Abstract
This disclosure relates to a heat pump including a plurality of interconnected elements, each of said elements comprising a piston body having an evaporator section at one end thereof and a condenser section at the other end thereof, each condenser section being connected to a vapor condenser. Each element has its evaporator section connected by a vapor bridge to the condenser of an adjacent element. Each piston body contains a working fluid having a liquid phase and a vapor phase, the liquid phase forming a liquid piston which oscillates during operation and the pistons of the elements oscillating with a phase displacement. The evaporator sections are located in relatively warm areas and the condensers are located in another cooler area. Portions of the liquid in the evaporator sections vaporize and the vapor is heated, and the heated vapor is condensed in the condensers thereby transferring heat from the warm areas to the cooler areas.
