な運転を行なうことを目的とする。Detailed Description of the Invention The present invention detects and compares the temperature of the generator section and the temperature of the condenser section in a Rankine type air conditioner that uses a heat medium heated by solar heat as a heating source, and stops the operation of the Rankine engine. The purpose is to disconnect the expander and compressor and stop the operation of the heat medium circulation pump for efficient operation.

発明は上述の問題点を解消を図つたものである。 Previously, the circulation pump and Rankine engine were operated regardless of the temperature conditions in the generator and condenser. Therefore, even if the temperature of the generator is not higher than the temperature of the condenser and the temperature difference disappears, or if it becomes lower (i.e., the output of the Rankine engine is lost), the circulation pump and liquid pump will continue to operate. However, it consumed electricity unnecessarily, and since it was connected to a Rankine engine, it had the disadvantage of becoming a load power. The present invention aims to solve the above-mentioned problems.

に引離し信号を出す手段を有している。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a collector, which collects solar heat and heats a heat medium. 2 is a heat medium circulation pump, 3 is a heat collection circuit, and 4 is a generator, which heats a working fluid with a heat medium and generates high-pressure steam. 5 is an expander, which generates the output of a Rankine engine. 6 is a condenser of the Rankine engine 8; 7 is a liquid pump that circulates the working fluid of the Rankine engine; 11 is a cooling cycle, which is composed of a compressor 15, a condenser 16, an expansion valve 17, and an evaporator 18. Reference numeral 10 denotes an auxiliary electric motor that transmits auxiliary power when the output of the Rankine engine falls below a predetermined value.
A clutch 9 serves as a transmission device between the expander 5 and the compressor 15, and connects or disconnects the output of the Rankine engine to the compressor 15. A first temperature sensor 12 detects the temperature at the generator 4. A second temperature sensor 13 detects the temperature in the condenser 6. First and second temperature sensors 12, 13
is the heating medium or working fluid in the generator 4, and the condenser 6
Detects the temperature of the working fluid or cooling water.
14 is a control circuit which receives signals from the first temperature sensor 12 and the second temperature sensor 13;
If the temperature of the first temperature sensor 12 is lower than the temperature of the second temperature sensor 13, a stop signal is issued to the heat medium circulation pump and the liquid pump 7 of the Rankine engine 8, and the clutch 9 as a transmission device is activated.
It has means for issuing a pull-off signal.

め、クラツチ９に引離し信号を出す。 When the Rankine engine air conditioner is put into operation by, for example, a manual switch, the first temperature sensor 12 detects the temperature of the generator 4. The first temperature sensor 13 then detects the temperature of the condenser 6.
If the generator temperature t 1 <condenser temperature t 2 , there is no solar heat collection and the Rankine engine will not produce output, so the compressor 15 should be driven entirely by the auxiliary motor 10. become. Therefore, the control circuit 14 issues a stop signal to the circulation pump 2, and also issues a stop signal to the liquid pump 7 in order to stop the Rankine engine as well. Furthermore, since there is no output from the Rankine engine, a release signal is sent to clutch 9.

ある。 Conventionally, even when there was no solar heat collection, the heat medium circulation pump 2 and liquid pump 7 were also operated, and the Rankine engine and compressor 15 continued to be connected, resulting in wasted power consumption and, moreover, the Rankine engine was used as the load power. On the other hand, the operation control method of the solar heat-using Rankine engine type air conditioner in the example was that until now the sun was shining and heat was collected, but due to cloudy skies and the amount of solar heat collection disappeared, Rankine When the engine is not generating output, the heat medium circulation pump 2 and the liquid pump 7 are stopped, so power is not wasted, and the clutch 9 is also disengaged, so the Rankine engine does not become a load power. This results in extremely efficient operation.
