Abstract
This invention discloses a refrigerator and its environmental humidity measurement method. The environmental humidity during the current door opening period is calculated by substituting the acquired parameters into a first preset function formula. The embodiments of this invention can calculate the environmental humidity based on the change in the evaporation temperature of the evaporator before and after the refrigerator door is opened, without the need for an additional humidity sensor for monitoring the environmental humidity, thus saving time and manpower in refrigerator production.
