Abstract
The invention discloses a constant-temperature control method and system for a smell sensor chip in a refrigerator and the refrigerator, and the method comprises the steps: when at least one piece of information of a door opening and closing signal of the refrigerator, the volume of a put-in article and the temperature of the put-in article is received, according to the received information and current environment temperature information, controlling the temperature of the put-in article; inquiring a pre-stored heating power adjustment coefficient of the heating device; according to the adjustment coefficient, before the refrigeration cycle of the refrigerator starts, the heating power of the heating device is adjusted, the heating device is preheated, and the heating device is used for heating the smell sensor chip. The heating device is arranged on the smell sensor chip, and the adjustment coefficient is set for the heating power of the heating device based on the factors influencing the refrigeration cycle of the refrigerator, so that the working temperature of the gas sensitive chip of the smell sensor is kept consistent, and the gas detection accuracy of the sensor is improved.
