ABSTRACT:
In a Rankine-cycle-engine-driven cooling-and-heating system comprising a power generating cycle including at least an expander, an oil separator, a condenser and a generator and a cooling-and-heating cycle including at least a compressor, an oil separator, a condenser, an expansion means and an evaporator, the housings of the expander and the compressor are so securely joined that a hermetically sealed space may be defined between them. This space is used as an oil separator which is common to both the cycles and is communicated with the outlet port of the expander and the discharge port of the compressor. As a result, the system can be made considerably compact in size as compared with the prior art systems in which the oil separator is disposed outside of the expander and the compressor.
