Method and the device which detect the temperature rise of the low temperature interior

摘要

This invention relates to the method of detecting the rise of temperature (especially, retention temperature) inside the refigerating plant which is designed in order to retain the product, this method is due to temperature rise, the detection substance which is accommodated in the 1st cell (2) (6) it includes with liquefaction and the detection substance which liquefies to the 2nd cell (3) (6) movement from the 1st cell, detection of the aforementioned temperature rise becomes possible with that. This invention the device which executes method relates to also (1).
