ABSTRACT:
A method and a device for converting low temperature heat energy into mechanical or electrical energy, wherein at least one liquid or gas chamber performs work in response to temperature variations. According to the invention one or more expansible and compressible containers are arranged in said chamber. Each container contains a refrigerant capable of shifting from liquid phase to gas phase, and vice versa, thereby producing or contributing the work of the working gas or liquid. The refrigerant is alternatingly heat exchanged with two sources of low temperature heat energy, for example ground accumulators, of different temperatures, thereby causing alternating expansion and contraction of said containers.
