A heat energy transfer system including a refrigeration loop with a heat transfer engine connected in series with a condenser, a thermal expansion valve and an evaporator has associated with the evaporator a heat exchanger that is coupled in circuit with a container of water or other-suitable heat transfer fluid. The warmer fluid proximate the top of the container is drawn off and fed through the heat exchanger and returned to the bottom of the container. The thus chilled fluid can be pumped to utilization devices again with the colder fluid at the bottom of the buffer or container being pumped to the utilization device and returned, after warming, to the top of the container. An auxiliary closed exchange loop may also be incorporated to supply heat energy needs to the evaporator of the refrigeration loop in the event that the cold buffer contents are chilled to the point where insufficient heat energy is contained in it to provide evaporization of the refrigerant before being fed to the heat transfer engine.
