Definitions

  • the present invention has been made to solve such problems.
  • the temperature rise of the refrigerant with respect to the temperature rise of the exhaust gas is suppressed. Intended to provide a Rankine cycle.
  • the Rankine cycle 101 forms a circulation path that sequentially connects the pump 111, the cooling water boiler 112, the waste gas boiler 113, the expander 114, the condenser 115, the receiver 116, and the subcooler 117 in an annular fashion, and In the embodiment, R134a) is distributed.
  • the engine 10 (see FIG. 1) has a medium load and the exhaust gas temperature during operation of the Rankine cycle 101 circulates the Rankine cycle 101 in an average state (for example, about 500 to 600 ° C.).
  • the change of state of the refrigerant proceeds along a trapezoidal cycle S with the points A, B, C and D as apexes.
  • the process from the point A to the point B indicates the adiabatic pressurization process of the refrigerant by the pumping of the pump 111.
  • the refrigerant raises the pressure from the pressure Pa to the pressure Pb and raises the temperature, and the state maintains a liquid state (supercooled liquid state) in the subcooled liquid region SL.
  • a curve T 0 in FIG. 2 shows an isotemperature line of the temperature T 0 .
  • the temperature of the isotemperature line increases by 10 ° C. as it goes from the isotemperature line T 0 toward the isotemperature lines T 1 , T 2 , T 3 , T 4 , T 5 , T 6 , and T 7.
  • the temperature decreases by 10.degree. C. from 0 toward the isotemperature lines T.sub.- 1 , T.sub.- 2 , T.sub.- 3 , T.sub.- 4 and T.sub.- 5 .
  • the target pressure (target pressure line TPL) of the refrigerant with respect to the temperature detected by the temperature sensor 131 is stored in the ECU 140 in advance. Then, the ECU 140 adjusts the flow rate adjustment valve 130 such that the pressure detected by the pressure sensor 132 becomes the target pressure. That is, when the pressure detected by the pressure sensor 132 is lower than the target pressure, the ECU 140 decreases the degree of opening of the flow rate adjustment valve 130 to increase the flow rate of the refrigerant in the flow passage portion 1d, thereby the refrigerant in the flow passage portion 1d. The pressure (the pressure of the refrigerant drawn into the expander 114) is increased.
  • the upper limit pressure Pc may be set as In this case, when the refrigerant temperature rises above the temperature T5 corresponding to the upper limit pressure Pc in the target pressure line TPL, the target pressure is fixed to the upper limit pressure Pc as indicated by a broken line TPL '.
  • the ECU 140 responds to the temperature of the refrigerant falling at the temperature sensor 131. Then, the refrigerant pressure in the pressure sensor 132 is controlled so that the relationship between the temperature and the pressure of the refrigerant transitions along the target pressure line TPL. In control in which the temperature and pressure satisfy the relationship along the target pressure line TPL, the ECU 140 decreases the refrigerant temperature more than the state of the refrigerant in which the temperature and pressure decrease while satisfying the relationship on the isodensity line d0.
  • bypass flow path 3 connected between the condenser 115 and the sub cooler 117 is a pump cavitation (a bubble of refrigerant generated when the flow path portion 1 a is bypassed to the flow path portion 2 d between the sub cooler 117 and the pump 111 ) Can be prevented.
  • the bypass flow path 3 connected between the condenser 115 and the pump 111 is a refrigerant flowing into the condenser 115 which occurs when the flow path part 1 a is bypassed to the flow path part 2 a between the expander 114 and the condenser 115.
