Opis:: The article discusses the problems related to the operation of various types of expansion devices used in small cogeneration systems. Both volumetric and dynamic expanders were considered, including scroll, screw, vane, piston and turbine expanders. For each of these solutions, principles of operation were explained as well as major advantages and disadvantages. The results of experimental research on several expanders of various types were also presented. The overview of expanders included in this paper, along with basic operational problems and functional characteristics, is the collection of valuable information facilitating selection of a suitable expander for speciﬁc applications. This is particularly important in the context of search for new energy sources and opportunities to improve the energy eﬃciency of available energy resources.

Opis:: In the paper presented are experiences from operation of three different expansion devices for possible implementation in the domestic micro CHP. These were the modified scroll expander and two designs based on the variable working chamber volume pneumatic devices. Experiments showed the superiority of both "pneumatic devices" over the scroll expander, indicating the possible internal efficiencies in the range of 61 82Such efficiencies are very attractive, especially at the higher end of that range. The volume of these devices is much smaller than the scroll expander which makes it again more suitable for a domestic micro CHP. Small rotational velocities enable to conclude that connection to electricity grid will also be simpler in the case of "pneumatic devices". The "pneumatic devices" under scrutiny here could be an alternative to the typical vapour turbine in the ORC cycle, which is in the process of development at the IFFM.
