摘要

"The office refrigerator isolated vacuum, and a method for estimating the thermal conductivity of an area of isolation of a cabinet of refrigerator isolated vacuum".A refrigerator cabinet includes an insulated vacuum evacuation system for evacuating a space of insulation (10),(12) of the cabinet when the pressure in this space is higher than a predetermined value.The cabinet has the middle sensor including a temperature sensor (14) and a heater (18), both located within the insulation space (10),12) and a control system (16) to activate the heater (18) according to a predetermined heating cycle and to receive a signal from the temperature sensor (14).Such a control system being able to arrange the evacuation system with a signal related to the level of insulation within the insulation space.
