Abstract: A power plant with heat transfer, in which power is generated by an arbitrary number of heat engines, described above and illustrated in FIGS. 1 to 18. is disclosed. The heat engines (A) are arranged in series with a cooling medium (22) and a heating medium (30) passing through them in a counter flow principal. After exiting the last heat engine the heated-up cooling medium is used as a combustion air. The heating medium (30) exiting in the opposite direction the last heat engine (A) can be used further on for heating purposes or other heating consumers.

Abstract: A refrigerator is disclosed that consists in contrast to conventional refrigerators of a number of heat exchangers that are separated into halves, in which the same refrigeration cycle process takes place simultaneously but chronologically displaced, and wherein all heat exchangers are driven the same compressor. A cold medium flows about one half of the heat exchanger (evaporator) at certain time periods, a hot medium flows about the other half of the heat exchanger (condenser). The refrigeration cycle process consists of six changes of state: isochoric heat input, isothermal expansion, isobaric condensation, isochoric heat extraction, isothermal compression and isobaric evaporation. In the disclosed embodiment, the compressor is a double acting piston compressor establishing a connection to the heat exchangers via valves on both sides of the piston at predefined points in time within a cycle period. The piston is driven by a linear motor or by a crank shaft and a piston rod.
