Abstract

PURPOSE:To enable to run a Rankine engine at ideal heat efficiency by a method wherein the rotational frequency of the liquid pump of the Rankine engine is controlled in inverse proportion to the power consumption of an auxiliary motor. CONSTITUTION:A heat collecting circuit 1 consists of a collector 2 and a heat transfer medium circulating pump 3. The Rankine engine 4 consists of an expansion engine 5, a condenser 6, the liquid pump 7 and a generator 8. A cooling cycle loop 9 comprises a compressor 10, a condenser 11, expansion evalve 12 and an evaporator 13. In the above-mentioned constitution, the liquid pump 7 is controlled in inverse proportion to the power consumption of the auxiliary motor 18 by means of a controlling circuir 20. Concretely, when the heat transfer medium outlet temperature of the collector 2 ascends, the power outputted from the Rankine engine 4 increases and the power consumption of the auxiliary motor 18 decreases. The rotational frequency of the liquid pump 7 increases in inverse proportion to the power consumption of the auxiliary motor 18. In such a manner as mentioned above, the Rankine engine is operated under the cycle most suitable for the collector outlet temperature.
