    摘要: A temperature control method for a heated breathing-circuit includes steps of: continuously controlling the heated breathing-circuit to be heated continuously in a first predetermined time period; obtaining a sampling temperature signal of the heated breathing-circuit in a second predetermined time period; obtaining a resistance value of a temperature sensing loop by converting the sampling temperature signal; controlling the temperature-sampling circuit to be electrically connected with the short-circuit loop in a third predetermined time period, to obtain an internal resistance value of the temperature-sampling circuit; obtaining a resistance value of the temperature sensor thought the resistance value of the temperature sensing loop, a resistance value of the resistance wire, and the internal resistance; and calculating the resistance value of the temperature sensor and the temperature of the temperature sensor, to obtain an actual temperature value of the heated breathing-circuit. A temperature control system for a heated breathing-circuit is also provided.
