A system for providing a cold environment which has a number of cooling stages with variable displacement volumes into which input fluid from a compressor flows in an input channel to and from the displacement volumes and output fluid flows in an output channel to the compressor. Volume changers vary the volumes of the displacement volumes and input fluid flowing to a first set of displacement volumes is pre-cooled by regenerative heat exchange and counterflow heat exchange and input fluid flowing to the final displacement volume is pre-cooled primarily by counterflow heat exchange. The volume changer at at least one of the stages is thermally decoupled from the input and output channels.
