<p>PURPOSE: To obtain a temperature regulator and a regulating method for medium in which extreme oscillation is avoided and a stabilized control is realized within a narrow limit value. CONSTITUTION: A time lag circuit 11 is actuated upon occurrence of variation from falling to rising in a measurement signal. Another time lag circuit 12 is actuated upon occurrence of variation from rising to falling in the measurement signal. If the measurement signal exceeds an upper limit value TO upon elapsing the operating time of one time lag circuit 11, output stage of a compressors arrangement is switched on. If the measurement signal drops below a lower limit value Tu upon elapsing the operating time of another time lag circuit 12, output stage of the compressors is switched off.</p> |
