A liquid cooling system for generating very cold liquid flows, comprising sending said liquid to a heat pump circuit; said circuit including a hot-side heat exchanger (HSHE) and a cold-side heat exchanger (CSHE); said CSHE being provided with conduit means through which said liquid flows; said conduit means being in contact with and being cooled externally by cold medium. The improvement in the system comprising the installation of proper thermal barriers between said cold medium and said liquid in all areas where the velocity of said liquid is much lower than the average velocity found inside said conduit means; said improvement also comprising proper design of the entrance of said conduit means to prevent flow detachment; said design preventing any freeze-up of said liquid as well as improving efficiency and durability. An alternative to the above said improvement is simply the elimination of all areas where the velocity of said liquid is much lower than the average velocity found inside said conduit means. Other alternatives are proposed. The improvement in the system also comprising the capability to generate and manipulate supercooled liquids in a way that prevents liquid line and cooler freeze-ups. The improvement in the system also comprising new vapor compression cycles as well as new absorption cycle arrangements for better practicing the described method. Applications in very diversified fields are described. The technology is given the name "SUPERPAC", which stands for "SUPER Pompe A Chaleur", or super heat pump.
