Abstract/Summary:
This research investigates an intermittent compression system for a heat pump Utilizing Refrigerant 12 and Type Linde l3X molecular sieve.; After a brief introduction, an overview of research in the field is discussed, and the available literature is summarized. This includes intermittent compression systems, refrigerants, and adsorbents.; A mathematical model for the various physical mechanisms involved and the conservation equations are developed. Experimental and numerical results are acquired. The derivation of the basic heat transfer equations within the porous molecular sieve and a finite-difference solution are formulated.; The results of both experimental and theoretical work and the theoretical implications of this project are detailed.; The intermittent heat compression system uses waste heat or a low-grade thermal energy and does not have moving parts, and thereby is technically applicable. The primary problem is the heat transfer during the adsorption and regeneration processes. This research advances the development of the intermittent heat pump system.
