of absorption heat pump developed at Laboratoire des sciences du génie chimique (LSGC) in the research group of Professor Le Goff. The distinctive characteristic of the RRHP is that both the separator and the absorber are multi-stage...

A dynamic simulation model, based upon the thermal-electrical analogy, has been developed to simulate the free thermal behavior of a solar greenhouse. The simple linearized model treats greenhouse air and ground temperatures as lumped parameters. It requires only six input parameters, which were...
