TURBINE CONTROL METHOD FOR EXHAUST HEAT RECOVERY SYSTEM

摘要

According to the present invention, a turbine control method for an exhaust heat recovery system comprises: a normal rotation step of rotating a turbine in a normal direction by means of a working fluid to produce energy; a step of measuring a temperature of the working fluid; and a reverse rotation step of rotating the turbine in a reverse direction when the measured temperature is less than a predetermined temperature. Provided is the turbine control method for an exhaust heat recovery system, which prevents damage to a turbine due to a liquid state of a working fluid remaining inside the turbine. Thus, as the damage to the turbine is prevented, efficiency of an exhaust heat recovery system can be increased.
