Abstract
A temperature controller for controlling the tube wall temperature of a heater for absorbing heat during Stirling engine operation includes an operator circuit setting a pre-set temperature based on the pressure of the high pressure working medium. Such preset temperature is transmitted to an air-fuel rate controller for controlling the temperature at the heater to keep an optimal working condition of the engine.
Claims2
A temperature control system for a Stirling cycle engine, comprising:
- an expansion space having a relatively high mean temperature during operation;
- a compression space having a relatively low mean temperature during operation;
- a heater, a regenerator and a heat radiator disposed between said spaces in series, the heater having at least one tube;
- and
- a temperature controller for controlling the tube wall temperature of said heater, said temperature controller including:
- an operator device setting a predetermined temperature for said heater based on the working gas pressure, whereby said tube wall temperature of said heater is controlled to said predetermined temperature;
- a pressure sensor for sensing the pressure of a working gas during operation and sending a signal to said operator device for deciding said predetermined temperature;
- wherein said pressure sensor is connected to the expansion space and is disposed at a connecting portion between the expansion space and a gas pressure controller for controlling the gas pressure in the expansion space.
